-Asm, typically invoked as ``go tool asm'', assembles the source file into an object
-file named for the basename of the argument source file with a .o suffix. The
-object file can then be combined with other objects into a package archive.
-
-Command Line
-
-Usage:
-
- go tool asm [flags] file
-
-The specified file must be a Go assembly file.
-The same assembler is used for all target operating systems and architectures.
-The GOOS and GOARCH environment variables set the desired target.
-
-Flags:
-
- -D value
- predefined symbol with optional simple value -D=identifier=value;
- can be set multiple times
- -I value
- include directory; can be set multiple times
- -S print assembly and machine code
- -debug
- dump instructions as they are parsed
- -dynlink
- support references to Go symbols defined in other shared libraries
- -o string
- output file; default foo.o for /a/b/c/foo.s
- -shared
- generate code that can be linked into a shared library
- -trimpath string
- remove prefix from recorded source file paths
-
-Input language:
-
-The assembler uses mostly the same syntax for all architectures,
-the main variation having to do with addressing modes. Input is
-run through a simplified C preprocessor that implements #include,
-#define, #ifdef/endif, but not #if or ##.
-
-For more information, see https://golang.org/doc/asm.

-/*
-Compile, typically invoked as ``go tool compile,'' compiles a single Go package
-comprising the files named on the command line. It then writes a single
-object file named for the basename of the first source file with a .o suffix.
-The object file can then be combined with other objects into a package archive
-or passed directly to the linker (``go tool link''). If invoked with -pack, the compiler
-writes an archive directly, bypassing the intermediate object file.
-
-The generated files contain type information about the symbols exported by
-the package and about types used by symbols imported by the package from
-other packages. It is therefore not necessary when compiling client C of
-package P to read the files of P's dependencies, only the compiled output of P.
-
-Command Line
-
-Usage:
-
- go tool compile [flags] file...
-
-The specified files must be Go source files and all part of the same package.
-The same compiler is used for all target operating systems and architectures.
-The GOOS and GOARCH environment variables set the desired target.
-
-Flags:
-
- -D path
- Set relative path for local imports.
- -I dir1 -I dir2
- Search for imported packages in dir1, dir2, etc,
- after consulting $GOROOT/pkg/$GOOS_$GOARCH.
- -L
- Show complete file path in error messages.
- -N
- Disable optimizations.
- -S
- Print assembly listing to standard output (code only).
- -S -S
- Print assembly listing to standard output (code and data).
- -V
- Print compiler version and exit.
- -asmhdr file
- Write assembly header to file.
- -complete
- Assume package has no non-Go components.
- -cpuprofile file
- Write a CPU profile for the compilation to file.
- -dynlink
- Allow references to Go symbols in shared libraries (experimental).
- -e
- Remove the limit on the number of errors reported (default limit is 10).
- -h
- Halt with a stack trace at the first error detected.
- -importmap old=new
- Interpret import "old" as import "new" during compilation.
- The option may be repeated to add multiple mappings.
- -installsuffix suffix
- Look for packages in $GOROOT/pkg/$GOOS_$GOARCH_suffix
- instead of $GOROOT/pkg/$GOOS_$GOARCH.
- -l
- Disable inlining.
- -largemodel
- Generate code that assumes a large memory model.
- -linkobj file
- Write linker-specific object to file and compiler-specific
- object to usual output file (as specified by -o).
- Without this flag, the -o output is a combination of both
- linker and compiler input.
- -memprofile file
- Write memory profile for the compilation to file.
- -memprofilerate rate
- Set runtime.MemProfileRate for the compilation to rate.
- -msan
- Insert calls to C/C++ memory sanitizer.
- -nolocalimports
- Disallow local (relative) imports.
- -o file
- Write object to file (default file.o or, with -pack, file.a).
- -p path
- Set expected package import path for the code being compiled,
- and diagnose imports that would cause a circular dependency.
- -pack
- Write a package (archive) file rather than an object file
- -race
- Compile with race detector enabled.
- -trimpath prefix
- Remove prefix from recorded source file paths.
- -u
- Disallow importing packages not marked as safe; implies -nolocalimports.
-
-There are also a number of debugging flags; run the command with no arguments
-for a usage message.
-
-Compiler Directives
-
-The compiler accepts compiler directives in the form of // comments at the
-beginning of a line. To distinguish them from non-directive comments, the directives
-require no space between the slashes and the name of the directive. However, since
-they are comments, tools unaware of the directive convention or of a particular
-directive can skip over a directive like any other comment.
-
- //line path/to/file:linenumber
-
-The //line directive specifies that the source line that follows should be recorded
-as having come from the given file path and line number. Successive lines are
-recorded using increasing line numbers, until the next directive. This directive
-typically appears in machine-generated code, so that compilers and debuggers
-will show lines in the original input to the generator.
-
-The //line directive is an historical special case; all other directives are of the form
-//go:name, indicating that the directive is defined by the Go toolchain.
-
- //go:noescape
-
-The //go:noescape directive specifies that the next declaration in the file, which
-must be a func without a body (meaning that it has an implementation not written
-in Go) does not allow any of the pointers passed as arguments to escape into the
-heap or into the values returned from the function. This information can be used
-during the compiler's escape analysis of Go code calling the function.
-
- //go:nosplit
-
-The //go:nosplit directive specifies that the next function declared in the file must
-not include a stack overflow check. This is most commonly used by low-level
-runtime sources invoked at times when it is unsafe for the calling goroutine to be
-preempted.
-
- //go:linkname localname importpath.name
-
-The //go:linkname directive instructs the compiler to use ``importpath.name'' as the
-object file symbol name for the variable or function declared as ``localname'' in the
-source code. Because this directive can subvert the type system and package
-modularity, it is only enabled in files that have imported "unsafe".

-/*
-1) Export data encoding principles:
-
-The export data is a serialized description of the graph of exported
-"objects": constants, types, variables, and functions. Aliases may be
-directly reexported, and unaliased types may be indirectly reexported
-(as part of the type of a directly exported object). More generally,
-objects referred to from inlined function bodies can be reexported.
-We need to know which package declares these reexported objects, and
-therefore packages are also part of the export graph.
-
-The roots of the graph are two lists of objects. The 1st list (phase 1,
-see Export) contains all objects that are exported at the package level.
-These objects are the full representation of the package's API, and they
-are the only information a platform-independent tool (e.g., go/types)
-needs to know to type-check against a package.
-
-The 2nd list of objects contains all objects referred to from exported
-inlined function bodies. These objects are needed by the compiler to
-make sense of the function bodies; the exact list contents are compiler-
-specific.
-
-Finally, the export data contains a list of representations for inlined
-function bodies. The format of this representation is compiler specific.
-
-The graph is serialized in in-order fashion, starting with the roots.
-Each object in the graph is serialized by writing its fields sequentially.
-If the field is a pointer to another object, that object is serialized in
-place, recursively. Otherwise the field is written in place. Non-pointer
-fields are all encoded as integer or string values.
-
-Some objects (packages, types) may be referred to more than once. When
-reaching an object that was not serialized before, an integer _index_
-is assigned to it, starting at 0. In this case, the encoding starts
-with an integer _tag_ < 0. The tag value indicates the kind of object
-that follows and that this is the first time that we see this object.
-If the object was already serialized, the encoding is simply the object
-index >= 0. An importer can trivially determine if an object needs to
-be read in for the first time (tag < 0) and entered into the respective
-object table, or if the object was seen already (index >= 0), in which
-case the index is used to look up the object in the respective table.
-
-Before exporting or importing, the type tables are populated with the
-predeclared types (int, string, error, unsafe.Pointer, etc.). This way
-they are automatically encoded with a known and fixed type index.
-
-2) Encoding format:
-
-The export data starts with two newline-terminated strings: a version
-string and either an empty string, or "debug", when emitting the debug
-format. These strings are followed by version-specific encoding options.
-
-(The Go1.7 version starts with a couple of bytes specifying the format.
-That format encoding is no longer used but is supported to avoid spurious
-errors when importing old installed package files.)
-
-This header is followed by the package object for the exported package,
-two lists of objects, and the list of inlined function bodies.
-
-The encoding of objects is straight-forward: Constants, variables, and
-functions start with their name, type, and possibly a value. Named types
-record their name and package so that they can be canonicalized: If the
-same type was imported before via another import, the importer must use
-the previously imported type pointer so that we have exactly one version
-(i.e., one pointer) for each named type (and read but discard the current
-type encoding). Unnamed types simply encode their respective fields.
-Aliases are encoded starting with their name followed by the qualified
-identifier denoting the original (aliased) object, which was exported
-earlier.
-
-In the encoding, some lists start with the list length. Some lists are
-terminated with an end marker (usually for lists where we may not know
-the length a priori).
-
-Integers use variable-length encoding for compact representation.
-
-Strings are canonicalized similar to objects that may occur multiple times:
-If the string was exported already, it is represented by its index only.
-Otherwise, the export data starts with the negative string length (negative,
-so we can distinguish from string index), followed by the string bytes.
-The empty string is mapped to index 0. (The initial format string is an
-exception; it is encoded as the string bytes followed by a newline).
-
-The exporter and importer are completely symmetric in implementation: For
-each encoding routine there is a matching and symmetric decoding routine.
-This symmetry makes it very easy to change or extend the format: If a new
-field needs to be encoded, a symmetric change can be made to exporter and
-importer.
-
-3) Making changes to the encoding format:
-
-Any change to the encoding format requires a respective change in the
-exporter below and a corresponding symmetric change to the importer in
-bimport.go.
-
-Furthermore, it requires a corresponding change to go/internal/gcimporter
-and golang.org/x/tools/go/gcimporter15. Changes to the latter must preserve
-compatibility with both the last release of the compiler, and with the
-corresponding compiler at tip. That change is necessarily more involved,
-as it must switch based on the version number in the export data file.
-
-It is recommended to turn on debugFormat temporarily when working on format
-changes as it will help finding encoding/decoding inconsistencies quickly.

-// Run analysis on minimal sets of mutually recursive functions

-// by reverse topological order in the static call graph.
-// The algorithm (known as Tarjan's algorithm) for doing that is taken from
-// Sedgewick, Algorithms, Second Edition, p. 482, with two adaptations.
-//
-// First, a hidden closure function (n.Func.IsHiddenClosure) cannot be the
-// root of a connected component. Refusing to use it as a root
-// forces it into the component of the function in which it appears.
-// This is more convenient for escape analysis.
-//
-// Second, each function becomes two virtual nodes in the graph,
-// with numbers n and n+1. We record the function's node number as n
-// but search from node n+1. If the search tells us that the component
-// number (min) is n+1, we know that this is a trivial component: one function
-// plus its closures. If the search tells us that the component number is
-// n, then there was a path from node n+1 back to node n, meaning that
-// the function set is mutually recursive. The escape analysis can be
-// more precise when analyzing a single non-recursive function than
-// when analyzing a set of mutually recursive functions.

-//
-// First escfunc, esc and escassign recurse over the ast of each
-// function to dig out flow(dst,src) edges between any
-// pointer-containing nodes and store them in e.nodeEscState(dst).Flowsrc. For

-// gvardef inserts a VARDEF for n into the instruction stream.
-// VARDEF is an annotation for the liveness analysis, marking a place
-// where a complete initialization (definition) of a variable begins.
-// Since the liveness analysis can see initialization of single-word
-// variables quite easy, gvardef is usually only called for multi-word
-// or 'fat' variables, those satisfying isfat(n->type).
-// However, gvardef is also called when a non-fat variable is initialized
-// via a block move; the only time this happens is when you have
-// return f()
-// for a function with multiple return values exactly matching the return
-// types of the current function.
-//
-// A 'VARDEF x' annotation in the instruction stream tells the liveness
-// analysis to behave as though the variable x is being initialized at that
-// point in the instruction stream. The VARDEF must appear before the
-// actual (multi-instruction) initialization, and it must also appear after
-// any uses of the previous value, if any. For example, if compiling:
-//
-// x = x[1:]
-//
-// it is important to generate code like:
-//
-// base, len, cap = pieces of x[1:]
-// VARDEF x
-// x = {base, len, cap}
-//
-// If instead the generated code looked like:
-//
-// VARDEF x
-// base, len, cap = pieces of x[1:]
-// x = {base, len, cap}
-//
-// then the liveness analysis would decide the previous value of x was
-// unnecessary even though it is about to be used by the x[1:] computation.
-// Similarly, if the generated code looked like:
-//
-// base, len, cap = pieces of x[1:]
-// x = {base, len, cap}
-// VARDEF x
-//
-// then the liveness analysis will not preserve the new value of x, because
-// the VARDEF appears to have "overwritten" it.
-//
-// VARDEF is a bit of a kludge to work around the fact that the instruction
-// stream is working on single-word values but the liveness analysis
-// wants to work on individual variables, which might be multi-word
-// aggregates. It might make sense at some point to look into letting
-// the liveness analysis work on single-word values as well, although
-// there are complications around interface values, slices, and strings,
-// all of which cannot be treated as individual words.
-//
-// VARKILL is the opposite of VARDEF: it marks a value as no longer needed,
-// even if its address has been taken. That is, a VARKILL annotation asserts
-// that its argument is certainly dead, for use when the liveness analysis

-This is a list of things that need to be worked on. It will hopefully
-be complete soon.
-
-Correctness
------------
-- Debugging info (check & fix as much as we can)
-
-Optimizations (better compiled code)
-------------------------------------
-- Reduce register pressure in scheduler
-- More strength reduction: multiply -> shift/add combos (Worth doing?)
-- Add a value range propagation pass (for bounds elim & bitwidth reduction)
-- Make dead store pass inter-block
-- If there are a lot of MOVQ $0, ..., then load
- 0 into a register and use the register as the source instead.
-- Allow arrays of length 1 (or longer, with all constant indexes?) to be SSAable.
-- If strings are being passed around without being interpreted (ptr
- and len fields being accessed) pass them in xmm registers?
- Same for interfaces?
-- Non-constant rotate detection.
-- Do 0 <= x && x < n with one unsigned compare
-- nil-check removal in indexed load/store case:
- lea (%rdx,%rax,1),%rcx
- test %al,(%rcx) // nil check
- mov (%rdx,%rax,1),%cl // load to same address
-- any pointer generated by unsafe arithmetic must be non-nil?
- (Of course that may not be true in general, but it is for all uses
- in the runtime, and we can play games with unsafe.)
-
-Optimizations (better compiler)
--------------------------------
-- Handle signed division overflow and sign extension earlier
-
-Regalloc
---------
-- Make less arch-dependent
-- Handle 2-address instructions
-- Make liveness analysis non-quadratic
-
-Future/other
-------------
-- Start another architecture (arm?)
-- 64-bit ops on 32-bit machines
-- Should we get rid of named types in favor of underlying types during SSA generation?
-- Infrastructure for enabling/disabling/configuring passes
-- Modify logging for at least pass=1, to be Warnl compatible

-// it using a greedy register allocator. Then all merge edges
-// (those targeting a block with len(Preds)>1) are processed to
-// shuffle data into the place that the target of the edge expects.
-//
-// The greedy allocator moves values into registers just before they
-// are used, spills registers only when necessary, and spills the
-// value whose next use is farthest in the future.
-//
-// The register allocator requires that a block is not scheduled until
-// at least one of its predecessors have been scheduled. The most recent
-// such predecessor provides the starting register state for a block.
-//
-// It also requires that there are no critical edges (critical =
-// comes from a block with >1 successor and goes to a block with >1
-// predecessor). This makes it easy to add fixup code on merge edges -
-// the source of a merge edge has only one successor, so we can add
-// fixup code to the end of that block.
-
-// Spilling
-//
-// For every value, we generate a spill immediately after the value itself.
-// x = Op y z : AX
-// x2 = StoreReg x
-// While AX still holds x, any uses of x will use that value. When AX is needed
-// for another value, we simply reuse AX. Spill code has already been generated
-// so there is no code generated at "spill" time. When x is referenced
-// subsequently, we issue a load to restore x to a register using x2 as
-// its argument:
-// x3 = Restore x2 : CX
-// x3 can then be used wherever x is referenced again.
-// If the spill (x2) is never used, it will be removed at the end of regalloc.
-//
-// Phi values are special, as always. We define two kinds of phis, those
-// where the merge happens in a register (a "register" phi) and those where
-// the merge happens in a stack location (a "stack" phi).
-//
-// A register phi must have the phi and all of its inputs allocated to the
-// same register. Register phis are spilled similarly to regular ops:
-// b1: y = ... : AX b2: z = ... : AX
-// goto b3 goto b3
-// b3: x = phi(y, z) : AX
-// x2 = StoreReg x
-//
-// A stack phi must have the phi and all of its inputs allocated to the same
-// stack location. Stack phis start out life already spilled - each phi
-// input must be a store (using StoreReg) at the end of the corresponding
-// predecessor block.
-// b1: y = ... : AX b2: z = ... : BX
-// y2 = StoreReg y z2 = StoreReg z
-// goto b3 goto b3
-// b3: x = phi(y2, z2)
-// The stack allocator knows that StoreReg args of stack-allocated phis
-// must be allocated to the same stack slot as the phi that uses them.
-// x is now a spilled value and a restore must appear before its first use.
-
-// TODO
-
-// Use an affinity graph to mark two values which should use the
-// same register. This affinity graph will be used to prefer certain
-// registers for allocation. This affinity helps eliminate moves that
-// are required for phi implementations and helps generate allocations
-// for 2-register architectures.
-
-// Note: regalloc generates a not-quite-SSA output. If we have:
-//
-// b1: x = ... : AX
-// x2 = StoreReg x
-// ... AX gets reused for something else ...
-// if ... goto b3 else b4
-//
-// b3: x3 = LoadReg x2 : BX b4: x4 = LoadReg x2 : CX
-// ... use x3 ... ... use x4 ...
-//
-// b2: ... use x3 ...
-//
-// If b3 is the primary predecessor of b2, then we use x3 in b2 and
-// add a x4:CX->BX copy at the end of b4.
-// But the definition of x3 doesn't dominate b2. We should really
-// insert a dummy phi at the start of b2 (x5=phi(x3,x4):BX) to keep
-// SSA form. For now, we ignore this problem as remaining in strict
-// SSA form isn't needed after regalloc. We'll just leave the use
-// of x3 not dominated by the definition of x3, and the CX->BX copy
-// will have no use (so don't run deadcode after regalloc!).
-// TODO: maybe we should introduce these extra phis?
-
-// Additional not-quite-SSA output occurs when spills are sunk out
-// of loops to the targets of exit edges from the loop. Before sinking,
-// there is one spill site (one StoreReg) targeting stack slot X, after
-// sinking there may be multiple spill sites targeting stack slot X,
-// with no phi functions at any join points reachable by the multiple
-// spill sites. In addition, uses of the spill from copies of the original
-// will not name the copy in their reference; instead they will name
-// the original, though both will have the same spill location. The
-// first sunk spill will be the original, but moved, to an exit block,
-// thus ensuring that there is a definition somewhere corresponding to
-// the original spill's uses.

-// The GC program encodes a sequence of 0 and 1 bits indicating scalar or pointer words in an object.
-// The encoding is a simple Lempel-Ziv program, with codes to emit literal bits and to repeat the
-// last n bits c times.
-//
-// The possible codes are:
-//
-// 00000000: stop
-// 0nnnnnnn: emit n bits copied from the next (n+7)/8 bytes, least significant bit first
-// 10000000 n c: repeat the previous n bits c times; n, c are varints
-// 1nnnnnnn c: repeat the previous n bits c times; c is a varint
-//
-// The numbers n and c, when they follow a code, are encoded as varints
-// using the same encoding as encoding/binary's Uvarint.

-
-// Writing of Go object files.
-//
-// Originally, Go object files were Plan 9 object files, but no longer.
-// Now they are more like standard object files, in that each symbol is defined
-// by an associated memory image (bytes) and a list of relocations to apply
-// during linking. We do not (yet?) use a standard file format, however.
-// For now, the format is chosen to be as simple as possible to read and write.
-// It may change for reasons of efficiency, or we may even switch to a
-// standard file format if there are compelling benefits to doing so.
-// See golang.org/s/go13linker for more background.
-//
-// The file format is:
-//
-// - magic header: "\x00\x00go17ld"
-// - byte 1 - version number
-// - sequence of strings giving dependencies (imported packages)
-// - empty string (marks end of sequence)
-// - sequence of symbol references used by the defined symbols
-// - byte 0xff (marks end of sequence)
-// - sequence of integer lengths:
-// - total data length
-// - total number of relocations
-// - total number of pcdata
-// - total number of automatics
-// - total number of funcdata
-// - total number of files
-// - data, the content of the defined symbols
-// - sequence of defined symbols
-// - byte 0xff (marks end of sequence)
-// - magic footer: "\xff\xffgo17ld"
-//
-// All integers are stored in a zigzag varint format.
-// See golang.org/s/go12symtab for a definition.
-//
-// Data blocks and strings are both stored as an integer
-// followed by that many bytes.
-//
-// A symbol reference is a string name followed by a version.
-//
-// A symbol points to other symbols using an index into the symbol
-// reference sequence. Index 0 corresponds to a nil LSym* pointer.
-// In the symbol layout described below "symref index" stands for this
-// index.
-//
-// Each symbol is laid out as the following fields (taken from LSym*):
-//
-// - byte 0xfe (sanity check for synchronization)
-// - type [int]
-// - name & version [symref index]
-// - flags [int]
-// 1<<0 dupok
-// 1<<1 local
-// 1<<2 add to typelink table
-// - size [int]
-// - gotype [symref index]
-// - p [data block]
-// - nr [int]
-// - r [nr relocations, sorted by off]
-//
-// If type == STEXT, there are a few more fields:
-//
-// - args [int]
-// - locals [int]
-// - nosplit [int]
-// - flags [int]
-// 1<<0 leaf
-// 1<<1 C function
-// 1<<2 function may call reflect.Type.Method
-// - nlocal [int]
-// - local [nlocal automatics]
-// - pcln [pcln table]
-//
-// Each relocation has the encoding:
-//
-// - off [int]
-// - siz [int]
-// - type [int]
-// - add [int]
-// - sym [symref index]
-//
-// Each local has the encoding:
-//
-// - asym [symref index]
-// - offset [int]
-// - type [int]
-// - gotype [symref index]
-//
-// The pcln table has the encoding:
-//
-// - pcsp [data block]
-// - pcfile [data block]
-// - pcline [data block]
-// - npcdata [int]
-// - pcdata [npcdata data blocks]
-// - nfuncdata [int]
-// - funcdata [nfuncdata symref index]
-// - funcdatasym [nfuncdata ints]
-// - nfile [int]
-// - file [nfile symref index]
-//
-// The file layout and meaning of type integers are architecture-independent.
-//
-// TODO(rsc): The file format is good for a first pass but needs work.
-// - There are SymID in the object file that should really just be strings.

-/*
- * You are doasm, holding in your hand a Prog* with p->as set to, say, ACRC32,
- * and p->from and p->to as operands (Addr*). The linker scans optab to find
- * the entry with the given p->as and then looks through the ytable for that
- * instruction (the second field in the optab struct) for a line whose first
- * two values match the Ytypes of the p->from and p->to operands. The function
- * oclass in span.c computes the specific Ytype of an operand and then the set
- * of more general Ytypes that it satisfies is implied by the ycover table, set
- * up in instinit. For example, oclass distinguishes the constants 0 and 1
- * from the more general 8-bit constants, but instinit says
- *
- * ycover[Yi0*Ymax + Ys32] = 1;
- * ycover[Yi1*Ymax + Ys32] = 1;
- * ycover[Yi8*Ymax + Ys32] = 1;
- *
- * which means that Yi0, Yi1, and Yi8 all count as Ys32 (signed 32)
- * if that's what an instruction can handle.
- *
- * In parallel with the scan through the ytable for the appropriate line, there
- * is a z pointer that starts out pointing at the strange magic byte list in
- * the Optab struct. With each step past a non-matching ytable line, z
- * advances by the 4th entry in the line. When a matching line is found, that
- * z pointer has the extra data to use in laying down the instruction bytes.
- * The actual bytes laid down are a function of the 3rd entry in the line (that
- * is, the Ztype) and the z bytes.
- *
- * For example, let's look at AADDL. The optab line says:
- * { AADDL, yaddl, Px, 0x83,(00),0x05,0x81,(00),0x01,0x03 },
- *
- * and yaddl says
- * uchar yaddl[] =
- * {
- * Yi8, Yml, Zibo_m, 2,
- * Yi32, Yax, Zil_, 1,
- * Yi32, Yml, Zilo_m, 2,
- * Yrl, Yml, Zr_m, 1,
- * Yml, Yrl, Zm_r, 1,
- * 0
- * };
- *
- * so there are 5 possible types of ADDL instruction that can be laid down, and
- * possible states used to lay them down (Ztype and z pointer, assuming z
- * points at {0x83,(00),0x05,0x81,(00),0x01,0x03}) are:
- *
- * Yi8, Yml -> Zibo_m, z (0x83, 00)
- * Yi32, Yax -> Zil_, z+2 (0x05)
- * Yi32, Yml -> Zilo_m, z+2+1 (0x81, 0x00)
- * Yrl, Yml -> Zr_m, z+2+1+2 (0x01)
- * Yml, Yrl -> Zm_r, z+2+1+2+1 (0x03)
- *
- * The Pconstant in the optab line controls the prefix bytes to emit. That's
- * relatively straightforward as this program goes.
- *
- * The switch on t[2] in doasm implements the various Z cases. Zibo_m, for
- * example, is an opcode byte (z[0]) then an asmando (which is some kind of
- * encoded addressing mode for the Yml arg), and then a single immediate byte.
- * Zilo_m is the same but a long (32-bit) immediate.

-/*
-Link, typically invoked as ``go tool link,'' reads the Go archive or object
-for a package main, along with its dependencies, and combines them
-into an executable binary.
-
-Command Line
-
-Usage:
-
- go tool link [flags] main.a
-
-Flags:
-
- -B note
- Add an ELF_NT_GNU_BUILD_ID note when using ELF.
- The value should start with 0x and be an even number of hex digits.
- -D address
- Set data segment address.
- -E entry
- Set entry symbol name.
- -H type
- Set executable format type.
- The default format is inferred from GOOS and GOARCH.
- On Windows, -H windowsgui writes a "GUI binary" instead of a "console binary."
- -I interpreter
- Set the ELF dynamic linker to use.
- -L dir1 -L dir2
- Search for imported packages in dir1, dir2, etc,
- after consulting $GOROOT/pkg/$GOOS_$GOARCH.
- -R quantum
- Set address rounding quantum.
- -T address
- Set text segment address.
- -V
- Print the linker version and exit.
- -X importpath.name=value
- Set the value of the string variable in importpath named name to value.
- Note that before Go 1.5 this option took two separate arguments.
- Now it takes one argument split on the first = sign.
- -buildmode mode
- Set build mode (default exe).
- -cpuprofile file
- Write CPU profile to file.
- -d
- Disable generation of dynamic executables.
- The emitted code is the same in either case; the option
- controls only whether a dynamic header is included.
- The dynamic header is on by default, even without any
- references to dynamic libraries, because many common
- system tools now assume the presence of the header.
- -extar ar
- Set the external archive program (default "ar").
- Used only for -buildmode=c-archive.
- -extld linker
- Set the external linker (default "clang" or "gcc").
- -extldflags flags
- Set space-separated flags to pass to the external linker.
- -f
- Ignore version mismatch in the linked archives.
- -g
- Disable Go package data checks.
- -installsuffix suffix
- Look for packages in $GOROOT/pkg/$GOOS_$GOARCH_suffix
- instead of $GOROOT/pkg/$GOOS_$GOARCH.
- -libgcc file
- Set name of compiler support library.
- This is only used in internal link mode.
- If not set, default value comes from running the compiler,
- which may be set by the -extld option.
- Set to "none" to use no support library.
- -linkmode mode
- Set link mode (internal, external, auto).
- This sets the linking mode as described in cmd/cgo/doc.go.
- -linkshared
- Link against installed Go shared libraries (experimental).
- -memprofile file
- Write memory profile to file.
- -memprofilerate rate
- Set runtime.MemProfileRate to rate.
- -msan
- Link with C/C++ memory sanitizer support.
- -o file
- Write output to file (default a.out, or a.out.exe on Windows).
- -pluginpath path
- The path name used to prefix exported plugin symbols.
- -r dir1:dir2:...
- Set the ELF dynamic linker search path.
- -race
- Link with race detection libraries.
- -s
- Omit the symbol table and debug information.
- -shared
- Generated shared object (implies -linkmode external; experimental).
- -tmpdir dir
- Write temporary files to dir.
- Temporary files are only used in external linking mode.
- -v
- Print trace of linker operations.
- -w
- Omit the DWARF symbol table.

-// deadcode marks all reachable symbols.
-//
-// The basis of the dead code elimination is a flood fill of symbols,

-//
-// This flood fill is wrapped in logic for pruning unused methods.
-// All methods are mentioned by relocations on their receiver's *rtype.
-// These relocations are specially defined as R_METHODOFF by the compiler
-// so we can detect and manipulated them here.
-//
-// There are three ways a method of a reachable type can be invoked:
-//
-// 1. direct call
-// 2. through a reachable interface type
-// 3. reflect.Value.Call, .Method, or reflect.Method.Func
-//
-// The first case is handled by the flood fill, a directly called method
-// is marked as reachable.
-//
-// The second case is handled by decomposing all reachable interface
-// types into method signatures. Each encountered method is compared
-// against the interface method signatures, if it matches it is marked
-// as reachable. This is extremely conservative, but easy and correct.
-//
-// The third case is handled by looking to see if any of:
-// - reflect.Value.Call is reachable
-// - reflect.Value.Method is reachable
-// - reflect.Type.Method or MethodByName is called.
-// If any of these happen, all bets are off and all exported methods
-// of reachable types are marked reachable.
-//
-// Any unreached text symbols are removed from ctxt.Textp.

-// Reading of Go object files.
-//
-// Originally, Go object files were Plan 9 object files, but no longer.
-// Now they are more like standard object files, in that each symbol is defined
-// by an associated memory image (bytes) and a list of relocations to apply
-// during linking. We do not (yet?) use a standard file format, however.
-// For now, the format is chosen to be as simple as possible to read and write.
-// It may change for reasons of efficiency, or we may even switch to a
-// standard file format if there are compelling benefits to doing so.
-// See golang.org/s/go13linker for more background.
-//
-// The file format is:
-//
-// - magic header: "\x00\x00go17ld"
-// - byte 1 - version number
-// - sequence of strings giving dependencies (imported packages)
-// - empty string (marks end of sequence)
-// - sequence of symbol references used by the defined symbols
-// - byte 0xff (marks end of sequence)
-// - sequence of integer lengths:
-// - total data length
-// - total number of relocations
-// - total number of pcdata
-// - total number of automatics
-// - total number of funcdata
-// - total number of files
-// - data, the content of the defined symbols
-// - sequence of defined symbols
-// - byte 0xff (marks end of sequence)
-// - magic footer: "\xff\xffgo17ld"
-//
-// All integers are stored in a zigzag varint format.
-// See golang.org/s/go12symtab for a definition.
-//
-// Data blocks and strings are both stored as an integer
-// followed by that many bytes.
-//
-// A symbol reference is a string name followed by a version.
-//
-// A symbol points to other symbols using an index into the symbol
-// reference sequence. Index 0 corresponds to a nil Object* pointer.
-// In the symbol layout described below "symref index" stands for this
-// index.
-//
-// Each symbol is laid out as the following fields (taken from Object*):
-//
-// - byte 0xfe (sanity check for synchronization)
-// - type [int]
-// - name & version [symref index]
-// - flags [int]
-// 1<<0 dupok
-// 1<<1 local
-// 1<<2 add to typelink table
-// - size [int]
-// - gotype [symref index]
-// - p [data block]
-// - nr [int]
-// - r [nr relocations, sorted by off]
-//
-// If type == STEXT, there are a few more fields:
-//
-// - args [int]
-// - locals [int]
-// - nosplit [int]
-// - flags [int]
-// 1<<0 leaf
-// 1<<1 C function
-// 1<<2 function may call reflect.Type.Method
-// - nlocal [int]
-// - local [nlocal automatics]
-// - pcln [pcln table]
-//
-// Each relocation has the encoding:
-//
-// - off [int]
-// - siz [int]
-// - type [int]
-// - add [int]
-// - sym [symref index]
-//
-// Each local has the encoding:
-//
-// - asym [symref index]
-// - offset [int]
-// - type [int]
-// - gotype [symref index]
-//
-// The pcln table has the encoding:
-//
-// - pcsp [data block]
-// - pcfile [data block]
-// - pcline [data block]
-// - npcdata [int]
-// - pcdata [npcdata data blocks]
-// - nfuncdata [int]
-// - funcdata [nfuncdata symref index]
-// - funcdatasym [nfuncdata ints]
-// - nfile [int]
-// - file [nfile symref index]
-//
-// The file layout and meaning of type integers are architecture-independent.
-//
-// TODO(rsc): The file format is good for a first pass but needs work.
-// - There are SymID in the object file that should really just be strings.

- // architectures, but is laid out quite differently. When we
- // see an R_PPC64_REL24 relocation to a dynamic symbol
- // (indicating that the call needs to go through the PLT), we
- // generate up to three stubs and reserve a PLT slot.
- //
- // 1) The call site will be bl x; nop (where the relocation
- // applies to the bl). We rewrite this to bl x_stub; ld
- // r2,24(r1). The ld is necessary because x_stub will save
- // r2 (the TOC pointer) at 24(r1) (the "TOC save slot").
- //
- // 2) We reserve space for a pointer in the .plt section (once
- // per referenced dynamic function). .plt is a data
- // section filled solely by the dynamic linker (more like
- // .plt.got on other architectures). Initially, the
- // dynamic linker will fill each slot with a pointer to the
- // corresponding x@plt entry point.
- //
- // 3) We generate the "call stub" x_stub (once per dynamic
- // function/object file pair). This saves the TOC in the
- // TOC save slot, reads the function pointer from x's .plt
- // slot and calls it like any other global entry point
- // (including setting r12 to the function address).
- //
- // 4) We generate the "symbol resolver stub" x@plt (once per
- // dynamic function). This is solely a branch to the glink
- // resolver stub.
- //
- // 5) We generate the glink resolver stub (only once). This
- // computes which symbol resolver stub we came through and
- // invokes the dynamic resolver via a pointer provided by
- // the dynamic linker. This will patch up the .plt slot to
- // point directly at the function so future calls go
- // straight from the call stub to the real function, and
- // then call the function.
-
- // NOTE: It's possible we could make ppc64 closer to other
- // architectures: ppc64's .plt is like .plt.got on other
- // platforms and ppc64's .glink is like .plt on other
- // platforms.
-
- // Find all R_PPC64_REL24 relocations that reference dynamic
- // imports. Reserve PLT entries for these symbols and
- // generate call stubs. The call stubs need to live in .text,

-var AuthorPaidByTheColumnInch struct {
- fog int `
- London. Michaelmas term lately over, and the Lord Chancellor sitting in Lincoln’s Inn Hall. Implacable November weather. As much mud in the streets as if the waters had but newly retired from the face of the earth, and it would not be wonderful to meet a Megalosaurus, forty feet long or so, waddling like an elephantine lizard up Holborn Hill. Smoke lowering down from chimney-pots, making a soft black drizzle, with flakes of soot in it as big as full-grown snowflakes—gone into mourning, one might imagine, for the death of the sun. Dogs, undistinguishable in mire. Horses, scarcely better; splashed to their very blinkers. Foot passengers, jostling one another’s umbrellas in a general infection of ill temper, and losing their foot-hold at street-corners, where tens of thousands of other foot passengers have been slipping and sliding since the day broke (if this day ever broke), adding new deposits to the crust upon crust of mud, sticking at those points tenaciously to the pavement, and accumulating at compound interest.
-
- Fog everywhere. Fog up the river, where it flows among green aits and meadows; fog down the river, where it rolls defiled among the tiers of shipping and the waterside pollutions of a great (and dirty) city. Fog on the Essex marshes, fog on the Kentish heights. Fog creeping into the cabooses of collier-brigs; fog lying out on the yards and hovering in the rigging of great ships; fog drooping on the gunwales of barges and small boats. Fog in the eyes and throats of ancient Greenwich pensioners, wheezing by the firesides of their wards; fog in the stem and bowl of the afternoon pipe of the wrathful skipper, down in his close cabin; fog cruelly pinching the toes and fingers of his shivering little ‘prentice boy on deck. Chance people on the bridges peeping over the parapets into a nether sky of fog, with fog all round them, as if they were up in a balloon and hanging in the misty clouds.
-
- Gas looming through the fog in divers places in the streets, much as the sun may, from the spongey fields, be seen to loom by husbandman and ploughboy. Most of the shops lighted two hours before their time—as the gas seems to know, for it has a haggard and unwilling look.
-
- The raw afternoon is rawest, and the dense fog is densest, and the muddy streets are muddiest near that leaden-headed old obstruction, appropriate ornament for the threshold of a leaden-headed old corporation, Temple Bar. And hard by Temple Bar, in Lincoln’s Inn Hall, at the very heart of the fog, sits the Lord High Chancellor in his High Court of Chancery.`
-
- wind int `
- It was grand to see how the wind awoke, and bent the trees, and drove the rain before it like a cloud of smoke; and to hear the solemn thunder, and to see the lightning; and while thinking with awe of the tremendous powers by which our little lives are encompassed, to consider how beneficent they are, and how upon the smallest flower and leaf there was already a freshness poured from all this seeming rage, which seemed to make creation new again.`
-
- jarndyce int `
- Jarndyce and Jarndyce drones on. This scarecrow of a suit has, over the course of time, become so complicated, that no man alive knows what it means. The parties to it understand it least; but it has been observed that no two Chancery lawyers can talk about it for five minutes, without coming to a total disagreement as to all the premises. Innumerable children have been born into the cause; innumerable young people have married into it; innumerable old people have died out of it. Scores of persons have deliriously found themselves made parties in Jarndyce and Jarndyce, without knowing how or why; whole families have inherited legendary hatreds with the suit. The little plaintiff or defendant, who was promised a new rocking-horse when Jarndyce and Jarndyce should be settled, has grown up, possessed himself of a real horse, and trotted away into the other world. Fair wards of court have faded into mothers and grandmothers; a long procession of Chancellors has come in and gone out; the legion of bills in the suit have been transformed into mere bills of mortality; there are not three Jarndyces left upon the earth perhaps, since old Tom Jarndyce in despair blew his brains out at a coffee-house in Chancery Lane; but Jarndyce and Jarndyce still drags its dreary length before the Court, perennially hopeless.`
-
- principle int `
- The one great principle of the English law is, to make business for itself. There is no other principle distinctly, certainly, and consistently maintained through all its narrow turnings. Viewed by this light it becomes a coherent scheme, and not the monstrous maze the laity are apt to think it. Let them but once clearly perceive that its grand principle is to make business for itself at their expense, and surely they will cease to grumble.`

-Package big implements arbitrary-precision arithmetic (big numbers).
-The following numeric types are supported:
-
- Int signed integers
- Rat rational numbers
- Float floating-point numbers
-
-The zero value for an Int, Rat, or Float correspond to 0. Thus, new
-values can be declared in the usual ways and denote 0 without further
-initialization:
-
- var x Int // &x is an *Int of value 0
- var r = &Rat{} // r is a *Rat of value 0
- y := new(Float) // y is a *Float of value 0
-
-Alternatively, new values can be allocated and initialized with factory
-functions of the form:
-
- func NewT(v V) *T
-
-For instance, NewInt(x) returns an *Int set to the value of the int64
-argument x, NewRat(a, b) returns a *Rat set to the fraction a/b where
-a and b are int64 values, and NewFloat(f) returns a *Float initialized
-to the float64 argument f. More flexibility is provided with explicit
-setters, for instance:
-
- var z1 Int
- z1.SetUint64(123) // z1 := 123
- z2 := new(Rat).SetFloat64(1.25) // z2 := 5/4
- z3 := new(Float).SetInt(z1) // z3 := 123.0
-
-Setters, numeric operations and predicates are represented as methods of
-the form:
-
- func (z *T) SetV(v V) *T // z = v
- func (z *T) Unary(x *T) *T // z = unary x
- func (z *T) Binary(x, y *T) *T // z = x binary y
- func (x *T) Pred() P // p = pred(x)
-
-with T one of Int, Rat, or Float. For unary and binary operations, the
-result is the receiver (usually named z in that case; see below); if it
-is one of the operands x or y it may be safely overwritten (and its memory
-reused).
-
-Arithmetic expressions are typically written as a sequence of individual
-method calls, with each call corresponding to an operation. The receiver
-denotes the result and the method arguments are the operation's operands.
-For instance, given three *Int values a, b and c, the invocation
-
- c.Add(a, b)
-
-computes the sum a + b and stores the result in c, overwriting whatever
-value was held in c before. Unless specified otherwise, operations permit
-aliasing of parameters, so it is perfectly ok to write
-
- sum.Add(sum, x)
-
-to accumulate values x in a sum.
-
-(By always passing in a result value via the receiver, memory use can be
-much better controlled. Instead of having to allocate new memory for each
-result, an operation can reuse the space allocated for the result value,
-and overwrite that value with the new result in the process.)
-
-Notational convention: Incoming method parameters (including the receiver)
-are named consistently in the API to clarify their use. Incoming operands
-are usually named x, y, a, b, and so on, but never z. A parameter specifying
-the result is named z (typically the receiver).
-
-For instance, the arguments for (*Int).Add are named x and y, and because
-the receiver specifies the result destination, it is called z:
-
- func (z *Int) Add(x, y *Int) *Int
-
-Methods of this form typically return the incoming receiver as well, to
-enable simple call chaining.
-
-Methods which don't require a result value to be passed in (for instance,
-Int.Sign), simply return the result. In this case, the receiver is typically
-the first operand, named x:
-
- func (x *Int) Sign() int
-
-Various methods support conversions between strings and corresponding
-numeric values, and vice versa: *Int, *Rat, and *Float values implement
-the Stringer interface for a (default) string representation of the value,
-but also provide SetString methods to initialize a value from a string in
-a variety of supported formats (see the respective SetString documentation).
-
-Finally, *Int, *Rat, and *Float satisfy the fmt package's Scanner interface
-for scanning and (except for *Rat) the Formatter interface for formatted
-printing.
