+/* These are bit masks and shift counts to use to access the various
+ fields of an instruction. To retrieve the X field of an
+ instruction, use the expression
+ (i >> OP_SH_X) & OP_MASK_X
+ To set the same field (to j), use
+ i = (i &~ (OP_MASK_X << OP_SH_X)) | (j << OP_SH_X)
+
+ Make sure you use fields that are appropriate for the instruction,
+ of course.
+
+ The 'i' format uses OP, RS, RT and IMMEDIATE.
+
+ The 'j' format uses OP and TARGET.
+
+ The 'r' format uses OP, RS, RT, RD, SHAMT and FUNCT.
+
+ The 'b' format uses OP, RS, RT and DELTA.
+
+ The floating point 'i' format uses OP, RS, RT and IMMEDIATE.
+
+ The floating point 'r' format uses OP, FMT, FT, FS, FD and FUNCT.
+
+ A breakpoint instruction uses OP, CODE and SPEC (10 bits of the
+ breakpoint instruction are not defined; Kane says the breakpoint
+ code field in BREAK is 20 bits; yet MIPS assemblers and debuggers
+ only use ten bits). An optional two-operand form of break/sdbbp
+ allows the lower ten bits to be set too, and MIPS32 and later
+ architectures allow 20 bits to be set with a signal operand
+ (using CODE20).
+
+ The syscall instruction uses CODE20.
+
+ The general coprocessor instructions use COPZ. */

+/* MIPS DSP ASE support.
+ NOTE:
+ 1. MIPS DSP ASE includes 4 accumulators ($ac0 - $ac3). $ac0 is the pair
+ of original HI and LO. $ac1, $ac2 and $ac3 are new registers, and have
+ the same structure as $ac0 (HI + LO). For DSP instructions that write or
+ read accumulators (that may be $ac0), we add WR_a (WR_HILO) or RD_a
+ (RD_HILO) attributes, such that HILO dependencies are maintained
+ conservatively.
+
+ 2. For some mul. instructions that use integer registers as destinations
+ but destroy HI+LO as side-effect, we add WR_HILO to their attributes.
+
+ 3. MIPS DSP ASE includes a new DSP control register, which has 6 fields
+ (ccond, outflag, EFI, c, scount, pos). Many DSP instructions read or write
+ certain fields of the DSP control register. For simplicity, we decide not
+ to track dependencies of these fields.
+ However, "bposge32" is a branch instruction that depends on the "pos"
+ field. In order to make sure that GAS does not reorder DSP instructions
+ that writes the "pos" field and "bposge32", we add DSP_VOLA (INSN_TRAP)
+ attribute to those instructions that write the "pos" field. */

+Unsolved issues/bugs in the mips/mipsel backend
+-----------------------------------------------
+
+General
+-------
+- Unimplemented ASEs:
+ - MIPS16
+ - MDMX
+ - SmartMIPS
+ - DSP r1
+ - DSP r2
+- MT ASE only partially implemented and not functional
+- Shadow register support only partially implemented,
+ lacks set switching on interrupt/exception.
+- 34K ITC not implemented.
+- A general lack of documentation, especially for technical internals.
+ Existing documentation is x86-centric.
+- Reverse endianness bit not implemented
+- The TLB emulation is very inefficient:
+ Qemu's softmmu implements a x86-style MMU, with separate entries
+ for read/write/execute, a TLB index which is just a modulo of the
+ virtual address, and a set of TLBs for each user/kernel/supervisor
+ MMU mode.
+ MIPS has a single entry for read/write/execute and only one MMU mode.
+ But it is fully associative with randomized entry indices, and uses
+ up to 256 ASID tags as additional matching criterion (which roughly
+ equates to 256 MMU modes). It also has a global flag which causes
+ entries to match regardless of ASID.
+ To cope with these differences, Qemu currently flushes the TLB at
+ each ASID change. Using the MMU modes to implement ASIDs hinges on
+ implementing the global bit efficiently.
+- save/restore of the CPU state is not implemented (see machine.c).
+
+MIPS64
+------
+- Userland emulation (both n32 and n64) not functional.
+
+"Generic" 4Kc system emulation
+------------------------------
+- Doesn't correspond to any real hardware. Should be removed some day,
+ U-Boot is the last remaining user.
+
+PICA 61 system emulation
+------------------------
+- No framebuffer support yet.
+
+MALTA system emulation
+----------------------
+- We fake firmware support instead of doing the real thing
+- Real firmware (YAMON) falls over when trying to init RAM, presumably
+ due to lacking system controller emulation.
+- Bonito system controller not implemented
+- MSC1 system controller not implemented
