* Runtime register usage conventions.
*
* r0-r3: Argument registers in both Dalvik and C/C++ conventions.
* However, for Dalvik->Dalvik calls we'll pass the target's Method*
* pointer in r0 as a hidden arg0. Otherwise used as codegen scratch
* registers.
* r0-r1: As in C/C++ r0 is 32-bit return register and r0/r1 is 64-bit
* r4 : (rARM_SUSPEND) is reserved (suspend check/debugger assist)
* r5 : Callee save (promotion target)
* r6 : Callee save (promotion target)
* r7 : Callee save (promotion target)
* r8 : Callee save (promotion target)
* r9 : (rARM_SELF) is reserved (pointer to thread-local storage)
* r10 : Callee save (promotion target)
* r11 : Callee save (promotion target)
* r12 : Scratch, may be trashed by linkage stubs
* r13 : (sp) is reserved
* r14 : (lr) is reserved
* r15 : (pc) is reserved
*
* 5 core temps that codegen can use (r0, r1, r2, r3, r12)
* 7 core registers that can be used for promotion
*
* Floating pointer registers
* s0-s31
* d0-d15, where d0={s0,s1}, d1={s2,s3}, ... , d15={s30,s31}
*
* s16-s31 (d8-d15) preserved across C calls
* s0-s15 (d0-d7) trashed across C calls
*
* s0-s15/d0-d7 used as codegen temp/scratch
* s16-s31/d8-d31 can be used for promotion.
*
* Calling convention
* o On a call to a Dalvik method, pass target's Method* in r0
* o r1-r3 will be used for up to the first 3 words of arguments
* o Arguments past the first 3 words will be placed in appropriate
* out slots by the caller.
* o If a 64-bit argument would span the register/memory argument
* boundary, it will instead be fully passed in the frame.
* o Maintain a 16-byte stack alignment
*
* Stack frame diagram (stack grows down, higher addresses at top):
*
* +------------------------+
* | IN[ins-1] | {Note: resides in caller's frame}
* | . |
* | IN[0] |
* | caller's Method* |
* +========================+ {Note: start of callee's frame}
* | spill region | {variable sized - will include lr if non-leaf.}
* +------------------------+
* | ...filler word... | {Note: used as 2nd word of V[locals-1] if long]
* +------------------------+
* | V[locals-1] |
* | V[locals-2] |
* | . |
* | . |
* | V[1] |
* | V[0] |
* +------------------------+
* | 0 to 3 words padding |
* +------------------------+
* | OUT[outs-1] |
* | OUT[outs-2] |
* | . |
* | OUT[0] |
* | cur_method* | <<== sp w/ 16-byte alignment
