We consider both x86, x86-64 and x32 (32bit mode x86-64), although 26 * we currently only target x86. The ABI has different conventions and we hope to have a single 27 * convention to simplify code generation. Changing something that is callee save and making it 28 * caller save places a burden on up-calls to save/restore the callee save register, however, there 29 * are few registers that are callee save in the ABI. Changing something that is caller save and 30 * making it callee save places a burden on down-calls to save/restore the callee save register. 31 * For these reasons we aim to match native conventions for caller and callee save. The first 4 32 * registers can be used for byte operations, for this reason they are preferred for temporary 33 * scratch registers. 34 * 35 * General Purpose Register: 36 * Native: x86 | x86-64 / x32 | ART 37 * r0/eax: caller save | caller save | caller, Method*, scratch, return value 38 * r1/ecx: caller save | caller save, arg4 | caller, arg1, scratch 39 * r2/edx: caller save | caller save, arg3 | caller, arg2, scratch, high half of long return 40 * r3/ebx: callEE save | callEE save | callER, arg3, scratch 41 * r4/esp: stack pointer 42 * r5/ebp: callee save | callee save | callee, available for dalvik register promotion 43 * r6/esi: callEE save | callER save, arg2 | callee, available for dalvik register promotion 44 * r7/edi: callEE save | callER save, arg1 | callee, available for dalvik register promotion 45 * --- x86-64/x32 registers 46 * Native: x86-64 / x32 | ART 47 * r8: caller save, arg5 | caller, scratch 48 * r9: caller save, arg6 | caller, scratch 49 * r10: caller save | caller, scratch 50 * r11: caller save | caller, scratch 51 * r12: callee save | callee, available for dalvik register promotion 52 * r13: callee save | callee, available for dalvik register promotion 53 * r14: callee save | callee, available for dalvik register promotion 54 * r15: callee save | callee, available for dalvik register promotion 55 * 56 * There is no rSELF, instead on x86 fs: has a base address of Thread::Current, whereas on 57 * x86-64/x32 gs: holds it. 58 * 59 * For floating point we don't support CPUs without SSE2 support (ie newer than PIII): 60 * Native: x86 | x86-64 / x32 | ART 61 * XMM0: caller save |caller save, arg1 | caller, float/double return value (except for native x86 code) 62 * XMM1: caller save |caller save, arg2 | caller, scratch 63 * XMM2: caller save |caller save, arg3 | caller, scratch 64 * XMM3: caller save |caller save, arg4 | caller, scratch 65 * XMM4: caller save |caller save, arg5 | caller, scratch 66 * XMM5: caller save |caller save, arg6 | caller, scratch 67 * XMM6: caller save |caller save, arg7 | caller, scratch 68 * XMM7: caller save |caller save, arg8 | caller, scratch 69 * --- x86-64/x32 registers 70 * XMM8 .. 15: caller save 71 * 72 * X87 is a necessary evil outside of ART code: 73 * ST0: x86 float/double native return value, caller save 74 * ST1 ..
