Hello!
Can someone please tell me if is there an API (or some other way) to query MCInstrDesc to find out the type of its memory operands?
As an example, consider the following description of MOV32mr (from X86InstrInfo.td)
def MOV32mr : I<0x89, MRMDestMem, (outs), (ins i32mem:$dst, GR32:$src),
“mov{l}\t{$src, $dst|$dst, $src}”,
[(store GR32:$src, addr:$dst)], IIC_MOV_MEM>, OpSize32;
or that of MOVSX64rm (from X86InstrExtension.td)
def MOVSX64rm32: RI<0x63, MRMSrcMem, (outs GR64:$dst), (ins i32mem:$src),
“movs{lq|xd}\t{$src, $dst|$dst, $src}”,
[(set GR64:$dst, (sextloadi64i32 addr:$src))], IIC_MOVSX>,
Sched<[WriteALULd]>, Requires<[In64BitMode]>;
Given an MCInstrDesc object, I’d like to know of a way to find out the type of ‘ins’ operand i32mem.
I am particularly interested in figuring out the type of a memory operand of a given MCInstrDesc, if one exists.
Thanks for any help,
