[LLVMdev] Adding xadd instruction to X86
...lowing entry to X86InstrInfo.td:
def XADD32mr : I<0x87, MRMDestMem,
(ops i32mem:$src1, R32:$src2),
"xadd{l} {$src1|$src2}, {$src2|$src1}">;
The xadd is emitted for the intrinsic function:
call int (<integer type>*, <integer type>)*
%llvm.atomic_fetch_add_store(<integer type>* <pointer>,
<integer type> <value>)
I currently have the following code (PtrReg contains the
pointer argument, ValReg the value arg, and TmpReg an unused
register.):
