[LLVMdev] X86 disassembler & assembler mismatch
hi,
some instructions mismatch between assembler & disassembler, like below.
it seems this happens with all SSECC related instructions?
thanks,
Jun
$ echo "cmpps xmm1, xmm2, 23" | ./Release+Asserts/bin/llvm-mc -assemble
-triple=x86_64 --output-asm-variant=1 -x86-asm-syntax=intel -show-encoding

cmpps xmm1, xmm2, 23 # encoding: [0x0f,0xc2,0xca,0x17]
