Hi,
I am trying to assemble below instruction with latest LLVM code, but fail.
Am I doing something wrong, or is this a bug?
$ echo "vaddps zmm7 {k6}, zmm2, zmm4,
{rd-sae}"|./Release+Asserts/bin/llvm-mc -assemble -triple=x86_64 -mcpu=knl
-show-encoding -x86-asm-syntax=intel
.text
<stdin>:1:31: error: unknown token in expression
vaddps zmm7 {k6}, zmm2, zmm4, {rd-sae}
^
<stdin>:1:31: error: unknown token in expression
vaddps zmm7 {k6}, zmm2, zmm4, {rd-sae}
Thanks,
Jun

(I think the ^ is misplaced; it should point to the {rd-sae}.) (I may be wrong here but looks like even the X86AsmParser is lacking support for sae even though some instruction in the .td file contain {sae} in their asm syntax.)
