Summary: [AVX] llvm-objdump incorrectly prints vmovmskps as
movmskps

bitcode file
Given the attached object file (which corresponds to the attached LLVM assembly
file run through llc -mattr=+avx x.ll -filetype=obj -o x.o), when the object
file is run through llvm-objdump, the following output is printed:
% llvm-objdump x.o -disassemble
x.o: file format Mach-O 64-bit x86-64
Disassembly of section __TEXT,__text:
_foo:
0: c5 fc 50 c0 movmskps
%xmm0, %eax
4: c3 ret
%
I believe that should be a 'vmovmskps', with %ymm0, not %xmm0. (Note that as
far as I can tell, the object file generated by llc has the proper encoding for
a vmovmskps instruction, so the issue doesn't seem to be that it's being
mis-encoded.)
