Hello,
Just found that the 3DNow! instruction pmulhrw is decoded as 'pfmulhrw' in
objdump -d. While it's an 3DNow! instruction, pmulhrw actually is an SIMD
integer instruction and both the AMD official documents and gcc
builtin/intrinsics refer to pmulhrw instead of pfmulhrw. Is this a known
problem?
objdump version is:
GNU objdump 2.17.50 20060824
