Bug ID: 3392350
Summary: AVX rounding mode is not printed in disassembly
Product: NASM
Version: 2.12.xx
Hardware: All
OS: All
Status: OPEN
Severity: normal
Priority: Medium
Component: Assembler
Assignee: nobody at nasm.us
Reporter: b7.10110111 at gmail.com
CC: gorcunov at gmail.com, hpa at zytor.com, nasm-bugs at nasm.us
The following bash command reproduces this problem for me:
xxd -g1 -r <<< '0 62 F1 74 DD 59 FC' | ndisasm -o 0 -b 32 /dev/stdin
I get this output:
00000000 62F174DD59FC vmulps xmm7{k5}{z},xmm1,xmm4
This instruction was compiled by nasm from
vmulps zmm7{k5}{z},zmm1,zmm4,{ru-sae}
And objdump also sees it in this way.
