Bug ID: 18631
Summary: avx512: wrong memory size for vcvtt?ps2u?qq
instructions with data broadcast
Product: binutils
Version: 2.26 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: [email protected]
Target Milestone: ---
The vcvtps2qq, vcvtps2uqq, vcvttps2qq, and vcvttps2uqq instructions are
incorrectly defined regarding the memory operand size with data broadcast for
avx512. Simple example (with git master):
==========
$ cat vcvtps2qq.s
.text
vcvtps2qq (%rax){1to8}, %zmm0
$ as-new -o vcvtps2qq.o vcvtps2qq.s
$ objdump -Mintel -d vcvtps2qq.o
vcvtps2qq.o: file format elf64-x86-64
Disassembly of section .text:
0000000000000000 <.text>:
0: 62 f1 7d 58 7b 00 vcvtps2qq zmm0,YMMWORD PTR [rax]{1to8}
==========
It should be:
vcvtps2qq zmm0,DWORD PTR [rax]{1to8}
