Bug ID: 32544
Summary: [2.44 regression] "Unsupported broadcast" assemble
failure for vpsubd
Product: binutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: sam at gentoo dot org
Target Milestone: ---
This fails with recent gas:
```
.file "a.c"
.text
.section .text.startup,"ax",@progbits
.p2align 4
.globl main
.type main, @function
main:
.LFB0:
.cfi_startproc
#APP
# 2 "/tmp/a.c" 1
vpsubd -168(%ebp){1to4}, %xmm0, %xmm0
# 0 "" 2
#NO_APP
xorl %eax, %eax
ret
.cfi_endproc

```
I originally filed it as a GCC bug but it is a gas regression, I think. 2.43
gas works.
