Bug ID: 43630
Summary: [X86] Second k-register result of vp2intersect does
not get added to clobber list for ms style inline
assembly
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: X86
Assignee: [email protected]

The vp2intersect instruction writes 2 consecutive k-registers. But only one is
listed in the assembly string. The clobber list is inferred from the parsed
operands list, but only the one operand will be present there.
Example test
void t1() {
__asm vp2intersectq k0, xmm0, xmm1
}
Produces
tail call void asm sideeffect inteldialect "vp2intersectq k0, xmm0, xmm1",
"~{k0},~{dirflag},~{fpsr},~{flags}"(
