Summary: scalar_to_vector not selecting on x86 (-mcpu=core2) for
v2f32
Product: libraries
Version: trunk
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: Backend: X86
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]

Consider the following test case:
define void @entry(i32 %m_task_id, i32 %start_x, i32 %end_x) {
; <label>:0
br i1 false, label %bb.nph, label %._crit_edge
bb.nph: ; preds = %bb.nph, %0
%t2206f2.0 = phi <2 x float> [ %2, %bb.nph ], [ undef, %0 ]
; <<2 x float>> [#uses=1]
insertelement <2 x float> %t2206f2.0, float 0.000000e+00, i32 0
; <<2 x float>>:1 [#uses=1]
insertelement <2 x float> %1, float 0.000000e+00, i32 1 ; <<2 x
float>>:2 [#uses=1]
br label %bb.nph
._crit_edge: ; preds = %0
ret void
}
Running llc -mcpu=core2 on this produces:
Cannot yet select: 0x8b0471c: v2f32 = scalar_to_vector 0x8b049c4
This is a regression since 2.3.
