Bug ID: 42585
Summary: SROA assert fails VTy == CandidateTys[0] && "Different
vector types with the same element type!
Product: new-bugs
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: new bugs
Assignee: unassignedb...@nondot.org
Reporter: felipe.de.azevedo.piove...@intel.com

The following IR causes SROA to assert a failure. Verified this on a trunk
build with asserts on.
opt test.ll -sroa
target datalayout =
"e-p:64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:32:64-f32:32:32-f64:64:64-v64:64:64-v128:128:128-a0:0:64-n8:16:32:64"
define <4 x i1> @vector_bitcast() {
; CHECK-LABEL: @vector_bitcast
%a = alloca <3 x i1>
store <3 x i1> <i1 1,i1 0,i1 1>, <3 x i1>* %a
%cast = bitcast <3 x i1>* %a to <4 x i1>*
%vec = load <4 x i1>, <4 x i1>* %cast
ret <4 x i1> %vec
}
