+These two functions should compile to identical code on x86-32:
+
+define <2 x i64> @test2(i64 %arg) {
+entry:
+ %A = and i64 %arg, 1234567
+ %B = insertelement <2 x i64> undef, i64 %A, i32 0
+ ret <2 x i64> %B
+}
+
+define <2 x i64> @test2(i64 %arg) {
+entry:
+ %A = and i64 %arg, 1234567
+ %B = insertelement <2 x i64> zeroinitializer, i64 %A, i32 0
+ ret <2 x i64> %B
+}
+
+The later compiles to:
+
+_test2:
+ movl $1234567, %eax
+ andl 4(%esp), %eax
+ movd %eax, %xmm0
+ ret
+
+the former compiles to:
+
+_test2:
+ subl $28, %esp
+ movl $1234567, %eax
+ andl 32(%esp), %eax
+ movl %eax, (%esp)
+ movl $0, 4(%esp)
+ movaps (%esp), %xmm0
+ addl $28, %esp
+ ret
