Recently I committed a patch solving
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88560
The patch resulted in test vsx-simode2.c failure. Here is the
difference in generated code:
@@ -13,9 +13,8 @@ foo:
.LFB0:
.cfi_startproc
std 3,-16(1)
- ori 2,2,0
- lwz 9,-12(1)
- mtvsrwz 32,9
+ addi 9,1,-12
+ lxsiwzx 32,0,9
The new version is one insn less. So I propose the following patch
changing the expected code generation.
Is it ok to commit it?
