(In reply to comment #1)
 PR 10469 looks like a testcase where this could improve the code generation.\

gcc.dg/vect/vect-25.c is a testcase too.

This is what is currently generated (the invariant is in r3):

mr r9,r3
mr r10,r3
mr r11,r3
mr r12,r3 
L6:
addi r7,r1,1104
stw r9,0(r7)
stw r10,4(r7)
stw r11,8(r7)
stw r12,12(r7)
lvx v0,0,r7
stvx v0,0,r2
addi r2,r2,16
bdnz L6

instead of:

stw r3,0(r2)
lvewx v0,0,r2
vspltw v0,v0,0
L4:
stvx v0,r2,r0
addi r2,r2,16
bdnz L4
