Fix a significant code quality regression I introduced on PPC64 quite
a while ago. We now produce:
_foo:
mflr r0
std r0, 16(r1)
ld r2, 16(r1)
std r2, 0(r3)
ld r0, 16(r1)
mtlr r0
blr
instead of:
_foo:
mflr r0
std r0, 16(r1)
lis r0, 0
ori r0, r0, 16
ldx r2, r1, r0
std r2, 0(r3)
ld r0, 16(r1)
mtlr r0
blr
for:
void foo(void **X) {
*X = __builtin_return_address(0);
}
on ppc64.
