--- Comment #3 from Segher Boessenkool <segher at gcc dot gnu.org> ---
After the fix for PR66217, this now is
foo:
rldicl 4,4,0,32
blr
bar:
0: addis 2,12,.TOC.-0b@ha
addi 2,2,.TOC.-0b@l
.localentry bar,.-bar
mflr 0
std 0,16(1)
stdu 1,-64(1)
bl foo
addi 1,1,64
ld 0,16(1)
rldicl 4,4,0,32
mtlr 0
blr
which is sort of optimal (you could argue that the do-not-care parts of r4 do
not need to be cleared, after which it can tail-call).
I'm closing the bug.
