--- Comment #4 from seurer at gcc dot gnu.org ---
The fix for pr92529 does not fix these.
What changed is some of the instructions generated. For example, in
gcc.target/powerpc/ppc-round.c
round_double_uint:
.LFB2:
.cfi_startproc
fctiwuz 1,1
addi 9,1,-16
stfiwx 1,0,9
ori 2,2,0
lfiwzx 1,0,9
fcfid 1,1
blr
became
round_double_uint:
.LFB5:
.cfi_startproc
fctiwz 1,1
addi 9,1,-16
stfiwx 1,0,9
ori 2,2,0
lfiwax 1,0,9
fcfid 1,1
blr
They both apparently work (albeit aren't close to optimal). So I think the
solution here is to update the expected instruction counts and maybe make a
TODO somewhere to see if the generated code could be made better.
