Comment 1 Segher Boessenkool 2024-03-28 23:09:25 UTC 
It fails with -m32 only for me?

make  -k check-gcc RUNTESTFLAGS="--target_board=unix'{-m64}' powerpc.exp=gcc.target/powerpc/combine-2-2.c"
# of expected passes		2


So, yeah, only for -m32 for me too.

Ah good.  Reproduced, confirmed, all that.  Thanks.
Comment 4 Richard Biener 2024-04-10 06:01:19 UTC 
Reverted for GCC 14 but will re-appear in GCC 15.
