--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Looking at 20011029-1.c -Os on ppc64le, replace_rtx is called from
rs6000_frame_related from rs6000_emit_prologue, on a large parallel containing
(use (reg:DI 12 12))
and from is:
(reg:DI 12 12)
(but not pointer equal) and to is:
(plus:DI (reg/f:DI 1 1)
(const_int -144 [0xffffffffffffff70]))
I'm going to revert the rtlanal.c change and we need a new function with the
new behavior and sort this out later.
