--- Comment #1 from Martin Jambor <jamborm at gcc dot gnu.org> ---
I was not able to reproduce this error on gcc112 on compile farm
(powerpc64le-unknown-linux-gnu).

OK, so now confirmed (on gcc120 from compile farm) but it also fails with
14d0c509898 reverted. I'll try reverting 1be18ea110a instead.

Yeah, that seems to be it. If I cannot fix this tomorrow I'll revert the patch
from master.

As expected, it is an -fcompare-debug failure:

Revert "ipa: Self-DCE of uses of removed call LHSs (PR 108007)"
This reverts commit 1be18ea110a2d69570dbc494588a7c73173883be.
As reported in PR bootstrap/111688, it broke ppc64le bootstrap because
of a debug-compare failure.

I have reverted the offending commit, ppc64le bootstrap should be restored
(which I also tested, though only with C and C++ to speed it up). Sorry for
the breakage.
