Bug ID: 118418
Summary: [15 Regression][gcn] Compiler selftest ICE in
assert_rtx_eq_at, at selftest-rtl.cc:57 / FAIL:
ASSERT_RTX_EQ (val, folded) since
r15-6777-g06c4cf398947b5
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Keywords: build, ice-on-valid-code
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
CC: ams at gcc dot gnu.org, rsandifo at gcc dot gnu.org
Target Milestone: ---
Target: gcn
Since the commit
r15-6777-g06c4cf398947b5 rtl: Remove invalid compare simplification
[PR117186]
the GCC build fails with the following ICE during the self test at the
end of the build.
* * *
IMHO, as no target-code linking/assembling is involved, just configuring
GCC with
..../configure --target=amdgcn-amdhsa
should be enough for reproducing. Otherwise, the build descriptions at
https://gcc.gnu.org/install/specific.html#amdgcn-x-amdhsa
and https://gcc.gnu.org/wiki/Offloading#Building_and_Obtaining_GCC
should help.
