Subject: [Bug c/107364] New: ICE on Via Nehemiah with --march=native
Date: Sun, 23 Oct 2022 10:47:04 +0000 [thread overview]
Message-ID: <bug-107364-4@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107364
Bug ID: 107364
Summary: ICE on Via Nehemiah with --march=native
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: orzel at freehackers dot org
Target Milestone: ---

power management:
The compiler crashes when using -march=native. You dont need to compile for it
to crash, --help=target is enough. As a result, gcc can't build itself anymore.
The last known 'working' version is gcc 9. Tested are gcc 10, 11, and 12, all
crashing the same way. This is how it looks:
chopin /etc # gcc-12 -Q --help=target -march=native -freport-bug
gcc-12: internal compiler error: in cpu_indicator_init, at
common/config/i386/cpuinfo.h:986
0xb7cd535e __libc_start_main
???:0
Please submit a full bug report, with preprocessed source.
Please include the complete backtrace with any bug report.
See <https://bugs.gentoo.org/> for instructions.

This is a gentoo distribution. There's an option to compile GCC without any
gentoo-specific patches. The compiler crashes also in this case (that is, when
using the 'stage1' xgcc compiler to build the, i guess, stage2?). That's why we
think the bug was worth reporting upstream.
