Bug ID: 115876
Summary: runtime errors during bootstrap with -O3 -march=znver3
-fno-var-tracking-assignments
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
For a bootstrap with this configure script:
../trunk/configure \
--disable-multilib \
--disable-werror \
--with-build-config=bootstrap-asan \
--with-build-config=bootstrap-ubsan \
--enable-checking=yes \
--enable-languages=c,c++,fortran
sed 's;-O2;-O3 -march=znver3 -fno-var-tracking-assignments;' < Makefile >
Makefile.tmp
diff Makefile Makefile.tmp
mv Makefile.tmp Makefile
I get:
$ grep error: mk.out
