Bug ID: 97933
Summary: [11 Regression] Bootstrap failure on s390x-linux
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
Target Milestone: ---
../configure --target s390x-linux-gnu --enable-languages=c,c++
--enable-checking=release --disable-multilib --with-system-zlib
--enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object
--enable-linker-build-id --with-gcc-major-version-only
--with-linker-hash-style=gnu --enable-plugin --enable-initfini-array --with-isl
--enable-gnu-indirect-function --with-long-double-128 --with-arch=zEC12
--with-tune=z13 --enable-decimal-float
fails both profiledbootstrap and bootstrap (no LTO in either case), while
building stage2 libgcc. The ICE is e.g. on decDouble.c:
Program received signal SIGSEGV, Segmentation fault.

stage1 cc1 doesn't ICE though, nor can reproduce it in a cross-compiler from
x86_64-linux (not even with valgrind annotations under valgrind), so maybe
stage2 is miscompiled.

Sorry for causing this error. It is clearly my mistake. I've started to work
on this. The fix will be ready tomorrow.
