            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.
