            Bug ID: 111236
           Summary: ICE in in extract_insn, at recog.cc:2791 on s390x with
                    -Og -march=z13
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: fkastl at suse dot cz
  Target Milestone: ---
              Host: x86_64-linux
            Target: s390x-linux-gnu

With a cross compiler (revision 85ad41a494e) configured with:

/home/worker/buildworker/tiber-gcc-trunk-s390x/build/configure
--enable-languages=c,c++,fortran,rust,m2 --disable-bootstrap
--disable-libsanitizer --disable-multilib --enable-checking=release
--prefix=/home/worker/cross --target=s390x-linux-gnu
--with-as=/usr/bin/s390x-suse-linux-as

On the GCC testcase gcc/testsuite/gcc.dg/analyzer/torture/pr59037.c

Running it with:

~/cross/bin/s390x-linux-gnu-gcc
/home/worker/buildworker/tiber-option-juggler/build/gcc/testsuite/gcc.dg/analyzer/torture/pr59037.c
