            Bug ID: 64403
           Summary: m32c-elf ICE with -mcpu=m32cm and cleanup
           Product: gcc
           Version: 4.9.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: yselkowi at redhat dot com
              Host: x86_64-cygwin
            Target: m32c-elf, m32c-rtems
             Build: x86_64-cygwin

While building 4.9.2 with binutils-2.25 for m32c-{elf,rtems} targets, the m32cm
multilib libgcc configure (but not the main one) fails during the SjLj
exceptions test:

$ cat conftest.c
void bar ();
void clean (int *);
void foo ()
{
  int i __attribute__ ((cleanup (clean)));
  bar();
}

$ ./gcc/xgcc -B gcc -c -fexceptions -save-temps conftest.c
[succeeds]
$ ./gcc/xgcc -B gcc -c -mcpu=m32cm -fexceptions -save-temps conftest.c
conftest.c: In function âfooâ:
conftest.c:7:1: error: insn does not satisfy its constraints:
 }
 ^
(insn 52 38 23 (set (reg:SI 2 r1 [29])
        (reg:SI 4 a0)) 99 {movsi_24}
     (nil))
conftest.c:7:1: internal compiler error: in final_scan_insn, at final.c:2891
