                    segfaults w/ -mregparm=3
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---

Currently, main trunk produces wrong code.
I suspect target (but not sure).

Reproduce:
$ gcc/xgcc -Bgcc
../../git/gcc3/gcc/testsuite/gcc.dg/torture/stackalign/non-local-goto-5.c -O1
-mregparm=3 -m32
$ ./a.out
