            Bug ID: 66363
           Summary: ICE in modified test inline-36.c
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vogt at linux dot vnet.ibm.com
  Target Milestone: ---

This small test program derived from gcc.dg/inline-39.c (by adding the inline
keyword) exposes an ICE on s390x, but this may be/probably is a problem on all
platforms:

-- snip --
int g;
inline __attribute__((always_inline)) void bar (void)
{
  g++;
}

void foo2 (void)
{
  bar();
}
-- snip --

Compiling with "-O2 -fdisable-tree-einline=foo2 -fdisable-ipa-inline" results
in an ICE:

-- snip --
cc1: note: disable pass tree-einline for function foo2                          
cc1: note: disable pass ipa-inline for functions in the range of [0,
