With the mainline (20030628), I get an ICE with -fnew-ra and -O2:
readelf.c: In function `get_ia64_section_type_name':
readelf.c:2366: error: Abnormal edges for no purpose in bb 1
readelf.c:2366: internal compiler error: verify_flow_info failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

I should say I use -O2 -fnew-ra fot the options.

Unify spelling of new-ra in PRs.

Here is the reduced testcase (10 lines):
const char *get_osabi_name (unsigned int);
const char *
get_ia64_section_type_name (sh_type)
     unsigned int sh_type;
{

  if ((sh_type & 0xFF000000) == (0x70000000 + 0x8000000))
    return get_osabi_name ((sh_type & 0x00FF0000) >> 16);
  return ((void *)0);
}

Andrew, I think your test case can be simplified further
(I ran into this while reducing the testcase for bug 11162
as seen by gcc-3.4-20030903):

int foo(char *p1)
{
        return bar(p1);
}

Here's what I see when I compile it:
$ /usr/gcc-3.4-20030903-glibc-2.3.2/bin/sh4-unknown-linux-gnu-gcc -O2 -fnew-ra
z.c         
z.c: In function `foo':
z.c:4: error: Abnormal edges for no purpose in bb 0
z.c:4: internal compiler error: verify_flow_info failed

You are right that is the simplifier but since bug 11162 is already assigned, marking this one as a 
dup of bug 11162.

*** This bug has been marked as a duplicate of 11162 ***
