[Bug target/32338] New: [4.3 Regression] Error: .prologue within prologue

["tbm at cyrius dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I'm getting the following assembler error with current gcc 4.3.  This
worked with 20070604 and is probably due to the dataflow merge.  This is
possible the same as, or related to, PR32337, but I cannot tell for sure.

tbm@coconut0:~$ /usr/lib/gcc-snapshot/bin/gcc -c -O2 -fno-omit-frame-pointer
skalibs-dns_transmit.c
/tmp/cc1yk7fL.s: Assembler messages:
/tmp/cc1yk7fL.s:93: Warning: .restore outside of body region
/tmp/cc1yk7fL.s:101: Error: .prologue within prologue

Testcase:


struct dns_transmit
{
};
firstudp (struct dns_transmit *d)
{
}
firsttcp (struct dns_transmit *d)
{
}
dns_transmit_start (struct dns_transmit *d, char const *q)
{
  unsigned int len;
  len = dns_domain_length (q);
  if (len > 512)
    return firsttcp (d);
  return firstudp (d);
}
