--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Though, e.g. on
void bar (int a, int b);

void
foo (int a, int b)
{
  bar (b, 6);
}
like on the above mentioned testcase, I see REG_EQUIV with (mem (argp)) on the
loads as well as (use (mem (argp))) on the call insn after reload both with
trunk as well as 4.8.  The uses on sibling call insns with argp date apparently
back to 4.7, the REG_EQUIV with (mem (argp)) rather than sp/bp related date
back to 4.8.
