The regression reported in PR 11634 still exists in the 3.3-branch
but was fixed on the mainline with this patch:
2003-09-03 Mostafa Hagog <[EMAIL PROTECTED]>
* gcse.c (replace_one_set): New function.
(pre_insert_copy_insn): Change the order of copying
to make copy propagation discover additional PRE opportunities.
The test case demonstrates another problem For about 8% of the cross
compilers that were built for my regression hunt there was an ICE
in common_handle_option. After the patch that fixes the ICE in
verify_local_live_at_start, the compiler sometimes (about 10% of the
time) acts as if random options had been specified.
