[Bug optimization/11634] [3.3/3.4 regression] [hppa] ICE in verify_local_live_at_start, at flow.c:555

------- Additional Comments From janis187 at us dot ibm dot com  2003-11-24 22:51 -------
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  <mustafa@il.ibm.com>

        * 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.
