[Bug optimization/13031] [3.3 regression] ICE (unrecognizable insn) when building gnome-libs-1.4.2


------- Additional Comments From janis187 at us dot ibm dot com  2003-12-10 19:13 -------
The regression in PR 13031 was introduced or exposed by this patch:

2002-06-10  Roger Sayle  <roger@eyesopen.com>

        * toplev.c (rest_of_compilation): Disable early if-conversion pass.
        * gcse.c (bypass_conditional_jumps): Fix typo in setcc test.

The test case starts passing on mainline with this patch:

2003-02-08  Zdenek Dvorak  <rakdver@atrey.karlin.mff.cuni.cz>

        * cfgloop.h (fix_loop_placement, can_duplicate_loop_p,
        duplicate_loop_to_header_edge, loopify, remove_path, split_loop_bb):
        Declare.
        (DLTHE_FLAG_UPDATE_FREQ): New.
        * cfgloopmanip.c
        [lots more]

The hunts took place with mainline sources on i686-pc-linux-gnu with a
cross cc1 for alphaev67-unknown-linux, using the test case in comment
#6 compiled with -O3.
