No, I don't want to apply it until the branch has fully recovered from its
January chaos.
This patch
2004-01-16 Jan Hubicka <jh@suse.cz>
PR opt/11350
* cfgcleanup.c (try_optimize_cfg): Suppress tablejump removal
after reload.
* cfgrtl.c (try_redirect_by_replacing_branch): Likewise.
caused a disaster on mainline on anything else than x86.
This patch

PR optimization/10392
* reload.c (can_reload_into): New function.
(push_reload): Use it.
should never have been put on the branch at this point.
I found this patch
2004-01-09 Richard Henderson <rth@redhat.com>
* recog.c (constrain_operands): Validate mem operands.
very risky too.
So don't count on me to put a patch to reload on the branch.
