Only catch-all-1.m fails now:

[Bug rtl-optimization/23393] catchall-1.m fails at -Os

[pinskia at gcc dot gnu dot org]

The interesting thing is that catchall-1.m fails now (along with local-variables-1.m):
http://gcc.gnu.org/ml/gcc-testresults/2005-09/msg00051.html

But did less than a day ago:
http://gcc.gnu.org/ml/gcc-testresults/2005-09/msg00035.html

But instead finally-1.m did.

[Bug rtl-optimization/23393] [4.1 Regression] catchall-1.m and local-variables-1.m fails at -Os

[pinskia at gcc dot gnu dot org]

------- Additional Comments From pinskia at gcc dot gnu dot org  2005-09-02 01:54 -------
Since both of these tests passed yesterday, this is a regression now.
The only change between those two testuiste which was related to this failure is:
+2005-09-01  Jakub Jelinek  <jakub@redhat.com>
+
+       PR rtl-optimization/23478
+       * local-alloc.c (struct qty): Add n_throwing_calls_crossed field.
+       (alloc_qty): Initialize it.
+       (update_equiv_regs): Clear REG_N_THROWING_CALLS_CROSSED.
+       (combine_regs): Combine also n_throwing_calls_crossed fields.
+       (find_free_reg): Don't attempt to caller-save pseudos crossing
+       calls that might throw.
+       * global.c (struct allocno): Add throwing_calls_crossed field.
+       (global_alloc): Revert 2005-08-22 change.  Initialize
+       throwing_calls_crossed.
+       (find_reg): Don't attempt to caller-save pseudos crossing calls that
+       might throw.

All others were tree level changes which should not effect -O2 vs -Os.

Yeah.  But if I also back out
http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/gcc/global.c.diff?cvsroot=gcc&r1=1.130&r2=1.131
we are back to what is seen on HEAD now.  The state between that 2005-08-22
checkin and 2005-09-01 checkin was wrong, caused too many registers to be
unnecessarily forced into memory and as such drastically changed what subsequent
optimizations did.  So, unless these failures have been a regression before
2005-08-22, please don't treat them as such.

catchall-1.m is a regression.
