r152880 - in /branches/reload-v2/gcc: ChangeLog...


Author: law
Date: Thu Oct 15 23:07:08 2009
New Revision: 152880

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=152880
Log:
	* ira-reload.c (ira_bad_reload_regno): New function.
	(ira_bad_reload_regno_1): Likewise.
	* ira.h (ira_bad_reload_regno): Declare.
	* reload1.c (allocate_reload_reg): Use ira_bad_reload_regno.

Avoids regressions after splitting unallocated global pseudos by 
not making insanely dumb choices for spill registers.
