------- Comment #1 from jakub at gcc dot gnu dot org 2009-09-14 08:18 ------- Created an attachment (id=18580) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=18580&action=view) gcc45-pr41353.patch
Here is a small patch that allows us to get at least a little bit toward fixing the first testcase. At *.expand time it fills the location with the pseudos of the PARM_DECL, but as it isn't used, that pseudo is optimized away very soon. Either at the point where the pseudo is killed we should handle it (know that PARM_DECLs initially live in the incoming reg/mem), or perhaps already this spot should know about it and handle PARM_DECLs when there is no partition immediately using DECL_INCOMING_RTL. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41353
