--- Comment #11 from Peter A. Bigot <bigotp at acm dot org> 2011-10-17 11:16:16 UTC --- Richard: Thanks for the fix. For my non-integrated target I don't need it backported to 4.6 since I have a separate way to provide the patch. As I recall, the original patch didn't apply to 4.6 cleanly due to subsequent changes to tree-ssa-forwprop.c; a patch at the fork of gcc-4_6-branch from trunk is available at: http://mspgcc.git.sourceforge.net/git/gitweb.cgi?p=mspgcc/gcc;a=commit;h=21a41ea517c2e60d3a910aca8012a2c0d57b1005
