------- Comment #4 from bernds at codesourcery dot com 2010-03-16 10:56 ------- Created an attachment (id=20117) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=20117&action=view) A patch to fix it.
The andsi3 expander has code to do the right thing, but avoid_expensive_constant prevents it from seeing the constant. This can be fixed by tweaking the rtx_costs to detect the same cases as the expander. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40697
