------- Comment #6 from bonzini at gnu dot org 2007-02-21 16:23 ------- Created an attachment (id=13083) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=13083&action=view) patch to fix the bug
The logic in trunk's combine with respect to uninitialized variables is correct. We have to look at DF_LR_IN for the entry basic block to find variables that are not used uninitialized. In fact, the name of DF_UR_IN is misleading, as it computes *initialized* registers. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30904
