Hi: At last of function change_loop, gcc try to change ALLOCNO_REG of local allocno. In the loop, ALLOCNO_SOMEWHERE_RENAMED_P (allocno) is set if allocno is not caps. Don't understand why the flag is set here. Doesn't all local allocnos' flag are set in this loop? seems conflicting with function set_allocno_somewhere_renamed_p and comments about that flag in ira-int.h
Any tips? Thanks in advance. -- Best Regards.
