--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> 2013-03-08 12:25:50 UTC --- Created attachment 29620 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29620 inliner patches For the inliner I've now synced copy_tree_body_r and remap_gimple_op_r wrt MEM_REFs (to no avail). I also added debug-expr remapping to copy_debug_stmt (as the tree-ssa-live.c code shows not all debug-expr decls are in local-decls), to no avail either. See attachment.
