+ * cgraph.c (cgraph_create_edge_including_clones): Add old_stmt parameter;
+ update edge if it already exists.

+ (verify_reg_in_set): New function, broken out of verify_reg_tracked.
+ (verify_reg_tracked): Use it.
+ (scan_rtx_reg): When seeing a use involving a superset of the
+ registers in an existing chain, enlarge that chain. Otherwise,
+ allow subsets and set fail_current_block for all other kinds of
+ overlap.
+ (hide_operands): New argument UNTRACKED_OPERANDS; callers changed.
+ Do not modify operands when the bit with the corresponding number
+ is set in that bitmap.
+ (build_def_use): When we see matching operands with different
+ modes, don't set fail_current_block, but keep track of such
+ operands in a bitmap if their registers aren't already tracked
+ in an open chain. Pass this bitmap to all hide_operands calls.
