-Subject: [PATCH] 	PR rtl-optimization/48549
- 	* combine.c (propagate_for_debug): Also stop after BB_END of
- 	this_basic_block.  Process LAST and just stop processing after it.
- 	(combine_instructions): If last_combined_insn has been deleted,
- 	set last_combined_insn to its PREV_INSN.
-
-	* g++.dg/opt/pr48549.C: New test.
