From e9d22c8ab3c3b73a9ed5892e120c869b12eeb85c Mon Sep 17 00:00:00 2001 From: Segher Boessenkool Date: Thu, 29 Jun 2017 19:28:47 +0200 Subject: [PATCH] combine: Print insns with the cost dump In the combine dump file, at the start there is a list of the RTL cost of every insn. The only thing listed about the insns is the UID though. To make it more useful, this patch prints the insn itself as well (in slim format). * combine.c (combine_instructions): Print insns to dump_file, together with their costs.
