From 57e6b2d1f3de0bf459e96f7038e692d624f7e580 Mon Sep 17 00:00:00 2001 From: Tom Stellard Date: Sat, 27 Jul 2013 00:01:07 +0000 Subject: SimplifyCFG: Use parallel-and and parallel-or mode to consolidate branch conditions Merge consecutive if-regions if they contain identical statements. Both transformations reduce number of branches. The transformation is guarded by a target-hook, and is currently enabled only for +R600, but the correctness has been tested on X86 target using a variety of CPU benchmarks.
