Subject: [PATCH] Fix PR tree-optimization/71314
Date: Tue, 31 May 2016 08:22:00 -0000 [thread overview]
Message-ID: <20160530195052.24225-1-patrick@parcs.ath.cx> (raw)
The test case ssa-thread-14.c expects that non-short-circuit logical ops
are used so it fails on targets that don't use such ops by default. To
fix, I copied the dg directives from tree-ssa/reassoc-35.c which look
reasonable. Does this look OK to commit?
gcc/testsuite/ChangeLog:
PR tree-optimization/71314
* gcc.dg/tree-ssa/ssa-thread-14.c: Adjust target selector. Pass
-mbranch-cost= 2.
