From 1a07e191807032584b669319339341c3fa937212 Mon Sep 17 00:00:00 2001 From: Tobias Grosser Date: Fri, 26 Jun 2015 21:58:42 +0000 Subject: [PATCH] Increase the dependence-analysis compute out As Polly got a lot faster after the small-integer-optimization imath patch, we now increase the compute out to optimize larger kernels. This should also expose additional slow-downs for us to address. In LNT this gives us a 3.4x speedup on 3mm, at a cost of a 2x increase in compile time (now 0.77s). reg_detect, oorafft and adi also show some compile time increases. This compile time cost is divided between more time in isl and more time in LLVM's backends due to increased code size (versioning and tiling). llvm-svn: 240840 --- polly/lib/Analysis/DependenceInfo.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/polly/lib/Analysis/DependenceInfo.cpp b/polly/lib/Analysis/DependenceInfo.cpp index 66a55af..afb4ab7 100644 --- a/polly/lib/Analysis/DependenceInfo.cpp +++ b/polly/lib/Analysis/DependenceInfo.cpp @@ -45,7 +45,7 @@ static cl::opt OptComputeOut( "polly-dependences-computeout", cl::desc("Bound the dependence analysis by a maximal amount of " "computational steps (0 means no bound)"), - cl::Hidden, cl::init(250000), cl::ZeroOrMore, cl::cat(PollyCategory)); + cl::Hidden, cl::init(410000), cl::ZeroOrMore, cl::cat(PollyCategory)); static cl::opt LegalityCheckDisabled( "disable-polly-legality", cl::desc("Disable polly legality check"), -- 2.7.4
