From 35641ecc3752d8da2c85a0c71e738b3f922f24a8 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Mon, 7 Mar 2005 03:19:50 +0000 Subject: [PATCH] move the reassociation pass after the LICM pass. This speeds up mgrid from 10.27s to 9.57s with the CBE. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20508 91177308-0d34-0410-b5e6-96231b3b80d8 --- tools/gccas/gccas.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/tools/gccas/gccas.cpp b/tools/gccas/gccas.cpp index 83de4ebe253..7e22235f7c0 100644 --- a/tools/gccas/gccas.cpp +++ b/tools/gccas/gccas.cpp @@ -103,12 +103,12 @@ void AddConfiguredTransformationPasses(PassManager &PM) { addPass(PM, createScalarReplAggregatesPass()); // Break up aggregate allocas addPass(PM, createInstructionCombiningPass()); // Combine silly seq's - addPass(PM, createReassociatePass()); // Reassociate expressions addPass(PM, createInstructionCombiningPass()); // Combine silly seq's addPass(PM, createTailCallEliminationPass()); // Eliminate tail calls addPass(PM, createCFGSimplificationPass()); // Merge & remove BBs addPass(PM, createLICMPass()); // Hoist loop invariants - addPass(PM, createInstructionCombiningPass()); // Clean up after the unroller + addPass(PM, createReassociatePass()); // Reassociate expressions + addPass(PM, createInstructionCombiningPass()); // Clean up after LICM/reassoc addPass(PM, createIndVarSimplifyPass()); // Canonicalize indvars addPass(PM, createLoopUnrollPass()); // Unroll small loops addPass(PM, createInstructionCombiningPass()); // Clean up after the unroller -- 2.34.1
