From caaa49336b47b542d7255a8455fbab2e14a20ec5 Mon Sep 17 00:00:00 2001 From: Daniel Dunbar Date: Sat, 8 Aug 2009 17:43:09 +0000 Subject: More ProfileInfo improvements. - Part of optimal static profiling patch sequence by Andreas Neustifter. - Store edge, block, and function information separately for each functions (instead of in one giant map). - Return frequencies as double instead of int, and use a sentinel value for missing information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78477 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/Instrumentation/BlockProfiling.cpp | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'lib/Transforms/Instrumentation/BlockProfiling.cpp') diff --git a/lib/Transforms/Instrumentation/BlockProfiling.cpp b/lib/Transforms/Instrumentation/BlockProfiling.cpp index 9139c92235..91020755c2 100644 --- a/lib/Transforms/Instrumentation/BlockProfiling.cpp +++ b/lib/Transforms/Instrumentation/BlockProfiling.cpp @@ -106,7 +106,8 @@ bool BlockProfiler::runOnModule(Module &M) { unsigned NumBlocks = 0; for (Module::iterator I = M.begin(), E = M.end(); I != E; ++I) - NumBlocks += I->size(); + if (!I->isDeclaration()) + NumBlocks += I->size(); const Type *ATy = ArrayType::get(Type::Int32Ty, NumBlocks); GlobalVariable *Counters = @@ -115,10 +116,12 @@ bool BlockProfiler::runOnModule(Module &M) { // Instrument all of the blocks... unsigned i = 0; - for (Module::iterator I = M.begin(), E = M.end(); I != E; ++I) + for (Module::iterator I = M.begin(), E = M.end(); I != E; ++I) { + if (I->isDeclaration()) continue; for (Function::iterator BB = I->begin(), E = I->end(); BB != E; ++BB) // Insert counter at the start of the block IncrementCounterInBlock(BB, i++, Counters); + } // Add the initialization call to main.
