From d895e29e88387d97dad1ef2d26184145e4029c56 Mon Sep 17 00:00:00 2001 From: Chandler Carruth Date: Wed, 20 Nov 2013 04:39:16 +0000 Subject: [PM] Make the function pass manager more regular. The FunctionPassManager is now itself a function pass. When run over a function, it runs all N of its passes over that function. This is the 1:N mapping in the pass dimension only. This allows it to be used in either a ModulePassManager or potentially some other manager that works on IR units which are supersets of Functions. This commit also adds the obvious adaptor to map from a module pass to a function pass, running the function pass across every function in the module. The test has been updated to use this new pattern. llvm-svn: 195192 --- llvm/lib/IR/PassManager.cpp | 15 +++++++-------- 1 file changed, 7 insertions(+), 8 deletions(-) (limited to 'llvm/lib/IR/PassManager.cpp') diff --git a/llvm/lib/IR/PassManager.cpp b/llvm/lib/IR/PassManager.cpp index b53a2b9671d..35fc534151a 100644 --- a/llvm/lib/IR/PassManager.cpp +++ b/llvm/lib/IR/PassManager.cpp @@ -53,15 +53,14 @@ void ModuleAnalysisManager::invalidateImpl(void *PassID, Module *M) { ModuleAnalysisResults.erase(PassID); } -bool FunctionPassManager::run(Module *M) { +bool FunctionPassManager::run(Function *F) { bool Changed = false; - for (Module::iterator I = M->begin(), E = M->end(); I != E; ++I) - for (unsigned Idx = 0, Size = Passes.size(); Idx != Size; ++Idx) - if (Passes[Idx]->run(I)) { - Changed = true; - if (AM) - AM->invalidateAll(I); - } + for (unsigned Idx = 0, Size = Passes.size(); Idx != Size; ++Idx) + if (Passes[Idx]->run(F)) { + Changed = true; + if (AM) + AM->invalidateAll(F); + } return Changed; } -- cgit v1.2.3
