From 6c18d1aac08df0143d9a9810261421faeac81d4a Mon Sep 17 00:00:00 2001 From: Owen Anderson Date: Tue, 19 Oct 2010 17:21:58 +0000 Subject: Get rid of static constructors for pass registration. Instead, every pass exposes an initializeMyPassFunction(), which must be called in the pass's constructor. This function uses static dependency declarations to recursively initialize the pass's dependencies. Clients that only create passes through the createFooPass() APIs will require no changes. Clients that want to use the CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h before parsing commandline arguments. I have tested this with all standard configurations of clang and llvm-gcc on Darwin. It is possible that there are problems with the static dependencies that will only be visible with non-standard options. If you encounter any crash in pass registration/creation, please send the testcase to me directly. llvm-svn: 116820 --- llvm/lib/CodeGen/StackSlotColoring.cpp | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) (limited to 'llvm/lib/CodeGen/StackSlotColoring.cpp') diff --git a/llvm/lib/CodeGen/StackSlotColoring.cpp b/llvm/lib/CodeGen/StackSlotColoring.cpp index ce675957bd1..9b7f553ed41 100644 --- a/llvm/lib/CodeGen/StackSlotColoring.cpp +++ b/llvm/lib/CodeGen/StackSlotColoring.cpp @@ -95,9 +95,13 @@ namespace { public: static char ID; // Pass identification StackSlotColoring() : - MachineFunctionPass(ID), ColorWithRegs(false), NextColor(-1) {} + MachineFunctionPass(ID), ColorWithRegs(false), NextColor(-1) { + initializeStackSlotColoringPass(*PassRegistry::getPassRegistry()); + } StackSlotColoring(bool RegColor) : - MachineFunctionPass(ID), ColorWithRegs(RegColor), NextColor(-1) {} + MachineFunctionPass(ID), ColorWithRegs(RegColor), NextColor(-1) { + initializeStackSlotColoringPass(*PassRegistry::getPassRegistry()); + } virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.setPreservesCFG(); -- cgit v1.2.3
