From 081c34b725980f995be9080eaec24cd3dfaaf065 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116820 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/Scalar/LoopUnrollPass.cpp | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'lib/Transforms/Scalar/LoopUnrollPass.cpp') diff --git a/lib/Transforms/Scalar/LoopUnrollPass.cpp b/lib/Transforms/Scalar/LoopUnrollPass.cpp index 8429ba47ec..dabb9481b4 100644 --- a/lib/Transforms/Scalar/LoopUnrollPass.cpp +++ b/lib/Transforms/Scalar/LoopUnrollPass.cpp @@ -43,7 +43,9 @@ namespace { class LoopUnroll : public LoopPass { public: static char ID; // Pass ID, replacement for typeid - LoopUnroll() : LoopPass(ID) {} + LoopUnroll() : LoopPass(ID) { + initializeLoopUnrollPass(*PassRegistry::getPassRegistry()); + } /// A magic value for use with the Threshold parameter to indicate /// that the loop unroll should be performed regardless of how much -- cgit v1.2.3
