From cac3b9063320fdace01f1e994addf3b6823c8030 Mon Sep 17 00:00:00 2001 From: Bob Wilson Date: Mon, 2 Jul 2012 19:48:45 +0000 Subject: Extend TargetPassConfig to allow running only a subset of the normal passes. This is still a work in progress but I believe it is currently good enough to fix PR13122 "Need unit test driver for codegen IR passes". For example, you can run llc with -stop-after=loop-reduce to have it dump out the IR after running LSR. Serializing machine-level IR is not yet supported but we have some patches in progress for that. The plan is to serialize the IR to a YAML file, containing separate sections for the LLVM IR, machine-level IR, and whatever other info is needed. Chad suggested that we stash the stop-after pass in the YAML file and use that instead of the start-after option to figure out where to restart the compilation. I think that's a great idea, but since it's not implemented yet I put the -start-after option into this patch for testing purposes. llvm-svn: 159570 --- llvm/lib/Target/CppBackend/CPPBackend.cpp | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'llvm/lib/Target/CppBackend/CPPBackend.cpp') diff --git a/llvm/lib/Target/CppBackend/CPPBackend.cpp b/llvm/lib/Target/CppBackend/CPPBackend.cpp index 0ea2a29..c8e757b 100644 --- a/llvm/lib/Target/CppBackend/CPPBackend.cpp +++ b/llvm/lib/Target/CppBackend/CPPBackend.cpp @@ -2101,7 +2101,9 @@ char CppWriter::ID = 0; bool CPPTargetMachine::addPassesToEmitFile(PassManagerBase &PM, formatted_raw_ostream &o, CodeGenFileType FileType, - bool DisableVerify) { + bool DisableVerify, + AnalysisID StartAfter, + AnalysisID StopAfter) { if (FileType != TargetMachine::CGFT_AssemblyFile) return true; PM.add(new CppWriter(o)); return false; -- cgit v1.1
