From 30a507a1f5d6a5646dd3481eba6958424415c886 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159570 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/CppBackend/CPPTargetMachine.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'lib/Target/CppBackend/CPPTargetMachine.h') diff --git a/lib/Target/CppBackend/CPPTargetMachine.h b/lib/Target/CppBackend/CPPTargetMachine.h index 92bca6c..9cbe798 100644 --- a/lib/Target/CppBackend/CPPTargetMachine.h +++ b/lib/Target/CppBackend/CPPTargetMachine.h @@ -31,7 +31,9 @@ struct CPPTargetMachine : public TargetMachine { virtual bool addPassesToEmitFile(PassManagerBase &PM, formatted_raw_ostream &Out, CodeGenFileType FileType, - bool DisableVerify); + bool DisableVerify, + AnalysisID StartAfter, + AnalysisID StopAfter); virtual const TargetData *getTargetData() const { return 0; } }; -- cgit v1.1
