From 4e0cc51d7974029aa2bbffce08e2c878f529f98a Mon Sep 17 00:00:00 2001 From: Juergen Ributzka Date: Mon, 28 Apr 2014 18:19:25 +0000 Subject: [PM] Add pass run listeners to the pass manager. This commit provides the necessary C/C++ APIs and infastructure to enable fine- grain progress report and safe suspension points after each pass in the pass manager. Clients can provide a callback function to the pass manager to call after each pass. This can be used in a variety of ways (progress report, dumping of IR between passes, safe suspension of threads, etc). The run listener list is maintained in the LLVMContext, which allows a multi- threaded client to be only informed for it's own thread. This of course assumes that the client created a LLVMContext for each thread. This fixes git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207430 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/IR/LLVMContext.cpp | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) (limited to 'lib/IR/LLVMContext.cpp') diff --git a/lib/IR/LLVMContext.cpp b/lib/IR/LLVMContext.cpp index 588e1217bd..b2d3bc9061 100644 --- a/lib/IR/LLVMContext.cpp +++ b/lib/IR/LLVMContext.cpp @@ -214,3 +214,23 @@ void LLVMContext::getMDKindNames(SmallVectorImpl &Names) const { E = pImpl->CustomMDKindNames.end(); I != E; ++I) Names[I->second] = I->first(); } + +//===----------------------------------------------------------------------===// +// Pass Run Listeners +//===----------------------------------------------------------------------===// +/// Notify that we finished running a pass. +void LLVMContext::notifyPassRun(Pass *P, Module *M, Function *F, BasicBlock *BB) +{ + pImpl->notifyPassRun(this, P, M, F, BB); +} +/// Register the given PassRunListener to receive notifyPassRun() callbacks +/// whenever a pass ran.
