From 6aa5c26c81071e22a23a6f0ae7dcac6080ad6597 Mon Sep 17 00:00:00 2001 From: Chandler Carruth Date: Wed, 19 Oct 2011 10:12:41 +0000 Subject: Add pass printing support to BlockFrequencyInfo pass. The implementation layer already had support for printing the results of this analysis, but the wiring was missing. Now that printing the analysis works, actually bring some of this analysis, and the BranchProbabilityInfo analysis that it wraps, under test! I'm planning on fixing some bugs and doing other work here, so having a nice place to add regression tests and a way to observe the results is really useful. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142491 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Analysis/BlockFrequencyInfo.cpp | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'lib') diff --git a/lib/Analysis/BlockFrequencyInfo.cpp b/lib/Analysis/BlockFrequencyInfo.cpp index ee89915..d16665f 100644 --- a/lib/Analysis/BlockFrequencyInfo.cpp +++ b/lib/Analysis/BlockFrequencyInfo.cpp @@ -49,6 +49,10 @@ bool BlockFrequencyInfo::runOnFunction(Function &F) { return false; } +void BlockFrequencyInfo::print(raw_ostream &O, const Module *) const { + if (BFI) BFI->print(O); +} + /// getblockFreq - Return block frequency.
