From f6e43bc7968df6794e518e964c3428fff86dc0f8 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Thu, 18 Mar 2004 05:46:10 +0000 Subject: [PATCH] Add statistics to the loop extractor. The loop extractor has successfully extracted all 63 loops for Olden/bh without crashing and without miscompiling the program!!! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12491 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/IPO/LoopExtractor.cpp | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/lib/Transforms/IPO/LoopExtractor.cpp b/lib/Transforms/IPO/LoopExtractor.cpp index 083b11684cc..6b033b40827 100644 --- a/lib/Transforms/IPO/LoopExtractor.cpp +++ b/lib/Transforms/IPO/LoopExtractor.cpp @@ -22,9 +22,12 @@ #include "llvm/Analysis/LoopInfo.h" #include "llvm/Transforms/Scalar.h" #include "llvm/Transforms/Utils/FunctionUtils.h" +#include "Support/Statistic.h" using namespace llvm; namespace { + Statistic<> NumExtracted("loop-extract", "Number of loops extracted"); + // FIXME: This is not a function pass, but the PassManager doesn't allow // Module passes to require FunctionPasses, so we can't get loop info if we're // not a function pass. @@ -72,6 +75,7 @@ bool LoopExtractor::runOnFunction(Function &F) { if (NumLoops == 0) return Changed; --NumLoops; Changed |= ExtractLoop(DS, *i) != 0; + ++NumExtracted; } } else { // Otherwise there is exactly one top-level loop.
