From 63f932ca3c91ea8ac5b592158f5e8ef7de550547 Mon Sep 17 00:00:00 2001 From: Meador Inge Date: Fri, 30 Nov 2012 04:05:06 +0000 Subject: Move library call simplification statistic to instcombine The simplify-libcalls pass maintained a statistic to count the number of library calls that have been simplified. Now that library call simplification is being carried out in instcombine the statistic should be moved to there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168975 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/InstCombine/InstCombineCalls.cpp | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'lib/Transforms/InstCombine/InstCombineCalls.cpp') diff --git a/lib/Transforms/InstCombine/InstCombineCalls.cpp b/lib/Transforms/InstCombine/InstCombineCalls.cpp index b7b45a2..60244c7 100644 --- a/lib/Transforms/InstCombine/InstCombineCalls.cpp +++ b/lib/Transforms/InstCombine/InstCombineCalls.cpp @@ -14,11 +14,14 @@ #include "InstCombine.h" #include "llvm/Support/CallSite.h" #include "llvm/DataLayout.h" +#include "llvm/ADT/Statistic.h" #include "llvm/Analysis/MemoryBuiltins.h" #include "llvm/Transforms/Utils/BuildLibCalls.h" #include "llvm/Transforms/Utils/Local.h" using namespace llvm; +STATISTIC(NumSimplified, "Number of library calls simplified"); + /// getPromotedType - Return the specified type promoted as it would be to pass /// though a va_arg area. static Type *getPromotedType(Type *Ty) { @@ -785,8 +788,10 @@ static bool isSafeToEliminateVarargsCast(const CallSite CS, Instruction *InstCombiner::tryOptimizeCall(CallInst *CI, const DataLayout *TD) { if (CI->getCalledFunction() == 0) return 0; - if (Value *With = Simplifier->optimizeCall(CI)) + if (Value *With = Simplifier->optimizeCall(CI)) { + ++NumSimplified; return CI->use_empty() ?
