From fa709768b91df14bb7b5606700d92c3c10aba625 Mon Sep 17 00:00:00 2001 From: Michael Gottesman Date: Mon, 13 May 2013 18:29:07 +0000 Subject: [PATCH] [objc-arc] Move the before optimization statistics gathering phase out of OptimizeIndividualCalls. This makes the statistics gathering completely independent of the actual optimization occuring, preventing any sort of bleeding over from occuring. Additionally, it simplifies a switch statement in the non-statistic gathering case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181719 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/ObjCARC/ObjCARCOpts.cpp | 15 +++++++-------- 1 file changed, 7 insertions(+), 8 deletions(-) diff --git a/lib/Transforms/ObjCARC/ObjCARCOpts.cpp b/lib/Transforms/ObjCARC/ObjCARCOpts.cpp index 43e2e200353..6d2d630bb6f 100644 --- a/lib/Transforms/ObjCARC/ObjCARCOpts.cpp +++ b/lib/Transforms/ObjCARC/ObjCARCOpts.cpp @@ -1440,11 +1440,7 @@ void ObjCARCOpt::OptimizeIndividualCalls(Function &F) { case IC_RetainBlock: // If we strength reduce an objc_retainBlock to an objc_retain, continue // onto the objc_retain peephole optimizations.
