From 09ae6e0d77d7eb3339a20c613a6f0a9c391dc9f3 Mon Sep 17 00:00:00 2001 From: Andreas Neustifter Date: Tue, 1 Sep 2009 10:06:05 +0000 Subject: Preparation for Optimal Edge Profiling: Optimal edge profiling is only possible when blocks with no predecessors get an virtual edge (BB,0) that counts the execution frequencies of this function-exiting blocks. This patch makes the necessary changes before actually enabling optimal edge profiling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80667 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/Analysis/ProfileInfo.h | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) (limited to 'include/llvm/Analysis') diff --git a/include/llvm/Analysis/ProfileInfo.h b/include/llvm/Analysis/ProfileInfo.h index 16bfc13..94a8666 100644 --- a/include/llvm/Analysis/ProfileInfo.h +++ b/include/llvm/Analysis/ProfileInfo.h @@ -63,8 +63,13 @@ namespace llvm { // getFunction() - Returns the Function for an Edge, checking for validity. static const Function* getFunction(Edge e) { - assert(e.second && "Invalid ProfileInfo::Edge"); - return e.second->getParent(); + if (e.first) { + return e.first->getParent(); + } else if (e.second) { + return e.second->getParent(); + } + assert(0 && "Invalid ProfileInfo::Edge"); + return (const Function*)0; } // getEdge() - Creates an Edge from two BasicBlocks. -- cgit v1.1
