From 913ff09a9acf563ae9719ff223bc117dd66ad6b0 Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Wed, 8 Aug 2012 01:10:31 +0000 Subject: Revert "Fix a quadratic algorithm in MachineBranchProbabilityInfo." It caused an assertion failure when compiling consumer-typeset. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161463 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/CodeGen/MachineBranchProbabilityInfo.h | 9 +++------ 1 file changed, 3 insertions(+), 6 deletions(-) (limited to 'include/llvm/CodeGen/MachineBranchProbabilityInfo.h') diff --git a/include/llvm/CodeGen/MachineBranchProbabilityInfo.h b/include/llvm/CodeGen/MachineBranchProbabilityInfo.h index 12189ceb7f..af4db7d6bd 100644 --- a/include/llvm/CodeGen/MachineBranchProbabilityInfo.h +++ b/include/llvm/CodeGen/MachineBranchProbabilityInfo.h @@ -16,12 +16,14 @@ #define LLVM_CODEGEN_MACHINEBRANCHPROBABILITYINFO_H #include "llvm/Pass.h" -#include "llvm/CodeGen/MachineBasicBlock.h" #include "llvm/Support/BranchProbability.h" #include namespace llvm { +class raw_ostream; +class MachineBasicBlock; + class MachineBranchProbabilityInfo : public ImmutablePass { virtual void anchor(); @@ -50,11 +52,6 @@ public: uint32_t getEdgeWeight(const MachineBasicBlock *Src, const MachineBasicBlock *Dst) const; - // Same thing, but using a const_succ_iterator from Src.
