From: Chris Lattner Date: Tue, 19 Aug 2008 04:26:57 +0000 (+0000) Subject: Reid had to call this class "slot machine" out of some strange reference X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=0d9574a1cd68c6e41f725c22657b8bb3f8d74117;p=oota-llvm.git Reid had to call this class "slot machine" out of some strange reference to the gambling device. Name it something more meaningful. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54974 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/lib/VMCore/AsmWriter.cpp b/lib/VMCore/AsmWriter.cpp index 93b69b913e9..ccc793f36e0 100644 --- a/lib/VMCore/AsmWriter.cpp +++ b/lib/VMCore/AsmWriter.cpp @@ -44,7 +44,7 @@ AssemblyAnnotationWriter::~AssemblyAnnotationWriter() {} /// This class provides computation of slot numbers for LLVM Assembly writing. /// -class SlotMachine { +class SlotTracker { public: /// ValueMap - A mapping of Values to slot numbers typedef DenseMap ValueMap; @@ -67,24 +67,24 @@ private: public: /// Construct from a module - explicit SlotMachine(const Module *M); + explicit SlotTracker(const Module *M); /// Construct from a function, starting out in incorp state. - explicit SlotMachine(const Function *F); + explicit SlotTracker(const Function *F); /// Return the slot number of the specified value in it's type - /// plane.
