From 257464a07272a74b772d03fca31617cd3a1826db Mon Sep 17 00:00:00 2001 From: Evan Cheng Date: Fri, 5 Jan 2007 23:31:08 +0000 Subject: [PATCH] - Remove isSetCCExpensive() etc. These are no longer used. - Add isSelectExpensive() etc. It's used to tell codegen that select is expensive for a given target, avoid using it if possible. Currently it's only used to expand FCOPYSIGN. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32939 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/Target/TargetLowering.h | 18 ++++++++---------- 1 file changed, 8 insertions(+), 10 deletions(-) diff --git a/include/llvm/Target/TargetLowering.h b/include/llvm/Target/TargetLowering.h index 2a353ba7e96..0f481bbf191 100644 --- a/include/llvm/Target/TargetLowering.h +++ b/include/llvm/Target/TargetLowering.h @@ -89,9 +89,9 @@ public: /// codegen. bool usesGlobalOffsetTable() const { return UsesGlobalOffsetTable; } - /// isSetCCExpensive - Return true if the setcc operation is expensive for + /// isSelectExpensive - Return true if the select operation is expensive for /// this target. - bool isSetCCExpensive() const { return SetCCIsExpensive; } + bool isSelectExpensive() const { return SelectIsExpensive; } /// isIntDivCheap() - Return true if integer divide is usually cheaper than /// a sequence of several shifts, adds, and multiplies for this target. @@ -608,10 +608,9 @@ protected: StackPointerRegisterToSaveRestore = R; } - /// setSetCCIxExpensive - This is a short term hack for targets that codegen - /// setcc as a conditional branch.
