From cf0fe8d813727383d630055bb9d1cde21b00b7e7 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Mon, 5 Oct 2009 05:54:46 +0000 Subject: strength reduce a ton of type equality tests to check the typeid (Through the new predicates I added) instead of going through a context and doing a pointer comparison. Besides being cheaper, this allows a smart compiler to turn the if sequence into a switch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83297 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Bitcode/Writer/BitcodeWriter.cpp | 8 +++----- 1 file changed, 3 insertions(+), 5 deletions(-) (limited to 'lib/Bitcode/Writer/BitcodeWriter.cpp') diff --git a/lib/Bitcode/Writer/BitcodeWriter.cpp b/lib/Bitcode/Writer/BitcodeWriter.cpp index 5857c5914b..ae269dfbcc 100644 --- a/lib/Bitcode/Writer/BitcodeWriter.cpp +++ b/lib/Bitcode/Writer/BitcodeWriter.cpp @@ -729,18 +729,16 @@ static void WriteConstants(unsigned FirstVal, unsigned LastVal, } else if (const ConstantFP *CFP = dyn_cast(C)) { Code = bitc::CST_CODE_FLOAT; const Type *Ty = CFP->getType(); - if (Ty == Type::getFloatTy(Ty->getContext()) || - Ty == Type::getDoubleTy(Ty->getContext())) { + if (Ty->isFloatTy() || Ty->isDoubleTy()) { Record.push_back(CFP->getValueAPF().bitcastToAPInt().getZExtValue()); - } else if (Ty == Type::getX86_FP80Ty(Ty->getContext())) { + } else if (Ty->isX86_FP80Ty()) { // api needed to prevent premature destruction // bits are not in the same order as a normal i80 APInt, compensate.
