From 0a29cb045444c13160e90fe7942a9d7c720185ed Mon Sep 17 00:00:00 2001 From: Tim Northover Date: Tue, 22 Jan 2013 09:46:31 +0000 Subject: Make APFloat constructor require explicit semantics. Previously we tried to infer it from the bit width size, with an added IsIEEE argument for the PPC/IEEE 128-bit case, which had a default value. This default value allowed bugs to creep in, where it was inappropriate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173138 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/AsmParser/LLLexer.cpp | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) (limited to 'lib/AsmParser') diff --git a/lib/AsmParser/LLLexer.cpp b/lib/AsmParser/LLLexer.cpp index 925f9bc..2efa1f0 100644 --- a/lib/AsmParser/LLLexer.cpp +++ b/lib/AsmParser/LLLexer.cpp @@ -713,20 +713,21 @@ lltok::Kind LLLexer::Lex0x() { case 'K': // F80HexFPConstant - x87 long double in hexadecimal format (10 bytes) FP80HexToIntPair(TokStart+3, CurPtr, Pair); - APFloatVal = APFloat(APInt(80, Pair)); + APFloatVal = APFloat(APFloat::x87DoubleExtended, APInt(80, Pair)); return lltok::APFloat; case 'L': // F128HexFPConstant - IEEE 128-bit in hexadecimal format (16 bytes) HexToIntPair(TokStart+3, CurPtr, Pair); - APFloatVal = APFloat(APInt(128, Pair), true); + APFloatVal = APFloat(APFloat::IEEEquad, APInt(128, Pair)); return lltok::APFloat; case 'M': // PPC128HexFPConstant - PowerPC 128-bit in hexadecimal format (16 bytes) HexToIntPair(TokStart+3, CurPtr, Pair); - APFloatVal = APFloat(APInt(128, Pair)); + APFloatVal = APFloat(APFloat::PPCDoubleDouble, APInt(128, Pair)); return lltok::APFloat; case 'H': - APFloatVal = APFloat(APInt(16,HexIntToVal(TokStart+3, CurPtr))); + APFloatVal = APFloat(APFloat::IEEEhalf, + APInt(16,HexIntToVal(TokStart+3, CurPtr))); return lltok::APFloat; } } -- cgit v1.1
