From bdad80977b40ce9a833b2373323a5949dd2e5332 Mon Sep 17 00:00:00 2001 From: Dale Johannesen Date: Thu, 9 Aug 2007 22:51:36 +0000 Subject: Patch 10 for long double. Doing constants right needs expanding ConstantFP to handle values bigger than double. If we assume host==target and host long double works correctly, this is not too bad, but we don't want to have that limitation longterm. I could implement accepting double constants as long double or something like that, which would lead to incorrect codegen with no errors; the more I think about that the worse it seems. Rather than do such a hack that would be backed out later, I'm settling for giving reasonable error messages, for now. llvm-svn: 40974 --- llvm/lib/Bitcode/Reader/BitcodeReader.cpp | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'llvm/lib/Bitcode/Reader/BitcodeReader.cpp') diff --git a/llvm/lib/Bitcode/Reader/BitcodeReader.cpp b/llvm/lib/Bitcode/Reader/BitcodeReader.cpp index 07a4279..eb18e31 100644 --- a/llvm/lib/Bitcode/Reader/BitcodeReader.cpp +++ b/llvm/lib/Bitcode/Reader/BitcodeReader.cpp @@ -629,6 +629,10 @@ bool BitcodeReader::ParseConstants() { V = ConstantFP::get(CurTy, BitsToFloat(Record[0])); else if (CurTy == Type::DoubleTy) V = ConstantFP::get(CurTy, BitsToDouble(Record[0])); + // FIXME: Make long double constants work. + else if (CurTy == Type::X86_FP80Ty || + CurTy == Type::FP128Ty || CurTy == Type::PPC_FP128Ty) + assert(0 && "Long double constants not handled yet."); else V = UndefValue::get(CurTy); break; -- cgit v1.1
