* ``the value cannot fit within the destination type`` is ambiguous. It could mean overflow, underflow (not in the IEEE-754 sense) or a result that cannot be exactly represented and requires rounding or it could mean some combination of these. The semantics now state it means overflow **only**. * Using "truncation" in the semantics is very misleading given that it doesn't necessarily truncate (i.e. round to zero). For example on x86_64 with SSE2 this is currently mapped to cvtsd2ss instruction who's rounding behaviour is dependent on the MXCSR register which is usually set to round to nearest even by default. The semantics now state that the rounding mode is undefined. llvm-svn: 246792 |

Low Level Virtual Machine (LLVM) ================================ This directory and its subdirectories contain source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and runtime environments. LLVM is open source software. You may freely distribute it under the terms of the license agreement found in LICENSE.txt. Please see the documentation provided in docs/ for further assistance with LLVM, and in particular docs/GettingStarted.rst for getting started with LLVM and docs/README.txt for an overview of LLVM's documentation setup. If you're writing a package for LLVM, see docs/Packaging.rst for our suggestions.
