Officially, we don't acknowledge non-default configurations of MXCSR, as getting there would require usage of the FENV_ACCESS pragma (at least insofar as rounding mode is concerned). We don't support the pragma, so we can assume that the default rounding mode - round to nearest, ties to even - is always used. However, it's inconsistent with the rest of the instruction set, where MXCSR is always effective (unless otherwise specified). Also, it's an unnecessary obstacle to the few brave souls that use fenv.h with LLVM. Avoid the hard-coded rounding mode for fp_to_f16; use MXCSR instead. llvm-svn: 259448 |

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 are writing a package for LLVM, see docs/Packaging.rst for our suggestions.
