Tom Stellard	2ef5ec6b2b	Fix implementation of sqrt v2 ... Passing values less than 0 to the llvm.sqrt() intrinsic results in undefined behavior, so we need to check the input and return NaN if is is less than 0. v2: - Fix build failures. llvm-svn: 241906	2015-07-10 13:37:07 +00:00

Tom Stellard	6c7b86c106	Implement nextafter() builtin ... There are two implementations of nextafter(): 1. Using clang's __builtin_nextafter. Clang replaces this builtin with a call to nextafter which is part of libm. Therefore, this implementation will only work for targets with an implementation of libm (e.g. most CPU targets). 2. The other implementation is written in OpenCL C. This function is known internally as __clc_nextafter and can be used by targets that don't have access to libm. llvm-svn: 192383	2013-10-10 19:08:51 +00:00
