Tom Stellard a64bad8338 Use a more accurate implementation for exp ... Using exp2(x * M_LOG2E_F) does not give us accurate enough results for OpenCL. If you look at the new exp implementation you'll see that it does multiply the input by M_LOG2E_F, but it still uses the original input in part of the calculation. This exp implementation was ported from the AMD builtin library and has been tested with piglit, OpenCV, and the ocl conformance tests. llvm-svn: 237229		2015-05-13 03:55:09 +00:00
