Paul E. Murphy f38a61c66d fast_math: implement optimized PPC routines ... Implement cvRound using inline asm. No compiler support exists today to properly optimize this. This results in about a 4x speedup over the default rounding. Likewise, simplify the growing number of rounding function overloads. For P9 enabled targets, utilize the classification testing instruction to test for Inf/Nan values. Operation speedup is about 1.2x for FP32, and 1.5x for FP64 operands. For P8 targets, fallback to the GCC nan inline. It provides a 1.1/1.4x improvement for FP32/FP64 arguments.		2019-08-07 15:01:18 -05:00
