From faa1471ffcc1bbffe3a9d3d1f4b5fe3adbef647a Mon Sep 17 00:00:00 2001 From: "Ronald S. Bultje" Date: Sat, 28 Jun 2014 11:05:52 -0400 Subject: swr: rewrite resample_common/linear_float_sse/avx in yasm. Linear interpolation goes from 63 (llvm) or 58 (gcc) to 48 (yasm) cycles/sample on 64bit, or from 66 (llvm/gcc) to 52 (yasm) cycles/ sample on 32bit. Bon-linear goes from 43 (llvm) or 38 (gcc) to 32 (yasm) cycles/sample on 64bit, or from 46 (llvm) or 44 (gcc) to 38 (yasm) cycles/sample on 32bit (all testing on OSX 10.9.2, llvm 5.1 and gcc 4.8/9).
