| 2 | decode_sse3d: Synth for SSE and extended 3DNow (yeah, the name is a relic) |
||
| 3 | |||
| 4 | copyright 2006-2007 by Zuxy Meng/the mpg123 project - free software under the terms of the LGPL 2.1 |
||
| 5 | see COPYING and AUTHORS files in distribution or http://mpg123.org |
||
| 6 | initially written by the mysterious higway for MMX (apparently) |
||
| 7 | then developed into SSE opt by Zuxy Meng, also building on Romain Dolbeau's AltiVec |
||
| 8 | Both have agreed to distribution under LGPL 2.1 . |
||
| 9 | |||
| 10 | Transformed back into standalone asm, with help of |
||
| 11 | gcc -S -DHAVE_CONFIG_H -I. -march=pentium -O3 -Wall -pedantic -fno-strict-aliasing -DREAL_IS_FLOAT -c -o decode_mmxsse.{S,c} |
||
| 12 | |||
| 13 | The difference between SSE and 3DNowExt is the dct64 function and the synth function name. |
||
| 14 | This template here uses the SYNTH_NAME and MPL_DCT64 macros for this - see decode_sse.S and decode_3dnowext.S... |
||
| 15 | That's not memory efficient since there's doubled code, but it's easier than giving another function pointer. |
||
| 16 | Maybe I'll change it in future, but now I need something that works. |
