* 3DNow! support by KIMURA Takuhiro *
* *
* (http://hannah.ipc.miyakyo-u.ac.jp/kim/) *
* Syuuhei Kashiyama *

-----------------------------
What's new in patch for 0.59r
-----------------------------
- 3DNow! optimized decode routine (decode_3dnow.s,dct36_3dnow.s ;
these code based Syuuhei Kashiyama's 3DNow! patch for mpg123-0.59o)
- 3DNow! optimized equalizer (equalizer_3dnow.s ; do_equalizer() only)
- target "linux-3dnow-alsa" "linux-3dnow-esd" added (untested)
- automatic detect 3DNow! support CPU from CPUFLAGS (getcpuflags.s)
(i.e. use floating-pointer decode routine if your CPU isn't support
3DNow! or MMX instructions)
-------------
Added options
-------------
"--test-3dnow" : display result of autodetect and exit
"--force-3dnow" : force use of 3DNow! optimized decoder
(it will cause SIGILL if your CPU isn't support 3DNow! or MMX
instructions)
"--no-3dnow" : force use of floating-pointer decoder
-----------
How to make
-----------
[1] To make 3DNow! optimized mpg123,you need binutils-2.9.1.0.15 or later.
You can find the most recent binutils (2.9.1.0.25 until 23.Jun.1999) at
- kernel.org (and mirrors) : /pub/linux/devel/gcc/
- http://hannah.ipc.miyakyo-u.ac.jp/kim/Linux/binutils/
(Takuhiro's local copy)
etc.
[2] Type "make linux-3dnow" (OSS)
or "make linux-3dnow-alsa" (ALSA).
[3] Enjoy!
