|
10 for building mpg123 with one optimization only, you have to choose exclusively between
|
|
11 OPT_GENERIC (generic C code for everyone)
|
|
12 OPT_I386 (Intel i386)
|
|
13 OPT_I486 (...)
|
|
14 OPT_I586 (Intel Pentium)
|
|
15 OPT_I586_DITHER (Intel Pentium with dithering/noise shaping for enhanced quality)
|
|
16 OPT_MMX (Intel Pentium and compatibles with MMX, fast, but not the best accuracy)
|
|
17 OPT_3DNOW (AMD 3DNow!, K6-2/3, Athlon, compatibles...)
|
|
18 OPT_ALTIVEC (Motorola/IBM PPC with AltiVec under MacOSX)
|
|
19
|
|
20 or you define OPT_MULTI and give a combination which makes sense (do not include i486, do not mix altivec and x86).
|
|
21
|
|
22 I still have to examine the dynamics of this here together with REAL_IS_FIXED.
