54 - Reported problem with use of (missing) scalefactor index 63.
56 Felix von Leitner <felix-mad@fefe.de>
58 - Suggested Intel scaling alternative for possible speedup.
60 Andre McCurdy <armccurdy@yahoo.co.uk>
61 2000/08/10: imdct_l_arm.S
62 - ARM optimized assembly replacement for III_imdct_l().
63 2000/09/15: imdct_l_arm.S
64 - Applied Nicolas Pitre's rounding optimisation in all remaining
67 - Inspiration for Huffman decoding and requantization rewrite, and
69 2001/03/24: imdct_l_arm.S
70 - Corrected PIC unsafe code.
72 - Discovered bug in ARM version of mad_f_scale64().
74 Haruhiko OGASAWARA <theta@m1.interq.or.jp>
76 - Reported discrepancy in alias reduction for mixed short blocks.
78 Brett Paterson <brett@fmod.org>
80 - Reported missing <assert.h> et al. under MS Embedded Visual C.
82 Sean 'Shaleh' Perry <shaleh@via.net>
84 - Suggested use of size-dependent typedefs.
85 2001/10/22: config.guess, config.sub
86 - Keep up to date for proper Debian packaging.
88 Bertrand Petit <eemad@phoe.frmug.org>
90 - Suggested PCM channel enumeration constants.
92 - Suggested MAD_ERROR_NONE enumeration constant.
94 - Suggested mad_stream_errorstr() function.
96 Nicolas Pitre <nico@cam.org>
98 - Parameterized all scaling for correct use of all multiplication
99 methods within mad_synth_frame().
100 - Rewrote the FPM_ARM version of mad_f_mul() so we have 64-bit
101 multiplication result, rounding and scaling with 3 instructions.
102 2000/09/09: imdct_l_arm.S
103 - Optimized rounding + scaling operations.
105 - Changed D[] run-time shifts to compile-time.
106 - Modified synthesis for better multiply/accumulate code output.
107 2001/08/11: fixed.h, synth.c
108 - Suggested 64-bit FPM negation and negative term factorization
111 - Suggested unrounded behavior for FPM_DEFAULT when OPT_SPEED.
113 - Suggested computation of any resampling ratio.
