* Move supprt-arm.S to separate library.Thomas Martitz2012-01-21
| | | | | | | Core, codecs and plugins link it separately so this gets rid of SOURCES trickery. Don't build it for hosted targets. Change-Id: If15ef90e93cd218a4352ae8e89eea95d3122452f
* FS#12141 by Sean BartellNils Wallménius2011-06-02
| | | | | | | | | | | Some of these were found with http://www.samba.org/junkcode/#findstatic. Changes of note: * The old MDCT has been removed. * Makefile.test files that create test programs for libatrac, libcook, and libffmpegFLAC have been removed, as they don't work. My project will have a replacement that works with all codecs. * I've tried not to remove anything useful. CLIP_TO_15 was removed from libtremor because there's another copy (also commented) in codeclib. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29945 a1c6a512-1295-4272-9138-f99709370657

| | | | | | ffmpeg_bitstream.c as a part of the codec lib. Use this codeclib implementation in libffmpegFLAC. Implement adapted version of the unaligned longword reading optimization for coldfire from the libwma version of this code. Speeds up cook decoding by 2-3% on h300 and flac by 25% on h300, also speeds up flac decoding by 2% on c200 (decoding speed of cook on c200 is unchanged). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27430 a1c6a512-1295-4272-9138-f99709370657

| | | | | | | | | | | #if (CONFIG_PLATFORM & PLATFORM_HOSTED) (or equivalently). The simulator defines PLATFORM_HOSTED, as RaaA will do (RaaA will not define SIMULATOR).

* Improvements to specialized dividers for APE codec:Andrew Mahone2010-01-28
| | | | | | | | | * Use Newton-Raphson divider on ARMv5e and ARMv6, about 7% speedup on Gigabeat S. * On ARMv4 targets using IRAM, remove insane filter buffer from IRAM, fill available IRAM with LUT of reciprocals for small divisors - speedup varies according to target and available IRAM, APE normal sample is approx. 109% RT on e200. * Rename apps/codecs/lib/udiv32_armv4.S to apps/codecs/lib/udiv32_arm.S, which includes dividers for all ARM targets specialized for APE. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24354 a1c6a512-1295-4272-9138-f99709370657

WMA and Vorbis should have no functional changes since they already used this code. Further optimization is possible and would benefit all 3 codecs. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18412 a1c6a512-1295-4272-9138-f99709370657
