* avcodec/mpegaudiodec: Hardcode tables to save spaceAndreas Rheinhardt2020-12-08
| | | | | | | | | | | | | | | | | | | The csa_tables (which always consist of 32 entries of four byte each, but the type depends upon whether the decoder is fixed or floating-point) are currently initialized once during decoder initialization; yet it turns out that this is actually no benefit: The code used to initialize these tables takes up 153 (fixed point) and 122 (floating point) bytes when compiled with GCC 9.3 with -O3 on x64, so it is better to just hardcode these tables. Essentially the same applies to the is_tables: They have a size of 128B each and the code to initialize them occupies 149 (fixed point) resp. 140 (floating point) bytes. So hardcode them, too. To make the origin of the tables clear, references to the code used to create them have been added. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/fft_template, fft_init_table: Make ff_fft_init() thread-safeAndreas Rheinhardt2020-11-24
| | | | | | | | | | | | | | | | | | | | | | | | Commit 1af615683e4a1a858407afbaa2fd686842da7e49 put initializing the ff_fft_offsets_lut (which is typically used if FFT_FIXED_32) behind an ff_thread_once() to make ff_fft_init() thread-safe; yet there is a second place where said table may be initialized which is not guarded by this AVOnce: ff_fft_init_mips(). MIPS uses this LUT even for ordinary floating point FFTs, so that ff_fft_init() is not thread-safe (on MIPS) for both 32bit fixed-point as well as floating-point FFTs; e.g. ff_mdct_init() inherits this flaw and therefore initializing e.g. the AAC decoders is not thread-safe (on MIPS) despite them having FF_CODEC_CAP_INIT_CLEANUP set. This commit fixes this by moving the AVOnce to fft_init_table.c and using it to guard all initializations of ff_fft_offsets_lut. (It is not that bad in practice, because every entry of ff_fft_offsets_lut is never read during initialization and is only once ever written to (namely to its final value); but even these are conflicting actions which are (by definition) data races and lead to undefined behaviour.)

| | | | | | | | | | | | | | | | To enable runtime detection for MIPS, we need to refine ffbuild part to support buildding these feature together.

Secondly, we compile MMI and MSA C sources with their own flags to ensure their flags won't pollute the whole program and generate illegal code.

* avcodec/mips: [loongson] refine process of setting block as 0 in h264dsp_mmi.Shiyou Yin2019-07-28
| | | | | | | | | | | | | | | | | | | | | | In function ff_h264_add_pixels4_8_mmi, there is no need to reset '%[ftmp0]' to 0, because it's value has never changed since the start of the asm block. This patch remove the redundant 'xor' and set src to zero once it was loaded. In function ff_h264_idct_add_8_mmi, 'block' is seted to zero twice. This patch removed the first setting zero operation and move the second one after the load operation of block. In function ff_h264_idct8_add_8_mmi, 'block' is seted to zero twice too. This patch just removed the second setting zero operation. This patch mainly simplifies the implementation of functions above, the effect on the performance of whole h264 decoding process is not obvious. According to the perf data, proportion of ff_h264_idct_add_8_mmi decreased from 0.29% to 0.26% and ff_h264_idct8_add_8_mmi decreased from 0.62% to 0.59% when decoding H264 format on loongson 3A3000(For reference only , not very stable.).
