Andreas Rheinhardt	ed33bbe678	avcodec/mpegaudiodec: Hardcode tables to save space 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>	4 years ago
Vicente Olivert Riera	ad16eff64b	mips: add support for R6 Understanding the mips32r6 and mips64r6 ISAs in the configure script is not enough. In order to have full support for MIPS R6 in FFmpeg we need to be able to build it, and for that we need to make sure we don't use incompatible assembler code which makes the build fail. Ifdefing the offending code is sufficient to fix the problem. Signed-off-by: Vicente Olivert Riera <Vincent.Riera@imgtec.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
James Cowgill	157d6f0d5b	mips: port optimizations to mips n64 This mainly consists of replacing all the pointer arithmatic 'addiu' instructions with PTR_ADDIU which will handle the differences in pointer sizes when compiled on 64 bit mips systems. The header asmdefs.h contains the PTR_ macros which expend to the correct mips instructions to manipulate registers containing pointers.
