* avcodec/aacdec_fixed: Move fixed-point sinewin tables to its only userAndreas Rheinhardt2021-02-071-21/+12
| | | | | | | | | | | | | | | | | | | | | | The fixed-point AAC decoder is the only user of the fixed-point sinewin tables from sinewin; and it only uses a few of them (about 10% when counting by size). This means that guarding initializing these tables by an AVOnce (as done in 3719122065863f701026632f610175980d42b05a) is unnecessary for them. Furthermore the array of pointers to the individual arrays is also unneeded. Therefore this commit moves these tables directly into aacdec_fixed.c; this is done by ridding the original sinewin.h and sinewin_tablegen.h headers completely of any fixed-point code at the cost of a bit of duplicated code (the alternative is an ugly ifdef-mess). This saves about 58KB from the binary when using hardcoded tables (as these tables are hardcoded in this scenario); when not using hardcoded tables, most of these savings only affect the .bss segment, but the rest (< 1KB) contains relocations (i.e. savings in .data.rel.ro).

* avcodec/aacdec, sinewin: Move 120 and 960 point sine tables to aacdecAndreas Rheinhardt2020-12-081-4/+0
| | | | | | | | | | | | | The floating point AAC decoder is the only user of these tables, so it makes sense to move them there. Furthermore, initializing the ordinary power-of-two sinetables is currently not thread-safe and if the 120- and 960-point sinetables were not moved, one would have to choose whether to guard initializing these two tables with their own AVOnces or not. Doing so would add unnecessary AVOnces as the AAC decoder already guards initializing its static data by an AVOnce; not doing so would be fragile if a second user of these tables were to be added.

| | | | | | | | | | | | | | WMApro actually support 13-bits block sizes (potentially even up to 14), and thus we should support that also. If we get block sizes beyond what the decoder can handle (14 is possible depending on s->decode_flags), error out instead of crashing.
