> The following patchset refactors the AAC decoder step by step,
> removing all large-scale templating and abstracting away typed
> DSP functions from symbol parsing.
>
> This series saves 110Kib of binary data from libavcodec.so
> when compiled with Clang 18 with -O3, after stripping.
>
> The patchset can also be viewed here:
> https://github.com/cyanreg/FFmpeg/tree/aac_cleanup
>
> Fate passes on each step, and I've been running this patchset for
> a week with no issues.
>
> This also prepares the decoder for USAC support.

I've rebased the linked repo to current git master if anyone
wants to test.
