* avcodec/cabac: Move encoder related stuff to libavcodec/tests/cabac.cAndreas Rheinhardt2021-02-02
| | | | | | | (This is actually the second time the encoder stuff is removed; the first was in 8b4119187b62d6932e07aded11d33d3b24e1b42f.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* Fix missing used attribute for inline assembly variablesThomas Köppe2017-11-13
| | | | | | | | | | | | | Variables used in inline assembly need to be marked with attribute((used)). Static constants already were, via the define of DECLARE_ASM_CONST. But DECLARE_ALIGNED does not add this attribute, and some of the variables defined with it are const only used in inline assembly, and therefore appeared dead. This change adds a macro DECLARE_ASM_ALIGNED that marks variables as used. This change makes FFMPEG work with Clang's ThinLTO. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

| | | | | | | | | | | | | | | | | | | | | | | | | | The reason is this is easier for PIC code (in particular on darwin...). Keep the old names as pointers (static in cabac_functions.h so gcc knows these are just immediate offsets) so the c code can nicely stay the same (alternatively could use offsets directly in the functions needing the tables). This should produce the same code as before with non-pic and better code (confirmed) with pic. The assembly uses the new table but still won't work for PIC case. Signed-off-by: Ronald S.

| * cabac: split cabac.h into declarations and function definitionsDiego Biurrun2012-01-12
| | | | | | | | | | | | | | | | | | | | | | This fixes standalone compilation of some decoders with --disable-optimizations. cabac.h defines some inline functions that use symbols from cabac.c. Without optimizations these inline functions are not eliminated and linking fails with references to non-existing symbols. Splitting the inline functions off into their own header and only #including it in the places where the inline functions are used allows #including cabac.h from anywhere without ill effects.
