2018-11-27avutil/mem: Fix invalid use of av_alloc_sizeMark Harris
The alloc_size attribute is valid only on functions that return a pointer. GCC 9 (not yet released) warns about invalid usage: ./libavutil/mem.h:342:1: warning: 'alloc_size' attribute ignored on a function returning int' [-Wattributes] 342 | av_alloc_size(2, 3) int av_reallocp_array(void *ptr, size_t nmemb, size_t size); | ^~~~~~~~~~~~~ Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
2018-11-19avutil/mem: Correct documentation of av_fast_*alloc(z)Andreas Rheinhardt
The current wording regarding size and min_size is completely wrong and ignores that min_size is indeed only a desired minimal size, not the actually allocated size. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@googlemail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
2017-12-02avutil/mem: Add DECLARE_ASM_ALIGNED macro for DJGPP architecture.Thomas Köppe
The macro was added in 43171a2a738f5114768d34a7278e56e5fde714bc, but I forgot to add it to the DJGPP architecture in that change. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
2017-11-13Fix missing used attribute for inline assembly variablesThomas Köppe
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>

2017-04-26mem: uninline av_malloc(z)_array()Anton Khirnov
Inlining public functions hardcodes their implementation into the ABI, so it should be avoided unless there is a very good reason for it. No such reason exists in this case.

2016-08-23avutil/mem: remove av_realloc / av_malloc incompatibility warningMichael Niedermayer
memalign() is not guranteed to be compatible with free() or realloc() and for platforms in this category we have --enable-memalign-hack (which should be enabled automatically if such system is detected) Trying to somehow half support systems that can free() memalign memory but not reallocate it seems not worth the amount of work needed to keep 2 then incompatible allocation systems and ensure their seperation. That is unless this would affect a major platform on which we want to avoid the memalign hack code The warnings also cause wasted time and effort as people try to maintain a separation that does not exist currently.

2016-07-21libavutil: Always use some GCC style attributes on clangMartin Storsjö
Clang normally disguises as GCC (defining __GNUC__), and thus get all the normal GCC specific attributes. Clang can also work as a drop-in replacement for MSVC, and in these cases, it doesn't define __GNUC__, but defines _MSC_VER instead. Even in these setups, it still supports the GCC style attributes, thus use them, especially where there isn't any MSVC specific version, or where the MSVC specific version doesn't work on clang (for DECLARE_ASM_CONST).
