661c1b6641 Merge "windows exports: use dllexport attribute, instead of visibility." into main 2024-03-06 23:54:57 +00:00

8487860a8c windows exports: use dllexport attribute, instead of visibility. 
With older toolchains, at the least, visibility attributes don't
work and all symbols are exported along with lots of unsupported
warnings.

8ea678b990 webp/mux.h: data lifetime note w/copy_data=0 
The data mostly must persist until a call to Assemble() is made. If the
data is discarded and subsequent calls are made the behavior is
undefined.

4723db65bc cosmetics: s/SANITY_CHECK/DCHECK/ 
'sanity' is not an inclusive term. This is a debug check so DCHECK
better shows the intent.

f4b9bc9ea1 clear -Wextra-semi-stmt warnings 
This is available with clang. Clears warnings of the form:
  warning: empty expression statement has no effect; remove unnecessary
    ';' to silence this warning [-Wextra-semi-stmt]

As a side-effect it also clear a few -Wpedantic warnings with gcc:
  warning: ISO C does not allow extra ';' outside of a function
    [-Wpedantic]

cbe825e4cc cmake: fix sharpyuv simd files' build 
Without this, when targeting x86, the compiler may not enable sse2
by default without -msse2 switch and therefore leaves WEBP_USE_SSE2
undefined and the SSE2 procedure won't be built.

d7a0506dcc Add YUV420 riskiness metric. 
Basic version for 8 bit only and C only (no simd).

Hidden behind a compile flag because the precompiled table is
fairly large (114kiB) and more than triples the size of the library.
