9c8a6ac85c configure: fix naming of some C++/cxx functions being mislabeled as cpp 2025-09-14 11:45:11 +00:00
Timo Rothenpieler
0ce413af9c configure: properly split C/CXX and CPP flags 
Right now, CFLAGS like -std=c17 leak onto the C++ compilers commandline,
leading to tons of warnings and even some errors.

Undefining __STRICT_ANSI__ causes strong warnings from the stdlib
headers. So only set it for C.

4c80cda08a forgejo: make aarch64 asm linter part of pre-commit 
Needed some minor semantical changes to the shell wrapper, since
pre-commit expects it to exit with an error when applying fixes.

edd1b93e53 forgejo: Check the aarch64 assembly indentation as part of the lint job 
Alternatively, this could be a separate job, potentially keyed
to only run on PRs that touch files matching */aarch64/*. But
as this runs very quickly, it's probably less clutter to just
bundle it here.

a3ce337926 tools: Add scripts for indenting and checking aarch64 assembly 
The same also applies for arm assembly, but there are more known
deviations within that.

Add a script which checks all files, except for a few known files
that deviate, for various reasons.

9ae42d42e6 avcodec/dvdsubdec: Don't return value != 0 on init success 
Currently, any nonnegative return value from an init function
is just treated as success and otherwise ignored; while it is
not explicitly forbidden to return something else than 0 (there
is no documentation whatsoever), the assumption is that
they return zero on success. So change dvdsubdec.c accordingly.

Also change dvdsub_parse_extradata() to return zero on success.

fbbb2996d5 vc1_parser: Reset unesc_index after extracting header with complete frames 
When PARSER_FLAG_COMPLETE_FRAMES is set (e.g. in Matroska),
unesc_index is not reset after the first frame, which causes
subsequent frames to inherit leftover header data.

This leads to incorrect keyframe marking and broken decoding.

f4b044bbe3 swscale: Disable avx2 hscale 8to15 on IceLake and below due to Intel Gather Data Sampling mitigation performance loss 
Intel provided a microcode update to mitigate this security
    vulnerability which has a huge negative performance impact on gather
    instructions. This means that hscale 8to15 avx2, which uses gather
    extensively, is no longer faster than SSSE3 on impacted CPUs.

1dcb0c6c3e avcodec/libjxldec: consume input on error 
libjxl consumes no input if it returns an error, so this loops over
and over while it spits out the same error many times. If we got an
error from libjxl and consumed no input, then we instead consume the
whole packet.

Since 9dc79241d9 we now always pop the
orientation off of the IFD and use a display matrix instead. This means
we should not produce a warning and refuse if the orientation field
indicates a default orientation (i.e. 1).
