* swscale: aarch64: Fix yuv2rgb with negative stridesrelease/3.2Martin Storsjö2022-11-041-4/+4
| | | | | | | | | | | | | | | | Treat the 32 bit stride registers as signed. Alternatively, we could make the stride arguments ptrdiff_t instead of int, and changing all of the assembly to operate on these registers with their full 64 bit width, but that's a much larger and more intrusive change (and risks missing some operation, which would clamp the intermediates to 32 bit still).

* libswcale: Fix possible string overflow in test.Adam Richter2019-05-131-2/+2
| | | | | | | | | | | | | In libswcale/tests/swcale.c, the function fileTest() calls sscanf in an argument of "%12s" on character srcStr[] and dstStr[], which are only 12 bytes. So, if the input string is 12 characters, a terminating null byte can be written past the end of these arrays. This bug was found by cppcheck.

* swscale: save ebx register when it is not availableAndreas Cadhalpun2017-01-261-10/+10
| | | | | | | | | | | | | | | | Configure checks if the ebx register can be used for asm and it has to be saved if and only if this is not the case. Without this the build fails when configuring with --toolchain=hardened --disable-pic on i386 using gcc 4.8: error: PIC register clobbered by '%ebx' in 'asm' In that case gcc 4.8 reserves the ebx register for the GOT needed for PIE, so it can't be used in asm directly.
