* swscale/x86/swscale: Remove unused ASM constantsAndreas Rheinhardt2021-02-24
| | | | | | | | | | | | | The last user of g15Mask, r15Mask, g16Mask and r16Mask was disabled in 77a416e8aab77058b542030870fd7178b62d2a62 and finally removed in 36e8de07ed62609df45d064b56501e3084d25723; b15Mask and b16Mask were apparently always unused (except for in_asm_used_var_warning_killer, a function that only existed to make the compiler not optimize ASM constants away). w10 is unused since d604bab901f6dfaaad672ef2164e42b1f350474c, w02 since ef423a661818f3c0d8206a2abbc65ff555cc0c67.

* swscale/rgb2rgb_template: use shuffle macro on big-endian archesAndriy Gelman2020-12-12
| | | | | | | | | | | | | | Fixes fate-qtrle-32bit on big-endian. The macro does a simple byte swap on uint8 array without any casts, so it's valid on big-endian arches. The mentioned test was failing because the byteswap function shuffle_bytes_3210_c() is used in the pixel format conversion (argb->bgra).

* swscale: arm: fix NEON hscale initJosh de Kock2020-05-15
| | | | | | | | | | | | | | | | | The NEON hscale function only supports X8 filter sizes and should only be selected when these are being used. At the moment filterAlign is set to 8 but in the future when extra NEON assembly for specific sizes is added they will need to have checks here too. The immediate usecase for this change is making the hscale checkasm test easier and without NEON specific edge-cases (x86 already has these guards). This applies the same fix from 718c8f9aa59751bb490e2688acf2b5cb68fd5ad1 on the 32 bit arm version of the function, fixing fate-checkasm-sw_scale there.

* swscale/vscale: Increase type strictnessAndreas Rheinhardt2020-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | libswscale/vscale.c makes extensive use of function pointers and in doing so it converts these function pointers to and from a pointer to void. Yet this is actually against the C standard: C90 only guarantees that one can convert a pointer to any incomplete type or object type to void* and back with the result comparing equal to the original which makes pointers to void generic pointers to incomplete or object type. Yet C90 lacks a generic function pointer type. C99 additionally guarantees that a pointer to a function of one type may be converted to a pointer to a function of another type with the result and the original comparing equal when converting back. This makes any function pointer type a generic function pointer type. Yet even this does not make pointers to void generic function pointers. Both GCC and Clang emit warnings for this when in pedantic mode. This commit fixes this by using a union that can hold one member of any of the required function pointer types to store the function pointer. This works even for C90.
