2023-12-07Add HAS_SCALEARGBROWDOWNEVEN_RVV marco and disable it by defaultBruce Lai
HAS_SCALEARGBROWDOWNEVEN_RVV wasn't defined, so we cannot use ScaleARGBRowDownEven_RVV & ScaleARGBRowDownEvenBox_RVV. - Seperate to two conditional statements when selecting DownEven or DownEvenBox. - Also, add HAS_SCALEARGBROWDOWNEVEN_RVV and disable it by default.

2016-02-05rename MIPS_DSPR2 to DSPR2 for consistencyFrank Barchard
When attempting to normalize function names to end in Row_SIMD it was made harder with MIPS_DSPR2 naming convention. Other CPUs do not include the vendor. This should be named consistently. Removed the DISABLE_MIPS in favour of DISABLE_ASM for consistency with other processors. TBR=harryjin@google.com BUG=libyuv:562 Review URL: https://codereview.chromium.org/1677633002 .
2015-12-17Add rounding to InterpolateRow for improved quality and consistency.Frank Barchard
Remove inaccurate specializations for 1/4 and 3/4, since they round incorrectly. Specialize for 100% and 50% are kept due to performance. Make C and ARM code match SSSE3. Make unittests expect zero difference. BUG=libyuv:535 R=harryjin@google.com Review URL: https://codereview.chromium.org/1533643005 .

check from the calling code. This has 2 advantages - less code, and less overhead in calling function when any function is NOT used. Downside is more code for case where any is used.
