| | * Add unvectorized fallback in case FP exceptions are not maskedAllan Sandfeld Jensen2019-05-101-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an application enables FP exceptions our FP-based unpremul will raise the INVALID exception. Since disabling them locally might be slow just take a slow path when detected.

* Manually vectorize ARGB32toARGB32PM for SSE4.1 and NEONAllan Sandfeld Jensen2017-01-311-2/+53
| | | | | | | | | | | | Manually vectorizing is significantly faster because we can optimize for common cases like long stretches of opaque or transparent pixels. This is both smaller and faster than the auto-vectorized version, it is also much faster than the autovectorized version for AVX2 which then can be removed.

| | | | | | | | | | | Merges the SSE4 specific unpremultiply with the normal version, and adds a SSE2 fallback. There was no reason to split the two since compile time options will ensure the right version is inlined. Also adds short-cut for 0 and 255 values.

* Add AVX2 autovectorized versions of premultiplyAllan Sandfeld Jensen2015-03-101-0/+79
Following up on using GCC's autovectorizing for faster SSE4.1 premultiply, this patch adds specialized autovectorized versions of premultiply for AVX2, giving another almost doubling in speed. To make the speed up for AVX2 and also SSE4_1 available to non-GCC compilers, the target-specific methods have been moved to separate files.
