* Manually vectorize ARGB32toARGB32PM for SSE4.1 and NEONAllan Sandfeld Jensen2017-01-311-0/+61
| | | | | | | | | | | | 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.

* Avoid out of bounds memory reads when scaling imagesLars Knoll2014-03-281-6/+6
| | | | | | | | | | | | | | | | The calculation of the width/height required for the scaling algorithm was prone to floating point rounding issues, where the lower value got rounded down, the higher one rounded up. This could lead to a situation where we iterated over one more line/pixel in the line than we have in the source image. Correct this by passing the dimension of the source image into the function and bounds checking the values before iterating.

| | | | | | | | | | | | | | | The QT_HAVE_xxx macros are replaced with QT_COMPILER_SUPPORTS_xxx. They indicate that the compiler supports those intrinsics, but not necessarily that they can be used right now. ICC and MSVC allow one to use the intrinsics anywhere, but for Qt all uses of the intrinsics are either in specially-built files, protected by runtime checks, or they are unconditional (qstring.cpp).
