* 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.

* Make qt_memfill{16,32} unconditionalThiago Macieira2014-01-161-1/+1
| | | | | | | | | | | | | These two functions used to cause a runtime detection of the CPU features in order to improve their performance. Since the last two commits, there's no runtime detection of either SSE2 or Neon support, so there's no point in attempting runtime detection.

* Overhaul the qsimd_p.h: rename macros and update conditionalsThiago Macieira2012-05-311-2/+2
| | | | | | | | | | | | | | | 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). So we only use the intrinsics when the compiler was instructed to generate code for that instruction set anyway.
