* Use Q_DECL_VECTORCALL in a few more placesThiago Macieira2018-12-111-16/+16
| | | | | | | | | | | There were a few functions that passed vectors in parameters but did not mark as vectorcall. I've taken the opportunity to de-macroify one macro, but I'm not going to do it for the rest.

* Add AVX2 versions of qt_memfill32 and qt_memfill64Thiago Macieira2018-12-111-2/+4
| | | | | | | | | | The implementation is almost the same 4-way-unrolled loop, but because of the wider registers, we fill 128 bytes per loop. Unlike the SSE2 implementation, the AVX2 version uses unaligned stores and won't try to align in the prologue, matching glibc's __memset_avx2 (also unaligned).

* Move qt_memfill32-based implementation of qt_memfill16 to genericThiago Macieira2018-11-111-23/+0
| | | | | | | | | | The SSE2 implementation and the one in qdrawhelper.cpp are almost identical. And if we make it so qt_memfill16 can tail-call to qt_memfill32, there's no need for inlining, so there's no need to keep it in qdrawhelper_sse2.cpp Change-Id: I343f2beed55440a7ac0bfffd15637027771c2254 Reviewed-by: Allan Sandfeld Jensen <allan.jensen@qt.io>

Now the alpha value is properly ignored, which is both more correct and faster. This also makes SSE2 and AVX2 implementations match NEON which was already doing the right thing (though had dead code for doing it wrong).

* Avoid out of bounds memory reads when scaling imagesLars Knoll2014-03-281-3/+11
| | | | | | | | | | | | | | | | 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.

| * Fix drawCachedGlyphs on RGBA8888Allan Sandfeld Jensen2014-02-261-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | drawCachedGlyphs draws with the wrong color on RGBA8888. The issue is that the draw routines bitmapblit_quint32 and alphamapblit_quint32 while safe to use on rgba formats, needs to have the input color converted. This patch adds small wrapper functions for bitmapblit and alphamapblit that converts the formats. Two tests are extended to ensure we have test coverage.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Benchmarking shows it took up to 3.5% of Qt Creator's initialization cost. Optimize by modifying only one variable per loop: instead of updating n and dst128, we only update one variable at a time. Removing the Duff's Device also improves the code, since the compiler won't try to update dst128 four times per loop, only once. The moving of the epilogue close to the prologue was just to make the code a little cleaner.

| | | | | | | | | | | | | | | 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.

* Remove the old code using MMX registers.Thiago Macieira2012-03-281-2/+2
| | | | | | | | | | | | | | | | | | | There are only 8 MMX registers, each 64-bit wide, and they alias the x87 registers. The access to the MMX register cannot use the new VEX-prefix instructions either. All of the functions being replaced are either present in the qdrawhelper_sse2.cpp and qdrawhelper_ssse3.cpp files, or the plain C++ function in qdrawhelper.cpp is vectorised when compiled with -ftree-vectorize (enabled in -O3), if SSE2 support is enabled. All x86-64 processors have SSE2, so this is a net improvement for 64-bit builds. For 32-bit builds, without further support this will cause the code to use non-vector or x87 instructions, which aren't the best. The solution will come in another commit.
