* Prevent crash in drawhelper code when the cpu has MMXEXT but no SSE.Samuel Rødal2010-12-151-11/+0
| | | | | | | | | | We can't use the qdrawhelper_sse.cpp or qdrawhelper_sse3dnow.cpp when SSE is not run-time detected, as those are compiled with -msse and MMXEXT is just a subset of SSE. The compiler might choose to use an instruction not in the subset, causing a crash at run-time. Task-number: QTBUG-15693 Reviewed-by: Thiago Macieira

| | | | | | | | | | | Windows 64 does not support MMX with MSVC. This is a problem with the way SSE is currently used because it rely on previous vector instructions being available.

* Use NEON and preloading for 16 bit small / medium sized image blits.Samuel Rødal2010-09-011-0/+1
| | | | | | | | | | | | | | This gives a nice speedup for blitting of small and medium sized images by using preloading and avoiding function call overhead to memcpy for each scanline. For larger image widths memcpy becomes more efficient. Speedups of up to 40 % for 64 pixel wide images were measured. For image widths between 2 and 16 the speedup ranges between 12 % and 28 %.

* Undefined SSE symbols when crosscompiling Qt on PPC.Benjamin Poulain2010-08-311-1/+0
| | | | | | | | | | Qt does not build on PowerPC when compiling for both x86 and PPC on Mac. The compiler is invoked only once for both architecture so the defines are there in order to get the optimized path for x86. Those defines needs to be removed from the compilation environment when the target is set to PPC by GCC. Reviewed-by: Kent Hansen

* Implement the general blending of ARGB32_pm with SSSE3Benjamin Poulain2010-08-161-0/+11
| | | | | | | | | | | | | | | | | | | SSSE3 provides two tools to improve the blending speed over SSE2: -palignr -byte permutation The alignement is enforced on src and dst with palignr to always make aligned access. The extraction of the alpha mask is done with a byte permutation in order to save two instructions per cycle. On Atom, this patch gives between 0% (aligned src) to 10% of improvement (unaligned 4 and 12 bytes). On Core 2, this patch gives consistently 8% to 10% of improvement for every miss-alignment.

* Clean the CompositionFunction tables of drawhelperBenjamin Poulain2010-07-271-68/+59
| | | | | | | | | | | | | | | | Some instructions sets were defining partial table of composition functions. To work around that, qInitDrawhelperAsm() was resetting the composition function of QPainter::CompositionMode_Destination and anything above QPainter::CompositionMode_Xor. This was a problem because it makes it impossible to implement fast path for those composition mode. This patch export prototypes for the generic functions of each composition mode. The specialized implementations now define a complete table. Reviewed-by: Andreas Kling
