* tst_qlocale: improve failure message in tst_QLocale::macDefaultLocaleRohan McGovern2011-03-281-1/+5
| | | | | | Use QVERIFY2 to output more details about this failure. Reviewed-by: Toby Tomkins
* Add a once-over unrolled fromLatin1 conversion (32 characters)Thiago Macieira2011-03-271-0/+46
| | | | | This was suggested by Matthias Kretz on my blog. It improves on GCC (one case up to 5%), but worsens on ICC (up to 5%).

| * QDir: Fix absolute paths when using file enginesJoão Abecasis2011-03-181-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | QFileSystemEntry doesn't know about paths as implemented by custom file engines, such as is the case with resource files. In such cases, we need to allow the engine to make the relative to absolute conversion. Expanded QDir's test case to ensure resource paths are considered in more places.

| * | Add ARM Neon versions of fromLatin1 and fromUtf8Thiago Macieira2011-03-221-0/+192
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fromLatin1 code is very simple, yet the handwritten assembly performs better due to the use of post-increments. The fromUtf8 code has two alternatives. Neon lacks an instruction similar to SSE2's _mm_movemask_epi8 (PMOVMSKB) which extracts one bit from each byte and stores it in a register. We used that in the UTF-8 code to detect bytes with the highest bit set. To compensate, we used two alternatives: 1) AND the comparison result with a vector containing {128, 64, ...,1 } Do 3 parallel-adds (VPADD.I8), which will make the mask propagate to the lowest component in the vector. Trick found in: http://hilbert-space.de/?p=22 (comment 16-17) 2) Extract the two words from the doubleword Neon register and do the work in ARM assembly. It looks like the latter version is performing better.

| | | | | | | | | | | | | | | This assumes that there are no overlong sequences, no continuation characters without the leading, no missing continuations and no BOM.

| * | Add an UTF-8 conversion optimised for ASCII using SSE2Thiago Macieira2011-03-221-1/+54
| | | | | | | | | | | | | | | This code is 2x faster than the original UTF-8 code and within 35% of the pure Latin1 code
| * | Add an UTF-8 conversion code that is optimised for ASCIIThiago Macieira2011-03-221-2/+94
| | | | | | | | | | | | This code is ~1.5x faster than the original UTF-8 code
| * | Add a stateless copy of the Qt 4.7 UTF-8 codec.Thiago Macieira2011-03-221-0/+99
| | | | | | | | | | | | For whatever reason, this code is worse than the stateful code...
| * | Add UTF-8 code benchmarksThiago Macieira2011-03-221-0/+223
| | | | | | | | | | | | | | | | | | Also compare to the Latin1 functions. The UTF-8 algorithm in Qt 4.7 right now is 109% slower than the unoptimised Latin-1 algo, 120% than the Qt 4.7 SSE2 code
| * | Improve a little more the core loop and propagate to the other codeThiago Macieira2011-03-221-18/+22
| | | | | | | | | | | | | | | | | | Currently are that the "improved SSE2" version and the SSE4.1 version are yielding the best results, within 1% of each other. These results are around 20% better than the Qt 4.7 code.
| * | Reduce the number of operations in the main loopThiago Macieira2011-03-221-8/+7
| | | | | | | | | | | | | | | | | | The more operations there are, the more time it takes. More importantly, the more variables we touch, the more the compiler may want to use the stack instead of registers.
