* 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%).
* Add 16-byte loads of the Neon fromLatin1 functionsThiago Macieira2011-03-271-0/+68

* Remove the use of the QtTest baseline feature I revertedThiago Macieira2011-03-221-4/+4

* Use the ARM version of UTF-8 detection in the Neon codeThiago Macieira2011-03-221-16/+13
|
* Update the data files for the QString benchmark testThiago Macieira2011-03-223-204/+71503
| | | | Also add the Neon build flags
* Fix a bug in the SSE2 UTF-8 decoder.Thiago Macieira2011-03-221-0/+4
| | | | | If the multibyte sequence crossed the end of the SSE2 area, then len would have a wrong value and the data wouldn't be read.
* 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.
* Make this compile on Atom/Core2 (no SSE4) and on ARM (no SSE)Thiago Macieira2011-03-221-1/+18

* Add baselines and zeros to the benchmarks.Thiago Macieira2011-03-221-6/+13
|
* Add an UTF-8 conversion on trusted data and no BOM.Thiago Macieira2011-03-221-0/+48
| | | | | This assumes that there are no overlong sequences, no continuation characters without the leading, no missing continuations and no BOM.
* Make it easier to write a UTF-8 conversion on trusted dataThiago Macieira2011-03-221-38/+58
|
* Add the missing tests and 4-byte UTF-8 sequencesThiago Macieira2011-03-221-1/+23
|
* Improve the code and avoid unnecessary storesThiago Macieira2011-03-221-7/+9
| | | | | If there's an UTF-8 high byte in the first 8 bytes, don't try to save the latter 8 characters
* 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.
