| | | | | | This results in no change on the Core-i7, but another 2.6% on the Atom (so it's now 8% better than 4-byte loads and 31% better than current code)

| | | | | | | | | | | The results on i7 are 32% improvement over current code, 13% improvement over 4-byte loads, 6% over the unaligned SSSE3 loads. However, it's about 2.5% slower than pure SSE2 code due to complexity. The results on Atom are 30% improvement over current code, 7% over 4-byte loads, 15% over pure unaligned SSE2 and 9% over unaligned SSSE3.

| | | | | | | | This is a different technique of aligning. Instead of reading some bytes before the string, we will read some bytes of the string twice. Best results are only 2% improvement over the unaligned SSE2 on a Core-i7.
* Add an SSE2-optimised version of ucstrncmpThiago Macieira2010-08-241-1/+38

* Add an SSSE3 version that uses palignr to align.Thiago Macieira2010-08-242-1/+112
| | | | | | | | | Instead of using a non-SIMD method for aligning, we instead load more bytes from p1 and use the PALIGNR instruction to realign to what we want. The result is that it's bit slower than the non-SIMD comparison, due to the complexity. For strings over 8 QChars wide, it's only slightly worse than the non-SIMD comparison.
* Add an SSE2 comparison with prologThiago Macieira2010-08-241-0/+38
| | | | | | | The prolog tries to align p1 to a multiple of 16, so as to run aligned loads, which are faster. Unfortunately, my tests so far indicate that the prolog ends up taking longer than the benefit of having aligned loads.

* | Implement the general blending of ARGB32_pm with SSSE3Benjamin Poulain2010-08-161-0/+43
|/ | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Converting from RGB encoded on 24bits to RGB encoded on 32 bits is quite inefficient. This type of conversion is common for some image format. The patch implement the conversion with SSSE3. This reduce by 3 the number of instructions, pushing the bottleneck to memory bandwidth. On Atom N450, the new benchmark is 40% faster for scanlines of 2000 pixels, 30% faster for scanlines of 32 pixels, and 15% slower for small images (3 and 8px). Reviewed-by: Olivier Goffart

QScriptStaticScopeObject registers all its properties in a symbol table that the JS compiler has access to. If the compiler finds the property in the symbol table, it will generate the fast index-based op_{get,put}_scoped_var bytecodes, rather than the dynamic (slow) op_resolve and friends. If the compiler _doesn't_ find the property in the symbol table, it infers that it's safe to skip the scope object when later resolving the property, which will also improve performance (see op_resolve_skip bytecode). QScriptStaticScopeObject is only safe to use when all relevant properties are known at JS compile time; that is, when a function that has the static scope object in its scope chain is compiled. It's up to the user of the class (e.g. QtDeclarative) to ensure that this constraint is not violated. The API for constructing QScriptStaticScopeObject instances is not public; it lives in QScriptDeclarativeClass for now, an internal class exported for the purpose of QML. The instance is returned as a QScriptValue and can be manipulated like any other JS object (e.g. by QScriptValue::setProperty()). The other part of this commit utilizes QScriptStaticScopeObject in QtDeclarative in the two major places where it's currently possible: 1) QML disallows adding properties to the Global Object. Furthermore, it's not possible for QML IDs and properties to "shadow" global variables. Hence, a QScriptStaticScopeObject can be used to hold all the standard ECMA properties, and this scope object can come _before_ the QML component in the scope chain. This enables binding expressions and scripts to have optimized (direct) access to e.g. Math.sin. 2) Imported scripts can have their properties (resulting from variable declarations ("var" statements) and function declarations) added to a static scope object. This enables functions in the script to have optimized (direct) access to the script's own properties, as well as to global properties such as Math. With this change, it's no longer possible to delete properties of the Global Object, nor delete properties of an imported script. It's a compromise we make in order to make the optimization safe.
