* | WebGradients: redo implementationGiuseppe D'Angelo2019-12-141-5/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous implementation was *extremely* expensive. It relied on loading a binary JSON file from resources (which involved decompressing it), then extracting information out of it to build a gradient. Already-loaded gradients were kept in a local cache, which had to be mutex protected. Instead, this patch extends the gradient generator to build static arrays filled with the web gradient data, sitting in .rodata. These arrays are used when building QGradient objects with a web gradient. No explicit mutex protection is necessary, since accesses will just read from the arrays. As benefits, this patch removes: * the binary json representation from QtGui's resources (~4KB compressed, ~50KB uncompressed) * the overhead of reading from the JSON for each used web gradient; * the startup costs of registering the webgradients in the resources; * all the overhead of mutex locking when building such gradients; * all the runtime memory allocations to load, parse and cache the web gradients (including the memory + CPU spike on first load due to the uncompression of the JSON data, as well as a couple of deep copies).

* Say hello to Android multi arch build in one goBogDan Vatra2019-08-261-12/+30
| | | | | | | | | | | | | | Multi arch build in one go is need to support the new .aab packaging format. By default the users apps are built for all Android ABIs: arm64-v8a armeabi-v7a x86_64 x86 The user can pass ANDROID_ABIS to qmake to filter the ABIs during development, e.g. qmake ANDROID_ABIS="arm64-v8a armeabi-v7a" will build only for arm ABIs.

* SIMD: Add a haswell sub-architecture selection to our supportThiago Macieira2018-07-091-1/+1
| | | | | | | | | | | | | | | | | As the comment says, Haswell is a nice divider and is a good optimization target. I'm using -march=core-avx2 instead of -march=haswell because the latter form was only added to GCC 4.9 but we still support 4.7 and that has support for AVX2. This commit changes the AVX2-optimized code in QtGui to Haswell- optimized instead. That means, for example, that qdrawhelper_avx2.cpp can now use the FMA instructions.

| | | | | | | | | | | | | | | | There's no external arm assembler to fall back on here. The actual assembly is already disabled since 8072c36eebd064, but passing the empty assembly file to any random external assembler could end up producing an empty object file for the host environment instead of the target, in a cross build.

All it does is verify whether the arch detection found "neon" as part of the target CPU features. In other words, it moves the test that was in simd.prf to configure. It does fix the Neon detection in configure.exe, which was always failing for trying to run a test that didn't exist (config.tests/unix/neon).

* Remove runtime detection of SSE2Thiago Macieira2014-01-161-2/+4
| | | | | | | | | | | | | | | | | | If the compiler supports SSE2, we'll use our SSE2-optimised code unconditionally. Runtime detection is left for SSSE3 code. The SSE2 codebase is big and thus a timebomb if an inline function gets leaked out and run without runtime check. In reality, it's extremely unlikely people running CPUs without SSE2 support are running Qt 5 at this moment (they're either too old or too new, e.g. Intel Quark). The SSSE3 codebase is a lot more manageable.

* Remove the files building AVX codeThiago Macieira2013-12-101-1/+0
| | | | | | | | | | | | | | | This feature was never completely implemented. Sure, it's nice to build the SSE2 + SSSE3 code with the VEX prefix, which results in better code. But the leap isn't that big anyway. This is the first step to removing the runtime detection for the drawhelpers. They create timebombs when we use inline functions.

* iOS: Enable NEON optimizations, except for the pixman draw-helpersTor Arne Vestbø2013-04-041-3/+6
| | | | | | | | | | We used to disable NEON completely, as the iOS toolchain does not handle the GAS syntax of the pixman draw-helpers. But we can limit the disabling to just the draw-helpers, which means we get NEON optimization of eg. QImage and QString.
