I have ported over the [x86_128-inl.h](https://github.com/johnplatts/highway_ppc_port/blob/master/hwy/ops/x86_128-inl.h) header over to Altivec/VSX, and the changes needed to support Altivec/VSX can be found in the https://github.com/johnplatts/highway_ppc_port repository. The [ppc_altivec-inl.h](https://github.com/johnplatts/highway_ppc_port/blob/master/hwy/ops/ppc_altivec-inl.h) contains the implementation of...

I have created a branch at https://github.com/johnplatts/FlatLaf_Win32_Native_Fix/tree/flatlaf_win32_native_fix that includes fixes to flatlaf-natives/flatlaf-natives-windows/src/main/cpp/ to fix the issues surrounding memory allocation failures and overflow in HWNDMap::ensureCapacity.

@jan-wassenberg I have been using qemu 6.2.0, qemu 7.2.0, and Ubuntu 22.04 on x86-64 to develop the port of Google Highway to PPC. Here is how to set up a...

Here is an example of a project that allows Google Highway to be used in a header-only manner if compiling for a single HWY_TARGET: https://github.com/johnplatts/simdhwyhash The [CMakeLists.txt](https://github.com/johnplatts/simdhwyhash/blob/4f2f052d1896caa49331391fb4baa638f547a884/CMakeLists.txt) file in [simdhwyhash](https://github.com/johnplatts/simdhwyhash)...

Here is a function that can detect if an optional CPU feature is present on MacOS/iOS/iPad: ``` static HWY_INLINE bool HasCpuFeature(const char* feature_name) { int result = 0; size_t len...

AVX3/AVX3_DL target detection also should be updated for x86_64 on MacOS as (a) XGETBV might fail to report support for ZMM vectors and AVX3 mask registers on MacOS (even in...
