Integrate Sleef (https://sleef.org/) as one of the choices of supported math libraries in ISPC. Sleef is an open source SVML-like library that has float32 and float64 implementations of all math...

ISPC currently defaults to 32-bit addressing mode, which offers performance advantages in certain scenarios but may introduce risks of address calculation truncation. The 32-bit addressing mode sometimes provides performance benefits,...

Tutorial on how to use ISPC with modern CMake

1

A simple ISPC example using modern CMake is needed. Here are some references demonstrating ISPC integration with modern CMake: [CMake ISPC Tests](https://gitlab.kitware.com/cmake/cmake/-/tree/master/Tests/ISPC) [ISPC Modern CMake Example](https://github.com/ispc/ispc/blob/main/examples/cpu/cmake/AddISPCExampleModern.cmake) While these provide useful...

The point of this test is to verify that ISPC actually defines the macros we claim to define in the documentation here https://ispc.github.io/ispc.html#the-preprocessor. Empty test with ispc -o - -E...
