This is a repository for the test suite for DirectXMath on GitHub.

Setup

• Install git
• Install CMake, Ninja, and MSVC or clang/LLVM for Windows

git clone https://github.com/Microsoft/DirectXMath.git
cd DirectXMath
git clone https://github.com/walbourn/directxmathtest.git Tests
git clone https://github.com/Microsoft/DirectXMath.wiki.git wiki

Running tests

CTest is supported

cd DirectXMath
cmake --preset=x64-Debug
cmake build out\build\x64-Debug
ctest --preset=x64-Debug

math3

This is the main DirectXMath test suite which is a console application.

Configurations

All configs use /fp:fast.

All Release configs use /Ox.

• Debug/Release: x86 builds with /arch:SSE2 which is the default for x64
• NI Debug/NI Release: Same as Debug/Release but with _XM_NO_INTRINSICS_ set
• x87 Debug/X87 Release: Same as NI Debug/NI Release with /arch:IA32 set. Note there is for the x86 platform only.
• SSE3 Debug/SSE3 Release: Same as Debug/Release but with SSE3 optimizations.
• SSE4 Debug/SSE4 Release: Same as Debug/Release but with SSE4.1 optimizations.
• AVX Debug/AVX Release: Same as Debug/Release but with /arch:AVX which includes SSE3, SSE4.1, and AVX optimizations.
• AVX2 Debug/AVX2 Release: Same as Debug/Release but with /arch:AVX2 which includes SSE3, SSE4.1, AVX, and F16C optimizations.
