Source codes of example and tests in test/ directory.

How to use

Set one of USE_XYZ variable to 'y'.

For example, set USE_NEWLIB=y if you build runtime with CONFIG_USE_NEWLIB. Set USE_GLIBC=y if you use CONFIG_USE_GLIBC.

USE_GLIBC=y make

Use with additional libraries

Some tests depend on external libraries. You need to set WITH_XYZ options to 'y' because these are disabled by default and also need to build and install libraries into sysroot directory before build and run such tests.

Eigen

• Libary: https://gitlab.com/libeigen/eigen

• Test: hello_eigen

• Make option: WITH_EIGEN=y

Build and install:

mkdir build
cd build

cmake ../ -G Ninja -DCMAKE_INSTALL_PREFIX=path/to/sysroot
ninja install

OpenBLAS

• Library: https://github.com/xianyi/OpenBLAS

• Test: sgemm

• Make option: WITH_OPENBLAS=y

This test usually use own naive sgemm function to verify the result, but it can switch to OpenBLAS library to perform sgemm if defined USE_CBLAS macro.

Build and install:
