Thanks to spec tests we can ensure 100% compatibility with the WebAssembly spec test suite.
You can run all the tests with:
make test
make test
will automatically detect the compilers available on your system.
Please follow the Building from Source guide see how you can prepare your system with the requirements needed for each of the backends.
Each compiler integration can be tested separately:
Singlepass: make test-singlepass
Cranelift: make test-cranelift
LLVM: make test-llvm
