Performance

• Benchmarks are slower than equivalent C or C++ code

  Clay's library includes bounds check and integer overflow assertions by default, which adds about 10% overhead in typical code. Make sure you test with -Dclay.DisableAssertions to disable all assertions, or -Dclay.DisableAssertions.boundsChecks -Dclay.DisableAssertions.overflowChecks to disable only bounds and overflow check assertions, to get a fair comparison.

Building Clay

• How do I build a debug version of Clay?

  When running cmake, set the CMAKE_BUILD_TYPE attribute: cmake -DCMAKE_BUILD_TYPE=Debug ..

• Clay complains about parser errors on /* tokens

  Older versions of GCC have a compiler bug that breaks Clay's parser. Try updating your GCC, or using Clang.
