This library provides the compile-time support for OpenMP needed by Faasm functions.

omp.h is copied from Clang 8.0.1. (actual OMP version is detailed the file itself).

The definition of Faasm's OpenMP interface can be found in the libfaasmp directory.

To add a new function you need to include it in both the libfaasmp definition and the Faasm host interface.

LLVM adds GNU compatibility data symbols on some features for synchronisation. The wasm linker needs to be aware of the sizes and the names of the symbols, which are not valid C/C++ identifiers, and as such are resolved in assembly in libfaasmp/z_Linux_asm.S file.

An error from the linker when compiling new parts of the API implies you need to add the symbol to this file.
