FunctionWrappers.jl: Type stable and efficient wrapper of arbitrary functions
Proof of principle implementation of JuliaLang/julia#13984.
Does not handle more than 128 arguments without jlcall wrapper
128 is an arbitrary limit. Should be high enough for all practical cases
Does not support vararg argument types
Wrapper Object cannot be serialized by
dump.cand therefore the precompilation of
FunctionWrappersis done using a runtime branch and by making the wrapper type mutable.
This does not require LLVM trampoline support, which is not currently supported by LLVM
on all the architectures julia runs on (JuliaLang/julia#27174).
Other than this issue
@cfunction should cover all of the use cases.
