8805 :: llvm wrap

• rforcen (orginal) [2022-01-14T12:11:05+01:00] view original

  in the context of a float expression evaluator,

  i've been toying with llvm to measure performance ratio against a pure nim pcode solution (expression.nim),

  in some cases such ratio exceeds 50,

  attached files cover

  • basic algebraic expression evaluation with
  • parameter passing mechanism and
  • expandable function definition ( in cpp or/and nim),

  lexing functionality is supported by nimly

  llvm.nim / .h: a basic llvm-10 wrapper expression.nim : pcode expression evaluator expression_llvm.nim same w/llvm funcs.nim: additional funcs -> funcs.so funcs.cpp: same as above in .cpp

  Nice!

  You might be interested in https://github.com/arnetheduck/nlvm/pull/18 which provides a full JIT for Nim code using LLVM

  thankx!,

  i sawed the nim-llvm, that's the 'whole thing',

  my idea was to build something that being practical is small and easy to understand as a starting point for something bigger
