[llvm-dev] Static constructors with ORC JIT?

[Daniele Vettorel via llvm-dev]

Thank you Alex,

I went and implemented a solution along those lines. It works well.

It may be worth mentioning static constructors in the Kaleidoscope tutorial.

Cheers,
Daniele

Hi Daniele,

The easiest way is to collect the constructors from the modules and then execute them manually as you would with any other function.
The simplest solution is to take this code and modify it to get the list of constructor functions:
https://github.com/llvm-mirror/llvm/blob/1154d31e8c429e53307d3fc0edd13d9b261c26dc/lib/ExecutionEngine/ExecutionEngine.cpp#L370

This might be not the most ideal solution, but it works.

Cheers,
Alex.
