llvm dev - Mar 2018 - MCJIT with LLVM >= 5.0 on Windows 64

Hello,

I am using the Faust language which leverages LLVM's MCJIT for code
generation (http://faust.grame.fr/).

There are some problems[1] when generating code and executing it afterwards
on Windows with a MSVC "host" (that is, LLVM itself and the software
it is
used in are built with MSVC).
It works fine when building LLVM / Faust with Mingw.
On MSVC the code is generated with x86_64-pc-windows-msvc-elf as target
triple, but there are crashes as soon as this code is executed.

Relevant LLVM usage in Faust is here:
https://github.com/grame-cncm/faust/blob/master-dev/compiler/generator/llvm/llvm_dynamic_dsp_aux.cpp

I also found this topic which could be relevant, but I'm not knowledgeable
enough to tell :

Hi Jean-Michaël,

Is this a regression from previous versions of LLVM? Or had you always been
using Mingw previously?

Cheers,
Lang.
