[llvm-dev] JITting COFF objects under Windows/x86
Hello all, MCJIT seems to produce ELF objects under Windows/x86, by using a triple like "x86_64-pc-windows-elf". While it's working fine for most usage, it makes adding precompiled static libraries to the runtime loader a complex task, if said precompiled static library has been compiled traditionally with for instance MSVC (and would thus result in a COFF object). It looks like this choice of using ELF under Windows has been made at the time because the only runtime dynamic loader that LLVM had was for ELF object. That being said, it seems to have a runtime loader for COFF now [1]. So my questions are simple: is this runtime mature enough to be used, and if so, how can we do such a thing? (Indeed, I haven't figured out yet where the "-elf" part of the target triple comes from!). For reference, I would like to use a COFF object to maybe solve this issue: https://github.com/numba/llvmlite/issues/495 . Thanks for any help!
