llvm dev - Dec 2013 - [LLVMdev] MCJIT + Windows = Incompatible object format

Is the MCJIT infrastructure supported on Windows? I'm getting an "LLVM
ERROR: Incompatible object format!" when running my project with both VS
2013 and Mingw_w64 (GCC 4.8.2). Looks like this issue has been brought up
before [1,2] and the answer is "almost". Any help would be greatly
appreciated.

v/r,
Josh

Hi Josh,

JIT/MCJIT works on Windows 32 bit (maybe 64 also) with ELF object file
format:

  -target i686-pc-mingw32-elf

As Yaron said, you need to add "-elf" to the end of your target triple
to get MCJIT to generate ELF object in memory on Windows.  This should work with
32- or 64-bit targets.

Bingo, thanks! Confirmed it works for both 32- and 64-bit targets.

Should `sys::getProcessTriple()` be updated with this change? According to
the documentation:

  /// getProcessTriple() - Return an appropriate target triple for
generating
  /// code to be loaded into the current process, e.g. when using the JIT.

I had to "-elf" to the result of this function for JIT to work on
Windows.

v/r,
Josh
