[LLVMdev] LLVMInitializeNativeTarget error

[Keith Sheppard]

Hi, I've made some progress...

Apparently the LLVMInitializeNativeTarget symbol never makes it's way
into the shared library which makes sense since it's declared static
in the header. So it works if I directly call the
LLVMInitializeX86Target function as in the following updated version:

<https://github.com/keithshep/llvm-fs/blob/c52273a68bf89f205e8e29ce852a5cb050c262c6/test/simpletest2.fs>

It seems like a hack to do it this way though. Is there any technical
reason LLVMInitializeNativeTarget can't be built into the shared
library? Would the LLVM group be open to accepting a patch for making
this function available in the library?

Thanks, Keith
