[LLVMdev] Machine Code, JIT, and Windows

[Samuel Crow]

Hello Michael,

That's for the final linkage.  Since the JIT does linking at the bitcode level, it doesn't need to access an external linker AFAIK.

Why?
LLVM does not require an external application to

The JIT is in fact compiling to native
