[llvm-commits] CVS: llvm/lib/ExecutionEngine/JIT/Emitter.cpp

[Chris Lattner]

Changes in directory llvm/lib/ExecutionEngine/JIT:

Emitter.cpp updated: 1.40 -> 1.41

---
Log message:

This code is a real mess, but at least get the JIT *building* on platforms
(such as plan 9) without mmap.  Of course it won't RUN... but that's another
step.  :)
