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

[Brian Gaeke]

Changes in directory llvm/lib/ExecutionEngine/JIT:

Emitter.cpp updated: 1.27 -> 1.28

---
Log message:

Make mmap's fd for anonymous memory acquisition default to -1, except on
Linux. This is consistent with what FreeBSD and Solaris both want.
This makes the JIT work on FreeBSD 5.1-RELEASE. Whee.

Diffs of the changes:  (+7 -2)
