Low Level Virtual Machine (http://llvm.org/):

Also, add a place for vendor version info.

Change the verifier to never throw an exception.  Instead verifyModule canoptionally return the string error, which is an easier api for clients touse anyway.

will be profitable.  This is mainly to remove some cases where excessive
unswitching would result in long compile times and/or huge generated code.

Once someone comes up with a better heuristic that avoids these cases, this
