All,
The default for the experimental JIT compiler is enabled whenever Octave
has been built with support for it. I know Matlab has their JIT compiler
enabled by default, but theirs is not a new thing and has been extensively
tested.
I think it would be more prudent for Octave to disable JIT by default and
have any interested users specifically enable it and experiment with it.
Eventually we can switch things around if warranted. Any thoughts?
I would add a new command line option '--jit-compiler' to enable JIT from
the start of Octave since it would now be disabled to begin with.

That is OK with me. I used it for quite a while, until a Fedora update
installed
llvm 3.2. Until it would no longer compile it worked without problems.
As long as llvm makes frequent configuration an API changes there will be
problems maintaining a stable build environment. This is separate from
whether
it should be enabled by default, of course.
