<DIV>Thanks for the response :D<BR></DIV>
<DIV></DIV>
<DIV>I have used Python and Lua before. I'd love to use the syntax of lua with
the object oriented ness of python, and I thought LLVM would be a way to do
that.</DIV>
<DIV></DIV>
<DIV>Again your help is appreciated.</DIV>

Hello there!<BR>> I'm an absolute newb at LLVM,and I was hoping someone
could answer a few of<BR>> my questions.<BR>> I'm currently working on a
game engine. As part of it's design, I need a<BR>> virtual machine for
scripts. Is LLVM suited for this at all? Such as<BR>> registering external
functions that can be called from the scripts?<BR><BR></DIV>Possibly... but
you're sort of making the decision at the wrong level;<BR>LLVM is really a
low-level solution intended for implementing a<BR>language. If you need
scripts, you probably want a scripting language<BR>of some sort, and if you're
working on a game engine, you probably<BR>don't want to write your own
scripting language, since it's a lot of<BR>work with no obvious benefit.
There are numerous existing open-source<BR>solutions for this; I think
Python and Lua are popular choices for<BR>that sort of thing.<BR>
<DIV class=im><BR>> And if<BR>> this did work, it wouldn't really matter
what language the original scripts<BR>> were written in, since they all get
compiled down to the LLVM bytecode<BR>> correct?<BR><BR></DIV>You can't
really just compile a scripting language down to LLVM<BR>bitcode and expect
good performance; you really need some glue code to<BR>mix interpretation,
compilation, and possibly recompilation at runtime<BR>to get good performance.
And if the scripts in question aren't<BR>performance-sensitive, there's
not really much point to using LLVM.<BR>It strongly depends on what you're
doing.<BR>
<DIV class=im><BR>> As of now what platforms does LLVM not compile on? Is
it good for embedded<BR>> work?<BR><BR></DIV>In terms of platforms, it'll
probably work for everything you might<BR>care about; see <A
href="http://llvm.org/docs/ReleaseNotes-2.6.html#portability"
target=_blank>http://llvm.org/docs/ReleaseNotes-2.6.html#portability</A><BR>(although
note that only some of those platforms have working JIT<BR>support). As
for embedded work, it depends on what you mean by<BR>embedded; if 10MB code
footprint sounds way too large, LLVM is<BR>probably not the way to
go.<BR><BR>You might want to take a look at <A
href="http://llvm.org/docs/tutorial/"
target=_blank>http://llvm.org/docs/tutorial/</A> to get<BR>a better idea of
what LLVM can
do.<BR><BR>-Eli<BR>_______________________________________________<BR>LLVM
