[Dotgnu-libjit] RE: Declaring temporary array

Hi.  I just sent an email (see below) regarding arrays.  I just noticed that you have an alloca instruction, which is what I was looking for.  Presumably jit_insn_alloca() returns a jit void pointer type.  If I have this right, and this is how you would implement arrays on the stack, then there's no need to respond to my question.  Thanks.

Hi.  I'm really new to libjit, so this question is likely to be one you've seen before (although I could not find it in your archives).  I'd like to create a temporary array from the stack (not heap) using libjit.  I noticed that the only types of values that can be created are standard types (ints, bytes, etc) and structs/unions.  Would I need to create an array using structs, where all the fields required in the array are the same type?  That doesn't seem right, so I suspect I have it wrong.  I would appreciate your help on declaring this array off the stack - my alternative would be to pass in a "temp array' into the function I'm building so references can be made into it.
Also, a few other questions:
1. It seems like the max optimization level supported in libjit is 0.  Perhaps I don't have the latest version?
2. Any work going on in supportin ia64 code generation?
