[LLVMdev] No of Datastructures

[Nipun Arora]

Right now I am writing passes just to look for arrays & structs I am trying
to identify the array by parsing the memory description(use regex's)
ex./ { [20 x i8], i32 } *- for a struct. is a structure with a character
array of size 20 and an integer.
I'm not sure if llvm provides an easier way to do this?
The type id for most arrays comes out to be a pointer rather than an array,
its pretty much the same case for structs.

I haven't yet been able to extend this to "logical" structures, and objects
still looking into it. Any ideas?

Thanks
Nipun
