Hi, So here is a new proposal: !0 = metadata !{ alloc_siz_fn, offset_fn, parameters* } alloc_size_fn and offset_fn are functions that return either i32/i64 depending on the platform, and they must have the same number of arguments (not necessarily the same as the as allocation function). The parameters are given in the metadata as well. To accommodate...

You'll probably want to write up some docs for the website on how this is supposed to be laid out and work. -eric

Variable length. I think that's the simplest solution, and the additional overhead of a separate array is probably not worth it. > You'll probably wan...
