Perhaps I scanned too quickly. I probably missed since there is no actual mention of ABI (or e.g. which calling conventions it supports on what platforms). The page is confusing - it seems to discuss ABI and syntax and stuff, which isn't exactly related to "compatability" afaict.
I digress... just the usual problems with wiki-type sites.
It compiles to LLVM and LLVM abstracts the calling convention. So it might be safe to assume it supports all the calling conventions that LLVM supports.
