bnjbvr closed Issue #1273:

I'm looking at the documentation for https://docs.rs/cranelift-codegen/0.51.0/cranelift_codegen/ir/fn.get_libcall_funcref.html and I'm not sure how to get an Inst to pass to it. It looks like Inst is returned by InstBuilder.call, but that requires me to have a FuncRef with the same signature already. Am I missing something obvious? It would seem to make more sense to have it take a Signature ...

Context: I'm trying to call memcpy from libc to fix https://github.com/jyn514/rcc/issues/71.
