Flang ABI

Hi there,

I was wondering which ABI flang is going to support, in the context of calling libraries produced by flang from other languages like C or Julia.
I found https://github.com/flang-compiler/flang/issues/89 , but that is about old-flang and not f18.

Is flang going to follow https://gcc.gnu.org/onlinedocs/gfortran/Argument-passing-conventions.html?

Best,
Valentin
