[J3] BIND(F)?

[Jeff Hammond]

One important feature of BIND(C..) is that, because C has an ABI, such interfaces are compiler independent.  Will BIND(F..) have that property or not?  I doubt it.  It sounds like more of a BIND(F_BUT_JUST_MY_COMPILER..) interface.

It seems to me that if one is going to add such a feature, it should be a true implementation of BIND(F..) and allow users to build Fortran DSOs that always work, and not just with the same compiler that created them.  Otherwise, they are not particularly useful as DSOs.

It seems a natural request then to allow a procedure to be declared BIND(F, name=”…”)   The procedure could then even live inside of a module (amusingly allowing the module to have no PUBLIC entities).

Is this unworkable for reasons that I don’t understand?   Low priority?    Or maybe a very small feature that could be put into 202y?
Every compiler I have used has syntax (usually a directive) to specify the global name of a procedure - ALIAS is often the keyword. It does sound like a small but useful feature that could be proposed for 202Y. One might quibble with the syntax suggested, but the basic idea is sound.
