Detailed Description

This file defines some C++17 template classes that are used to convert the signatures of plain old C functions into a model that can be used to generate MLIR calls to those functions. This can be used to autogenerate tables at compiler compile-time to call runtime support code.

Macro Definition Documentation

FirE

#define FirE	(		L,
			I
	)		(I < sizeof(L) / sizeof(*L) ? L[I] : 0)

These macros are used to create the RuntimeTableEntry for runtime function.

For example the runtime function SumReal4 will be expanded as shown below (simplified version)

fir::runtime::RuntimeTableEntry<fir::runtime::RuntimeTableKey<
    decltype(_FortranASumReal4)>, "_FortranASumReal4"))>

These entries are then used to generate the MLIR FunctionType that correspond to the runtime function declaration in C++.
