The kind mapping is an encoded string that informs FIR how the Fortran KIND values from the front-end should be converted to LLVM IR types. This encoding allows the mapping from front-end KIND values to backend LLVM IR types to be customized by the front-end.
The provided string uses the following syntax.
intrinsic-key : kind-value (, intrinsic-key : kind-value)*
intrinsic-key is a single character for the intrinsic type. 'i' : INTEGER (size in bits) 'l' : LOGICAL (size in bits) 'a' : CHARACTER (size in bits) 'r' : REAL (encoding value) 'c' : COMPLEX (encoding value)
kind-value is either an unsigned integer (for 'i', 'l', and 'a') or one of 'Half', 'BFloat', 'Float', 'Double', 'X86_FP80', or 'FP128' (for 'r' and 'c').
If LLVM adds support for new floating-point types, the final list should be extended.

explicit |
KindMapping constructor with both the kind map and default kinds read from command-line options.
|
explicit |
KindMapping constructor taking a defs argument to specify the default kinds for intrinsic types. To set the default kinds, an ArrayRef of 6 KindTy must be passed. The kinds must be the given in the following order: CHARACTER, COMPLEX, DOUBLE PRECISION, INTEGER, LOGICAL, and REAL. The kind map is read from command-line options, if given.

explicit |
KindMapping constructor taking an optional defs argument to specify the default kinds for intrinsic types. To set the default kinds, an ArrayRef of 6 KindTy must be passed. The kinds must be the given in the following order: CHARACTER, COMPLEX, DOUBLE PRECISION, INTEGER, LOGICAL, and REAL.

Translate a default kinds string into a default kind vector. This vector can be passed to the KindMapping ctor.
