// This file defines the supported intrinsic procedures and implements
// their recognition and validation. It is largely table-driven. See
// docs/intrinsics.md and section 16 of the Fortran 2018 standard
// for full details on each of the intrinsics. Be advised, they have
// complicated details, and the design of these tables has to accommodate
// that complexity.
// Dummy arguments to generic intrinsic procedures are each specified by
// their keyword name (rarely used, but always defined), allowable type
// categories, a kind pattern, a rank pattern, and information about
// optionality and defaults. The kind and rank patterns are represented
// here with code values that are significant to the matching/validation engine.
// An actual argument to an intrinsic procedure may be a procedure itself
// only if the dummy argument is Rank::reduceOperation,
// KindCode::addressable, or the special case of NULL(MOLD=procedurePointer).
// These are small bit-sets of type category enumerators.
// Note that typeless (BOZ literal) values don't have a distinct type category.
// These typeless arguments are represented in the tables as if they were
// INTEGER with a special "typeless" kind code. Arguments of intrinsic types
// that can also be typeless values are encoded with an "elementalOrBOZ"
// rank pattern.
// Assumed-type (TYPE(*)) dummy arguments can be forwarded along to some
// intrinsic functions that accept AnyType + Rank::anyOrAssumedRank or
// AnyType + Kind::addressable.

// to the specific intrinsic result type if needed. This also prevents
// using the generic name so that folding can insert the conversion on the
// result and not the arguments.
//
// This is not enabled on all specific intrinsics because an alternative
// is to convert the actual arguments to the required dummy types and this is
// not numerically equivalent.
// e.g. IABS(INT(i, 4)) not equiv to INT(ABS(i), 4).
// This is allowed for restricted min/max specific functions because
// the expected behavior is clear from their definitions. A warning is though
// always emitted because other compilers' behavior is not ubiquitous here and
// the results in case of conversion overflow might not be equivalent.
// e.g for MIN0: INT(MIN(2147483647_8, 2*2147483647_8), 4) = 2147483647_4
