comma::RangeChecker::RangeChecker | ( | TypeCheck & | TC | ) | [inline] |
Definition at line 36 of file RangeChecker.h.
Checks a range as used in an integer type declaration.
The following method takes expressions denoting the lower and upper bounds of the range. Semantic analysis performs the following checks:
Note that these types of ranges do not require that the upper and lower bounds be of the same type.
Returns true if the checks succeeded and false otherwise.

DiscreteType * RangeChecker::checkDSTRange | ( | Expr * | lower, | |
Expr * | upper | |||
) |
Checks a range as used as a loop control.
The following method takes the expressions denoting the lower and upper bounds of a discrete subtype declaration (to be used as the control for a loop
statement or as an index specification for an array type). Semantic analysis performs the following checks:
Returns a discrete subtype constrained to the given bounds if the checks succeed and null otherwise.

DiscreteType * RangeChecker::checkSubtypeRange | ( | DiscreteType * | base, | |
Expr * | lower, | |||
Expr * | upper | |||
) |
Checks a range for compatibility wrt a discrete type.
Given a discrete subtype base, checks that the given bounds form a valid constraint over base.
Returns a discrete subtype constrined to the given bounds if the check succeeds and null otherwise.

Resolves the type of range
to the given type.
