The immediate operand is followed by a second OP_AGGREGATE. Next come N component specifications. A component specification is either an OP_OTHERS (others=>...), an OP_CHOICES (for named associations), or other expression (for positional aggregates only). Aggregates currently occur only as the right sides of assignments. */ OP (OP_AGGREGATE) /* An others clause. Followed by a single expression. */ OP (OP_OTHERS) /* An aggregate component association. A single immediate operand, N, gives the number of choices that follow. This is followed by a second OP_CHOICES operator. Next come N operands, each of which is an expression, an OP_DISCRETE_RANGE, or an OP_NAME---the latter for a simple name that must be a record component name and does not correspond to a single existing symbol. After the N choice indicators comes an expression giving the value. In an aggregate such as (X => E1, ...), where X is a simple name, X could syntactically be either a component_selector_name or an expression used as a discrete_choice, depending on the aggregate's type context. Since this is not known at parsing time, we don't attempt to disambiguate X if it has multiple definitions, but instead supply an OP_NAME. If X has a single definition, we represent it with an OP_VAR_VALUE, even though it may turn out to be within a record aggregate. Aggregate evaluation can use either OP_NAMEs or OP_VAR_VALUEs to get a record field name, and can evaluate OP_VAR_VALUE normally to get its value as an expression. Unfortunately, we lose out in cases where X has multiple meanings and is part of an array aggregate. I hope these are not common enough to annoy users, who can work around the problem in any case by putting parentheses around X. */ OP (OP_CHOICES) /* A positional aggregate component association. The operator is followed by a single integer indicating the position in the aggregate (0-based), followed by a second OP_POSITIONAL. Next follows a single expression giving the component value. */ OP (OP_POSITIONAL) /* A range of values. Followed by two expressions giving the upper and lower bounds of the range. */ OP (OP_DISCRETE_RANGE)
