Struct LookupExpression

struct LookupExpression {
    handle: Handle<Expression>,
    type_id: Word,
    block_id: Word,
}

Information about SPIR-V result ids, stored in Frontend::lookup_expression.

Fields

handle: Handle<Expression>

The Expression constructed for this result.

Note that, while a SPIR-V result id can be used in any block dominated by its definition, a Naga Expression is only in scope for the rest of its subtree. Frontend::get_expr_handle takes care of spilling the result to a LocalVariable which can then be used anywhere.

type_id: Word

The SPIR-V type of this result.

block_id: Word

The label id of the block that defines this expression.

This is zero for globals, constants, and function parameters, since they originate outside any function’s block.
