395/**
396 * There are two ways of implementing QueryInterface, and we use both:
397 *
398 * Table-driven QueryInterface uses a static table of IID->offset mappings
399 * and a shared helper function. Using it tends to reduce codesize and improve
400 * runtime performance (due to processor cache hits).
401 *
402 * Macro-driven QueryInterface generates a QueryInterface function directly
403 * using common macros. This is necessary if special QueryInterface features
404 * are being used (such as tearoffs and conditional interfaces).
405 *
406 * These methods can be combined into a table-driven function call followed
407 * by custom code for tearoffs and conditionals.
