◆ handleAccelTables()

bool DWARFVerifier::handleAccelTables ( )

Verify the information in accelerator tables, if they exist.

Any errors are reported to the stream that was this object was constructed with.

Returns
true if the existing Apple-style accelerator tables verify successfully, false otherwise.

Verify the information in any of the following sections, if available: .debug_abbrev, debug_abbrev.dwo.

Any errors are reported to the stream that was this object was constructed with.

Returns
true if .debug_abbrev and .debug_abbrev.dwo verify successfully, false otherwise.
