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.

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.
