ali.ads, ali.adb (Scan_ALI): Initialize XE.Tref to a known default value.
2007-10-15 Emmanuel Briot <briot@adacore.com>
* ali.ads, ali.adb (Scan_ALI): Initialize XE.Tref to a known default
value.
(Xref_Record): Change type for Line, since in the case of a reference to
a predefined entity (as happens for array index types), the line is set
to 0.
Add support for parsing multiple array index types info, or
multiple inherited interfaces info. This information cannot be stored
in Xref_Entity_Record, which only supports a single instance of Tref_*,
and is therefore stored in the list of references instead. It has a
special treatement later on in tools that use this information.
