            Bug ID: 19427
           Summary: Intern the strings used in Libabigail
           Product: libabigail
           Version: unspecified
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: default

  Target Milestone: ---

>From the performance work related to bug #19355, it appears that we could
significantly improve the performance of emitting the XML ABI representatio=
n of
a binary by interning the strings
(https://en.wikipedia.org/wiki/String_interning) used to represent the names
and qualified names of types throughout the internal representation of the
Library.

So the idea is to introduce a new abigail::intern_string type, make it
inter-operable with the std::string used elsewhere in the library, provide a
string intern pool that is accessible from the current instance of
abigail::environment, and use that pool to create the interned strings for a
given run of the library that uses a given environment.

Further profiling would tell us if other spots in the library would benefit
from using string interning.
