Suppose a function private_foo() has a symbol private_foo and also a
another one (an alias) named public_foo. Then suppose we want to
filter out sub-type changes to private_foo(). But then we still want
to see changes to public_foo.
This patch does add this feature. The [suppress_function] directive
now has a new (hidden) boolean 'allow_other_aliases' property. When
set to 'yes' or 'true', if the function being looked at has an alias
symbol that does *NOT* match the other properties of the directive,
then the directive doesn't suppress reports for the function. This
new property is set to yes by default.
This means that when a function has got multiple aliases, to suppress
the function, one needs to write a regular expression that matches the
names of aliases. Otherwise the function will not be suppressed.

set}_allow_other_aliases): Declare new member functions.
* src/abg-comparison.cc
(function_suppression::priv::allow_other_aliases_): New data
member.

(function_suppression::{get, set}_allow_other_aliases): Define new
member functions.
(read_function_suppression): Parse the new "allow_other_aliases"
property.
(function_suppression::suppresses_function): Update to evaluate
the new 'allow_other_aliases' property when there is a property to
match against some a symbol name of the function.
(corpus_diff::report): Fix the printing of function aliases when
printing sub-type changes to properly emit the plural of the word
'symbol' when the function has several aliases.

new member function.

This is the Application Binary Interface Generic Analysis and Instrumentation Library. It aims at constructing, manipulating, serializing and de-serializing ABI-relevant artifacts. The set of artifacts that we are intersted is made of quantities like types, variable, fonctions and declarations of a given library or program. For a given library or program this set of quantities is called an ABI corpus. This library aims at (among other things) providing a way to comparing two ABI Corpuses, provide detailed information about their differences, and help build tools to infer interesting conclusions about these differences. You are welcome to contribute to this project after reading the files CONTRIBUTING and COMMIT-LOG-GUIDELINES files in the source tree. Communicating with the maintainers of this project -- including sending patches to be include to the source code -- happens via email at libabigail@sourceware.org.
