Dodji Seketeli 2d276b67ed ir: Tighten type comparison optimization for Linux kernel binaries
types_defined_same_linux_kernel_corpus_public() performs an
optimization while comparing two types in the context of the Linux
kernel.  If two types of the same kind and name are defined in the
same corpus and in the same file, then they ought to be equal.

For two anonymous classes that have naming typedefs, the function
forgets to ensure that the naming typedefs have the same name.

I have no binary that exhibits the potential issue, but I stumbled
upon the problem while looking at something else that uncovered
the problem.  This change doesn't impact any of the binaries of the
regression suite at the moment, though.

Fixed thus.

	* src/abg-ir.cc (types_defined_same_linux_kernel_corpus_public):
	Ensure that anonymous classes with naming typedefs have identical
	typedef names.

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 compare
two ABI Corpora (apparently the plural of corpus is copora, heh,
that's cool), 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
