Subject: [PATCH v2 0/8] Refactor dwarf-reader: split out ELF helpers
Date: Tue, 21 Apr 2020 08:35:43 +0200	[thread overview]
Message-ID: <20200421063551.222511-1-maennich@google.com> (raw)
In-Reply-To: <20200420110846.218792-1-maennich@google.com>

The abg-dwarf-reader.cc has grown into a large compilation unit with a lot of
responsibilities. This does not only affect the compilation time, but also
readability of the various implementation details. Hence it makes sense to
attempt a refactoring of parts of it.

To overcome the above and as a preparation for my future work on the symtab
reading part, this splits out functionality from the dwarf reader into a new
set of source files: src/elf-helpers.{h,cc} along with a test that so far only
serves the purpose of ensuring that the header file can be compiled on its own.

The elf-helpers, sensibly not named elf-utils, contain functionality like
looking up sections, converting values or deducting information and properties
in some way from an Elf* handle. They are not exposed to libabigail users as
they are an implementation detail of libabigail.

This set of changes is only a refactoring with minor cleanups and renames and
any change to the functionality would be unintentional.

Cheers,
Matthias
