Libabigail 2.6 is out!

[Dodji Seketeli]

Hello,

Libabigail 2.6 has been released.

You can download it at
http://mirrors.kernel.org/sourceware/libabigail/libabigail-2.6.tar.xz.

Libabigail is a library which aims at constructing, manipulating,
serializing and de-serializing ABI-relevant artifacts.

It also comes with a set of associated command line tools to compare
the interfaces of ELF binaries resulting from the compilation of C,
C++, Fortran, Ada, Rust, Go or OCaml programs.

Typical use cases of libabigail tools include detecting ABI
incompatible changes across several releases of shared libraries or
incompatible changes in the interface between a Linux kernel and its
modules, for instance.

Users can of course write their own tools using the library.

The library comes with extensive API documentation available online at
https://sourceware.org/libabigail/apidoc.  The tools are documented
online as well at
https://sourceware.org/libabigail/manual/libabigail-tools.html.

Some highlights of this release include:

- Use type hashing during type canonicalization.  This speeds up
a number of pathological test cases.

- Improve Linux Kernel & Modules comparison using CTF and BTF
debug information format.

- Better support of some LLVM-specific DWARF lingo.

Of course, this release also includes the usual load of bug fixes.
