- Subject: [PATCH 1/3] Implement new Linux target vectors on BFD
Hi all,
As a followup of my previous patch series, which can be found here:
<http://sourceware.org/ml/gdb-patches/2012-12/msg00534.html>
<http://sourceware.org/ml/gdb-patches/2012-12/msg00536.html>
...and (for this particular patch) as also a followup for Pedro's
comments on:
<http://sourceware.org/ml/gdb-patches/2013-01/msg00233.html>
I am sending this patch for appreciation and review. It is the first
patch of the new PRPSINFO series, and all it does is basically:
1) Add new target vectors on the BFD configury system in order to handle
Linux targets, which will then make it possible to use certain functions
only on such targets, and
2) Hack the existing arch files on BFD (and one specifically on GDB) in
order to correctly declare and use these new targets.
I have chosen not to implement this to all architectures because for now
I only needed the ones which actually implemented the *_write_core_note
function, so you'll see that it touches basically ARM, i*86, x86_64, PPC
and PPC64. As I mentioned above, I had to do modify a GDB file
(ppc-linux-tdep.c) because it declared its BFD target by hand. Not a
big deal.
My first attempt to implement this (suggested by Pedro) was to actually
create a Linux-specific file (e.g., elf64-linux-x86-64.c) which would
#include the original implementation (elf64-x86-64.c in this example)
and extend it by reimplementing some functions. In the end this
approach didn't work because of the way things are laid out in the
original file, so I started looking at the normal procedure for this.
I spent quite some time understanding how the BFD build system worked,
and how to actually hack it, so I hope I did not make any miserable
mistakes here.
Comments are welcome.
