Re: readelf patch
Hi Stephen, Here is a patch to add support to readelf for showing the details of two more types of NetBSD ELF notes. The patches are taken from the cvs repo of NetBSD, where the changes were applied to their copy a while back. Do you have a binutils FSF copyright assignment on file ? (I looked but did not find one). Without it then we normally cannot accept patches like this. In this particular case however I have accepted the patch, because I feel that it counts as "obvious". So the patch is now in, along with these changelog entries: Cheers Nick binutils/ChangeLog 2015-10-27 Stephen Fisher * binutils.c (process_netbsd_elf_note): New function. (process_note): Call the new function for NetBSD core notes. include/elf/ChangeLog 2015-10-27 Stephen Fisher * common.h (NT_NETBSD_MARCH): Define. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils

I didn't write the original code, someone in the NetBSD project did and put it in their cvs repository. If that's a problem, I'd be happy to re-write it (I wrote my own until I realized NetBSD had implemented the feature already) and sign a copyright assignment. > In this particular case however I have accepted the patch, because I > feel that it counts as "obvious".

I have checked the patch in, but in the future please could you include a ChangeLog entry to go along with the patch, and if possible a testcase to check the patch. I was somewhat surprised to discover that we do not have any RL78 specific gas tests, so I have taken the liberty of creating a new directory in the testsuite and adding a test for this PR. I hope that over time people will add more RL78 tests to this directory.
