OK. Don't forget to update the NEWS file.
I wasn't sure I should. I didn't see any entry for new processor support in the
NEWS file. It seems we (ARM but also the community in general I think) only
mention architecture.
I'm happy to change our behavior (and I think it makes sense to announce any
interface change) but I just want an extra confirmation from you:
*** gas/ChangeLog ***
2016-10-27 Thomas Preud'homme <thomas.preudhomme@arm.com>
* config/tc-arm.c (cortex-m23): Declare new processor.
* doc/c-arm.texi (-mcpu ARM command line option): Document new
Cortex-M23 processor.
* NEWS: Mention Cortex-M23 support.
Ok for master?
Best regards,
Thomas
