[PATCH, gas/ARM] Add support for Cortex-M23

[resending with mailing list also as recipient this time]


This patch adds support for the Cortex-M23 processors launched by ARM [1]. The patch adds support for the name and wires it up to the ARMv8-M Baseline architecture. It also updates documentation to mention this new processor.


ChangeLog entry is as follows:

*** gas/Changelog ***

2016-10-26  Thomas Preud'homme  <>

         * config/tc-arm.c (cortex-m23): Declare new processor.
         * doc/c-arm.texi (cortex-m23): Document new processor.

Tested by building libgcc and libstdc++ for Cortex-M23 and running a hello world compiled for it.

Is this ok for master?

Best regards,
