[resending with mailing list also as recipient this time] Hi, This patch adds support for the Cortex-M33 processors launched by ARM [1]. The patch adds support for the name and wires it up to the ARMv8-M Mainline with DSP extensions architecture. It also updates documentation to mention this new processor. [1] http://www.arm.com/products/processors/cortex-m/cortex-m33-processor.php ChangeLog entry is as follows: *** gas/Changelog *** 2016-10-26 Thomas Preud'homme <thomas.preudhomme@arm.com> * config/tc-arm.c (cortex-m33): Declare new processor. * doc/c-arm.texi (cortex-m33): Document new processor. *** include/ChangeLog *** 2016-10-26 Thomas Preud'homme <thomas.preudhomme@arm.com> * opcode/arm.h (ARM_AEXT_V8M_MAIN_DSP): Define. (ARM_AEXT2_V8M_MAIN_DSP): Likewise. (ARM_ARCH_V8M_MAIN_DSP): Likewise. Tested by building libgcc and libstdc++ for Cortex-M33 and running a hello world compiled for it. Is this ok for master? Best regards, Thomas
