Hi,
This patch adds support for the Cortex-M33 processor launched by ARM [1]. The
patch adds support for the name and wires it up to the ARMv8-M Mainline with DSP
extensions architecture and arm_v7m_tune tuning parameters for the time being.
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:
*** gcc/Changelog ***
2016-10-26 Thomas Preud'homme <thomas.preudhomme@arm.com>
* config/arm/arm-arches.def (armv8-m.main+dsp): Set Cortex-M33 as
representative core for this architecture.
* config/arm/arm-cores.def (cortex-m33): Define new processor.
* config/arm/arm-tables.opt: Regenerate.
* config/arm/arm-tune.md: Likewise.
* config/arm/bpabi.h (BE8_LINK_SPEC): Add Cortex-M33 to the list of
valid -mcpu options.
* doc/invoke.texi (ARM Options): Document new Cortex-M33 processor.
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
