Hi,
We have decided to backport this patch to add support for ARM Cortex-M33 to our
embedded-6-branch.
2016-11-09 Thomas Preud'homme <thomas.preudhomme@arm.com>
Backport from mainline
2016-11-04 Thomas Preud'homme <thomas.preudhomme@arm.com>
gcc/
* 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.
Best regards,
Thomas
