Hi,
With ARM Cortex-M23 and Cortex-M33 and the support for RM profile multilib added
recently, it's time to add the corresponding CPU to architecture mappings in
config/arm/t-rmprofile. Note that Cortex-M33 is mapped to ARMv8-M Mainline
because there is no transitive closure of mappings and the multilib for ARMv8-M
Mainline with DSP extensions is ARMv8-M Mainline.
ChangeLog entry is as follows:
*** gcc/ChangeLog ***
2016-11-30 Thomas Preud'homme <thomas.preudho...@arm.com>
* config/arm/t-rmprofile: Add mappings for Cortex-M23 and Cortex-M33.
Testing: Linking fails before this patch when targeting one of these two cores
and using rmprofile multilib but succeeds with the patch.
Is this ok for stage3?
Best regards,
Thomas
