Hi, We have decided to backport this patch to add multilib support for ARM Cortex-M23 and Cortex-M33 to our embedded-6-branch. *** gcc/ChangeLog *** 2016-11-30 Thomas Preud'homme <thomas.preudhomme@arm.com> * config/arm/t-rmprofile: Add mappings for Cortex-M23 and Cortex-M33. Best regards, Thomas 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.preudhomme@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
