Hi,
This patch adds the -mcpu support for the Arm Cortex-M85 CPU which is an
Armv8.1-M Mainline CPU supporting MVE and PACBTI by default.
-mpcu=cortex-m85 switch by default matches to
-march=armv8.1-m.main+pacbti+mve.fp+fp.dp.
Also following options are provided to disable default features.
+nomve.fp (disables MVE Floating point)
+nomve (disables MVE Integer and MVE Floating point)
+nodsp (disables dsp, MVE Integer and MVE Floating point)
+nopacbti (disables pacbti)
+nofp (disables floating point and MVE floating point)
Regression tested on arm-none-eabi and bootstrapped on arm-none-linux-gnueabihf.
Ok for master?
Regards,
Srinath.
