The Statistical Profile extension included in the ARMv8.2 architecture
adds a number of system registers and a new instruction. This patch set
adds support for the extension to binutils, enabled when
-march=armv8.2-a+profile is given.
The patches in this series:
- Add the new command line option and feature flags.
- Add the new system registers.
- Adjust the maximum number of aliases permitted for an instruction.
- Add support for HINT aliases which take operands.
- Add the new instruction, an alias of the HINT instruction.
This patch adds the option "profile" to the permitted architecture
extensions, disabling it by default.
