Change Details

This patch shaves off up to two instructions in save_registers_head in exception.S for arm64, which would make more space for instructions that could be added in CheriBSD.

This patch shaves off up to ~~two~~ three instructions in save_registers_head in exception.S for arm64, which would make more space for instructions that could be added in CheriBSD. This is done by # Combining pointer arithmetic with pre-incrementing STP instructions, # Removing the instruction that sets the frame pointer (x29) as its content is unused after 05985a7f805f7ac4844c1a246a3822250d411655.
