*Note: Please adhere to [Contributing Guidelines](https://github.com/apache/nuttx/blob/master/CONTRIBUTING.md).* ## Summary Make sure the registers context size is aligned to 16bytes as required by armv8-a. This issue has been reported earlier, thus make sense to make sure it won't happen in future. ## Impact No impact on existing code. ## Testing Tested with qemu build and pass. ``` cmake -Bbuild -GNinja -DBOARD_CONFIG=qemu-armv8a:nsh_smp nuttx ``` If `ARM64_CONTEXT_REGS` is configured to wrong value like `37`. It reports error. ``` In file included from /home/neo/projects/nuttx/nuttx/include/nuttx/irq.h:39, from /home/neo/projects/nuttx/nuttx/sched/signal/sig_allocpendingsigaction.c:32: /home/neo/projects/nuttx/build/include/arch/irq.h:165:4: error: #error "ARM64_CONTEXT_REGS must be even to make stack aligned to 16 bytes" 165 | # error "ARM64_CONTEXT_REGS must be even to make stack aligned to 16 bytes" | ^~~~~ ninja: build stopped: subcommand failed -- This is an automated message from the Apache Git Service.
