Let me know If you would rather I did this to fit in with the x86 sim port. In the meantime (or otherwise) I will probably implement Francois' excellent suggestion, it seems much nicer than using a `uint64_t` to me. `typedef uint32_t __attribute__((aligned(8))) os_stack_t;` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
