Hello all, In most (all?) the SMP ports, we have in the CPU Context Control: bool is_executing;
This variable often is accessed through assembly language (i.e., during the context switch), using something like ARCH_CONTEXT_CONTROL_IS_EXECUTING_OFFSET. Unfortunately, the 'bool' type is not standard, or rather its size is implementation-defined. I think it is generally an 8-bit value though for us. I see that the riscv port uses explicitly a uint32_t so that's nice. I think we should replace 'bool' with uint8_t in the other ports that are using byte-size accesses from assembly, just to be well-defined. Most likely, this doesn't actually affect anything and I'm just a little paranoid.
