The _exit function currently passes -1 as a "sig" to the _kill function as an invalid signal number so that _kill can distinguish between an abort and a standard exit. For boards using the SYS_EXIT_EXTENDED semi-hosting operation to return a status code, this means that the "status" paramter to _exit is ignored and the return code is always -1. https://developer.arm.com/docs/100863/latest/semihosting-operations/sys_exit_extended-0x20 This patch puts shared code between _kill and _exit into a new function _kill_shared that takes the semi-hosting "reason" to use (if semi-hosting is available) as an argument. For semi-hosting _kill_shared provides that "reason". Without the "sig" argument being used to distinguish between a normal and abnormal exit, the _exit function can provide the return code to be used if the SYS_EXIT_EXTENDED operation is available. Hence the exit code can be returned. |
