- archContextSwitch stores address of new thread's struct reent in ctx_switch_info - pend_sv_handler uses address in ctx_switch_info.reent instead of fixed offset into atom_tcb - added header with defines for offsets into struct ctx_switch_info used in assembler code. Also added compile time verification for this offsets
