The host can then query as to the reason for the halt. + * NINDY responds with two bytes of information. + * + * The first byte is a boolean flag that indicates whether or not + * the application has exited. + * + * If the flag is true, the second byte contains the exit code. + * + * If the flag is false, the second byte contains a "reason for + * stopping" code. This file defines the possible values of that + * code. + * + * There are three categories of reasons why the halt may have occurred: + * faults, traces, and software interactions. The first two categories + * are processor-dependent; the values of these codes are tightly coupled + * to the hardware and should not be changed without first examining + * src/nindy/common/fault.c. The software interactions involve + * communication between NINDY and the host debugger; their codes are + * arbitrary. + * + ******************************************************************/ + +#define FAULT_PARALLEL 0x00 +#define FAULT_UNKNOWN 0x01 +#define FAULT_OPERATION 0x02 +#define FAULT_ARITH 0x03 +#define FAULT_FP 0x04 +#define FAULT_CONSTR 0x05 +#define FAULT_VM 0x06 +#define FAULT_PROTECT 0x07 +#define FAULT_MACHINE 0x08 +#define FAULT_STRUCT 0x09 +#define FAULT_TYPE 0x0a + /* 0x0b reserved */ +#define FAULT_PROCESS 0x0c +#define FAULT_DESC 0x0d +#define FAULT_EVENT 0x0e + /* 0x0f reserved */ + +#define LAST_FAULT 0x0f + +#define TRACE_STEP 0x10 +#define TRACE_BRANCH 0x11 +#define TRACE_CALL 0x12 +#define TRACE_RET 0x13 +#define TRACE_PRERET 0x14 +#define TRACE_SVC 0x15 +#define TRACE_BKPT 0x16 + +#define STOP_SRQ 0xfe + /* Application program has service request to make of host */ + +#define STOP_GDB_BPT 0xff + /* Application program has reached breakpoint (fmark) set by host */ |
