23 | /* This file was derived from various remote-* modules. It is a collection | |
24 | of generic support functions so GDB can talk directly to a ROM based | |
25 | monitor. This saves use from having to hack an exception based handler | |
26 | into existance, and makes for quick porting. | |
27 | ||
28 | This module talks to a debug monitor called 'MONITOR', which | |
29 | We communicate with MONITOR via either a direct serial line, or a TCP | |
30 | (or possibly TELNET) stream to a terminal multiplexor, | |
431b7d5f | 31 | which in turn talks to the target board. */ |

33 | /* FIXME 32x64: This code assumes that registers and addresses are at |
34 | most 32 bits long. If they can be larger, you will need to declare | |
35 | values as LONGEST and use %llx or some such to print values when | |
36 | building commands to send to the monitor. Since we don't know of | |
37 | any actual 64-bit targets with ROM monitors that use this code, | |
38 | it's not an issue right now. -sts 4/18/96 */ | |
