/* This module implements "target record", also known as "process
|
|
|
|
record and replay". This target sits on top of a "normal" target
|
|
|
|
(a target that "has execution"), and provides a record and replay
|
|
|
|
functionality, including reverse debugging.
|
|
|
|
|
|
|
|
Target record has two modes: recording, and replaying.
|
|
|
|
|
|
|
|
In record mode, we intercept the to_resume and to_wait methods.
|
|
|
|
Whenever gdb resumes the target, we run the target in single step
|
|
|
|
mode, and we build up an execution log in which, for each executed
|
|
|
|
instruction, we record all changes in memory and register state.
|
|
|
|
This is invisible to the user, to whom it just looks like an
|
|
|
|
ordinary debugging session (except for performance degredation).
|
|
|
|
|
|
|
|
In replay mode, instead of actually letting the inferior run as a
|
|
|
|
process, we simulate its execution by playing back the recorded
|
|
|
|
execution log. For each instruction in the log, we simulate the
|
|
|
|
instruction's side effects by duplicating the changes that it would
|
|
|
|
have made on memory and registers. */

/* This is the data structure that makes up the execution log.
|
|
|
|
|
|
|
|
The execution log consists of a single linked list of entries
|
|
|
|
of type "struct record_entry". It is doubly linked so that it
|
|
|
|
can be traversed in either direction.
|
|
|
|
|
|
|
|
The start of the list is anchored by a struct called
|
|
|
|
"record_first". The pointer "record_list" either points to the
|
|
|
|
last entry that was added to the list (in record mode), or to the
|
|
|
|
next entry in the list that will be executed (in replay mode).
|
|
|
|
|
|
|
|
Each list element (struct record_entry), in addition to next and
|
|
|
|
prev pointers, consists of a union of three entry types: mem, reg,
|
|
|
|
and end. A field called "type" determines which entry type is
|
|
|
|
represented by a given list element.
|
|
|
|
|
|
|
|
Each instruction that is added to the execution log is represented
|
|
|
|
by a variable number of list elements ('entries'). The instruction
|
|
|
|
will have one "reg" entry for each register that is changed by
|
|
|
|
executing the instruction (including the PC in every case). It
|
|
|
|
will also have one "mem" entry for each memory change. Finally,
|
|
|
|
each instruction will have an "end" entry that separates it from
|
|
|
|
the changes associated with the next instruction. */

Maybe process record should record what really happened,

So if Linux delivered the signal to the child process during

the user says something different, like "deliver this signal"

during the replay mode).
|
|
|
|

User should understand that nothing he does during the replay
|

|
mode will change the behavior of the child. If he tries,

|
then that is a user error.
|
|
|
|
|
|
|

But we should still deliver the signal to gdb during the replay,

if we delivered it during the recording. Therefore we should
