to see one of these when an exec() has happened, is if the user

caught a vfork, and then said "finish". Ordinarily a finish just
|
|
|
|
|
carries them to the call-site of the current callee, by setting
|
|
|
|
|
a temporary bp there and resuming. But in this case, the finish
|
|
|
|
|
will carry them entirely through the vfork & exec.
|

|
|
|
|
|

We don't want to allow a bp_finish to remain inserted now. But
|
|
|

we can't safely delete it, 'cause finish_command has a handle to
|
|
|
|
|
the bp on a bpstat, and will later want to delete it. There's a
|
|
|
|
|
chance (and I've seen it happen) that if we delete the bp_finish
|

|
|
|
here, that its storage will get reused by the time finish_command

gets 'round to deleting the "use to be a bp_finish" breakpoint.

We really must allow finish_command to delete a bp_finish.

In the absense of a general solution for the "how do we know
|

|
|
it's safe to delete something others may have handles to?"
|
|
|
|
|
problem, what we'll do here is just uninsert the bp_finish, and
|
|
|
|
|
let finish_command delete it.
|
|
|
|
|
|
|
|
|
|
(We know the bp_finish is "doomed" in the sense that it's
|
|
|
|
|
momentary, and will be deleted as soon as finish_command sees
|
|
|
|
|
the inferior stopped. So it doesn't matter that the bp's
|
|
|

address is probably bogus in the new a.out, unlike e.g., the

solib breakpoints.) */

after stopping, the check for whether to step over a breakpoint

there's a partial ordering, priority-like, of the actions. Once
|
|
|
|
|
you've decided that some action is appropriate, you'll never go
|
|
|
|
|
back and decide something of a lower priority is better. The
|
|
|
|
|
ordering is:
|
|
|
|
|
|
2000-10-27 17:02:42 +02:00
|
|
|
|
kc < clr sgl shl shlr slr sn sr ss ts
|
1999-07-07 22:19:36 +02:00
|
|

|
sgl < clrs shl shlr slr sn sr ss ts
|
|
|

slr < err shl shlr sn sr ss ts

|
|

|
clr < clrs err shl shlr sn sr ss ts

sn < shl shlr sr ts

shl < shlr

What I think this means is that we don't need a damned table

here. If you just put the rows and columns in the right order,

|
|

it'd look awfully regular. We could simply walk the bpstat list
|
|
|

and choose the highest priority action we find, with a little
|
|
|
|
|
logic to handle the 'err' cases, and the CLEAR_LONGJMP_RESUME/
|
|
|
|
|
CLEAR_LONGJMP_RESUME_SINGLE distinction (which breakpoint.h says
|
|
|
|
|
is messy anyway). */

memory contents, and values computed from them within GDB. If we
|
|
|
|
|
find any register references or function calls, we can't use a
|
|
|
|
|
hardware watchpoint.
|
|
|
|
|
|
|
|
|
|
The idea here is that evaluating an expression generates a series
|
|
|
|
|
of values, one holding the value of every subexpression. (The
|
|
|
|
|
expression a*b+c has five subexpressions: a, b, a*b, c, and
|
|
|
|
|
a*b+c.) GDB's values hold almost enough information to establish
|
|
|
|
|
the criteria given above --- they identify memory lvalues,
|
|
|
|
|
register lvalues, computed values, etcetera. So we can evaluate
|
|
|
|
|
the expression, and then scan the chain of values that leaves
|
|
|
|
|
behind to decide whether we can detect any possible change to the
|
|
|
|
|
expression's final value using only hardware watchpoints.
|
|
|
|
|
|
|
|
|
|
However, I don't think that the values returned by inferior
|
|
|
|
|
function calls are special in any way. So this function may not
|
|
|
|
|
notice that an expression involving an inferior function call
|
|
|
|
|
can't be watched with hardware watchpoints. FIXME. */

One example of this happening is a watchpoint's scope bp. When the
|
|
|
|
|
scope bp triggers, we notice that the watchpoint is out of scope, and
|
|
|
|
|
delete it. We also delete its scope bp. But the scope bp is marked
|
|
|
|
|
"auto-deleting", and is already on a bpstat. That bpstat is then
|
|
|
|
|
checked for auto-deleting bp's, which are deleted.
|
|
|
|
|
|
|
|
|
|
A real solution to this problem might involve reference counts in bp's,
|
|
|
|
|
and/or giving them pointers back to their referencing bpstat's, and
|
|
|
|
|
teaching delete_breakpoint to only free a bp's storage when no more
|
|
|
|
|
references were extent. A cheaper bandaid was chosen. */
