For optimization purposes many kernels don't have the

|
callee saved registers into the save_state structure upon
|
|
|
|

entry into the kernel for a syscall; the optimization
|
|
|
|
|
is usually turned off if the process is being traced so
|
|
|
|
|
that the debugger can get full register state for the
|
|
|
|
|
process.

|
|
1999-07-08 04:19:36 +08:00
|
|
|
|
* Attaching to a process when the process is in the
|
|
|
|
|
kernel performing a system call (debugger can't get
|
|
|
|
|
full register state for the inferior process since
|
|
|
|
|
the process wasn't being traced when it entered the
|
|
|
|
|
system call).

The following heinous code is an attempt to deal with

the lack of register state in a core dump. It will

fail miserably if the function which performs the

system call has a variable sized stack frame. */

This function calls shl_findsym, indirectly through a

call to __d_shl_get. __d_shl_get is in end.c, which is always
|
|
|
|
|
linked in by the hp compilers/linkers.
|
|
|
|
|
The call to shl_findsym cannot be made directly because it needs
|
|
|
|
|
to be active in target address space.
|
|
|
|
|
inputs: - minimal symbol pointer for the function we want to look up
|
|
|
|
|
- address in target space of the descriptor for the library
|
|
|
|
|
where we want to look the symbol up.
|
|
|
|
|
This address is retrieved using the
|
|
|
|
|
som_solib_get_solib_by_pc function (somsolib.c).
|
|
|
|
|
output: - real address in the library of the function.
|
|
|
|
|
note: the handle can be null, in which case shl_findsym will look for
|
|
|
|
|
the symbol in all the loaded shared libraries.

2003-05-06 01:56:57 +08:00
|
|
|
|
Therefore our version of DEPRECATED_FIX_CALL_DUMMY takes an extra
|
|
|
|
|
argument, real_pc, which is the location where gdb should start up
|
|
|
|
|
the inferior to do the function call.
|
1999-06-08 03:19:32 +08:00
|
|
|
|
|
|
|
|
|
This has to work across several versions of hpux, bsd, osf1. It has to
|
|
|
|
|
work regardless of what compiler was used to build the inferior program.
|
|
|
|
|
It should work regardless of whether or not end.o is available. It has
|
|
|
|
|
to work even if gdb can not call into the dynamic loader in the inferior
|
|
|
|
|
to query it for symbol names and addresses.
|
|
|
|
|
|
|
|
|
|
Yes, all those cases should work. Luckily code exists to handle most
|
|
|
|
|
of them. The complexity is in selecting exactly what scheme should
|
|
|
|
|
be used to perform the inferior call.
|
|
|
|
|
|
|
|
|
|
At the current time this routine is known not to handle cases where
|
|
|
|
|
the program was linked with HP's compiler without including end.o.

(FIXME): Unfortunately, we are not that lucky: it turns out that the

when it is entered (somread.c::som_symtab_read()) it can happen that

does not work. SOOOO..., even if we have a regular function w/o trampolines

its minimal symbol can be assigned type mst_solib_trampoline.

Also, if we find that the symbol is a real stub, then we fix the unwind

descriptor, and define the stub type to be EXPORT.

|
|
|
|
|
Ptrace-based gdb will always return FALSE to the thread-switch
|

|
|
|
query, and thus also to PREPARE_TO_PROCEED.
|
|
|
|
|
|
|
|
|
|
The important thing is whether there is a BPT instruction,
|
|
|
|
|
not how many user breakpoints there are. So we have to worry
|
|
|
|
|
about things like these:
|
|
|
|
|
|
|
|
|
|
o Non-bp stop -- NO
|
|
|
|
|
|
|
|
|
|
o User hits bp, no switch -- NO
|
|
|
|
|
|
|
|
|
|
o User hits bp, switches threads -- YES
|
|
|
|
|
|
|
|
|
|
o User hits bp, deletes bp, switches threads -- NO
|
|
|
|
|
|
|
|
|
|
o User hits bp, deletes one of two or more bps
|
1999-07-08 04:19:36 +08:00
|
|
|
|
at that PC, user switches threads -- YES
|
1999-04-16 09:35:26 +08:00
|
|
|
|
|
|
|
|
|
o Plus, since we're buffering events, the user may have hit a
|
1999-07-08 04:19:36 +08:00
|
|
|
|
breakpoint, deleted the breakpoint and then gotten another
|
|
|
|
|
hit on that same breakpoint on another thread which
|
|
|
|
|
actually hit before the delete. (FIXME in breakpoint.c
|
|
|
|
|
so that "dead" breakpoints are ignored?) -- NO
|
1999-04-16 09:35:26 +08:00
|
|
|
|
|
|
|
|
|
For these reasons, we have to violate information hiding and
|
|
|
|
|
call "breakpoint_here_p". If core gdb thinks there is a bpt
|
|
|
|
|
here, that's what counts, as core gdb is the one which is
|
2001-04-07 01:53:39 +08:00
|
|
|
|
putting the BPT instruction in and taking it out.
|
|
|
|
|
|
|
|
|
|
Note that this implementation is potentially redundant now that
|
2001-06-07 00:31:32 +08:00
|
|
|
|
default_prepare_to_proceed() has been added.
|
|
|
|
|
|
|
|
|
|
FIXME This may not support switching threads after Ctrl-C
|
|
|
|
|
correctly. The default implementation does support this. */

/* Sometimes we may pluck out a minimal symbol that has a negative address.
|
|
|
|
|
|
|
|
|
|
An example of this occurs when an a.out is linked against a foo.sl.
|
|
|
|
|
The foo.sl defines a global bar(), and the a.out declares a signature
|
|
|
|
|
for bar(). However, the a.out doesn't directly call bar(), but passes
|
|
|
|
|
its address in another call.
|
|
|
|
|
|
|
|
|
|
If you have this scenario and attempt to "break bar" before running,
|
|
|
|
|
gdb will find a minimal symbol for bar() in the a.out. But that
|
|
|
|
|
symbol's address will be negative. What this appears to denote is
|
|
|
|
|
an index backwards from the base of the procedure linkage table (PLT)
|
|
|
|
|
into the data linkage table (DLT), the end of which is contiguous
|
|
|
|
|
with the start of the PLT. This is clearly not a valid address for
|
|
|
|
|
us to set a breakpoint on.
|
|
|
|
|
|
|
|
|
|
Note that one must be careful in how one checks for a negative address.
|
|
|
|
|
0xc0000000 is a legitimate address of something in a shared text
|
|
|
|
|
segment, for example. Since I don't know what the possible range
|
|
|
|
|
is of these "really, truly negative" addresses that come from the
|
|
|
|
|
minimal symbols, I'm resorting to the gross hack of checking the
|
|
|
|
|
top byte of the address for all 1's. Sigh. */
