The general register and floating point register sets are manipulated by
|
|
|
|
|
separate ioctl's. This file makes the assumption that if FP0_REGNUM is
|
|
|
|
|
defined, then support for the floating point register set is desired,
|
|
|
|
|
regardless of whether or not the actual target has floating point hardware.

* README: Add note about SPARCworks cc release 3.0 and higher.
Add procfs support for Alpha OSF/1-2.x.
* config/alpha/nm-osf.h: Renamed from nm-alpha.h, generic
OSF/1 native support.
* config/alpha/alpha-osf1.mh (NAT_FILE): Changed accordingly.
(MUNCH_DEFINE): Removed.
* config/alpha/alpha-osf2.mh, config/alpha/nm-osf2.h: New files
for procfs support.
* configure.in (alpha-dec-osf*): Use alpha-osf2.mh for OSF/1
release 2.x and higher, else alpha-osf1.mh, as the procfs support
in release 1.x is incomplete.
* Makefile.in (ALLCONFIG): Add config/alpha/alpha-osf2.mh.
* alpha-nat.c (supply_gregset, fill_gregset, supply_fpgregset,
fill_fpgregset): New routines for procfs support.
* inftarg.c (_initialize_inftarg): Don't add ptrace support
if we have an optional procfs and /proc is accessible.
* procfs.c: Include sys/fault.h and sys/syscall.h before
including sys/procfs.h.
(unconditionally_kill_inferior): If PROCFS_NEED_PIOCSSIG_FOR_KILL
is defined, additionally perform a PIOCSSIG to really terminate
the inferior.
(create_procinfo): Always return a result.
(create_procinfo, do_attach): Don't trace T_IFAULT faults if
PROCFS_DONT_TRACE_IFAULT is defined.
(procfs_init_inferior): Use START_INFERIOR_TRAPS_EXPECTED as
argument to startup_inferior if it is defined.
(proc_set_exec_trap): If PIOCSSPCACT is defined, use it instead
of tracing exits from exec system calls. Needed for the user level
loader under Alpha OSF/1.
(do_detach): Clear any pending signal if we want to detach from
a process without a signal.
(set_proc_siginfo): If PROCFS_DONT_PIOCSSIG_CURSIG is defined,
don't issue a PIOCSSIG if pr_cursig already contains the signal we
intend to set.
(info_proc_signals): If PROCFS_SIGPEND_OFFSET is defined, the
pending signals are numbered from 1 instead of 0.
(info_proc_mappings): Increase size of output format for addresses
if BFD_HOST_64_BIT is defined.
(procfs_stop): Renamed from child_stop.
(_initialize_procfs): Don't add procfs support if we have an
optional procfs and /proc is not accessible.

|
|
|

DESCRIPTION
|
|
|
|
|
|
|
|
|
|
Store our current register values back into the inferior. If
|
|
|
|
|
REGNO is -1 then store all the register, otherwise store just
|
|
|
|
|
the value specified by REGNO.
|
|
|
|
|
|
|
|
|
|
NOTES
|
|
|
|
|
|
|
|
|
|
If we are storing only a single register, we first have to get all
|
|
|
|
|
the current values from the process, overwrite the desired register
|
|
|
|
|
in the gregset with the one we want from gdb's registers, and then
|
|
|
|
|
send the whole set back to the process. For writing all the
|
|
|
|
|
registers, all we have to do is generate the gregset and send it to
|
|
|
|
|
the process.
|
|
|
|
|
|
|
|
|
|
Also note that the process has to be stopped on an event of interest
|
|
|
|
|
for this to work, which basically means that it has to have been
|
|
|
|
|
run under the control of one of the other /proc ioctl calls and not
|
|
|
|
|
ptrace. Since we don't use ptrace anyway, we don't worry about this
|
|
|
|
|
fine point, but it is worth noting for future reference.
|
|
|
|
|
|
|
|
|
|
Gdb is confused about what this function is supposed to return.
|
|
|
|
|
Some versions return a value, others return nothing. Some are
|
|
|
|
|
declared to return a value and actually return nothing. Gdb ignores
|
|
|
|
|
anything returned. (FIXME)

DESCRIPTION
|
|
|
|
|
|
|
|
|
|
This routine is called when an inferior process is about to finish an
|
|
|
|
|
sproc() system call. This is the system call that IRIX uses to create
|
|
|
|
|
a lightweight process. When the target process gets this event, we can
|
|
|
|
|
look at rval1 to find the new child processes ID, and create a new
|
|
|
|
|
procinfo struct from that.
|
|
|
|
|
|
|
|
|
|
After that, it pretends that we got a SIGTRAP, and returns non-zero
|
|
|
|
|
to tell procfs_wait to wake up. Subsequently, wait_for_inferior gets
|
|
|
|
|
woken up, sees the new process and continues it.
|
|
|
|
|
|
|
|
|
|
NOTES
|
|
|
|
|
We actually never see the child exiting from sproc because we will
|
|
|
|
|
shortly stop the child with PIOCSTOP, which is then registered as the
|
|
|
|
|
event of interest.

DESCRIPTION
|
|
|
|
|
|
|
|
|
|
This routine is called when an inferior process is about to finish a
|
|
|
|
|
fork() system call. We will open up the new process, and then close
|
|
|
|
|
it, which releases it from the clutches of the debugger.
|
|
|
|
|
|
|
|
|
|
After that, we continue the target process as though nothing had
|
|
|
|
|
happened.
|
|
|
|
|
|
|
|
|
|
NOTES
|
|
|
|
|
This is necessary for IRIX because we have to set PR_FORK in order
|
|
|
|
|
to catch the creation of lwps (via sproc()). When an actual fork
|
|
|

DESCRIPTION
|
|
|
|
|
|
|
|
|
|
When gdb starts an inferior, this function is called in the parent
|
|
|
|
|
process immediately after the fork. It waits for the child to stop
|
|
|
|
|
on the return from the exec system call (the child itself takes care
|
|
|
|
|
of ensuring that this is set up), then sets up the set of signals
|
1996-05-06 23:27:37 +02:00
|
|
|
|
and faults that are to be traced. Returns the pid, which may have had
|
|
|
|
|
the thread-id added to it.

NOTES
|
|
|
|
|
|
|
|
|
|
If proc_init_failed ever gets called, control returns to the command
|
|
|
|
|
processing loop via the standard error handling code.

DESCRIPTION
|
|
|
|
|
|
|
|
|
|
When the user changes the state of gdb's signal handling via the
|
|
|
|
|
"handle" command, this function gets called to see if any change
|
|
|
|
|
in the /proc interface is required. It is also called internally
|
|
|
|
|
by other /proc interface functions to initialize the state of
|
|
|
|
|
the traced signal set.
|
|
|
|
|
|
|
|
|
|
One thing it does is that signals for which the state is "nostop",
|
|
|
|
|
"noprint", and "pass", have their trace bits reset in the pr_trace
|
|
|
|
|
field, so that they are no longer traced. This allows them to be
|
|
|
|
|
delivered directly to the inferior without the debugger ever being
|
|
|
|
|
involved.

SYNOPSIS
|
|
|
|
|
|
|
|
|
|
void proc_set_exec_trap (void)
|
|
|
|
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
|
|
|
|
|
|
This function is called in the child process when starting up
|
|
|
|
|
an inferior, prior to doing the exec of the actual inferior.
|
|
|
|
|
It sets the child process's exitset to make exit from the exec
|
|
|
|
|
system call an event of interest to stop on, and then simply
|
|
|
|
|
returns. The child does the exec, the system call returns, and
|
|
|
|
|
the child stops at the first instruction, ready for the gdb
|
|
|
|
|
parent process to take control of it.
|
|
|
|
|
|
|
|
|
|
NOTE
|
|
|
|
|
|
|
|
|
|
We need to use all local variables since the child may be sharing
|
|
|
|
|
it's data space with the parent, if vfork was used rather than
|
|
|
|
|
fork.
|
1992-04-01 21:46:14 +02:00
|
|
|
|
|
|
|
|
|
Also note that we want to turn off the inherit-on-fork flag in
|
|
|
|
|
the child process so that any grand-children start with all
|
|
|
|
|
tracing flags cleared.

|
|
|
|
Given an address of a location in the inferior, find and return

|
the base address of the mapped segment containing that address.
|
|
|
|
|
|
|
|
|
|
This is used for example, by the shared library support code,
|
|
|
|
|
where we have the pc value for some location in the shared library
|
|
|
|
|
where we are stopped, and need to know the base address of the
|
|
|
|
|
segment containing that address.

DESCRIPTION
|
|
|
|
|
|
|
|
|
|
Attach to an already existing process with the specified process
|
|
|
|
|
id. If the process is not already stopped, query whether to
|
|
|
|
|
stop it or not.
|
|
|
|
|
|
|
|
|
|
NOTES
|
|
|
|
|
|
|
|
|
|
The option of stopping at attach time is specific to the /proc
|
|
|
|
|
versions of gdb. Versions using ptrace force the attachee
|
1992-07-05 12:26:53 +02:00
|
|
|
|
to stop. (I have changed this version to do so, too. All you
|
|
|
|
|
have to do is "continue" to make it go on. -- gnu@cygnus.com)

DESCRIPTION
|
|
|
|
|
|
|
|
|
|
Detach from the current attachee.
|
|
|
|
|
|
|
|
|
|
If signal is non-zero, the attachee is started running again and sent
|
|
|
|
|
the specified signal.
|
|
|
|
|
|
|
|
|
|
If signal is zero and the attachee was not already stopped when we
|
|
|
|
|
attached to it, then we make it runnable again when we detach.
|
|
|
|
|
|
|
|
|
|
Otherwise, we query whether or not to make the attachee runnable
|
|
|
|
|
again, since we may simply want to leave it in the state it was in
|
|
|
|
|
when we attached.
|
|
|
|
|
|
|
|
|
|
We report any problems, but do not consider them errors, since we
|
|
|
|
|
MUST detach even if some things don't seem to go right. This may not
|
|
|
|
|
be the ideal situation. (FIXME).

/* emulate wait() as much as possible.

Wait for child to do something. Return pid of child, or -1 in case
|
|
|
|
|
of error; store status in *OURSTATUS.
|
|
|
|
|
|
|
|
|
|
Not sure why we can't
|
|
|
|
|
just use wait(), but it seems to have problems when applied to a
|
|
|
|
|
process being controlled with the /proc interface.
|
|
|
|
|
|
|
|
|
|
We have a race problem here with no obvious solution. We need to let
|
|
|
|
|
the inferior run until it stops on an event of interest, which means
|
|
|
|
|
that we need to use the PIOCWSTOP ioctl. However, we cannot use this
|
|
|
|
|
ioctl if the process is already stopped on something that is not an
|
|
|
|
|
event of interest, or the call will hang indefinitely. Thus we first
|
|
|
|
|
use PIOCSTATUS to see if the process is not stopped. If not, then we
|
|
|
|
|
use PIOCWSTOP. But during the window between the two, if the process
|
|
|
|
|
stops for any reason that is not an event of interest (such as a job
|
|
|
|
|
control signal) then gdb will hang. One possible workaround is to set
|
|
|
|
|
an alarm to wake up every minute of so and check to see if the process
|
|
|
|
|
is still running, and if so, then reissue the PIOCWSTOP. But this is
|
|
|
|
|
a real kludge, so has not been implemented. FIXME: investigate
|
|
|
|
|
alternatives.

SYNOPSIS
|
|
|
|
|
|
|
|
|
|
void set_proc_siginfo (struct procinfo *pip, int signo);
|
|
|
|
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
|
|
|
|
|
|
Given a pointer to a process info struct in PIP and a signal number
|
|
|
|
|
in SIGNO, set the process's current signal and its associated signal
|
|
|
|
|
information. The signal will be delivered to the process immediately
|
|
|
|
|
after execution is resumed, even if it is being held. In addition,
|
|
|
|
|
this particular delivery will not cause another PR_SIGNALLED stop
|
|
|
|
|
even if the signal is being traced.
|
|
|
|
|
|
|
|
|
|
If we are not delivering the same signal that the prstatus siginfo
|
|
|
|
|
struct contains information about, then synthesize a siginfo struct
|
|
|
|
|
to match the signal we are doing to deliver, make it of the type
|
|
|
|
|
"generated by a user process", and send this synthesized copy. When
|
|
|
|
|
used to set the inferior's signal state, this will be required if we
|
|
|
|
|
are not currently stopped because of a traced signal, or if we decide
|
|
|
|
|
to continue with a different signal.
|
|
|
|
|
|
|
|
|
|
Note that when continuing the inferior from a stop due to receipt
|
|
|
|
|
of a traced signal, we either have set PRCSIG to clear the existing
|
|
|
|
|
signal, or we have to call this function to do a PIOCSSIG with either
|
|
|
|
|
the existing siginfo struct from pr_info, or one we have synthesized
|
|
|
|
|
appropriately for the signal we want to deliver. Otherwise if the
|
|
|
|
|
signal is still being traced, the inferior will immediately stop
|
|
|
|
|
again.
|
|
|
|
|
|
|
|
|
|
See siginfo(5) for more details.

us back into the command loop.

DESCRIPTION
|
|
|
|
|
|
1992-07-05 12:26:53 +02:00
|
|
|
|
Given a process id and a mode, close the existing open /proc
|
|
|
|
|
entry (if any) and open one for the new process id, in the
|
|
|
|
|
specified mode. Once it is open, then mark the local process
|
|
|
|
|
information structure as valid, which guarantees that the pid,
|
|
|
|
|
fd, and pathname fields match an open /proc entry. Returns
|
|
|
|
|
zero if the open fails, nonzero otherwise.
|
1991-10-24 12:28:54 +01:00
|
|
|
|
|
|
|
|
|
Note that the pathname is left intact, even when the open fails,
|
|
|
|
|
so that callers can use it to construct meaningful error messages
|
|
|
|
|
rather than just "file open failed".
|
1996-05-06 23:27:37 +02:00
|
|
|
|
|
|
|
|
|
Note that for Solaris, the process-id also includes an LWP-id, so we
|
|
|
|
|
actually attempt to open that. If we are handed a pid with a 0 LWP-id,
|
|
|
|
|
then we will ask the kernel what it is and add it to the pid. Hence,
|
|
|
|
|
the pid can be changed by us.

* README: Add note about SPARCworks cc release 3.0 and higher.
Add procfs support for Alpha OSF/1-2.x.
* config/alpha/nm-osf.h: Renamed from nm-alpha.h, generic
OSF/1 native support.
* config/alpha/alpha-osf1.mh (NAT_FILE): Changed accordingly.
(MUNCH_DEFINE): Removed.
* config/alpha/alpha-osf2.mh, config/alpha/nm-osf2.h: New files
for procfs support.
* configure.in (alpha-dec-osf*): Use alpha-osf2.mh for OSF/1
release 2.x and higher, else alpha-osf1.mh, as the procfs support
in release 1.x is incomplete.
* Makefile.in (ALLCONFIG): Add config/alpha/alpha-osf2.mh.
* alpha-nat.c (supply_gregset, fill_gregset, supply_fpgregset,
fill_fpgregset): New routines for procfs support.
* inftarg.c (_initialize_inftarg): Don't add ptrace support
if we have an optional procfs and /proc is accessible.
* procfs.c: Include sys/fault.h and sys/syscall.h before
including sys/procfs.h.
(unconditionally_kill_inferior): If PROCFS_NEED_PIOCSSIG_FOR_KILL
is defined, additionally perform a PIOCSSIG to really terminate
the inferior.
(create_procinfo): Always return a result.
(create_procinfo, do_attach): Don't trace T_IFAULT faults if
PROCFS_DONT_TRACE_IFAULT is defined.
(procfs_init_inferior): Use START_INFERIOR_TRAPS_EXPECTED as
argument to startup_inferior if it is defined.
(proc_set_exec_trap): If PIOCSSPCACT is defined, use it instead
of tracing exits from exec system calls. Needed for the user level
loader under Alpha OSF/1.
(do_detach): Clear any pending signal if we want to detach from
a process without a signal.
(set_proc_siginfo): If PROCFS_DONT_PIOCSSIG_CURSIG is defined,
don't issue a PIOCSSIG if pr_cursig already contains the signal we
intend to set.
(info_proc_signals): If PROCFS_SIGPEND_OFFSET is defined, the
pending signals are numbered from 1 instead of 0.
(info_proc_mappings): Increase size of output format for addresses
if BFD_HOST_64_BIT is defined.
(procfs_stop): Renamed from child_stop.
(_initialize_procfs): Don't add procfs support if we have an
optional procfs and /proc is not accessible.

DESCRIPTION
|
|
|
|
|
|
|
|
|
|
Implement gdb's "info proc" command by using the /proc interface
|
|
|
|
|
to print status information about any currently running process.
|
|
|
|
|
|
|
|
|
|
Examples of the use of "info proc" are:
|
|
|
|
|
|
1992-04-01 21:46:14 +02:00
|
|
|
|
info proc (prints summary info for current inferior)
|
|
|
|
|
info proc 123 (prints summary info for process with pid 123)
|
|
|
|
|
info proc mappings (prints address mappings)
|
|
|
|
|
info proc times (prints process/children times)
|
|
|
|
|
info proc id (prints pid, ppid, gid, sid, etc)
|
Make the /proc support a target-struct in its own right.
* inferior.h (proc_wait, inferior_proc_init, proc_set_exec_trap):
No longer global functions.
(fork_inferior): New global function from fork-child.c.
* inftarg.c (child_wait): Remove USE_PROC_FS conditional.
(ptrace_me, ptrace_him): New stub functions for fork_inferior().
(child_create_inferior): Moved to fork-child.c as fork_inferior.
(child_create_inferior): New tiny function that calls fork_inferior.
* fork-child.c: New file, containing fork_inferior, which is
built from slight mods to inftarg.c's child_create_inferior.
* procfs.c (procfs_ops): Add target vector.
(attach): Rename as static do_attach.
(procfs_create_inferior): New tiny function that calls fork_inferior.
(child_xfer_memory): Rename to static procfs_xfer_memory.
(store_inferior_registers): Rename to static procfs_store_registers.
(inferior_proc_init): Rename to static procfs_init_inferior.
(procfs_attach, procfs_detach, procfs_prepare_to_store,
procfs_files_info, procfs_open, procfs_mourn_inferior,
procfs_can_run): Slightly mangled copies of the corresponding
child_XXX routines from inftarg.c.
(proc_wait): Renamed to static procfs_wait.
(child_resume): Rename to static procfs_resume.
(fetch_inferior_registers): Rename to static procfs_fetch_registers.
(initialize_proc_fs): Rename to initialize_procfs. Set up
procfs_ops, too.
* xm-irix4.h, xm-sysv4.h (CREATE_INFERIOR_HOOK): No longer needed.
1992-09-26 11:06:30 +02:00
|
|
|
|
FIXME: i proc id not implemented.
|
1992-04-01 21:46:14 +02:00
|
|
|
|
info proc status (prints general process state info)
|
Make the /proc support a target-struct in its own right.
* inferior.h (proc_wait, inferior_proc_init, proc_set_exec_trap):
No longer global functions.
(fork_inferior): New global function from fork-child.c.
* inftarg.c (child_wait): Remove USE_PROC_FS conditional.
(ptrace_me, ptrace_him): New stub functions for fork_inferior().

DESCRIPTION
|

|
|
|
|
1996-05-06 23:27:37 +02:00
|
|
|
|
This function sets up an entry and/or exit trap for the specified system
|
|
|
|
|
call. When the child executes the specified system call, your function
|
|
|
|
|
will be called with the call #, a flag that indicates entry or exit, and
|
|
|
|
|
pointers to rtnval and statval (which are used by procfs_wait). The
|
|
|
|
|
function should return non-zero if something interesting happened, zero
|
|
|
|
|
otherwise.

SYNOPSIS

|
DESCRIPTION
|
|
|
|
|
|
|
|
|
|
This routine is called both when an inferior process and it's new lwp
|
|
|
|
|
are about to finish a _lwp_create() system call. This is the system
|
|
|
|
|
call that Solaris uses to create a lightweight process. When the
|
|
|
|
|
target process gets this event, we can look at sysarg[2] to find the
|
|
|
|
|
new childs lwp ID, and create a procinfo struct from that. After that,
|
|
|
|
|
we pretend that we got a SIGTRAP, and return non-zero to tell
|
|
|
|
|
procfs_wait to wake up. Subsequently, wait_for_inferior gets woken up,
|
|
|
|
|
sees the new process and continues it.
|
|
|
|
|
|
|
|
|
|
When we see the child exiting from lwp_create, we just contine it,
|
|
|
|
|
since everything was handled when the parent trapped.
|
|
|
|
|
|
|
|
|
|
NOTES
|
|
|
|
|
In effect, we are only paying attention to the parent's completion of
|
|
|
|
|
the lwp_create syscall. If we only paid attention to the child
|
|
|
|
|
instead, then we wouldn't detect the creation of a suspended thread.

just do this the normal way (via execlp, which operates by

|
|
|
|
attempting an exec for each element of the PATH until it
|
|
|
|
|
finds one which succeeds), then there will be an exec for
|
|
|
|
|
each failed attempt, each of which will cause a PR_SYSEXIT
|
|
|
|
|
stop, and we won't know how to distinguish the PR_SYSEXIT's

for these failed execs with the ones for successful execs

So I can't think of anything better than to search the PATH

now. This has several disadvantages: (1) There is a race
|
|
|
|
|
condition; if we find a file now and it is deleted before we
|
|
|
|
|
exec it, we lose, even if the deletion leaves a valid file
|
|
|
|
|
further down in the PATH, (2) there is no way to know exactly
|
|
|
|
|
what an executable (in the sense of "capable of being
|
|
|
|
|
exec'd") file is. Using access() loses because it may lose
|
|
|
|
|
if the caller is the superuser; failing to use it loses if
|
|
|
|
|
there are ACLs or some such. */

* README: Add note about SPARCworks cc release 3.0 and higher.
Add procfs support for Alpha OSF/1-2.x.
* config/alpha/nm-osf.h: Renamed from nm-alpha.h, generic
OSF/1 native support.
* config/alpha/alpha-osf1.mh (NAT_FILE): Changed accordingly.
(MUNCH_DEFINE): Removed.
* config/alpha/alpha-osf2.mh, config/alpha/nm-osf2.h: New files
for procfs support.
* configure.in (alpha-dec-osf*): Use alpha-osf2.mh for OSF/1
release 2.x and higher, else alpha-osf1.mh, as the procfs support
in release 1.x is incomplete.
* Makefile.in (ALLCONFIG): Add config/alpha/alpha-osf2.mh.
* alpha-nat.c (supply_gregset, fill_gregset, supply_fpgregset,
fill_fpgregset): New routines for procfs support.
* inftarg.c (_initialize_inftarg): Don't add ptrace support
if we have an optional procfs and /proc is accessible.
* procfs.c: Include sys/fault.h and sys/syscall.h before
including sys/procfs.h.
(unconditionally_kill_inferior): If PROCFS_NEED_PIOCSSIG_FOR_KILL
is defined, additionally perform a PIOCSSIG to really terminate
the inferior.
(create_procinfo): Always return a result.
(create_procinfo, do_attach): Don't trace T_IFAULT faults if
PROCFS_DONT_TRACE_IFAULT is defined.
(procfs_init_inferior): Use START_INFERIOR_TRAPS_EXPECTED as
argument to startup_inferior if it is defined.
(proc_set_exec_trap): If PIOCSSPCACT is defined, use it instead
of tracing exits from exec system calls. Needed for the user level
loader under Alpha OSF/1.
(do_detach): Clear any pending signal if we want to detach from
a process without a signal.
(set_proc_siginfo): If PROCFS_DONT_PIOCSSIG_CURSIG is defined,
don't issue a PIOCSSIG if pr_cursig already contains the signal we
intend to set.
(info_proc_signals): If PROCFS_SIGPEND_OFFSET is defined, the
pending signals are numbered from 1 instead of 0.
(info_proc_mappings): Increase size of output format for addresses
if BFD_HOST_64_BIT is defined.
(procfs_stop): Renamed from child_stop.
(_initialize_procfs): Don't add procfs support if we have an
optional procfs and /proc is not accessible.
