- waiting inline. If using_thread_db, do not call update_stop_threads
- and do not turn on linuxthreads_debug.

- state, so that it can be shared with the lin-thread.c module.
- (_initialize_linuxthreads): use linuxthreads_wait_mask to block

- will call sigsuspend when it wants to wait for this signal.
- (thread_attach): abstract out ptrace attach to share with lin-thread.c

-1999-11-01 Fernando Nasser <fnasser@totem.to.cygnus.com>
-
- From Grant Edwards <grante@visi.com>:
- * remote-rdi.c (_initialize_remote_rdi): Added command
- rdilogenable. Allows the user to log ADP packets that are
- exchanged between gdb and the target. Both the raw packets are
- shown and some minimal decoding is attempted. Default state is
- disabled.
- (_initialize_remote_rdi): Added command rdilogfile. Allows the
- user to specify the filename to which the ADP packet log is to be
- written. Default state is "rdi.log".
- (rdilogenable_command): New function. Related to rdilogenable.
- (rdilogfile_command): New function. Related to rdilogfile.
- * rdi-share/devsw.c (openLogFile, closeLogFile,
- DevSW_SetLogEnable, DevSW_SetLogfile, dumpPacket): New

- * rdi-share/hostchan.h: Add prototypes for the above functions.
-
-1999-11-01 Fernando Nasser <fnasser@totem.to.cygnus.com>
-
- From Grant Edwards <grante@visi.com>:
- * remote-rdi.c (arm_rdi_open): Added code to split the arguments
- to the 'target rdi' command at the first space. The first word is
- passed to Adp_OpenDevice as the device name, the tail is passed as
- the "arguments" parameter. This allows user specified baud rates
- -- among other things that still need to be documented [e.g. (gdb)
- target rdi /dev/ttyS1 19200]. NB: With very limited testing, the
- ARM Embedded-ICE seems to run at 19.2K (though it is reported to
- be unreliable above 9600), and the EPI Jeeni seems to run at
- 38.4K.
-
-1999-11-01 Fernando Nasser <fnasser@totem.to.cygnus.com>
-
- From Grant Edwards <grante@visi.com>:
- * remote-rdi.c (_initialize_remote_rdi): Added the boolean
- set/show variable rdiromatzero. Should be set to true if the
- target has ROM at address 0. If true, then gdb will not tell the
- target to trap fetches to interrupt vectors (which are located at
- address 0). Using the Angel monitor, attempting to set
- breakpoints in ROM is an error. Using JTAG debugging of the
- ARM7TDMI, attempting to set more than two breakpoints in ROM is an
- error. Default state is false (vectors will be trapped) -- used to
- be hardwired false.
-
-1999-11-01 Fernando Nasser <fnasser@totem.to.cygnus.com>
-
- From Grant Edwards <grante@visi.com>:
- * remote-rdi.c (_initialize_remote_rdi): Added the boolean
- set/show variable rdiheartbeat. This enables or disables ADP
- link-check "heartbeat" packets sent by the host to the target.
- Heartbeat packets can cause both the ARM Embedded-ICE and the EPI
- Jeeni to malfunction: If a heartbeat packet is received by the
- target while it is sending a packet, that packet will be aborted,
- and the ADP protocol engine then gets very confused. Default state
- is off -- used to hardwired on.

- Hardware watchpoint fix from Eli Zaretskii <eliz@gnu.org>:
-
- * breakpoint.c (insert_breakpoints): Fetch the value of the

- we need to fetch it now, before we start the inferior again.
- (insert_breakpoints, remove_breakpoint, bpstat_stop_status,
- can_use_hardware_watchpoint): Only those values representing

+ state, so that it can be shared with the lin-thread.c module.
+ (_initialize_linuxthreads): use linuxthreads_wait_mask to block

+ will call sigsuspend when it wants to wait for this signal.
+ (thread_attach): abstract out ptrace attach to share with lin-thread.c

+
+ From Grant Edwards <grante@visi.com>:
+ * remote-rdi.c (_initialize_remote_rdi): Added command
+ rdilogenable. Allows the user to log ADP packets that are
+ exchanged between gdb and the target. Both the raw packets are
+ shown and some minimal decoding is attempted. Default state is
+ disabled.
+ (_initialize_remote_rdi): Added command rdilogfile. Allows the
+ user to specify the filename to which the ADP packet log is to be
+ written. Default state is "rdi.log".
+ (rdilogenable_command): New function. Related to rdilogenable.
+ (rdilogfile_command): New function. Related to rdilogfile.

+
+1999-11-01 Fernando Nasser <fnasser@totem.to.cygnus.com>
+
+ From Grant Edwards <grante@visi.com>:
+ * remote-rdi.c (arm_rdi_open): Added code to split the arguments
+ to the 'target rdi' command at the first space. The first word is
+ passed to Adp_OpenDevice as the device name, the tail is passed as
+ the "arguments" parameter. This allows user specified baud rates
+ -- among other things that still need to be documented [e.g. (gdb)
+ target rdi /dev/ttyS1 19200]. NB: With very limited testing, the
+ ARM Embedded-ICE seems to run at 19.2K (though it is reported to
+ be unreliable above 9600), and the EPI Jeeni seems to run at
+ 38.4K.
+
+1999-11-01 Fernando Nasser <fnasser@totem.to.cygnus.com>
+
+ From Grant Edwards <grante@visi.com>:
+ * remote-rdi.c (_initialize_remote_rdi): Added the boolean
+ set/show variable rdiromatzero. Should be set to true if the
+ target has ROM at address 0. If true, then gdb will not tell the
+ target to trap fetches to interrupt vectors (which are located at
+ address 0). Using the Angel monitor, attempting to set
+ breakpoints in ROM is an error. Using JTAG debugging of the
+ ARM7TDMI, attempting to set more than two breakpoints in ROM is an
+ error. Default state is false (vectors will be trapped) -- used to
+ be hardwired false.
+
+1999-11-01 Fernando Nasser <fnasser@totem.to.cygnus.com>
+
+ From Grant Edwards <grante@visi.com>:
+ * remote-rdi.c (_initialize_remote_rdi): Added the boolean
+ set/show variable rdiheartbeat. This enables or disables ADP
+ link-check "heartbeat" packets sent by the host to the target.
+ Heartbeat packets can cause both the ARM Embedded-ICE and the EPI
+ Jeeni to malfunction: If a heartbeat packet is received by the
+ target while it is sending a packet, that packet will be aborted,
+ and the ADP protocol engine then gets very confused. Default state
+ is off -- used to hardwired on.

+
+ Hardware watchpoint fix from Eli Zaretskii <eliz@gnu.org>:

+ we need to fetch it now, before we start the inferior again.
+ (insert_breakpoints, remove_breakpoint, bpstat_stop_status,
+ can_use_hardware_watchpoint): Only those values representing

+ * PROCFS.C
+ *
+ * This module provides the interface between GDB and the
+ * /proc file system, which is used on many versions of Unix
+ * as a means for debuggers to control other processes.
+ * Examples of the systems that use this interface are:
+ * Irix
+ * Solaris
+ * OSF
+ * Unixware
+ *
+ * /proc works by immitating a file system: you open a simulated file
+ * that represents the process you wish to interact with, and
+ * perform operations on that "file" in order to examine or change
+ * the state of the other process.
+ *
+ * The most important thing to know about /proc and this module
+ * is that there are two very different interfaces to /proc:
+ * One that uses the ioctl system call, and
+ * another that uses read and write system calls.
+ * This module has to support both /proc interfaces. This means
+ * that there are two different ways of doing every basic operation.
+ *
+ * In order to keep most of the code simple and clean, I have
+ * defined an interface "layer" which hides all these system calls.
+ * An ifdef (NEW_PROC_API) determines which interface we are using,
+ * and most or all occurrances of this ifdef should be confined to
+ * this interface layer.

+ *
+ * NEW_PROC_API (Solaris 2.6, Solaris 2.7, Unixware):
+ * There are several file descriptors that may need to be open
+ * for any given process or LWP. The ones we're intereted in are:
+ * - control (ctl) write-only change the state
+ * - status (status) read-only query the state
+ * - address space (as) read/write access memory
+ * - map (map) read-only virtual addr map
+ * Most of these are opened lazily as they are needed.
+ * The pathnames for the 'files' for an LWP look slightly
+ * different from those of a first-class process:
+ * Pathnames for a process (<proc-id>):
+ * /proc/<proc-id>/ctl
+ * /proc/<proc-id>/status
+ * /proc/<proc-id>/as
+ * /proc/<proc-id>/map
+ * Pathnames for an LWP (lwp-id):
+ * /proc/<proc-id>/lwp/<lwp-id>/lwpctl
+ * /proc/<proc-id>/lwp/<lwp-id>/lwpstatus
+ * An LWP has no map or address space file descriptor, since
+ * the memory map and address space are shared by all LWPs.
+ *
+ * Everyone else (Solaris 2.5, Irix, OSF)
+ * There is only one file descriptor for each process or LWP.
+ * For convenience, we copy the same file descriptor into all
+ * three fields of the procinfo struct (ctl_fd, status_fd, and
+ * as_fd, see NEW_PROC_API above) so that code that uses them
+ * doesn't need any #ifdef's.
+ * Pathname for all:
+ * /proc/<proc-id>
+ *
+ * Solaris 2.5 LWP's:
+ * Each LWP has an independent file descriptor, but these
+ * are not obtained via the 'open' system call like the rest:
+ * instead, they're obtained thru an ioctl call (PIOCOPENLWP)
+ * to the file descriptor of the parent process.
+ *
+ * OSF threads:
+ * These do not even have their own independent file descriptor.
+ * All operations are carried out on the file descriptor of the
+ * parent process. Therefore we just call open again for each
+ * thread, getting a new handle for the same 'file'.

- LOCAL FUNCTION
-
- procfs_store_registers -- copy register values back to inferior
-
- SYNOPSIS
-
- void procfs_store_registers (int regno)
-
- 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.

-
- We have a race problem here with no obvious solution. We need to let

- 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

- LOCAL FUNCTION
-
- set_proc_siginfo - set a process's current signal info
-
- 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 going 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.

- 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.
+ /* If pi is GDB's child, wait for it to die. */
+ if (parent_pid == getpid ())
+ /* FIXME: should we use waitpid to make sure we get the right event?
+ Should we check the returned event? */
