* procfs.c: Cleanup of procfs tracing. Move defines and prototypes to proc-utils.h * proc-utils.h: Define tracing macros. Declare trace functions. * proc-api.c: Make procfs tracing a runtime option. (prepare_to_trace): New function, abstracted out of several places. Open a trace file if one is required. (ioctl_with_trace, write_with_trace, open_with_trace, close_with_trace, wait_with_trace, lseek_with_trace): Report errno if an error occurs in a system call.

2000-05-052000-05-05 Michael Snyder <msnyder@seadog.cygnus.com>Michael Snyder1-15/+15
* procfs.c (many functions): change int cmd; to long cmd; Solaris /proc API calls this parameter a long, and requires it for 64-bit hosts (where sizeof(long) != sizeof(int)). UnixWare calls it an int, but on existing UnixWare hosts, int and long are the same size. So long it must be. If a future UnixWare version has problems with this, we'll have to use autoconf. * proc-api.c (write_with_trace): use long instead of int.

* procfs.c (comments): Eliminate "???" in comments, which GCC wants to interpret as a trigraph. (fill_gregset, supply_gregset, fill_fpregset, supply_fpregset): declare. (procfs_wait): Sysargs is a long, change printf format to match. (test-mapping, mapping_test, test_mapping_cmd) Remove (test only).
2000-04-07From 2000-03-27 Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:Andrew Cagney1-0/+2

* procfs.c: Added replacement macros for LWP stuff. Fixed support for UnixWare / SVR4.2MP targets and any targets which use multi-file /proc entries. Fixed support for hardware watchpoints. * solib.c: SCO needs some of the same code as SunOS.

(procfs_wait): use GETPID to get process ID. NOTE: I didn't commit Kean's changes to configure.host/configure.tgt yet because they are kind of bogus and I'm punting back to him to let him figure out what he's trying to do. So configuring for UnixWare may not work just yet.

1997-06-17 * procfs.c (proc_set_exec_trap, procfs_init_inferior, procfs_wait,Peter Schauer1-53/+7
unconditionally_kill_inferior): Undo Oct 26 1996 and Apr 26 1997 changes to trace PRFS_STOPTERM and handle PR_DEAD. These changes tried to work around a problem with an early DU 4.0 release, but they trigger subtle timing dependent kernel bugs in older OSF/1 releases.

* procfs.c (notice_signals): fix typo
1997-04-10Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>Geoffrey Noer1-179/+1051
* procfs.c: Substantial (but incomplete) changes to support sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo struct now has substructs like struct flt_ctl instead of just a fltset_t and has a ctl_fd, status_fd, as_fd, and map_fd instead of a single fd. Non-sysv4.2mp procfs models still have the structs and multiple fds, but don't use the entire struct and the four fds all point to the same thing. We use PROCFS_USE_READ_WRITE to decide whether to talk to procfs with reads/writes or use ioctl instead. We use HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has multiple fds or not. PROC_NAME_FMT is split out into CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, STATUS_PROC_NAME_FMT. (procfs_notice_signals): now a necessary wrapper around (notice_signals): which are the new guts for noticing signals (open_proc_file): gets a new flag arg used in sysv4.2mp to determine whether or not to attempt to open the ctl_fd. (procfs_read_status): new local function, reads procfs status (procfs_write_pcwstop): new local function, writes a PCWSTOP (procfs_write_pckill): new local function, writes a PCKILL (unconditionally_kill_inferior): remove signo since we now just call procfs_write_pckill(). (procfs_xfer_memory): call lseek with SEEK_SET rather than 0 (proc_iterate_over_mappings): the whole function is ifdefed on UNIXWARE to keep things readable. Expanded the syscall_table to include new potential sysv4.2mp members. Note that all ifdefs of UNIXWARE should be eliminated if possible or renamed to describe what's being selected for a bit better. Sysv4.2mp and IRIX both have SYS_sproc so the IRIX specific code now also checks it's not UNIXWARE. * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T, HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to "/debug/%d" as PROC_NAME_FMT used to be
1996-11-16 From Peter Schauer <Peter.Schauer@Regent.E-Technik.TU-Muenchen.DE>Fred Fish1-7/+10
* procfs.c (wait_fd): Handle EINTR error return from poll by restarting the poll. * defs.h (PIDGET): Define a default version that just returns its argument unchanged. * inflow.c (terminal_init_inferior): Eliminate #ifdef of PIDGET and fold both alternatives into common code. (pass_signal): Use PIDGET for pid passed to kill().
1996-10-26 * procfs.c (proc_set_exec_trap): Under Alpha OSF/1-4.0, tracingPeter Schauer1-6/+30
the entry to the exit system call to detect termination of the inferior stopped working. Trace termination of the inferior via PRFS_STOPTERM instead. (procfs_init_inferior): Do not trace entry to exit system call if PIOCSSPCACT is defined. (procfs_wait): Handle PR_DEAD event, which signals the termination of the inferior if PRFS_STOPTERM is set. * mdebugread.c (parse_partial_symbols): Ignore stNil section start address symbols. * sparc-tdep.c (get_saved_register): Get saved PC from the frame info if not in innermost frame.

config/sparc/nm-sun4sol2.h config/sparc/sun4sol2.mh config/sparc/tm-sun4sol2.h: Use autoconf to config Solaris thread and pthread support, since pre-2.5 systems don't come with libthread_db.so.1. * procfs.c (info_proc): Use int instead of id_t. Old versions of Irix don't see to define this.
1996-05-09 * Makefile.in, breakpoint.c, corelow.c, fork-child.c, inflow.c,Stu Grossman1-1/+1
infrun.c, mac-nat.c, procfs.c, remote.c, sol-thread.c, thread.c, win32-nat.c, config/nm-lynx.h: Rename thread.h to gdbthread.h to avoid conflict with Solaris /usr/include/thread.h.
