454 + some layout and other minor fixes

482 Thu Apr 15 22:28:15 CEST 1999 Wichert Akkerman <wakkerma@debian.org>

512 * version.c: Version 3.1 is released.
514 Thu May 23 01:04:43 1996 J. Richard Sladkey <jrs@world.std.com>
516 * aclocal.m4 (AC_DECL_SYS_ERRLIST): Try looking in stdio.h
517 as well since that's where glibc declares it. Go figure.
518 * signal.c (sys_sigreturn) [ALPHA]: Use sigcontext
519 instead of sigcontext_struct since glibc v5+ apparently
520 plays games with the native OS namespace.
521 From David Mosberger-Tang <davidm@AZStarNet.com>.
523 Mon May 20 23:17:14 1996 J. Richard Sladkey <jrs@world.std.com>

1026 to MAP_FIXED instead of MAP_ANONYMOUS.
1027 From Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>.
1029 * signal.c [LINUX] (signalent): Signal 30 is now SIGPWR.

1032 Mon Dec 5 01:05:46 1994 Rick Sladkey <jrs@world.std.com>
1034 * defs.h (tprintf): Fix typo in non-gcc ansi prototype for tprintf.
1035 Reported by Thanh Ma <tma@encore.com>.
1037 * strace.c (cleanup): Send SIGCONT before SIGTERM because Linux
1038 1.1.62 doesn't continue a traced child when the parent exits.
1039 Reported by Matt Day <mday@artisoft.com>.
1041 * system.c [LINUX]: Include netinet/in.h before arpa/inet.h.
1043 * util.c (printstr): Fix longstanding bug in notating string
1046 * strace.c [SVR4] (proc_open): Specifically wait for the child the
1047 child to go into the execve syscall to avoid spurious traces.
1048 [LINUX] (detach): Conditionalize the status variable.
1050 Sun Dec 4 23:21:42 1994 Rick Sladkey <jrs@world.std.com>
1052 * Makefile.in: Add mips arch.
1053 * acconfig.h (MIPS): Add mips define.
1054 * configure.in: Add detection of opsys irix5 and arch mips. Check
1056 Check for sys/sysconfig.h header.
1057 * defs.h (MAX_ARGS): Bump maximum syscall arguments from 8 to 32.
1058 * file.c [SVR4]: Include sys/cred.h.
1059 (access_flags): Update access flags for SGI.
1060 (sprinttime): Change type of sprinttime argument from unsigned
1062 * process.c [HAVE_PRCTL]: Include sys/prctl.h.
1063 [HAVE_PRCTL] (prctl_options, sys_prctl): New for SGI.
1064 (printsiginfo): Conditionally compile SI_TIMER and SI_MESGQ.
1065 Cast si_band member to long before printing.
1066 * signal.c (sigact_flags): Add _SA_BSDCALL for SGI.
1067 (sigprocmaskcmds): Add SIG_SETMASK32 for SGI.
1068 * strace.c [SVR4] [MIPS]:
1069 (foobar): New dummy signal handler.
1070 (main): Install a dummy signal handler in the child before pausing
1071 to work around an SGI bug in PRSABORT.
1072 (proc_open): Send a interrupt to the child instead of aborting the
1073 syscall which doesn't work on Irix5.2.
1074 * svr4/dummy.h: Add new unfinished SGI syscalls
1075 (e.g. sys_sysmp, sys_sginap, etc.). Handle some SGI syscalls like
1076 existing calls (e.g. sys_ksigaction like sys_sigaction).
1077 Printargs does the print thing for sys_sethostid.
1078 * svr4/syscall.h: Declare all new SGI syscalls.
1079 (SGI_KLUDGE): Define syscall table starting index to be 1 for SGI
1080 and add it to all subcall entry points.
1081 (SYS_pgrpsys_subcall, SYS_sigcall_subcall, SYS_context): Don't
1082 decode as subcalls on MIPS. Instead, use the normal syscalls.
1083 * svr4/syscallent.h [MIPS]: Lead syscall table with a dummy entry
1084 since SGI syscall numbers are off by one.
1085 [MIPS] (sys_pgrpsys): Rename to sys_setpgrp on SGI.
1086 [MIPS] (sys_xenix): Rename to sys_syssgi on SGI.
1087 [MIPS] (sys_sysmachine): Rename to sys_sysmips on SGI.
1088 [MIPS]: Conditionalize SVR4 extension into SGI and Solaris classes.
1089 * syscall.c (dumpio): Validate descriptor against MAX_QUALS.
1090 [HAVE_PR_SYSCALL] (syscall): Conditionalize SYS_vfork.
1091 [MIPS] (syscall): Add SGI section for decoding u_error and u_rval.
1092 Add workaround for broken SGI pr_sysarg on syscall entry.
1093 [SVR4] (syscall): Conditionalize subcall decoding for
1094 SYS_ptrpsys_subcall, SYS_sigcall_subcall and SYS_context_subcall.
1095 [SVR4] [MIPS] (getrval2): Handle SGI.
1096 * syscallent.sh: Dork the sed line to be choosier about SYS_ lines.
1097 * system.c [HAVE_SYSCONFIG_H]: Include sys/sysconfig.h.
1098 [MIPS] (syssgi_options, sys_syssgi): New for SGI.
