132 Fri Sep 10 04:35:16 CEST 1999 Wichert Akkerman <wakkerma@debian.org>
134 * #define USE_GNU before including file.c so we get some extra O_* flags

154 * configure.in: Allow compilation in a different directory
156 * signal.c: Use asm/reg.h and struct regs instead of pt_regs
157 so that we don't depend on asm/ptrace.h which clashes with
160 * syscall.c: Likewise.
162 Wed Aug 4 18:01:50 CEST 1999 Wichert Akkerman <wakkerma@debian.org>

223 * linux/sparc/syscall.h: Update used sparc-linux syscalls.
224 * linux/sparc/syscallent.h: Match 2.2.9 system calls.
225 * file.c: sparc-linux asm/stat.h uses dev_t etc. types,
226 so it needs strace's own copy of the stat structure.
227 * util.c: Make it compile on sparc-linux.

250 + some layout and other minor fixes
251 + add some m68k-specific things to linux/syscallent.h. Note that m68k

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

302 * util.c (umovestr) [LINUX]: Handle Linux like SunOS4
303 instead of SVR4. That is, read a few bytes at a time
304 to avoid overrunning the end of the stack.
306 Fri May 31 01:48:49 1996 J. Richard Sladkey <jrs@world.std.com>
308 * version.c: Version 3.1 is released.
310 Thu May 23 01:04:43 1996 J. Richard Sladkey <jrs@world.std.com>
312 * aclocal.m4 (AC_DECL_SYS_ERRLIST): Try looking in stdio.h
313 as well since that's where glibc declares it. Go figure.
314 * signal.c (sys_sigreturn) [ALPHA]: Use sigcontext
315 instead of sigcontext_struct since glibc v5+ apparently
316 plays games with the native OS namespace.
317 From David Mosberger-Tang <davidm@AZStarNet.com>.
319 Mon May 20 23:17:14 1996 J. Richard Sladkey <jrs@world.std.com>
321 * version.c: Version 3.0.14 is released.

330 sys/filio.h and sys/stream.h and remove check for poll.
331 * desc.c (decode_select, sys_select, sys_oldselect) [LINUX]:
332 Handle old and new styles of argument passing for select on Linux.
333 * ioctl.c, stream.c: Conditionalize stream code on presence of
334 sys/stream.h instead of poll because glibc implements poll but
335 not the rest of the stream interface.
336 * signal.c [LINUX]: Standardize on the name sigcontext_struct.
337 (sys_sigprocmask) [ALPHA]: Handle OSF flavor which is more like
339 * term.c (term_ioctl): Use _VMIN, if present, for TC{G,S}ETA*.
340 * util.c (umoven, umovestr): Move data in long-sized chunks
341 at a time, instead of hard coding it to be 4.
342 From David Mosberger-Tang <davidm@AZStarNet.com>.
344 Mon May 20 01:19:36 1996 J. Richard Sladkey <jrs@world.std.com>

349 * signal.c [HAVE_ASM_SIGCONTEXT_H]: Conditionally include
350 asm/sigcontext.h to define sigcontext_struct and don't define it
351 locally if the header is present.
353 * syscall.c (nerrnos{0,2}): Correct size computation.
355 * Makefile.in: Remove dependencies and rules relating to files
356 normally found in the os directory. Because of the new scheme we
357 don't know precisely where they come from. Sigh.
358 * signalent.sh: Make it work for sunos4, linux, and svr4.
359 * {sunos4,linux{,/alpha},svr4}/Makefile.in: Make rules correspond
360 to traditional make syntax. Add signalent.h to files which can
361 unconditionally be rebuilt. Prevent signalent.h from being
362 unconditionally being rebuilt since it's customized.
363 * {sunos4,linux{,/alpha},svr4}/{ioctlent,errnoent,signalent}.h:
364 Use versions built by {ioctlent,errnoent,signaltent}.sh.
365 * sunos4/ioctlent.sh: Work around sprintf troubles with SunOS
368 Sun May 19 17:14:09 1996 J. Richard Sladkey <jrs@world.std.com>

372 * Makefile.in, linux/Makefile.in: Rewrite clean, distclean,
373 and maintainer-clean rules.
374 * defs.h, ioctlsort.c: Make ioctl code member unsigned.
375 * ioctl.c, ioctlsort.c (compare): Perform explicit checking
376 for less, greater, and equal since subtraction on two's
377 complement numbers isn't an order relation (it isn't transitive)!
378 * linux/Makefile.in: Add rules for the signalent.h file.
379 * linux/alpha/Makefile.in: New file.
381 Sun May 19 01:12:28 1996 J. Richard Sladkey <jrs@world.std.com>

391 * defs.h, syscall.c, ioctl.c, signal.c: Make sysent, errnoent,
392 ioctlent, and signalent indirect pointers and redirect them
393 based on personality.
394 * {sunos4,svr4,linux{,/alpha}}/signalent.h: New files.
395 Suggested by Tom Dyas <tdyas@eden.rutgers.edu>.
397 * util.c (upeek): Handle case where ptrace returns a long
398 and sizeof(long) != sizeof(int).
399 From Richard Henderson <richard@twiddle.tamu.edu>
401 Fri May 17 21:03:36 1996 J. Richard Sladkey <jrs@world.std.com>

405 * many files: Fix more printf warnings for other platforms.
407 * ipc.c (sys_msgrcv) [LINUX]: Conditionalize definition of ipc_wrapper.
409 * linux/dummy.h: Handle missing library support for {send,recv}msg.
410 Reported by Thomas Bogendoerfer <tsbogend@bigbug.franken.de>.
412 * linux/syscall.h (sys_utimes): Fix a typo in the declaration.
413 From Thomas Bogendoerfer <tsbogend@bigbug.franken.de>.
415 Fri May 17 00:50:06 1996 J. Richard Sladkey <jrs@world.std.com>
417 * version.c: Version 3.0.10 is released.
419 * Makfile.in: Add os/arch to includes so that a given arch
420 (like alpha) can override the native arch (like i386).
421 * configure.in: Check for sendmsg.
423 * net.c: Make sendmsg and recvmsg dependent on an autoconf
424 test. Reported by Michael E Chastain <mec@duracef.shout.net>.
426 * acconfig.h, configure.in: Detect the alpha.
427 * ioctl.c: Handle the alpha.
428 * defs.h: Make some members long for the alpha. Define
429 some register nicknames. Add support for WAITEXECVE.
430 * file.c [ALPHA]: Support the alpha for statfs. Add
431 osf_statfs and osf_fstatfs for the alpha. Make damn sure
432 major and minor results are suitable for passing to printf.
433 * signal.c, syscall.c: Support the alpha.
434 * process.c: Add alpha user offsets.
435 * most files: Use %l? for printf arguments since
436 most are now longs for the alpha.
437 * linux/alpha/{errnoent.h,ioctlent.{h,sh},syscallent.h}:
439 From Thomas Bogendoerfer <tsbogend@bigbug.franken.de>.

471 * Makefile.in (distclean): Fix it for subdirectories.
473 * sunos4/syscallent.h, svr4/syscallent.h: Fill in the new
