22 * Since we define GNU_SOURCE in the Makefile we don't need to define
23 USE_GNU in file.c anymore
25 Fri Sep 10 04:35:16 CEST 1999 Wichert Akkerman <wakkerma@debian.org>
27 * #define USE_GNU before including file.c so we get some extra O_* flags

47 * configure.in: Allow compilation in a different directory
49 * signal.c: Use asm/reg.h and struct regs instead of pt_regs
50 so that we don't depend on asm/ptrace.h which clashes with
53 * syscall.c: Likewise.
55 Wed Aug 4 18:01:50 CEST 1999 Wichert Akkerman <wakkerma@debian.org>
57 * Syscall 94 on Linux alpha is sys_poll

116 * linux/sparc/syscall.h: Update used sparc-linux syscalls.
117 * linux/sparc/syscallent.h: Match 2.2.9 system calls.
118 * file.c: sparc-linux asm/stat.h uses dev_t etc. types,
119 so it needs strace's own copy of the stat structure.
120 * util.c: Make it compile on sparc-linux.
121 * strace.c: Fix strace -f and -ff operation on sparc-linux.
122 * signal.c: rt_sigaction has different arguments on sparc*-linux

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

168 * Change references to LINUX into linux in file.c
169 * Fix include for LDT in mem.c
171 Thu Apr 15 22:28:15 CEST 1999 Wichert Akkerman <wakkerma@debian.org>

195 * util.c (umovestr) [LINUX]: Handle Linux like SunOS4
196 instead of SVR4. That is, read a few bytes at a time

199 Fri May 31 01:48:49 1996 J. Richard Sladkey <jrs@world.std.com>
201 * version.c: Version 3.1 is released.
203 Thu May 23 01:04:43 1996 J. Richard Sladkey <jrs@world.std.com>
205 * aclocal.m4 (AC_DECL_SYS_ERRLIST): Try looking in stdio.h
206 as well since that's where glibc declares it. Go figure.
207 * signal.c (sys_sigreturn) [ALPHA]: Use sigcontext
208 instead of sigcontext_struct since glibc v5+ apparently
209 plays games with the native OS namespace.
210 From David Mosberger-Tang <davidm@AZStarNet.com>.
212 Mon May 20 23:17:14 1996 J. Richard Sladkey <jrs@world.std.com>
214 * version.c: Version 3.0.14 is released.

224 * desc.c (decode_select, sys_select, sys_oldselect) [LINUX]:
225 Handle old and new styles of argument passing for select on Linux.
226 * ioctl.c, stream.c: Conditionalize stream code on presence of
227 sys/stream.h instead of poll because glibc implements poll but
228 not the rest of the stream interface.
229 * signal.c [LINUX]: Standardize on the name sigcontext_struct.
230 (sys_sigprocmask) [ALPHA]: Handle OSF flavor which is more like
232 * term.c (term_ioctl): Use _VMIN, if present, for TC{G,S}ETA*.
233 * util.c (umoven, umovestr): Move data in long-sized chunks
234 at a time, instead of hard coding it to be 4.
235 From David Mosberger-Tang <davidm@AZStarNet.com>.
237 Mon May 20 01:19:36 1996 J. Richard Sladkey <jrs@world.std.com>

244 locally if the header is present.
246 * syscall.c (nerrnos{0,2}): Correct size computation.
248 * Makefile.in: Remove dependencies and rules relating to files
249 normally found in the os directory. Because of the new scheme we
250 don't know precisely where they come from. Sigh.
251 * signalent.sh: Make it work for sunos4, linux, and svr4.
252 * {sunos4,linux{,/alpha},svr4}/Makefile.in: Make rules correspond
253 to traditional make syntax. Add signalent.h to files which can
254 unconditionally be rebuilt. Prevent signalent.h from being
255 unconditionally being rebuilt since it's customized.
256 * {sunos4,linux{,/alpha},svr4}/{ioctlent,errnoent,signalent}.h:
257 Use versions built by {ioctlent,errnoent,signaltent}.sh.
258 * sunos4/ioctlent.sh: Work around sprintf troubles with SunOS

266 and maintainer-clean rules.
267 * defs.h, ioctlsort.c: Make ioctl code member unsigned.
268 * ioctl.c, ioctlsort.c (compare): Perform explicit checking
269 for less, greater, and equal since subtraction on two's
270 complement numbers isn't an order relation (it isn't transitive)!
271 * linux/Makefile.in: Add rules for the signalent.h file.
272 * linux/alpha/Makefile.in: New file.
274 Sun May 19 01:12:28 1996 J. Richard Sladkey <jrs@world.std.com>

291 and sizeof(long) != sizeof(int).
292 From Richard Henderson <richard@twiddle.tamu.edu>

302 * linux/dummy.h: Handle missing library support for {send,recv}msg.
303 Reported by Thomas Bogendoerfer <tsbogend@bigbug.franken.de>.
305 * linux/syscall.h (sys_utimes): Fix a typo in the declaration.
306 From Thomas Bogendoerfer <tsbogend@bigbug.franken.de>.
308 Fri May 17 00:50:06 1996 J. Richard Sladkey <jrs@world.std.com>
310 * version.c: Version 3.0.10 is released.
312 * Makfile.in: Add os/arch to includes so that a given arch
313 (like alpha) can override the native arch (like i386).
314 * configure.in: Check for sendmsg.
316 * net.c: Make sendmsg and recvmsg dependent on an autoconf
317 test. Reported by Michael E Chastain <mec@duracef.shout.net>.

324 osf_statfs and osf_fstatfs for the alpha. Make damn sure
325 major and minor results are suitable for passing to printf.
326 * signal.c, syscall.c: Support the alpha.
327 * process.c: Add alpha user offsets.
328 * most files: Use %l? for printf arguments since
329 most are now longs for the alpha.

332 From Thomas Bogendoerfer <tsbogend@bigbug.franken.de>.

366 * sunos4/syscallent.h, svr4/syscallent.h: Fill in the new
