|
|---|
| 13 | --------------------------------
|
|---|
| 14 |
|
|---|
| 15 | New features:
|
|---|
| 16 |
|
|---|
| 17 | o setitimer/alarm implementation. Needs some review later
|
|---|
| 18 | the accuracy isn't extacly great.
|
|---|
| 19 |
|
|---|
| 20 | o Added a couple of missing os2emx.h features.
|
|---|
| 21 |
|
|---|
| 22 | o Some more 16-bit thunkers.
|
|---|
| 23 |
|
|---|
| 24 | Bug fixes:
|
|---|
| 25 |
|
|---|
| 26 | o Select worker called wrong tcpip function.
|
|---|
| 27 |
|
|---|
| 28 | o Incorrect assertion during thread destruction.
|
|---|
| 29 |
|
|---|
| 30 | o Fixed broken chdir and getdrive.
|
|---|
| 31 |
|
|---|
| 32 | o Improved deadlock detection (fmutex have changed,
|
|---|
| 33 | thus stdio FILE is also changed).
|
|---|
| 34 |
|
|---|
| 35 | o ...
|
|---|
| 36 |
|
|---|
| 37 |
|
|---|
| 38 | Known Limitiations/Problems:
|
|---|
| 39 |
|
|---|
| 40 | o Static linking not possible - will be fixed.
|
|---|
| 41 |
|
|---|
| 42 | o Job control will only be applied to thread 1 in a process.
|
|---|
| 43 | This won't change.
|
|---|
| 44 |
|
|---|
| 45 | o Missing some process group interfaces required for
|
|---|
| 46 | job control. They'll show up soon.
|
|---|
| 47 |
|
|---|
| 48 | o Doesn't evaluate trailing slash in paths as directory
|
|---|
| 49 | specifier, it's currently ignored.

| 53 | GCC v3.3.5 / LIBC v0.6 - Alpha 3:
|
|---|
| 54 | ---------------------------------
|
|---|
| 55 |
|
|---|
| 56 | This release have been timebombed and will stop working at the
|
|---|
| 57 | end of December 2004. The reason for this is that data structures
|
|---|
| 58 | shared between LIBC 0.6 and all future LIBC versions are not yet
|
|---|
| 59 | quite finalized. (For your comfort the timebomb will go away when
|
|---|
| 60 | the betas start, and this is the last planned LIBC v0.6 alpha.)
|
|---|
| 61 |
|
|---|
| 62 |
|
|---|
| 63 | New Features:
|
|---|
| 64 |
|
|---|
| 65 | o Updated GCC to version 3.3.5.
|
|---|
| 66 |
|
|---|
| 67 | o Replaced the signal implementation. The new implementation
|
|---|
| 68 | is much closer to the POSIX specs and implements a lot of
|
|---|
| 69 | new interfaces.
|
|---|
| 70 |
|
|---|
| 71 | o Experimental delayed loading import libraries. emximp have
|
|---|
| 72 | a new -l option for generating such libraries. At present
|
|---|
| 73 | emximp can only generate a.out libraries of this kind - so
|
|---|
| 74 | use emxomf to convert to OMF.
|
|---|
| 75 |
|
|---|
| 76 | o The dlfcn.h functions are in LIBC now.
|
|---|
| 77 |
|
|---|
| 78 | o New functions:
|
|---|
| 79 | getgrouplist(), initgroups(), memalign(), valloc(),
|
|---|
| 80 | mprotect(), _signal_os2(), _signal_sysv(),
|
|---|
| 81 | __sigpause_bsd(), bsd_signal(), killpg(), psignal(),
|
|---|
| 82 | sigaltstack(), sigblock(), sighold(), sigignore(),
|
|---|
| 83 | siginterrupt(), sigpause(), sigrelse(), sigsetmask(),
|
|---|
| 84 | sigtimedwait(), sigvec(), sigwait(), sigwaitinfo(),
|
|---|
| 85 | sigqueue(), sigset(), getgrgid(), getpwnam(),
|
|---|
| 86 | getpwuid(), setegid(), seteuid(), setregid(),
|
|---|
| 87 | setresgid(), setresuid(), setreuid(),
|
|---|
| 88 | setrgid(), setruid(), waitid(), wait3(),
|
|---|
| 89 | wait4() and getopt_long_only().
|
|---|
| 90 |
|
|---|
| 91 |
|
|---|
| 92 | Bug fixes;
|
|---|
| 93 |
|
|---|
| 94 | o Sockets were broken on some systems. Hopefully, this
|
|---|
| 95 | should be corrected now.
|
|---|
| 96 |
|
|---|
| 97 | o stat() failed on a file open for writing.
|
|---|
| 98 |
|
|---|
| 99 | o fork() didn't work for processes which allocated lot's
|
|---|
| 100 | of memory. Fixed incorrect syncing of memory objects.
|
|---|
| 101 |
|
|---|
| 102 | o ...
|
|---|
| 103 |
|
|---|
| 104 |
|
|---|
| 105 | Known Limitiations/Problems:
|
|---|
| 106 |
|
|---|
| 107 | o Static linking not possible - will be fixed.
|
|---|
| 108 |
|
|---|
| 109 | o alarm() is still missing. Code is 80% done but didn't
|
|---|
| 110 | make it for the release.
|
|---|
| 111 |
|
|---|
| 112 | o Job control will only be applied to thread 1 in a process.
|
|---|
| 113 | This won't change.
|
|---|
| 114 |
|
|---|
| 115 | o Missing some process group interfaces required for
|
|---|
| 116 | job control. They'll show up soon.
|
|---|
| 117 |
|
|---|
| 118 |
|
|---|
| 119 |
|
|---|
| 120 | GCC v3.3.4 / LIBC v0.6 - Alpha 2:
|
|---|
| 121 | ---------------------------------
|
|---|
| 122 |
|
|---|
| 123 | This release have been timebombed and will stop work at the
|
|---|
| 124 | end of October 2004. The reason for this is that data structures
|
|---|
| 125 | shared between LIBC 0.6 and all future LIBC versions are not yet
|
|---|
| 126 | finalized.
|
|---|
| 127 |
|
|---|
| 128 |
|
|---|
| 129 | New Features:
|
|---|
| 130 |
|
|---|
| 131 | o Updated GCC to version 3.3.4.
|
|---|
| 132 |
|
|---|
| 133 | o 2nd fork() implementation.
|
|---|
| 134 | All binaries are by default forkable, use the link option
|
|---|
| 135 | -Zno-fork to disable this.
|
|---|
| 136 | The fork implementation rendered _rmutex useless and it
|
|---|
| 137 | has been removed.
|
|---|
| 138 |
|
|---|
| 139 | o Symlinks using EAs. This is work in progress. One of the
|
|---|
| 140 | limitiations is that readir will not report DT_LNK yet.
|
|---|
| 141 |
|
|---|
| 142 | o Unix compartment using chroot(). This offers a
|
|---|
| 143 | redirection of '/' to the chroot'ed root. The entrance
|
|---|
| 144 | to the compartment is the '/'. The exits are drive letters.
|
|---|
| 145 | The unix compartment is inherited by LIBC child processes.
|
|---|
| 146 |
|
|---|
| 147 | o getcwd() will now return the driveletter too (as VAC does)
|
|---|
| 148 | when not inside the unix compartement.
|
|---|
| 149 | _getcwdux() has been provided for porters which requires
|
|---|
| 150 | behaviour like the old getcwd() implementation.
|
|---|
| 151 |
|
|---|
| 152 | o Paths to unix files #defined in headers are now prefixed
|
|---|
| 153 | with "/@unixroot" which will be redirected to where the
|
|---|
| 154 | environment variable UNIXROOT points. After calling
|
|---|
| 155 | chroot() the target of "/@unixroot" will be changed too.
|
|---|
| 156 |
|
|---|
| 157 | o LIBC specific path rewriting (redirection). Built in is
|
|---|
| 158 | "/dev/null", "/dev/tty" and "/@unixroot".
|
|---|
| 159 | The environment variable LIBC_PATHREWRITERS is examined
|
|---|
| 160 | during init and DLLs specified in it are loaded and called.
|
|---|
| 161 | See src/emx/src/sys/pathrewrite.c for more details.
|
|---|
| 162 |
|
|---|
| 163 | o Non-unix like mode - link option -Zno-unix.
|
|---|
| 164 | This affects slashes and various other Unix-like features
|
|---|
| 165 | like for instance fork and symlinks.
|
|---|
| 166 |
|
|---|
| 167 | o Printf et al. have been extended to support some new format
|
|---|
| 168 | specifiers. (It's still lacking a bit to be SuS comforming.)
|
|---|
| 169 |
|
|---|
| 170 | o Sockets handles are now inherited by LIBC child processes.
|
|---|
| 171 |
|
|---|
| 172 | o LIBC specific filehandle flags are now inherited by LIBC
|
|---|
| 173 | child processes.
|
|---|
| 174 |
|
|---|
| 175 | o The GCCxyz.DLL is no longer needed when LIBC is used.
|
|---|
| 176 | However it is still shipped for special cases where LIBC
|
|---|
| 177 | isn't needed.
|
|---|
| 178 |
|
|---|
| 179 | o A good bunch of 'new' functions both from the SuS and from
|
|---|
| 180 | various Unix flavors, even one or two PC functions have been
|
|---|
| 181 | added. Accompanying these are new headers and header updates.
|
|---|
| 182 | Here are most of the new function names:
|
|---|
| 183 | __strverscmp(), _atfork_callback(), _getcwdux(),
|
|---|
| 184 | _getdcwd(), _nsdbtaddsrc(), _nsdbtput(), _nsdispatch(),
|
|---|
| 185 | _realrealpath(), canonicalize_file_name(), catclose(),
|
|---|
| 186 | catgets(), catopen(), chown(), chroot(), eaccess(),
|
|---|
| 187 | endgrent(), endnetgrent(), endusershell(), fchown(),
|
|---|
| 188 | fstatfs(), fstatvfs(), getdtablesize(), getfsstat(),
|
|---|
| 189 | getgrent(), getgrent_r(), getgrgid_r(), getgrnam_r(),
|
|---|
| 190 | getloadavg(), getmntinfo(), getnetgrent(),
|
|---|
| 191 | getpwent_r(), getpwnam_r(), getpwuid_r(), getrlimit(),
|
|---|
| 192 | getusershell(), innetgr(), lchown(), link(), mknod(),
|
|---|
| 193 | readlink(), setgrent(), setgroupent(), setgroups(),
|
|---|
| 194 | setnetgrent(), setpassent(), setrlimit(),
|
|---|
| 195 | setusershell(), sl_add(), sl_find(), sl_free(),
|
|---|
| 196 | sl_init(), statfs(), statvfs(), strmode(), strtok_r(),
|
|---|
| 197 | symlink() and sync().
|
|---|
| 198 |
|
|---|
| 199 |
|
|---|
| 200 | Bug fixes:
|
|---|
| 201 |
|
|---|
| 202 | o setlocale() have been rewritten. The code page is now
|
|---|
| 203 | taken from the locale rather than OS/2. Old behaviour
|
|---|
| 204 | is used if environment variable LIBC_SETLOCALE_OLDSTYLE
|
|---|
| 205 | is defined.
|
|---|
| 206 |
|
|---|
| 207 | o Buggy strspn() replaced by BSD implementation.
|
|---|
| 208 |
|
|---|
| 209 | o Thread backend have been reworked fixing certain
|
|---|
| 210 | problems when LIBC was loaded and initialized in threads
|
|---|
| 211 | other than the primary one. A LIBC specific TLS api
|
|---|
| 212 | was created during this effort.
|
|---|
| 213 |
|
|---|
| 214 | o Fixed a missing export from GCCxyz.dll which was causing
|
|---|
| 215 | incorrect behaviour of C++ exceptions in all previous
|
|---|
| 216 | releases.
|
|---|
| 217 |
|
|---|
| 218 | o Fixed a buffer overrun in iconv_open() which caused a
|
|---|
| 219 | corruption of the FS selector register, thus crashing
|
|---|
| 220 | the processing.
|
|---|
| 221 |
|
|---|
| 222 | o ...
|
|---|
| 223 |
|
|---|
| 224 |
|
|---|
| 225 | Known limitations and bugs:
|
|---|
| 226 |
|
|---|
| 227 | o mktime() works incorrectly for exterme values causing
|
|---|
| 228 | configure test to fail.
|
|---|
| 229 |
|
|---|
| 230 | o NSS probably doesn't work.
|
|---|
| 231 |
|
|---|
| 232 | o Trailing slashes of a path specification are not
|
|---|
| 233 | handled correctly after the rewrite of the path
|
|---|
| 234 | handling.
|
|---|
| 235 |
|
|---|
| 236 | o New path handling is not DBCS ready.
|
|---|
| 237 |
|
|---|
| 238 | o Socket handle duplication have not been implemented yet.
|
|---|
| 239 |
|
|---|
| 240 | o The __<syscall> function are in the process of being
|
|---|
| 241 | removed.
|
|---|
| 242 |
|
|---|
| 243 | o Not tested with mozilla.
|
|---|
| 244 |
|
|---|
| 245 |
|
|---|
| 246 |
|
|---|
| 247 | v3.2.2 Beta 4 CSD 1:
|
|---|
| 248 | --------------------
|
|---|
| 249 |
|
|---|
| 250 | Bug fixes:
|
|---|
| 251 |
|
|---|
| 252 | o Fixed crash in file stream allocation code.
|
|---|
| 253 |
|
|---|
| 254 | o Fixed incorrect time on machines which had DATETIME::timezone
|
|---|
| 255 | set. This fix changes the time granularity from hundredths of
|
|---|
| 256 | a second to milliseconds.
|
|---|
| 257 |
|
|---|
| 258 | o Added the SPBCDATA struct, the defines FCF_CLOSEBUTTON and
|
|---|
| 259 | BS_NOTEBOOKBUTTON and infosegment structs to os2emx.h
|
|---|
| 260 |
|
|---|
| 261 | o Fixed bug in sys/locale.h where it hid the lconv struct.
|
|---|
| 262 |
|
|---|
| 263 | o Fixed missing error number translations in getsockopt() and
|
|---|
| 264 | setsockopt().
|
|---|
| 265 |
|
|---|
| 266 | o Fixed potential conflict caused by sys/types.h not defining
|
|---|
| 267 | _KEY_T with the key_t typedef.
|
|---|
| 268 |
|
|---|
| 269 | o Fixed missing 64bit I/O support in ftell(), fstat() and stat().
|
|---|
| 270 |
|
|---|
| 271 | o Fixed UCS-2 codepage mappings.
|
|---|
| 272 |
|
|---|
| 273 | o Fixed problem with emxbind not recognizing option -e and
|
|---|
| 274 | a problem with case sensitivity in the export checking.
|
|---|
| 275 |
|
|---|
| 276 |
|
|---|
| 277 | v3.2.2 Beta 4:
|
|---|
| 278 | --------------
|
|---|
| 279 |
|
|---|
| 280 | (The changelog is removed, thus the release notes are more detailed.)
|
|---|
| 281 |
|
|---|
| 282 | New features and fixes:
|
|---|
| 283 |
|
|---|
| 284 | o Filehandle rewrite. Files, pipes and sockets now share the same
|
|---|
| 285 | handle space.
|
|---|
| 286 |
|
|---|
| 287 | o Updated binutils from v2.11.2 to v2.14 adding as-elf.exe and
|
|---|
| 288 | ld-elf.exe as goodies for the adventurous.
|
|---|
| 289 |
|
|---|
| 290 | o GCC defines __INNOTEK_LIBC__=0x005.
|
|---|
| 291 | The value reflects the LIBC version, form: 0xGMM
|
|---|
| 292 | Where G=major version and MM=middle version numbers.
|
|---|
| 293 |
|
|---|
| 294 | o Changed library search algorithms for the linkers (emxomfld
|
|---|
| 295 | and ld). Three variations, static, shared and shared+dll.
|
|---|
| 296 | (The options indicated corresponds to what binutils 2.12.x
|
|---|
| 297 | documents.)
|
|---|
| 298 | static: (-Bstatic, -non_shared, -dn, -static)
|
|---|

| 309 | 6. foo_s.a
|
|---|
| 310 | shared+dll: (-Zdll-search with -Bshared, -call_shared, -dy)
|
|---|
| 311 | 1. libfoo_dll.a
|
|---|
| 312 | 2. foo_dll.a
|
|---|
| 313 | 3. libfoo.a

| 316 | 6. libfoo_s.a
|
|---|
| 317 | 7. foo_s.a
|
|---|
| 318 |
|
|---|
| 319 | o Added some deadlock checking/termination checks to semphores.
|
|---|
| 320 |
|
|---|
| 321 | o Added macros to os2emx.h for preserving FPU control word and
|
|---|
| 322 | applied these to certain read and write operations in LIBC.
|
|---|
| 323 |
|
|---|
| 324 | o Added feature to emxomfld to automatically convert a.out
|
|---|
| 325 | libraries and objects to OMF (using temporary files). Enabled
|
|---|
| 326 | by default but can be disabled by the option -Zno-autoconv.
|
|---|
| 327 |
|
|---|
| 328 | o Added support to emximp for dlls.
|
|---|
| 329 |
|
|---|
| 330 | o Added support for automatic conversion of dlls to temporary
|
|---|
| 331 | import libraries emxomfld and ld.
|
|---|
| 332 |
|
|---|
| 333 | o Added getopt_long() and changed getopt() to FreeBSD
|
|---|
| 334 | implementations.
|
|---|
| 335 |
|
|---|
| 336 | o Added a few more code page aliases.
|
|---|
| 337 |
|
|---|
| 338 | o Added optional breakpoint in abort. The presense of the env.var.
|
|---|
| 339 | LIBC_BREAKPOINT_ABORT triggers the breakpoint instruction.
|
|---|
| 340 |
|
|---|
| 341 | o Added syslog interfaces (contrib from Yuri Dario).
|
|---|
| 342 |
|
|---|
| 343 | o Added to libc and updated BSD db code to FreeBSD 5.1 level.
|
|---|
| 344 |
|
|---|
| 345 | o Added to libc and updated regex code to FreeBSD 5.1 level.
|
|---|
| 346 |
|
|---|
| 347 | o Ported the posix spawn api from GLIBC v2.3.2.
|
|---|
| 348 |
|
|---|
| 349 | o Updated with os2emx.h flags for DosQueryMemState().
|
|---|
| 350 |
|
|---|
| 351 | o Changed size_t to unsigned int (from unsigned long int) and
|
|---|
| 352 | ptrdiff_t to signed int (from signed long int) to comply with
|
|---|
| 353 | most of the other i386 environments.
|
|---|
| 354 |
|
|---|
| 355 | o Changed abort and default signal termination messages to say
|
|---|
| 356 | which process it's printed from.
|
|---|
| 357 |
|
|---|
| 358 | o Changed the glob() and globfree() implemenation with a port of

|
|---|
| 361 | o Changed so_ioctl() to os2_ioctl() to better match the toolkit.
|
|---|
| 362 |
|
|---|
| 363 | o Changed time_t to be signed as in BSD & linux.
|
|---|
| 364 | (Negative values means date/time before epoc.)
|
|---|
| 365 |
|
|---|
| 366 | o Changed to FreeBSD implementation of difftime().
|
|---|
| 367 |
|
|---|
| 368 | o Increased default stream buffer size to 2 pages.
|
|---|
| 369 |

|
|---|
| 380 |
|
|---|
| 381 | o Fixed broken setenv().
|
|---|
| 382 |
|
|---|
| 383 | o Fixed errno value for read() and write() when the handle isn't
|
|---|
| 384 | opened for that operation.
|
|---|
| 385 |
|
|---|

| 391 |
|
|---|
| 392 | o Fixed weakld problem with selfrefering aliases.
|
|---|
| 393 |
|

|
|---|
| 401 |
|
|---|
| 402 | o Fixed crash in ld when having fixups to weak symbols.
|
|---|
| 403 |
|
|---|
| 404 | o Fixed bad conversion of dll0*.o to OMF, the OMF version got an
|
|---|
| 405 | unwanted stack object.
|
|---|
| 406 |
|
|---|
| 407 | o New functions:
|
|---|
| 408 | isblank(), ishexnumber(), isnumber(), mempcpy(), realpath(),
|
|---|
| 409 | strnlen(), asctime_r(), ctime_r(), gmtime_r(), localtime_r(),
|
|---|
| 410 | strerror_r(), usleep().
|
|---|
| 411 |
|
|---|
| 412 | o New functions & globals (from FreeBSD 5.1):

|
|---|
| 416 | strsignal(), sys_signame, sys_siglist, sys_nsig, regcomp(),
|
|---|
| 417 | regerror(), regexec(), regfree(), + bsd db functions.
|
|---|
| 418 |
|
|---|
| 419 | o New functions (from GLIBC 2.3.2):
|
|---|
| 420 | error(), error_at_line(), strndup(), argz_add(),
|
|---|
| 421 | argz_add_sep(), argz_append(), argz_count(), argz_create(),
|
|---|
| 422 | argz_create_sep(), argz_delete(), argz_extract(),
|
|---|
| 423 | argz_insert(), argz_next(), argz_replace(), argz_stringify(),
|
|---|
| 424 | posix_spawnp() posix_spawn(), posix_spawnattr_destroy(),
|
|---|
| 425 | posix_spawnattr_getflags(), posix_spawnattr_getpgroup(),
|
|---|

|---|
| 430 | posix_spawnattr_setflags(), posix_spawnattr_setpgroup(),
|
|---|
| 431 | posix_spawnattr_setschedparam(),

|
|---|
| 439 | posix_spawn_file_actions_init()
|
|---|
| 440 |
|
|---|
| 441 | o New headers:
|
|---|
| 442 | nerrno.h (toolkit compatability).
|
|---|
| 443 |
|
|---|
| 444 | o New headers (from FreeBSD 5.1):
|
|---|
| 445 | search.h, sys/queue.h, net/if_types.h.
|
|---|
| 446 |
|
|---|
| 447 | o New headers (from GLIBC 2.3.2):
|
|---|
| 448 | features.h (somewhat crippled),
|
|---|
| 449 | sys/gnu/cdefs.h (included from BSD styled sys/cdefs.h).
|
|---|
| 450 |
|
|---|
| 451 | o Updated headers:
|
|---|
| 452 | stddef.h (FreeBSD, sys/stddef.h (FreeBSD),
|
|---|
| 453 | ulsitem.h (missing defines), os2emx.h, ...
|
|---|
| 454 |
|
|---|
| 455 | o What I forgot...

|
|---|
| 458 | v3.2.2 Beta 3 Fix 1 (private build):
|
|---|
| 459 | ------------------------------------
|
|---|
| 460 |
|
|---|
| 461 | Fixes to LIBC:
|
|---|
| 462 |
|
|---|
| 463 | o Crash if calloc was called before main().
|
|---|
| 464 |
|
|---|
| 465 | o TZ parsing of timezones such as PST8EDT.
|
|---|
| 466 |
|
|---|
| 467 | o sigsetjmp() and siglongjmp() visibility.
|
|---|
| 468 |
|
|---|
| 469 |
|
|---|
| 470 | v3.2.2 Beta 3:
|
|---|
| 471 | --------------
|
|---|
| 472 |
|
|---|
| 473 | A few new features and fixes.
|
|---|
| 474 |
|
|---|
| 475 | o Fixed a bunch of debug info problems.
|
|---|
| 476 |
|
|---|
| 477 | o Added large file support.
|
|---|
| 478 |
|
|---|
| 479 | o Enabled high memory support for LIBC. Two new options to GCC:
|
|---|
| 480 | -Zhigh-mem and -Zhigh-low. If the program is to be enabled for
|
|---|
| 481 | high memory use, specify -Zhigh-mem when linking.
|
|---|
| 482 |
|
|---|
| 483 | Note that socket is not high memory enabled yet.
|
|---|
| 484 |
|
|---|
| 485 | o Made LIBC preserve the FS selector.
|
|---|
| 486 |
|
|---|
| 487 | o Added random() and *rand48() from BSD.
|
|---|
| 488 |
|
|---|
| 489 | o Fixed crash with link386 and unresolved symbols.
|
|---|
| 490 |
|
|---|
| 491 |
|
|---|
| 492 | v3.2.2 Beta 2:
|
|---|
| 493 | --------------
|
|---|
| 494 |
|
|---|
| 495 | A few bugfixes and a some new features (as usual).
|
|---|
| 496 |
|
|---|
| 497 | o Added file locking support to LIBC.
|
|---|
| 498 |
|
|---|
| 499 | o Fixed _System and _Optlink bugs and made _Optlink support
|
|---|
| 500 | floating point argument passing in registers.
|
|---|
| 501 |
|
|---|
| 502 | o Header updates related to limits and file locking primarily.
|
|---|
| 503 |
|
|---|
| 504 | o Timezone fixes.
|
|---|
| 505 |
|
|---|
| 506 | o Fixed some CRT init trouble in regards to getenv and putenv.
|
|---|
| 507 |
|
|---|
| 508 | o And some other minor stuff..
|
|---|
| 509 |
|
|---|
| 510 |
|
|---|
| 511 | v3.2.2 Beta 1:
|
|---|
| 512 | --------------
|
|---|
| 513 |
|
|---|
| 514 | A few bugfixes and a some new features.
|
|---|
| 515 |
|
|---|
| 516 | o Locale support in libc.
|
|---|
| 517 |
|
|---|
| 518 | o Implemented a different approach to OMF and weak symbols. This
|
|---|
| 519 | new hack performs pre-linking before invoking the OMF linker
|
|---|
| 520 | generating new .def files if needed and an extra object file with
|
|---|
| 521 | aliases to resolve the weak symbols correctly.
|
|---|
| 522 | The old approach will be used used when GCC_WEAKSYMS is present in
|
|---|
| 523 | the environment.
|
|---|
| 524 |
|
|---|
| 525 | Please note that due to a bug in BFD, weak symbols don't work
|
|---|
| 526 | 100% correctly. This will be addressed as soon as we have
|
|---|
| 527 | performed the switch to a more recent version of binutils.
|
|---|
| 528 |
|
|---|
| 529 | o A couple of new functions in libc, and a few corrections to
|
|---|
| 530 | existing in respect to namespaces.
|
|---|
| 531 |
|
|---|
| 532 | o Addressed issues with calling conventions. We now detect
|
|---|
| 533 | incompatible calling conventions, emitting warnings and errors
|
|---|
| 534 | where appropriate.
|
|---|
| 535 |
|
|---|
| 536 | o _Optlink is much better, but there are still some issues
|
|---|
| 537 | left. Passing prototyped floating point parameters to
|
|---|
| 538 | _Optlink doesn't work. Mixing of parameters which go into
|
|---|
| 539 | registers (eax, edx, ecx) and parameters which
|
|---|
| 540 | don't - void foo(int eax, struct sss s, int edx) - doesn't
|
|---|
| 541 | work. All these issues are being addressed and are expected
|
|---|
| 542 | to be fixed in the next build.
|
|---|
| 543 |
|
|---|
| 544 | o Changed GCC to link with shared libc by default. This means
|
|---|
| 545 | that in order to link with the static libc one has to specify
|
|---|
| 546 | -static. It also means that -Zmtd or -Zcrtdll are no longer
|
|---|
| 547 | required for linking with shared libc and can be removed from
|
|---|
| 548 | all makescripts.
|
|---|
| 549 |
|
|---|
| 550 | o Changed EMXOMFLD defaults to ilink from Visual Age for C++
|
|---|
| 551 | v3.6.5 or later (preferably later). The emxomfld usage output
|
|---|
| 552 | will instruct you on how to use older linkers. For VAC308 and
|
|---|
| 553 | VAC365 linkers /dbgpack is specified if debuginfo is to be
|
|---|
| 554 | generated. Emxomf checks for EMXOMFLD_TYPE=link386 when choosing
|
|---|
| 555 | debug info level.
|
|---|
| 556 |
|
|---|
| 557 | o Shipping three extra libc dlls:
|
|---|
| 558 | libc02.dbg: Unstripped version of libc02.dll. This is
|
|---|
| 559 | identical except from the presense of debug
|
|---|
| 560 | info.
|
|---|
| 561 | libc02.prf: Linked together from profiled enabled
|
|---|
| 562 | libraries using kProfiler.
|
|---|
| 563 | libc02.elh: Standard libc but linked with an external
|
|---|
| 564 | electrical fence heap from kLibDbg.
|
|---|
| 565 | These libc02.* dlls can be used instead of libc02.dll. kLibDbg
|
|---|
| 566 | and kProfiler is available in separate zip files at same
|
|---|
| 567 | location as the rest of the InnoTek GCC suite. However these
|
|---|
| 568 | external tools are provided as is. (I might actually not find
|
|---|
| 569 | time to put them out yet.)
|
|---|
| 570 |
|
|---|
| 571 | o Distribution is splitted into several zips:
|
|---|
| 572 | -core.zip: All you really need.
|
|---|
| 573 | -dbg.zip: Map files, unstripped tools and libs, and
|
|---|
| 574 | libc02.elh.
|
|---|
| 575 | -prf.zip: Profiling libraries and libc02.prf.
|
|---|
| 576 | libc.zip: The runtime libraries. (included in core.)
|
|---|
| 577 | The big zip is everything.
|
|---|
| 578 |
|
|---|
| 579 | v3.2.2 Alpha 3:
|
|---|
| 580 | ---------------
|
|---|
| 581 |
|
|---|
| 582 | Primarily bugfixes.
|
|---|
| 583 |
|
|---|
| 584 | o Changed code generator for floating point truncations (double
|
|---|
| 585 | to int casts and such) so PM can freely mess up the fpu status.
|
|---|
| 586 |
|
|---|
| 587 | o We were using the wrong float.h in two sense. We're now using
|
|---|
| 588 | the correct one which includes all the PC defines and
|
|---|
| 589 | prototypes.
|
|---|
| 590 |
|
|---|
| 591 | o Fixed a few issues with error defines and tcpip.
|
|---|
| 592 | Note that some of the error defines have changed value in the
|
|---|
| 593 | process so we could become compatible with the tcpip stack
|
|---|
| 594 | and FreeBSD.
|
|---|
| 595 |
|
|---|
| 596 | o Corrected bugs in a number of headers.
|
|---|
| 597 |
|
|---|
| 598 | o Added more OS/2 prototypes and imports. There is still work
|
|---|
| 599 | left on the header part,
|
|---|
| 600 |
|
|---|
| 601 | o Optimized emxomf debug info conversion.
|
|---|
| 602 |
|
|---|
| 603 | o Wrapped bsdselect for BSD 4.4 header mode to implement
|
|---|
| 604 | bsdselect().
|
|---|
| 605 |
|
|---|
| 606 | o .... what did we forget...
|
|---|
| 607 |
|
|---|
| 608 |
|
|---|
| 609 | v3.2.2 Alpha 2:
|
|---|
| 610 | ---------------
|
|---|
| 611 |
|
|---|
| 612 | A few bugfixes and a couple of new features.
|
|---|
| 613 |
|
|---|
| 614 | o The TCP/IP headers and libraries scheme have been changed.
|
|---|
| 615 | The default is the current OS/2 tcpip toolkit (BSD 4.4 based).
|
|---|
| 616 | To target the older OS/2 tcpip stack (BSD 4.3 based) you must
|
|---|
| 617 | define TCPV40HDRS before including any TCP/IP headers and make
|
|---|
| 618 | sure usr/lib/tcpipv4 is searched before usr/lib (this is to
|
|---|
| 619 | get the right libsocket). It is recommended to use the -D
|
|---|
| 620 | compiler option for the define and either the LIBRARY_PATH or
|
|---|
| 621 | the -L compiler/linker option for the library.
|
|---|
| 622 |
|
|---|
| 623 | o There are a couple of new and updated based on FreeBSD 5.1.
|
|---|
| 624 | sys\stdint.h and inttypes.h (and a few internal once) are new.
|
|---|
| 625 | sys\types.h and unistd.h are the ones most heavily updated.
|
|---|
| 626 | We're working on getting the headers and libc in a better
|
|---|
| 627 | shape standardwise to easy compatability and portability.
|
|---|
| 628 |
|
|---|
| 629 | o A infinite loop in emxomf has been fixed.
|
|---|
| 630 |
|
|---|
| 631 | o Linker error on sopen() has been corrected.
|
|---|
| 632 |
|
|---|
| 633 | o .... what did we forget...
|
|---|
| 634 |
|
|---|
| 635 |
|
|---|
| 636 | v3.2.2 Alpha 1:
|
|---|
| 637 | ---------------
|
|---|
| 638 |
|
|---|
| 639 | This is the first release from InnoTek, and it contains the InnoTek LIBC.
|
|---|
| 640 | In addition to the new LIBC there is a number of other major changes:
|
|---|
| 641 |
|
|---|
| 642 | o Name mangling in OMF mode have changed.
|
|---|
| 643 | Until this release emxomf used to pretty much strip one leading '_'
|
|---|
| 644 | from symbols when converting them to omf. This is now longer done
|
|---|
| 645 | chiefly in order to correctly support mangling calling conventions
|
|---|
| 646 | like __stdcall and __cdecl. This change have the following side
|
|---|
| 647 | effects:
|
|---|
| 648 | - _System and __cdecl no longer produces the same names and hence
|
|---|
| 649 | all OS/2 API which are _System must be declared as _System in
|
|---|
| 650 | order to link.
|
|---|
| 651 | - Assembly code might need an extra underscore to work, or
|
|---|
| 652 | perhaps change the prototypes to _System.
|
|---|
| 653 | - Global variables are prepended and underscore, so mixing VAC and
|
|---|
| 654 | GCC, or accessing globals from asm, take care.
|
|---|
| 655 | (MSC v6.0 does this too, so it's not any uncommon practise.)
|
|---|
| 656 |
|
|---|
| 657 | The OS/2 headers which are included are all updated to use _System.
|
|---|
| 658 |
|
|---|
| 659 | o TCPIP headers are updated a quite a bit to match the toolkit ones
|
|---|
| 660 | and to reflect the fact that the new libc does not a having common
|
|---|
| 661 | handle space for files and sockets. These changes aren't 100%
|
|---|
| 662 | completed yet, and usage probably will uncover some issues left in
|
|---|
| 663 | there. Also for the programmer there is the following changes in
|
|---|
| 664 | the apis provided:
|
|---|
| 665 | - TCPV40HDRS are supported and should work like with the toolkit
|
|---|
| 666 | headers. It will alias all functions to tcpip40_ editions
|
|---|
| 667 | (using #defines) so we get the right imports thru -llibsocket.
|
|---|
| 668 | - There is no support for sockets in select(). To do select on
|
|---|
| 669 | sockets you will have to use bsdselect() or os2_select().
|
|---|
| 670 | bsdselect() is only available for TCPV40HDRS. For
|
|---|
| 671 | !defined(TCPV40HDRS) fd_set is in the emx/bsd format and not the
|
|---|
| 672 | OS/2 tcpip v5.0 format.
|
|---|
| 673 | - Socket IOCTLs are not supported by the ioctl() libc function
|
|---|
| 674 | because of the separate handle space for sockets. For sockets
|
|---|
| 675 | so_ioctl() and os2_ioctl() are used. os2_ioctl() is not available
|
|---|
| 676 | when TCPV40HDRS is defined. According to the tcpref in v5.0
|
|---|
| 677 | so_ioctl() only supports BSD ioctls.
|
|---|
| 678 | - writev() and readv() also clashes with libc. For socket handles
|
|---|
| 679 | use so_writev() and so_readv().
|
|---|
| 680 |
|
|---|
| 681 | o The prefered OMF linker is now ilink. link386 will fail with an odd
|
|---|
| 682 | error message if you tell gcc/g++ to make debug info. Set the
|
|---|
| 683 | EMXOMFLD_LINKER environment variable to value ilink in order to use
|
|---|
| 684 | ilink as OMF linker.
|
|---|
| 685 | It likely that we will change the default OMF linker to ilink in an
|
|---|
| 686 | later version of the GCC suite.
|
|---|
| 687 |
|
|---|
| 688 | o .... what did we forget...
|
