| 106 | GCC v3.3.5 / LIBC v0.6 - Beta 5:
|
|---|
| 107 | --------------------------------
|
|---|
| 108 |
|
|---|
| 109 | Thanks to Lorne, Froloff, nickk and Andy for sending me patches,
|
|---|
| 110 | debugging problems and/or testing fixes.
|
|---|
| 111 |
|
|---|
| 112 | New features:
|
|---|
| 113 |
|
|---|
| 114 | o Added support for __declspec(dllexport), _Export
|
|---|
| 115 | and __declspec(dllimport), the latter being a stub.
|
|---|
| 116 | This also included adding N_EXP to the a.out format.
|
|---|
| 117 |
|
|---|
| 118 | o Lot's of math stuff, mostly untested.
|
|---|
| 119 |
|
|---|
| 120 | o Optimized zeroing of new file space in ftruncate and
|
|---|
| 121 | chsize with knowlegde about the filesystem. HPFS, JFS
|
|---|
| 122 | and FAT will do the zeroing for us.
|
|---|
| 123 |
|
|---|
| 124 | o Support for unlocked stdio, with both BSD and GNU
|
|---|
| 125 | extensions implemented.

|---|
| 135 |
|
|---|
| 136 | o Ported the FreeBSD implementation of SysV semaphores
|
|---|
| 137 | and shared memory.
|
|---|
| 138 |
|
|---|
| 139 | o Env.var. LIBC_THREAD_MIN_STACK_SIZE can be used to
|
|---|
| 140 | specify the minimum stack size for new threads. The
|
|---|
| 141 | default minimum is 4096 bytes.
|
|---|
| 142 |
|
|---|
| 143 | o Ported (lib)intl from glibc.

|---|
| 292 | o Corrected NP_NBLK define in os2emx.h.
|
|---|

| 305 |
|
|---|
| 306 | Todos before LIBC06.DLL:
|
|---|
| 307 |
|
|---|
| 308 | 0. Fix all bugs. :-)
|
|---|
| 309 |
|
|---|
| 310 | 1. Reimplement opendir in BSD style (+fchdir).
|
|---|
| 311 |
|
|---|
| 312 | 2. Shared IPC structures for XSI msq, sem and shm.
|
|---|
| 313 |
|
|---|
| 314 | 3. Missing job pgid functions.
|
|---|
| 315 |
|
|---|
| 316 | 4. Port GLIBC intl/*. gettext is a pita! because it's
|
|---|
| 317 | passing FILE pointers around between different LIBCs.
|
|---|
| 318 | objdump is constantly broken between LIBC versions.
|
|---|
| 319 |
|
|---|
| 320 | 5. Figure out the EA exclusive read access trouble.
|
|---|
| 321 |

|
|---|
| 335 |
|
|---|
| 336 | o wchar.h and wctype.h and much of the non-stream functions
|
|---|
| 337 | declared therein are implemented. Though, the FreeBSD
|
|---|
| 338 | string/w*.c functions are still in the porting queue.
|
|---|
| 339 |
|
|---|
| 340 | o Added __mcount stub to all LIBC DLLs but the .prf one which
|
|---|
| 341 | is forwarding __mcount from kProfile.dll.
|
|---|
| 342 |
|
|---|
| 343 | o DosLoadModuleEx and DosFreeModuleEx was created to support
|
|---|
| 344 | loaded modules over a fork(). dlopen/dlclose backend was
|
|---|
| 345 | changed to use these.
|
|---|
| 346 |
|
|---|
| 347 | o Fixed rand() range problem. Using the BSD code for this
|
|---|
| 348 | too, which means a new algorithm.
|
|---|
| 349 |
|
|---|
| 350 | o Update all BSD source-files (not headers) to FreeBSD 5.3
|
|---|
| 351 | level.
|
|---|
| 352 |
|
|---|
| 353 | o New functions:
|
|---|
| 354 | DosLoadModuleEx(), DosFreeModuleEx(), sranddev(),
|
|---|
| 355 | getsubopt(), rand_r(), llabs(), lldiv(), dlfunc(),
|
|---|
| 356 | issetugid(), pread(), pwrite(), _UTF8_mbrtowc(),
|
|---|
| 357 | _UTF8_mbsinit(), _UTF8_mbsnrtowcs(), _UTF8_wcrtomb(),
|
|---|
| 358 | _UTF8_wcsnrtombs(), digittoint(), isideogram(),
|
|---|
| 359 | isrune(), iswalnum(), iswalpha(), iswascii(),
|
|---|
| 360 |
|
|---|
| 361 | iswblank(), iswcntrl(), iswctype(), iswdigit(),
|
|---|
| 362 | iswgraph(), iswhexnumber(), iswideogram(), iswlower(),
|
|---|
| 363 | iswnumber(), iswprint(), iswpunct(), iswrune(),
|
|---|
| 364 | iswspace(), iswupper(), iswxdigit(), btowc(), mbrlen(),
|
|---|
| 365 | mbrtowc(), mbsinit(), mbsnrtowcs(), mbsrtowcs(),
|
|---|
| 366 | nl_langinfo(), towctrans(), wcrtomb(), wcsftime(),
|
|---|
| 367 | wcsnrtombs(), wcsrtombs(), wcstod(), wcstof(),
|
|---|
| 368 | wcstoimax(), wcstol(), wcstold(), wcstoll(), wcstoul(),
|
|---|
| 369 | wcstoull(), wcstoumax(), wctob(), wctrans(), wctype(),
|
|---|
| 370 | towlower(), towupper().
|
|---|
| 371 |
|
|---|
| 372 |
|
|---|
| 373 | Bug fixes:
|
|---|
| 374 |
|
|---|
| 375 | o Fixed missing WNOHANG handling in waitpid(), wait4()
|
|---|
| 376 | and waitid().
|
|---|
| 377 |
|
|---|
| 378 | o Corrected several severe bugs in the path resolver.
|
|---|
| 379 |
|
|---|
| 380 | o Fixed handling of paths ending with slash.
|
|---|
| 381 |
|
|---|
| 382 | o Fixed weird fork() problem which showed up as a heap
|
|---|
| 383 | deadlock.
|
|---|
| 384 |
|
|---|
| 385 | o Fixed broken _getdrive().
|
|---|
| 386 |
|
|---|
| 387 | o Made _chdrive() return -1 on error. It used to always
|
|---|
| 388 | return success earlier. (don't ask me why)
|
|---|
| 389 |
|
|---|
| 390 | o Fixed incorrect handling of -shared in GCC. It should
|
|---|
| 391 | be treated as -Zdll.
|
|---|
| 392 |
|
|---|
| 393 | o Various incorrect assertions in the strict/log build.
|
|---|
| 394 |
|
|---|
| 395 | o ...
|
|---|
| 396 |
|
|---|
| 397 | Known Limitiations/Problems:
|
|---|
| 398 |
|
|---|
| 399 | o Static linking not possible - might be fixed later.
|
|---|
| 400 |
|
|---|
| 401 | o Job control will only be applied to thread 1 in a process.
|
|---|
| 402 | This won't change.
|
|---|
| 403 |
|
|---|
| 404 | o Missing some process group interfaces required for
|
|---|
| 405 | job control. They'll show up soon I hope.
|
|---|
| 406 |
|
|---|
| 407 | o Not tested too well. Especially the regex update.
|
|---|
| 408 |
|
|---|
| 409 | Todos before LIBC06.DLL:
|
|---|
| 410 |
|
|---|
| 411 | 0. Fix all bugs. :-)
|
|---|
| 412 |
|
|---|
| 413 | 1. Implement new ino_t scheme and reimplement opendir
|
|---|
| 414 | in BSD style while doing so (+fchdir).
|
|---|
| 415 |
|
|---|
| 416 | 2. Shared IPC structures for XSI msq, sem and shm.
|
|---|
| 417 |
|
|---|
| 418 | 3. Port string/w* functions.
|
|---|
| 419 |
|
|---|
| 420 | 4. Missing job pgid functions.
|
|---|
| 421 |
|
|---|
| 422 | 5. Port GLIBC intl/*. gettext is a pita! because it's
|
|---|
| 423 | passing FILE pointers around between different LIBCs.
|
|---|
| 424 | objdump is constantly broken between LIBC versions.
|
|---|
| 425 |
|
|---|
| 426 |
|
|---|
| 427 |
|
|---|
| 428 | GCC v3.3.5 / LIBC v0.6 - Beta 1:
|
|---|
| 429 | --------------------------------
|
|---|
| 430 |
|
|---|
| 431 | New features:
|
|---|
| 432 |
|
|---|
| 433 | o setitimer/alarm implementation. Needs some review later
|
|---|
| 434 | the accuracy isn't extacly great.
|
|---|
| 435 |
|
|---|
| 436 | o Added a couple of missing os2emx.h features.
|
|---|
| 437 |
|
|---|
| 438 | o Some more 16-bit thunkers.
|
|---|
| 439 |
|
|---|
| 440 | Bug fixes:
|
|---|
| 441 |
|
|---|
| 442 | o Select worker called wrong tcpip function.
|
|---|
| 443 |
|
|---|
| 444 | o Incorrect assertion during thread destruction.
|
|---|
| 445 |
|
|---|
| 446 | o Fixed broken chdir and getdrive.
|
|---|
| 447 |
|
|---|
| 448 | o Improved deadlock detection (fmutex have changed,
|
|---|
| 449 | thus stdio FILE is also changed).
|
|---|
| 450 |
|
|---|
| 451 | o ...
|
|---|
| 452 |
|
|---|
| 453 |
|
|---|
| 454 | Known Limitiations/Problems:
|
|---|
| 455 |
|
|---|
| 456 | o Static linking not possible - will be fixed.
|
|---|
| 457 |
|
|---|
| 458 | o Job control will only be applied to thread 1 in a process.
|
|---|
| 459 | This won't change.
|
|---|
| 460 |
|
|---|
| 461 | o Missing some process group interfaces required for
|
|---|
| 462 | job control. They'll show up soon.
|
|---|
| 463 |
|
|---|
| 464 | o Doesn't evaluate trailing slash in paths as directory
|
|---|
| 465 | specifier, it's currently ignored.
|
|---|
| 466 |
|
|---|
| 467 |
|
|---|
| 468 |
|
|---|
| 469 | GCC v3.3.5 / LIBC v0.6 - Alpha 3:
|
|---|
| 470 | ---------------------------------
|
|---|
| 471 |
|
|---|
| 472 | This release have been timebombed and will stop working at the
|
|---|
| 473 | end of December 2004. The reason for this is that data structures
|
|---|
| 474 | shared between LIBC 0.6 and all future LIBC versions are not yet
|
|---|
| 475 | quite finalized. (For your comfort the timebomb will go away when
|
|---|
| 476 | the betas start, and this is the last planned LIBC v0.6 alpha.)
|
|---|
| 477 |
|
|---|
| 478 |
|
|---|
| 479 | New Features:
|
|---|
| 480 |
|
|---|
| 481 | o Updated GCC to version 3.3.5.
|
|---|
| 482 |
|
|---|
| 483 | o Replaced the signal implementation. The new implementation
|
|---|
| 484 | is much closer to the POSIX specs and implements a lot of
|
|---|
| 485 | new interfaces.
|
|---|
| 486 |
|
|---|
| 487 | o Experimental delayed loading import libraries. emximp have
|
|---|
| 488 | a new -l option for generating such libraries. At present
|
|---|
| 489 | emximp can only generate a.out libraries of this kind - so
|
|---|
| 490 | use emxomf to convert to OMF.
|
|---|
| 491 |
|
|---|
| 492 | o The dlfcn.h functions are in LIBC now.
|
|---|
| 493 |
|
|---|
| 494 | o New functions:
|
|---|
| 495 | getgrouplist(), initgroups(), memalign(), valloc(),
|
|---|
| 496 | mprotect(), _signal_os2(), _signal_sysv(),
|
|---|
| 497 | __sigpause_bsd(), bsd_signal(), killpg(), psignal(),
|
|---|
| 498 | sigaltstack(), sigblock(), sighold(), sigignore(),
|
|---|
| 499 | siginterrupt(), sigpause(), sigrelse(), sigsetmask(),
|
|---|
| 500 | sigtimedwait(), sigvec(), sigwait(), sigwaitinfo(),
|
|---|
| 501 | sigqueue(), sigset(), getgrgid(), getpwnam(),
|
|---|
| 502 | getpwuid(), setegid(), seteuid(), setregid(),
|
|---|
| 503 | setresgid(), setresuid(), setreuid(),
|
|---|
| 504 | setrgid(), setruid(), waitid(), wait3(),
|
|---|
| 505 | wait4() and getopt_long_only().
|
|---|
| 506 |
|
|---|
| 507 |
|
|---|
| 508 | Bug fixes;
|
|---|
| 509 |
|
|---|
| 510 | o Sockets were broken on some systems. Hopefully, this
|
|---|
| 511 | should be corrected now.
|
|---|
| 512 |
|
|---|
| 513 | o stat() failed on a file open for writing.
|
|---|
| 514 |
|
|---|
| 515 | o fork() didn't work for processes which allocated lot's
|
|---|
| 516 | of memory. Fixed incorrect syncing of memory objects.
|
|---|
| 517 |
|
|---|
| 518 | o ...
|
|---|
| 519 |
|
|---|
| 520 |
|
|---|
| 521 | Known Limitiations/Problems:
|
|---|
| 522 |
|
|---|
| 523 | o Static linking not possible - will be fixed.
|
|---|
| 524 |
|
|---|
| 525 | o alarm() is still missing. Code is 80% done but didn't
|
|---|
| 526 | make it for the release.
|
|---|
| 527 |
|
|---|
| 528 | o Job control will only be applied to thread 1 in a process.
|
|---|
| 529 | This won't change.
|
|---|
| 530 |
|
|---|
| 531 | o Missing some process group interfaces required for
|
|---|
| 532 | job control. They'll show up soon.
|
|---|
| 533 |
|
|---|
| 534 |
|
|---|
| 535 |
|
|---|
| 536 | GCC v3.3.4 / LIBC v0.6 - Alpha 2:
|
|---|
| 537 | ---------------------------------
|
|---|
| 538 |
|
|---|
| 539 | This release have been timebombed and will stop work at the
|
|---|
| 540 | end of October 2004. The reason for this is that data structures
|
|---|
| 541 | shared between LIBC 0.6 and all future LIBC versions are not yet
|
|---|
| 542 | finalized.
|
|---|
| 543 |
|
|---|
| 544 |
|
|---|
| 545 | New Features:
|
|---|
| 546 |
|
|---|
| 547 | o Updated GCC to version 3.3.4.
|
|---|
| 548 |
|
|---|
| 549 | o 2nd fork() implementation.
|
|---|
| 550 | All binaries are by default forkable, use the link option
|
|---|
| 551 | -Zno-fork to disable this.
|
|---|
| 552 | The fork implementation rendered _rmutex useless and it
|
|---|
| 553 | has been removed.
|
|---|
| 554 |
|
|---|
| 555 | o Symlinks using EAs. This is work in progress. One of the
|
|---|
| 556 | limitiations is that readir will not report DT_LNK yet.
|
|---|
| 557 |
|
|---|
| 558 | o Unix compartment using chroot(). This offers a
|
|---|
| 559 | redirection of '/' to the chroot'ed root. The entrance
|
|---|
| 560 | to the compartment is the '/'. The exits are drive letters.
|
|---|
| 561 | The unix compartment is inherited by LIBC child processes.
|
|---|
| 562 |
|
|---|
| 563 | o getcwd() will now return the driveletter too (as VAC does)
|
|---|
| 564 | when not inside the unix compartement.
|
|---|
| 565 | _getcwdux() has been provided for porters which requires
|
|---|
| 566 | behaviour like the old getcwd() implementation.
|
|---|
| 567 |
|
|---|
| 568 | o Paths to unix files #defined in headers are now prefixed
|
|---|
| 569 | with "/@unixroot" which will be redirected to where the
|
|---|
| 570 | environment variable UNIXROOT points. After calling
|
|---|
| 571 | chroot() the target of "/@unixroot" will be changed too.
|
|---|
| 572 |
|
|---|
| 573 | o LIBC specific path rewriting (redirection). Built in is
|
|---|
| 574 | "/dev/null", "/dev/tty" and "/@unixroot".
|
|---|
| 575 | The environment variable LIBC_PATHREWRITERS is examined
|
|---|
| 576 | during init and DLLs specified in it are loaded and called.
|
|---|
| 577 | See src/emx/src/sys/pathrewrite.c for more details.
|
|---|
| 578 |
|
|---|
| 579 | o Non-unix like mode - link option -Zno-unix.
|
|---|
| 580 | This affects slashes and various other Unix-like features
|
|---|
| 581 | like for instance fork and symlinks.
|
|---|
| 582 |
|
|---|
| 583 | o Printf et al. have been extended to support some new format
|
|---|
| 584 | specifiers. (It's still lacking a bit to be SuS comforming.)
|
|---|
| 585 |
|
|---|
| 586 | o Sockets handles are now inherited by LIBC child processes.
|
|---|
| 587 |
|
|---|
| 588 | o LIBC specific filehandle flags are now inherited by LIBC
|
|---|
| 589 | child processes.
|
|---|
| 590 |
|
|---|
| 591 | o The GCCxyz.DLL is no longer needed when LIBC is used.
|
|---|
| 592 | However it is still shipped for special cases where LIBC
|
|---|
| 593 | isn't needed.
|
|---|
| 594 |
|
|---|
| 595 | o A good bunch of 'new' functions both from the SuS and from
|
|---|
| 596 | various Unix flavors, even one or two PC functions have been
|
|---|
| 597 | added. Accompanying these are new headers and header updates.
|
|---|
| 598 | Here are most of the new function names:
|
|---|
| 599 | __strverscmp(), _atfork_callback(), _getcwdux(),
|
|---|
| 600 | _getdcwd(), _nsdbtaddsrc(), _nsdbtput(), _nsdispatch(),
|
|---|
| 601 | _realrealpath(), canonicalize_file_name(), catclose(),
|
|---|
| 602 | catgets(), catopen(), chown(), chroot(), eaccess(),
|
|---|
| 603 | endgrent(), endnetgrent(), endusershell(), fchown(),
|
|---|
| 604 | fstatfs(), fstatvfs(), getdtablesize(), getfsstat(),
|
|---|
| 605 | getgrent(), getgrent_r(), getgrgid_r(), getgrnam_r(),
|
|---|
| 606 | getloadavg(), getmntinfo(), getnetgrent(),
|
|---|
| 607 | getpwent_r(), getpwnam_r(), getpwuid_r(), getrlimit(),
|
|---|
| 608 | getusershell(), innetgr(), lchown(), link(), mknod(),
|
|---|
| 609 | readlink(), setgrent(), setgroupent(), setgroups(),
|
|---|
| 610 | setnetgrent(), setpassent(), setrlimit(),
|
|---|
| 611 | setusershell(), sl_add(), sl_find(), sl_free(),
|
|---|
| 612 | sl_init(), statfs(), statvfs(), strmode(), strtok_r(),
|
|---|
| 613 | symlink() and sync().
|
|---|
| 614 |
|
|---|
| 615 |
|
|---|
| 616 | Bug fixes:
|
|---|
| 617 |
|
|---|
| 618 | o setlocale() have been rewritten. The code page is now
|
|---|
| 619 | taken from the locale rather than OS/2. Old behaviour
|
|---|
| 620 | is used if environment variable LIBC_SETLOCALE_OLDSTYLE
|
|---|
| 621 | is defined.
|
|---|
| 622 |
|
|---|
| 623 | o Buggy strspn() replaced by BSD implementation.
|
|---|
| 624 |
|
|---|
| 625 | o Thread backend have been reworked fixing certain
|
|---|
| 626 | problems when LIBC was loaded and initialized in threads
|
|---|
| 627 | other than the primary one. A LIBC specific TLS api
|
|---|
| 628 | was created during this effort.
|
|---|
| 629 |
|
|---|
| 630 | o Fixed a missing export from GCCxyz.dll which was causing
|
|---|
| 631 | incorrect behaviour of C++ exceptions in all previous
|
|---|
| 632 | releases.
|
|---|
| 633 |
|
|---|
| 634 | o Fixed a buffer overrun in iconv_open() which caused a
|
|---|
| 635 | corruption of the FS selector register, thus crashing
|
|---|
| 636 | the processing.
|
|---|
| 637 |
|
|---|
| 638 | o ...
|
|---|
| 639 |
|
|---|
| 640 |
|
|---|
| 641 | Known limitations and bugs:
|
|---|
| 642 |
|
|---|
| 643 | o mktime() works incorrectly for exterme values causing
|
|---|
| 644 | configure test to fail.
|
|---|
| 645 |
|
|---|
| 646 | o NSS probably doesn't work.
|
|---|
| 647 |
|
|---|
| 648 | o Trailing slashes of a path specification are not
|
|---|
| 649 | handled correctly after the rewrite of the path
|
|---|
| 650 | handling.
|
|---|
| 651 |
|
|---|
| 652 | o New path handling is not DBCS ready.
|
|---|
| 653 |
|
|---|
| 654 | o Socket handle duplication have not been implemented yet.
|
|---|
| 655 |
|
|---|
| 656 | o The __<syscall> function are in the process of being
|
|---|
| 657 | removed.
|
|---|
| 658 |
|
|---|
| 659 | o Not tested with mozilla.
|
|---|
| 660 |
|
|---|
| 661 |
|
|---|
| 662 |
|
|---|
| 663 | v3.2.2 Beta 4 CSD 1:
|
|---|
| 664 | --------------------
|
|---|
| 665 |
|
|---|
| 666 | Bug fixes:
|
|---|
| 667 |
|
|---|
| 668 | o Fixed crash in file stream allocation code.
|
|---|
| 669 |
|
|---|
| 670 | o Fixed incorrect time on machines which had DATETIME::timezone
|
|---|
| 671 | set. This fix changes the time granularity from hundredths of
|
|---|
| 672 | a second to milliseconds.
|
|---|
| 673 |
|
|---|
| 674 | o Added the SPBCDATA struct, the defines FCF_CLOSEBUTTON and
|
|---|
| 675 | BS_NOTEBOOKBUTTON and infosegment structs to os2emx.h
|
|---|
| 676 |
|
|---|
| 677 | o Fixed bug in sys/locale.h where it hid the lconv struct.
|
|---|
| 678 |
|
|---|
| 679 | o Fixed missing error number translations in getsockopt() and
|
|---|
| 680 | setsockopt().
|
|---|
| 681 |
|
|---|
| 682 | o Fixed potential conflict caused by sys/types.h not defining
|
|---|
| 683 | _KEY_T with the key_t typedef.
|
|---|
| 684 |
|
|---|
| 685 | o Fixed missing 64bit I/O support in ftell(), fstat() and stat().
|
|---|
| 686 |
|
|---|
| 687 | o Fixed UCS-2 codepage mappings.
|
|---|
| 688 |
|
|---|
| 689 | o Fixed problem with emxbind not recognizing option -e and
|
|---|
| 690 | a problem with case sensitivity in the export checking.
|
|---|
| 691 |
|
|---|
| 692 |
|
|---|
| 693 | v3.2.2 Beta 4:
|
|---|
| 694 | --------------
|
|---|
| 695 |
|
|---|
| 696 | (The changelog is removed, thus the release notes are more detailed.)
|
|---|
| 697 |
|
|---|
| 698 | New features and fixes:
|
|---|
| 699 |
|
|---|
| 700 | o Filehandle rewrite. Files, pipes and sockets now share the same
|
|---|
| 701 | handle space.
|
|---|
| 702 |
|
|---|
| 703 | o Updated binutils from v2.11.2 to v2.14 adding as-elf.exe and
|
|---|
| 704 | ld-elf.exe as goodies for the adventurous.
|
|---|
| 705 |
|

|
|---|
| 765 | o Updated with os2emx.h flags for DosQueryMemState().
|
|---|
| 766 |
|
|---|
| 767 | o Changed size_t to unsigned int (from unsigned long int) and
|
|---|
| 768 | ptrdiff_t to signed int (from signed long int) to comply with
|
|---|
| 769 | most of the other i386 environments.

|
|---|
| 800 | opened for that operation.
|
|---|
| 801 |
|
|---|

| 818 | o Fixed crash in ld when having fixups to weak symbols.
|
|---|
| 819 |
|
|---|
| 820 | o Fixed bad conversion of dll0*.o to OMF, the OMF version got an
|
|---|
| 821 | unwanted stack object.
|
|---|
| 822 |
|
|---|
| 823 | o New functions:
|
|---|
| 824 | isblank(), ishexnumber(), isnumber(), mempcpy(), realpath(),
|
|---|
| 825 | strnlen(), asctime_r(), ctime_r(), gmtime_r(), localtime_r(),
|
|---|
| 826 | strerror_r(), usleep().
|
|---|
| 827 |
|

|
|---|
| 833 | regerror(), regexec(), regfree(), + bsd db functions.
|
|---|
| 834 |
|
|---|
| 835 | o New functions (from GLIBC 2.3.2):
|
|---|
| 836 | error(), error_at_line(), strndup(), argz_add(),
|
|---|
| 837 | argz_add_sep(), argz_append(), argz_count(), argz_create(),
|
|---|
| 838 | argz_create_sep(), argz_delete(), argz_extract(),
|
|---|
| 839 | argz_insert(), argz_next(), argz_replace(), argz_stringify(),
|
|---|
| 840 | posix_spawnp() posix_spawn(), posix_spawnattr_destroy(),
|
|---|
| 841 | posix_spawnattr_getflags(), posix_spawnattr_getpgroup(),

|
|---|
| 858 | nerrno.h (toolkit compatability).
|
|---|
| 859 |
|
|---|

|
|---|
| 861 | search.h, sys/queue.h, net/if_types.h.
|
|---|
| 862 |
|
|---|

|
|---|
| 864 | features.h (somewhat crippled),
|
|---|
| 865 | sys/gnu/cdefs.h (included from BSD styled sys/cdefs.h).
|
|---|
| 866 |
|
|---|
| 867 | o Updated headers:
|
|---|
| 868 | stddef.h (FreeBSD, sys/stddef.h (FreeBSD),
|
|---|
| 869 | ulsitem.h (missing defines), os2emx.h, ...
|
|---|
| 870 |

| 871 | o What I forgot...
|
|---|
| 872 |
|
|---|
| 873 |
|
|---|
| 874 | v3.2.2 Beta 3 Fix 1 (private build):
|
|---|
| 875 | ------------------------------------
|
|---|
| 876 |
|
|---|
| 877 | Fixes to LIBC:
|
|---|
| 878 |
|
|---|
| 879 | o Crash if calloc was called before main().
|
|---|
| 880 |
|
|---|
| 881 | o TZ parsing of timezones such as PST8EDT.
|
|---|
| 882 |
|
|---|
| 883 | o sigsetjmp() and siglongjmp() visibility.
|
|---|
| 884 |
|
|---|
| 885 |
|
|---|
| 886 | v3.2.2 Beta 3:
|
|---|
| 887 | --------------
|
|---|
| 888 |
|
|---|
| 889 | A few new features and fixes.
|
|---|
| 890 |
|
|---|
| 891 | o Fixed a bunch of debug info problems.
|
|---|
| 892 |
|
|---|
| 893 | o Added large file support.
|
|---|
| 894 |
|
|---|
| 895 | o Enabled high memory support for LIBC. Two new options to GCC:
|
|---|
| 896 | -Zhigh-mem and -Zhigh-low. If the program is to be enabled for
|
|---|
| 897 | high memory use, specify -Zhigh-mem when linking.
|
|---|
| 898 |
|
|---|
| 899 | Note that socket is not high memory enabled yet.
|
|---|
| 900 |
|
|---|
| 901 | o Made LIBC preserve the FS selector.
|
|---|
| 902 |
|
|---|
| 903 | o Added random() and *rand48() from BSD.
|
|---|
| 904 |
|
|---|
| 905 | o Fixed crash with link386 and unresolved symbols.
|
|---|
| 906 |
|
|---|
| 907 |
|
|---|
| 908 | v3.2.2 Beta 2:
|
|---|
| 909 | --------------
|
|---|
| 910 |
|
|---|
| 911 | A few bugfixes and a some new features (as usual).
|
|---|
| 912 |
|
|---|
| 913 | o Added file locking support to LIBC.
|
|---|
| 914 |
|
|---|
| 915 | o Fixed _System and _Optlink bugs and made _Optlink support
|
|---|
| 916 | floating point argument passing in registers.
|
|---|
| 917 |
|
|---|
| 918 | o Header updates related to limits and file locking primarily.
|
|---|
| 919 |
|
|---|
| 920 | o Timezone fixes.
|
|---|
| 921 |
|
|---|
| 922 | o Fixed some CRT init trouble in regards to getenv and putenv.
|
|---|
| 923 |
|
|---|
| 924 | o And some other minor stuff..
|
|---|
| 925 |
|
|---|
| 926 |
|
|---|
| 927 | v3.2.2 Beta 1:
|
|---|
| 928 | --------------
|
|---|
| 929 |
|
|---|
| 930 | A few bugfixes and a some new features.
|
|---|
| 931 |
|
|---|
| 932 | o Locale support in libc.
|
|---|
| 933 |
|
|---|
| 934 | o Implemented a different approach to OMF and weak symbols. This
|
|---|
| 935 | new hack performs pre-linking before invoking the OMF linker
|
|---|
| 936 | generating new .def files if needed and an extra object file with
|
|---|
| 937 | aliases to resolve the weak symbols correctly.
|
|---|
| 938 | The old approach will be used used when GCC_WEAKSYMS is present in
|
|---|
| 939 | the environment.
|
|---|
| 940 |
|
|---|
| 941 | Please note that due to a bug in BFD, weak symbols don't work
|
|---|
| 942 | 100% correctly. This will be addressed as soon as we have
|
|---|
| 943 | performed the switch to a more recent version of binutils.
|
|---|
| 944 |
|
|---|
| 945 | o A couple of new functions in libc, and a few corrections to
|
|---|
| 946 | existing in respect to namespaces.
|
|---|
| 947 |
|
|---|
| 948 | o Addressed issues with calling conventions. We now detect
|
|---|
| 949 | incompatible calling conventions, emitting warnings and errors
|
|---|
| 950 | where appropriate.
|
|---|
| 951 |
|
|---|
| 952 | o _Optlink is much better, but there are still some issues
|
|---|
| 953 | left. Passing prototyped floating point parameters to
|
|---|
| 954 | _Optlink doesn't work. Mixing of parameters which go into
|
|---|
| 955 | registers (eax, edx, ecx) and parameters which
|
|---|
| 956 | don't - void foo(int eax, struct sss s, int edx) - doesn't
|
|---|
| 957 | work. All these issues are being addressed and are expected
|
|---|
| 958 | to be fixed in the next build.
|
|---|
| 959 |
|
|---|
| 960 | o Changed GCC to link with shared libc by default. This means
|
|---|
| 961 | that in order to link with the static libc one has to specify
|
|---|
| 962 | -static. It also means that -Zmtd or -Zcrtdll are no longer
|
|---|
| 963 | required for linking with shared libc and can be removed from
|
|---|
| 964 | all makescripts.
|
|---|
| 965 |
|
|---|
| 966 | o Changed EMXOMFLD defaults to ilink from Visual Age for C++
|
|---|
| 967 | v3.6.5 or later (preferably later). The emxomfld usage output
|
|---|
| 968 | will instruct you on how to use older linkers. For VAC308 and
|
|---|
| 969 | VAC365 linkers /dbgpack is specified if debuginfo is to be
|
|---|
| 970 | generated. Emxomf checks for EMXOMFLD_TYPE=link386 when choosing
|
|---|
| 971 | debug info level.
|
|---|
| 972 |
|
|---|
| 973 | o Shipping three extra libc dlls:
|
|---|
| 974 | libc02.dbg: Unstripped version of libc02.dll. This is
|
|---|
| 975 | identical except from the presense of debug
|
|---|
| 976 | info.
|
|---|
| 977 | libc02.prf: Linked together from profiled enabled
|
|---|
| 978 | libraries using kProfiler.
|
|---|
| 979 | libc02.elh: Standard libc but linked with an external
|
|---|
| 980 | electrical fence heap from kLibDbg.
|
|---|
| 981 | These libc02.* dlls can be used instead of libc02.dll. kLibDbg
|
|---|
| 982 | and kProfiler is available in separate zip files at same
|
|---|
| 983 | location as the rest of the InnoTek GCC suite. However these
|
|---|
| 984 | external tools are provided as is. (I might actually not find
|
|---|
| 985 | time to put them out yet.)
|
|---|
| 986 |
|
|---|
| 987 | o Distribution is splitted into several zips:
|
|---|
| 988 | -core.zip: All you really need.
|
|---|
| 989 | -dbg.zip: Map files, unstripped tools and libs, and
|
|---|
| 990 | libc02.elh.
|
|---|
| 991 | -prf.zip: Profiling libraries and libc02.prf.
|
|---|
| 992 | libc.zip: The runtime libraries. (included in core.)
|
|---|
| 993 | The big zip is everything.
|
|---|
| 994 |
|
|---|
| 995 | v3.2.2 Alpha 3:
|
|---|
| 996 | ---------------
|
|---|
| 997 |
|
|---|
| 998 | Primarily bugfixes.
|
|---|
| 999 |
|
|---|
| 1000 | o Changed code generator for floating point truncations (double
|
|---|
| 1001 | to int casts and such) so PM can freely mess up the fpu status.
|
|---|
| 1002 |
|
|---|
| 1003 | o We were using the wrong float.h in two sense. We're now using
|
|---|
| 1004 | the correct one which includes all the PC defines and
|
|---|
| 1005 | prototypes.
|
|---|
| 1006 |
|
|---|
| 1007 | o Fixed a few issues with error defines and tcpip.
|
|---|
| 1008 | Note that some of the error defines have changed value in the
|
|---|
| 1009 | process so we could become compatible with the tcpip stack
|
|---|
| 1010 | and FreeBSD.
|
|---|
| 1011 |
|
|---|
| 1012 | o Corrected bugs in a number of headers.
|
|---|
| 1013 |
|
|---|
| 1014 | o Added more OS/2 prototypes and imports. There is still work
|
|---|
| 1015 | left on the header part,
|
|---|
| 1016 |
|
|---|
| 1017 | o Optimized emxomf debug info conversion.
|
|---|
| 1018 |
|
|---|
| 1019 | o Wrapped bsdselect for BSD 4.4 header mode to implement
|
|---|
| 1020 | bsdselect().
|
|---|
| 1021 |
|
|---|
| 1022 | o .... what did we forget...
|
|---|
| 1023 |
|
|---|
| 1024 |
|
|---|
| 1025 | v3.2.2 Alpha 2:
|
|---|
| 1026 | ---------------
|
|---|
| 1027 |
|
|---|
| 1028 | A few bugfixes and a couple of new features.
|
|---|
| 1029 |
|
|---|
| 1030 | o The TCP/IP headers and libraries scheme have been changed.
|
|---|
| 1031 | The default is the current OS/2 tcpip toolkit (BSD 4.4 based).
|
|---|
| 1032 | To target the older OS/2 tcpip stack (BSD 4.3 based) you must
|
|---|
| 1033 | define TCPV40HDRS before including any TCP/IP headers and make
|
|---|
| 1034 | sure usr/lib/tcpipv4 is searched before usr/lib (this is to
|
|---|
| 1035 | get the right libsocket). It is recommended to use the -D
|
|---|
| 1036 | compiler option for the define and either the LIBRARY_PATH or
|
|---|
| 1037 | the -L compiler/linker option for the library.
|
|---|
| 1038 |
|
|---|
| 1039 | o There are a couple of new and updated based on FreeBSD 5.1.
|
|---|
| 1040 | sys\stdint.h and inttypes.h (and a few internal once) are new.
|
|---|
| 1041 | sys\types.h and unistd.h are the ones most heavily updated.
|
|---|
| 1042 | We're working on getting the headers and libc in a better
|
|---|
| 1043 | shape standardwise to easy compatability and portability.
|
|---|
| 1044 |
|
|---|
| 1045 | o A infinite loop in emxomf has been fixed.
|
|---|
| 1046 |
|
|---|
| 1047 | o Linker error on sopen() has been corrected.
|
|---|
| 1048 |
|
|---|
| 1049 | o .... what did we forget...
|
|---|
| 1050 |
|
|---|
| 1051 |
|
|---|
| 1052 | v3.2.2 Alpha 1:
|
|---|
| 1053 | ---------------
|
|---|
| 1054 |
|
|---|
| 1055 | This is the first release from InnoTek, and it contains the InnoTek LIBC.
|
|---|
| 1056 | In addition to the new LIBC there is a number of other major changes:
|
|---|
| 1057 |
|
|---|
| 1058 | o Name mangling in OMF mode have changed.
|
|---|
| 1059 | Until this release emxomf used to pretty much strip one leading '_'
|
|---|
| 1060 | from symbols when converting them to omf. This is now longer done
|
|---|
| 1061 | chiefly in order to correctly support mangling calling conventions
|
|---|
| 1062 | like __stdcall and __cdecl. This change have the following side
|
|---|
| 1063 | effects:
|
|---|
| 1064 | - _System and __cdecl no longer produces the same names and hence
|
|---|
| 1065 | all OS/2 API which are _System must be declared as _System in
|
|---|
| 1066 | order to link.
|
|---|
| 1067 | - Assembly code might need an extra underscore to work, or
|
|---|
| 1068 | perhaps change the prototypes to _System.
|
|---|
| 1069 | - Global variables are prepended and underscore, so mixing VAC and
|
|---|
| 1070 | GCC, or accessing globals from asm, take care.
|
|---|
| 1071 | (MSC v6.0 does this too, so it's not any uncommon practise.)
|
|---|
| 1072 |
|
|---|
| 1073 | The OS/2 headers which are included are all updated to use _System.
|
|---|
| 1074 |
|
|---|
| 1075 | o TCPIP headers are updated a quite a bit to match the toolkit ones
|
|---|
| 1076 | and to reflect the fact that the new libc does not a having common
|
|---|
| 1077 | handle space for files and sockets. These changes aren't 100%
|
|---|
| 1078 | completed yet, and usage probably will uncover some issues left in
|
|---|
| 1079 | there. Also for the programmer there is the following changes in
|
|---|
| 1080 | the apis provided:
|
|---|
| 1081 | - TCPV40HDRS are supported and should work like with the toolkit
|
|---|
| 1082 | headers. It will alias all functions to tcpip40_ editions
|
|---|
| 1083 | (using #defines) so we get the right imports thru -llibsocket.
|
|---|
| 1084 | - There is no support for sockets in select(). To do select on
|
|---|
| 1085 | sockets you will have to use bsdselect() or os2_select().
|
|---|
| 1086 | bsdselect() is only available for TCPV40HDRS. For
|
|---|
| 1087 | !defined(TCPV40HDRS) fd_set is in the emx/bsd format and not the
|
|---|
| 1088 | OS/2 tcpip v5.0 format.
|
|---|
| 1089 | - Socket IOCTLs are not supported by the ioctl() libc function
|
|---|
| 1090 | because of the separate handle space for sockets. For sockets
|
|---|
| 1091 | so_ioctl() and os2_ioctl() are used. os2_ioctl() is not available
|
|---|
| 1092 | when TCPV40HDRS is defined. According to the tcpref in v5.0
|
|---|
| 1093 | so_ioctl() only supports BSD ioctls.
|
|---|
| 1094 | - writev() and readv() also clashes with libc. For socket handles
|
|---|
| 1095 | use so_writev() and so_readv().
|
|---|
| 1096 |
|
|---|
| 1097 | o The prefered OMF linker is now ilink. link386 will fail with an odd
|
|---|
| 1098 | error message if you tell gcc/g++ to make debug info. Set the
|
|---|
| 1099 | EMXOMFLD_LINKER environment variable to value ilink in order to use
|
|---|
| 1100 | ilink as OMF linker.
|
|---|
| 1101 | It likely that we will change the default OMF linker to ilink in an
|
|---|
| 1102 | later version of the GCC suite.
|
|---|
| 1103 |
|
|---|
| 1104 | o .... what did we forget...
|
|---|
