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

---|
124 |
|
---|

|
---|
126 | extensions implemented.

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

306 |
|
---|
307 | Todos before LIBC06.DLL:

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

|
---|
336 |
|
---|
337 | o wchar.h and wctype.h and much of the non-stream functions

---|
338 | declared therein are implemented. Though, the FreeBSD
|
---|
339 | string/w*.c functions are still in the porting queue.
|
---|
340 |
|
---|
341 | o Added __mcount stub to all LIBC DLLs but the .prf one which
|
---|
342 | is forwarding __mcount from kProfile.dll.
|
---|
343 |
|
---|
344 | o DosLoadModuleEx and DosFreeModuleEx was created to support
|

|
---|
352 | level.

374 | Bug fixes:
|
---|
375 |
|
---|
376 | o Fixed missing WNOHANG handling in waitpid(), wait4()
|
---|
377 | and waitid().
|
---|
378 |
|
---|
379 | o Corrected several severe bugs in the path resolver.
|
---|
380 |
|
---|
381 | o Fixed handling of paths ending with slash.
|
---|
382 |
|
---|
383 | o Fixed weird fork() problem which showed up as a heap
|
---|
384 | deadlock.
|
---|
385 |
|
---|
386 | o Fixed broken _getdrive().
|
---|
387 |
|
---|
388 | o Made _chdrive() return -1 on error. It used to always
|
---|
389 | return success earlier. (don't ask me why)
|
---|
390 |
|
---|
391 | o Fixed incorrect handling of -shared in GCC. It should
|
---|
392 | be treated as -Zdll.
|
---|
393 |
|
---|
394 | o Various incorrect assertions in the strict/log build.
|
---|
395 |
|
---|
396 | o ...
|
---|
397 |
|
---|
398 | Known Limitiations/Problems:
|
---|
399 |
|
---|
400 | o Static linking not possible - might be fixed later.
|
---|
401 |
|
---|
402 | o Job control will only be applied to thread 1 in a process.
|
---|
403 | This won't change.
|
---|
404 |
|
---|
405 | o Missing some process group interfaces required for
|
---|
406 | job control. They'll show up soon I hope.
|
---|
407 |
|
---|
408 | o Not tested too well. Especially the regex update.
|
---|
409 |
|
---|
410 | Todos before LIBC06.DLL:
|
---|
411 |
|
---|
412 | 0. Fix all bugs. :-)
|
---|
413 |
|
---|
414 | 1. Implement new ino_t scheme and reimplement opendir
|
---|
415 | in BSD style while doing so (+fchdir).
|
---|
416 |
|
---|
417 | 2. Shared IPC structures for XSI msq, sem and shm.
|
---|
418 |
|
---|
419 | 3. Port string/w* functions.
|
---|
420 |
|
---|
421 | 4. Missing job pgid functions.
|
---|
422 |
|
---|
423 | 5. Port GLIBC intl/*. gettext is a pita! because it's
|
---|
424 | passing FILE pointers around between different LIBCs.
|
---|
425 | objdump is constantly broken between LIBC versions.
|
---|
426 |

429 | GCC v3.3.5 / LIBC v0.6 - Beta 1:
|
---|
430 | --------------------------------
|
---|
431 |
|
---|
432 | New features:
|
---|
433 |
|
---|
434 | o setitimer/alarm implementation. Needs some review later
|
---|
435 | the accuracy isn't extacly great.
|
---|
436 |
|
---|
437 | o Added a couple of missing os2emx.h features.
|
---|
438 |
|
---|
439 | o Some more 16-bit thunkers.
|
---|
440 |
|
---|
441 | Bug fixes:
|
---|
442 |
|
---|
443 | o Select worker called wrong tcpip function.
|
---|
444 |
|
---|
445 | o Incorrect assertion during thread destruction.
|
---|
446 |
|
---|
447 | o Fixed broken chdir and getdrive.
|
---|
448 |
|
---|
449 | o Improved deadlock detection (fmutex have changed,
|
---|
450 | thus stdio FILE is also changed).
|
---|
451 |
|
---|
452 | o ...
|
---|
453 |
|
---|
454 |
|
---|
455 | Known Limitiations/Problems:
|
---|
456 |
|
---|
457 | o Static linking not possible - will be fixed.
|
---|
458 |
|
---|
459 | o Job control will only be applied to thread 1 in a process.
|
---|
460 | This won't change.
|
---|
461 |
|
---|
462 | o Missing some process group interfaces required for
|
---|
463 | job control. They'll show up soon.
|
---|
464 |
|
---|
465 | o Doesn't evaluate trailing slash in paths as directory
|
---|
466 | specifier, it's currently ignored.

470 | GCC v3.3.5 / LIBC v0.6 - Alpha 3:
|
---|
471 | ---------------------------------
|
---|
472 |
|
---|
473 | This release have been timebombed and will stop working at the
|
---|
474 | end of December 2004. The reason for this is that data structures
|
---|
475 | shared between LIBC 0.6 and all future LIBC versions are not yet
|
---|
476 | quite finalized. (For your comfort the timebomb will go away when
|
---|
477 | the betas start, and this is the last planned LIBC v0.6 alpha.)
|
---|
478 |
|
---|
479 |
|
---|
480 | New Features:
|
---|
481 |
|
---|
482 | o Updated GCC to version 3.3.5.
|
---|
483 |
|
---|
484 | o Replaced the signal implementation. The new implementation
|
---|
485 | is much closer to the POSIX specs and implements a lot of
|
---|
486 | new interfaces.
|
---|
487 |
|
---|
488 | o Experimental delayed loading import libraries. emximp have
|
---|
489 | a new -l option for generating such libraries. At present
|
---|
490 | emximp can only generate a.out libraries of this kind - so
|
---|
491 | use emxomf to convert to OMF.
|
---|
492 |
|
---|
493 | o The dlfcn.h functions are in LIBC now.
|
---|
494 |
|
---|
495 | o New functions:
|
---|
496 | getgrouplist(), initgroups(), memalign(), valloc(),
|
---|
497 | mprotect(), _signal_os2(), _signal_sysv(),
|
---|
498 | __sigpause_bsd(), bsd_signal(), killpg(), psignal(),
|
---|
499 | sigaltstack(), sigblock(), sighold(), sigignore(),
|
---|
500 | siginterrupt(), sigpause(), sigrelse(), sigsetmask(),
|
---|
501 | sigtimedwait(), sigvec(), sigwait(), sigwaitinfo(),
|
---|
502 | sigqueue(), sigset(), getgrgid(), getpwnam(),
|
---|
503 | getpwuid(), setegid(), seteuid(), setregid(),
|
---|
504 | setresgid(), setresuid(), setreuid(),
|
---|
505 | setrgid(), setruid(), waitid(), wait3(),
|
---|
506 | wait4() and getopt_long_only().
|
---|
507 |
|
---|
508 |
|
---|
509 | Bug fixes;
|
---|
510 |
|
---|
511 | o Sockets were broken on some systems. Hopefully, this
|
---|
512 | should be corrected now.
|
---|
513 |
|
---|
514 | o stat() failed on a file open for writing.
|
---|
515 |
|
---|
516 | o fork() didn't work for processes which allocated lot's
|
---|
517 | of memory. Fixed incorrect syncing of memory objects.
|
---|
518 |
|
---|
519 | o ...
|
---|
520 |
|
---|
521 |
|
---|
522 | Known Limitiations/Problems:
|
---|
523 |
|
---|
524 | o Static linking not possible - will be fixed.
|
---|
525 |
|
---|
526 | o alarm() is still missing. Code is 80% done but didn't
|
---|
527 | make it for the release.
|
---|
528 |
|
---|
529 | o Job control will only be applied to thread 1 in a process.
|
---|
530 | This won't change.
|
---|
531 |
|
---|
532 | o Missing some process group interfaces required for
|
---|
533 | job control. They'll show up soon.
|
---|
534 |
|
---|
535 |
|
---|

|
---|
537 | GCC v3.3.4 / LIBC v0.6 - Alpha 2:
|
---|
538 | ---------------------------------
|
---|
539 |
|
---|
540 | This release have been timebombed and will stop work at the
|
---|
541 | end of October 2004. The reason for this is that data structures
|
---|
542 | shared between LIBC 0.6 and all future LIBC versions are not yet
|
---|
543 | finalized.
|
---|
544 |
|
---|
545 |
|
---|
546 | New Features:
|
---|
547 |
|
---|
548 | o Updated GCC to version 3.3.4.
|
---|
549 |
|
---|
550 | o 2nd fork() implementation.
|
---|
551 | All binaries are by default forkable, use the link option
|
---|
552 | -Zno-fork to disable this.
|
---|
553 | The fork implementation rendered _rmutex useless and it
|
---|
554 | has been removed.
|
---|
555 |
|
---|
556 | o Symlinks using EAs. This is work in progress. One of the
|
---|
557 | limitiations is that readir will not report DT_LNK yet.
|
---|
558 |
|
---|
559 | o Unix compartment using chroot(). This offers a
|
---|
560 | redirection of '/' to the chroot'ed root. The entrance
|
---|
561 | to the compartment is the '/'. The exits are drive letters.
|
---|
562 | The unix compartment is inherited by LIBC child processes.
|
---|
563 |
|
---|
564 | o getcwd() will now return the driveletter too (as VAC does)
|
---|
565 | when not inside the unix compartement.
|
---|
566 | _getcwdux() has been provided for porters which requires
|
---|
567 | behaviour like the old getcwd() implementation.
|
---|
568 |
|
---|
569 | o Paths to unix files #defined in headers are now prefixed
|
---|
570 | with "/@unixroot" which will be redirected to where the
|
---|
571 | environment variable UNIXROOT points. After calling
|
---|
572 | chroot() the target of "/@unixroot" will be changed too.
|
---|
573 |
|
---|
574 | o LIBC specific path rewriting (redirection). Built in is
|
---|
575 | "/dev/null", "/dev/tty" and "/@unixroot".
|
---|
576 | The environment variable LIBC_PATHREWRITERS is examined
|
---|
577 | during init and DLLs specified in it are loaded and called.
|
---|
578 | See src/emx/src/sys/pathrewrite.c for more details.
|
---|
579 |
|
---|
580 | o Non-unix like mode - link option -Zno-unix.
|
---|
581 | This affects slashes and various other Unix-like features
|
---|
582 | like for instance fork and symlinks.
|
---|
583 |
|
---|
584 | o Printf et al. have been extended to support some new format
|
---|
585 | specifiers. (It's still lacking a bit to be SuS comforming.)
|
---|
586 |
|
---|
587 | o Sockets handles are now inherited by LIBC child processes.
|
---|
588 |
|
---|
589 | o LIBC specific filehandle flags are now inherited by LIBC
|
---|
590 | child processes.
|
---|
591 |
|
---|
592 | o The GCCxyz.DLL is no longer needed when LIBC is used.
|
---|
593 | However it is still shipped for special cases where LIBC
|
---|
594 | isn't needed.
|
---|
595 |
|
---|
596 | o A good bunch of 'new' functions both from the SuS and from
|
---|
597 | various Unix flavors, even one or two PC functions have been
|
---|
598 | added. Accompanying these are new headers and header updates.
|
---|
599 | Here are most of the new function names:
|
---|
600 | __strverscmp(), _atfork_callback(), _getcwdux(),
|
---|
601 | _getdcwd(), _nsdbtaddsrc(), _nsdbtput(), _nsdispatch(),
|
---|
602 | _realrealpath(), canonicalize_file_name(), catclose(),
|
---|
603 | catgets(), catopen(), chown(), chroot(), eaccess(),
|
---|
604 | endgrent(), endnetgrent(), endusershell(), fchown(),
|
---|
605 | fstatfs(), fstatvfs(), getdtablesize(), getfsstat(),
|
---|
606 | getgrent(), getgrent_r(), getgrgid_r(), getgrnam_r(),
|
---|
607 | getloadavg(), getmntinfo(), getnetgrent(),
|
---|
608 | getpwent_r(), getpwnam_r(), getpwuid_r(), getrlimit(),
|
---|
609 | getusershell(), innetgr(), lchown(), link(), mknod(),
|
---|
610 | readlink(), setgrent(), setgroupent(), setgroups(),
|
---|
611 | setnetgrent(), setpassent(), setrlimit(),
|
---|
612 | setusershell(), sl_add(), sl_find(), sl_free(),
|
---|
613 | sl_init(), statfs(), statvfs(), strmode(), strtok_r(),
|
---|
614 | symlink() and sync().
|
---|
615 |
|
---|
616 |
|
---|
617 | Bug fixes:
|
---|
618 |
|
---|
619 | o setlocale() have been rewritten. The code page is now
|
---|
620 | taken from the locale rather than OS/2. Old behaviour
|
---|
621 | is used if environment variable LIBC_SETLOCALE_OLDSTYLE
|
---|
622 | is defined.
|
---|
623 |
|
---|
624 | o Buggy strspn() replaced by BSD implementation.
|
---|
625 |
|
---|
626 | o Thread backend have been reworked fixing certain
|
---|
627 | problems when LIBC was loaded and initialized in threads
|
---|
628 | other than the primary one. A LIBC specific TLS api
|
---|
629 | was created during this effort.
|
---|
630 |
|
---|
631 | o Fixed a missing export from GCCxyz.dll which was causing
|
---|
632 | incorrect behaviour of C++ exceptions in all previous
|
---|
633 | releases.
|
---|
634 |
|
---|
635 | o Fixed a buffer overrun in iconv_open() which caused a
|
---|
636 | corruption of the FS selector register, thus crashing
|
---|
637 | the processing.
|
---|
638 |
|
---|
639 | o ...
|
---|
640 |
|
---|
641 |
|
---|
642 | Known limitations and bugs:
|
---|
643 |
|
---|
644 | o mktime() works incorrectly for exterme values causing
|
---|
645 | configure test to fail.
|
---|
646 |
|
---|
647 | o NSS probably doesn't work.
|
---|
648 |
|
---|
649 | o Trailing slashes of a path specification are not
|
---|
650 | handled correctly after the rewrite of the path
|
---|
651 | handling.
|
---|
652 |
|
---|
653 | o New path handling is not DBCS ready.
|
---|
654 |
|
---|
655 | o Socket handle duplication have not been implemented yet.
|
---|
656 |
|
---|
657 | o The __<syscall> function are in the process of being
|
---|
658 | removed.
|
---|
659 |
|
---|
660 | o Not tested with mozilla.
|
---|
661 |
|
---|
662 |
|
---|
663 |
|
---|
664 | v3.2.2 Beta 4 CSD 1:
|
---|
665 | --------------------
|
---|
666 |
|
---|
667 | Bug fixes:
|
---|
668 |
|
---|
669 | o Fixed crash in file stream allocation code.
|
---|
670 |
|
---|
671 | o Fixed incorrect time on machines which had DATETIME::timezone
|
---|
672 | set. This fix changes the time granularity from hundredths of
|
---|
673 | a second to milliseconds.
|
---|
674 |
|
---|
675 | o Added the SPBCDATA struct, the defines FCF_CLOSEBUTTON and
|
---|
676 | BS_NOTEBOOKBUTTON and infosegment structs to os2emx.h
|
---|
677 |
|
---|
678 | o Fixed bug in sys/locale.h where it hid the lconv struct.
|
---|
679 |
|
---|
680 | o Fixed missing error number translations in getsockopt() and
|
---|
681 | setsockopt().
|
---|
682 |
|
---|
683 | o Fixed potential conflict caused by sys/types.h not defining
|
---|
684 | _KEY_T with the key_t typedef.
|
---|
685 |
|
---|
686 | o Fixed missing 64bit I/O support in ftell(), fstat() and stat().
|
---|
687 |
|
---|
688 | o Fixed UCS-2 codepage mappings.
|
---|
689 |
|
---|
690 | o Fixed problem with emxbind not recognizing option -e and
|
---|
691 | a problem with case sensitivity in the export checking.
|
---|
692 |
|
---|
693 |
|
---|
694 | v3.2.2 Beta 4:
|
---|
695 | --------------
|
---|
696 |
|
---|
697 | (The changelog is removed, thus the release notes are more detailed.)
|
---|
698 |
|
---|
699 | New features and fixes:
|
---|
700 |
|
---|
701 | o Filehandle rewrite. Files, pipes and sockets now share the same
|
---|
702 | handle space.
|
---|
703 |
|
---|
704 | o Updated binutils from v2.11.2 to v2.14 adding as-elf.exe and
|
---|
705 | ld-elf.exe as goodies for the adventurous.
|
---|
706 |
|
---|
707 | o GCC defines __INNOTEK_LIBC__=0x005.
|
---|
708 | The value reflects the LIBC version, form: 0xGMM
|
---|
709 | Where G=major version and MM=middle version numbers.
|
---|
710 |
|
---|
711 | o Changed library search algorithms for the linkers (emxomfld
|
---|
712 | and ld). Three variations, static, shared and shared+dll.
|
---|
713 | (The options indicated corresponds to what binutils 2.12.x
|
---|
714 | documents.)
|
---|
715 | static: (-Bstatic, -non_shared, -dn, -static)
|

741 | o Added feature to emxomfld to automatically convert a.out
|
---|
742 | libraries and objects to OMF (using temporary files). Enabled

|
---|
767 |
|
---|
768 | o Changed size_t to unsigned int (from unsigned long int) and
|
---|
769 | ptrdiff_t to signed int (from signed long int) to comply with
|
---|
770 | most of the other i386 environments.

|
---|
794 | specified.

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

|
---|
830 | imaxabs(), imaxdiv(), strtoimax(), strtoumax(), hcreate(),
|
---|
831 | hdestroy(), hsearch(), insque(), lfind(), lsearch(),

|
---|
858 | o New headers:
|
---|
859 | nerrno.h (toolkit compatability).
|
---|
860 |
|
---|
861 | o New headers (from FreeBSD 5.1):
|
---|
862 | search.h, sys/queue.h, net/if_types.h.
|
---|
863 |
|
---|
864 | o New headers (from GLIBC 2.3.2):
|
---|
865 | features.h (somewhat crippled),
|
---|
866 | sys/gnu/cdefs.h (included from BSD styled sys/cdefs.h).
|
---|

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