| | | | | | | | | | | | | | | | | | | Hello Erik! I have made some cosmetical changes to the files, removed the added SCRT=-fPIC option from building the crt0.S file (but it is a requirement to build them with -fPIC), and changed some comments. I have left the ldso.c patch with PIE_SUPPORT ifdefs, but consider applying it w/o them (see some earlier comment from PaX Team on this issue, as it is considered a bug). To have it work correctly, you'll also need removing COMPLETELY_PIC. One thing is missing: PIE_SUPPORT should be usable only for i386 (for now). Also added the support for propolice protection (that works for me and catches memcpy/strcpy attacks (but needs a special gcc version). Thanks, Peter
* Handle the app_fini stuff in exit without requiring atexit().Manuel Novoa III2003-12-271-3/+4

* Making atexit weak does nothing for dynamicly linked apps. And forEric Andersen2003-01-231-3/+5
| | | | | | | | | | staticly linked apps it entirely prevents destructors from running unless atexit is called for some other reason. So if they enabled ctor/dtor support we need to have a call to the real atexit for dtors to work properly. If people don't want the extra 4k or so of junk in their static apps, they should leave ctor/dtor support disabled. -Erik
* This commit contains a patch from Stefan Allius <allius@atecom.com> to changeEric Andersen2002-10-011-56/+111
| | | | | | | how uClibc handles _init and _fini, allowing shared lib constructors and destructors to initialize things in the correct sequence. Stefan ported the SH architecture. I then ported x86, arm, and mips. x86 and arm are working fine, but I don't think I quite got things correct for mips.

* New locale support (in development). Supports LC_CTYPE, LC_NUMERIC,Manuel Novoa III2002-05-061-0/+12
| | | | | | | | | | | | | | | | | | | | | | LC_TIME, LC_MONETARY, and LC_MESSAGES for the SUSv3 items. Also, nl_langinfo() when real locale support is enabled. New implementation of ctype.h. New implementation of wctype.h. New implementation of most of the string functions (smaller). New implementation of the wcs/wmem functions. These are untested, but they're also just preprocessor-modified versions ot the corresponding str/mem functions. Tweaked qsort and new bsearch. Stuff still pending: stdlib.h and wchar.h mb<->wc functions. I actually have working versions of the stdlib ones, but the reentrant versions from wchar.h require some reworking. Basic replacement and translit support for wc->mb conversions. (groundwork laid). Simple-minded collate support such as was provided by the previous locale implementation. (mostly done -- 8-bit codesets only) Shared mmaping of the locale data and strerror message text.
* Patch from Martin Proulx to remove weak_aliases for non ELF compilers inEric Andersen2002-04-171-2/+2
| | | | | | __uClibc_main for the _stdio_init and _stdio_term functions. Since weak_aliases are defined as hard aliases for non ELF compilers, these 2 symbols ended up to be multiply defined, as those two are defined in stdio.c.
* Patches from Yoshinori Sato <qzb04471@nifty.ne.jp> to fix h8300Eric Andersen2002-04-011-0/+3

* Fix include/errno.h to not use kernel header, and instead use bits/errno.h.Eric Andersen2001-04-061-1/+1
| | | | | | | This required we use _LIBC instead of __LIBC__ to be consistent with glibc. This had some sideffects in sys/syscalls.h. While fixing things, I made everything use __set_errno() for (eventual) thread support. -Erik

* Create __uClibc_main to handle what can be done in C instead of each arch'sManuel Novoa III2001-02-191-0/+80
respective crt0.S. crt0.S should now only be responsible for setting things up to call __uClibc_main(argc, argv, envp), which will do any other necessary setup (setting global __environ, stdio init, etc), call main, and exit. This should ease both maintainance and porting.
