be able to run apps built with 0.9.27. This also renames __uClibc_start_main to __uClibc_main. This compat option should be removed some time after 0.9.28 is released. Let me know if you don't like this change.

__libc_csu_init and _fini vs. __libc_csu_fini remains to do.
2005-05-21Pass main function ptr from crt1 to __uClibc_start_main.Joakim Tjernlund
Kill old crt0/__uClibc_main. This breaks ABI. All apps and toolchain needs to be recompiled. All archs except x86 are now broken and need to be fixed as x86. PPC will be fixed shortly by me, the rest is left to the arch maintainers.
2005-05-12Added new 'bits/atomic.h' for most of the architectures and the top-level ↵"Steven J. Hill"
'include/atomic.h' to add in new atomic operations for use by NPTL. There are multiple files for PowerPC and Sparc for 'atomic.h'. I will let those architecture maintainers choose the correct file. The files come from glibc in 'sysdeps/ARCH/bits'.
2005-03-20Pass _dl_fini function ptr to __uClibc_start_main().Joakim Tjernlund
To actually use it, one must define _DL_DO_FINI_IN_LIBC globally. That will also break ABI for apps linked with previous version of crtX.S. They must be relinked with this version to work again.

2004-12-22Patch from Peter S. Mazinger to consistantly use "ASFLAGS"Eric Andersen

2004-10-14Peter Mazinger writes:Joakim Tjernlund
The attached patch generalizes the use of PIE (all archs are brought in sync that use/mention it: x86/ppc/frv) and makes use of it building the target utils. Tested on x86, ppc should be tested, frv uses -fPIE at one location, but at another place -fpie, I don't know which is correct (could be both) and misses the target addition in Config.in. The test for ppc (requires the earlier sent crt-correction patch to work correctly): enable UCLIBC_PIE_SUPPORT, build uClibc and utils, check: file ./utils/ldd, it should show shared object (instead of executable)
2004-08-21Kill off all support for 'gcc -pg' / 'gprof' style profiling. There is both aEric Andersen
size and performance penalty to profiling applications this way, as well as Heisenberg effects, where the act of measuring changes what is measured. There are better tools for doing profiling, such as OProfile, that do not require gcc to instrument the application code. -Erik

2004-07-30Cleanup some dead wood in the header filesEric Andersen
2004-07-30s/___brk_addr/__curbrk/gEric Andersen
Some utilities, such as valgrind, have a legitimate reason to know the address of the current brk. Since we know such utils will peek under our skirt, we might as well give them what they expect and not use a gratuitously different symbol name. -Erik
2004-06-12Per comments from Bernhard Rosenkraenzer, adjust gcc 3.3.x generated asmEric Andersen
with s/i686.get_pc_thunk.bx/get_pc_thunk_bx/g to make gcc 3.4 happy.

have it. It is used by the boehm gc, amoung other things.
2004-04-20Cope with gcc 3.4's more aggressive persuit of attribute unusedEric Andersen
2004-02-06Sigh. The 2.6.x kernel removed '__kernel_dev_t' and renamed it asEric Andersen
'__kernel_old_dev_t'. And of course there is no good way to know which is in use except checking linux/version.h. Grumble. This is rather lame, but for now, define __kernel_old_dev_t to be the same as __kernel_dev_t. This will want to be revisited soon. -Erik
2004-01-17Add __data_start needed by boehm garbage collector, in turn needed by libgcj.Manuel Novoa III

2004-01-03Minor changesEric Andersen
2004-01-02Peter S. Mazinger writes:Eric Andersen
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
2003-12-03Lethal noticed that the generated file gmon-start.S was notEric Andersen
being cleaned up.
2003-11-22Remove SAFECFLAGS. It was a workaround for failures in old awk scriptEric Andersen
used to generate the crti.S and crtn.S files. Since we don't use that anymore, keeping the workaround makes no sense. Furthermore, in most cases, SAFECFLAGS was not picking up all the needed flags, causing crti.o and crtn.o to not be built PIC. Which is very bad. Removing SAFECFLAGS and using CFLAGS fixes that as well.
2003-11-08Darn. Fix compilation for soft-float, which I inadvertantlyEric Andersen
broke a couple of days ago. :-(

ln.patch: * Define $(LN) as ln in Rules.mak. * Change all occurrences of ln into $(LN). * Change all constructs like (cd path && ln -sf foo/file file) into $(LN) -sf foo/file path/file. The latter construct is already used in a number of places so it should not be an additional compatibility problem.

2003-10-08Patch from Atsushi Nemoto (with some additions):Eric Andersen
Current uClibc contains only one fpu_control.h and it is i386 version. This is a patch to use platform specific fpu_control.h. All new files come from glibc 2.3.2. This patch is against 0.9.21 but also can be applied to CVS as is.

2003-09-07Some updates from glibc. mjn3 reports this fixes profilingEric Andersen
on i386, at least, so seems like a good thing.
2003-09-07i386/mcount.S expects to call __mcount_internal with the 2 args passedManuel Novoa III
in registers. NOTE: i386/mcount.S really needs to be rewritten. It currently won't work for non-PIC builds.
