with my config (no locale, the rest enabled). Not tested if libc is complete and usable. All the files listed in *_NO_MULTI need love, best would be to replace all multisources w/ single sources.

not exist, we reinclude the including Makefile. Moved arch/common fpu_control.h link creation into main Makefile.in. Updated the link creation script to remove all the other Makefiles

archs lack proper crt1. The Makefiles in extra/scripts are intended to be linked into each dir, where it is necessary to build locally.

objects at once; use :=//$</$^; use CRT_SRC/CRT_OBJ/SCRT_OBJ/CSRC/COBJ/SSRC/SOBJ/MSRC/MOBJ where no more is needed, if only CSRC is present use OBJS directly instead of COBJ; CTOR_TARGETS are created directly in lib; remove unused/unneeded parts. Hope I haven't broken too much.

perl tests fail on mipsel.

Unfortunatly, the semid_ds structs were not changed as needed. So
import the necessary (tweaked) files from glibc. Only tested on x86
today, but I'll be testing mips tomorrow.

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.

'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'.

see http://uclibc.org/lists/uclibc/2005-May/011667.html for details.
Not tested by me but I am sure Peter will :)
The toolchain needs to be rebuilt.

Hmm... I found a old fix in uClibc ML archive.
http://www.uclibc.org/lists/uclibc/2002-September/004459.html
But it seems somewhat broken. How about this fix instead? I tested
mmap with syscall() in mips. mips64 is not tested.

In a recent post to linux-mips ML (and libc-alpha ML), a problem with
inline syscalls was reported.

It seems uClibc should be fixed also for newer gcc. Here is a patch.

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.

instruction errors. Disable it for now.

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.

This is a patch for uClibc/libc/sysdeps/linux/mips/sys/procfs.h pulled
from glibc CVS.
This fixes gdb with threaded application (with glibc environment).
Although debugging threaded programs seems not working on uClibc/mips
yet, this patch will be required when it becomes working.
This patch can be applied to any version of uClibc (including current
CVS).

have it. It is used by the boehm gc, amoung other things.

which prevents libthread_db (used by gdb) from compiling. Include a
copy within include/sys/user.h for mips, per what was done in glibc.
