position of envp in C code based on argv and argp. No need to
caclulate that in asm for N arches. This way, we better match
what glibc does. All arches will need to be fixed to match up
with this change.

__libc_csu_init and
_fini vs. __libc_csu_fini remains to do.

ptr to crt. Only PowerPC and x86 support this currently.
|
|
|
|
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.

since we are going to support the two implementations of pthreads, we
again need to instead create symbolic links to use the proper version
of the file depending on the pthreads option chosen.
|
|
|
|
|
|
have to create symbolic links for 'semaphore.h' and 'pthread.h' which
will point to the proper pthreads directory. When we finish getting
NPTL working with uClibc, perhaps we can merge them, but a first glance
at the differences between the two does not make that very likely.

using grep because the '.config' will not get included if we are doing
a 'clean' or other targets. This was preventing the proper cleaning up
target architecture include files.
|
|
|
|
'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'.

performance timers. If you want them included in the NPTL build, copy the
header from glibc into the 'libc/sysdeps/linux/<ARCH>' of your choice and
have fun.

this one. MIPS is the only one defining SHMLBA differently.

by 'nslookup www.yahoo.com' and 'nslookup mail.hotmail.com', and thus we
currently return ERANGE when trying to lookup some of the most popular hosts on
the planet. Whether these sites deserve to be popular is a question I'll leave
for someone else to worry about.
This change makes certain we have enough static buffer space to handle about 21
IPv4 IP address replies per DNS query. Far more than enough to handle common
cases such as www.yahoo.com and mail.hotmail.com.

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.
|
|
The old sh system call interface used 0x00 - 0x0f for the trapa value
(number of arguments), whereas the new ABI uses the 0x10 - 0x1f range.
For some reason we were using an off-by-1 trapa immediate which ended up
trashing r1 in the _syscall6() case, so we fix it up..
|
|
was specific to gcc 3.3.3. Later toolchains fixed the regressions; thus, we do
not need to worry about this TODO item anymore.
|
|
consult the 'README.NPTL' file.
|
|
|
|
placing the NPTL code under the top-level 'libpthread' directory.
Nothing compiles or even works at this point, so do not enable this
option.

This popped up during a build with gcc4:

Stupid gcc.

This fix, based on this patch
http://bugs.uclibc.org/view.php?id=104
makes it so uClibc fills out round robin dns lists for
applications such as nslookup:
Before:
$ nslookup google.com
Server: mace.codepoet.org
Address: 10.10.10.1
Name: google.com
Address: 216.239.39.99
After:
$ nslookup google.com
Server: mace.codepoet.org
Address: 10.10.10.1
Name: google.com
Addresses: 216.239.57.99, 216.239.37.99, 216.239.39.99
