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

This avoids pulling in all the malloc/free code for a simple true/false app.

rm.patch:
* Define $(RM) as rm -f in Rules.mak and test/Rules.mak
(this is the same definition as gmake uses by default).
* Change all occurrences of rm and rm -f into $(RM).

and so it actually works as intended allowing binaries on ARM to be
debugged.

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.

been working on a new config system on and off for about 6 months
now, but I've never been fully satisfied. Well, I'm finally am
happy with the new config system, so here it is. This completely
removes the old uClibc configuration system, and replaces it with
an entirely new system based on LinuxKernelConf, from
http://www.xs4all.nl/~zippel/lc/
As it turns out, Linus has just merged LinuxKernelConf into Linux
2.5.45, so it looks like I made the right choice.
I have thus far updated only x86. I'll be updating the other
architectures shortly.

work? Perhaps the wrapper bug miles fixed? Regardless this is very
much needed.

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.

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.

__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.
|
|
a separate header file for those, and fixup references.

a native gcc toolchain). The gcc wrapper still needs some touchups,
but we seem to be _there_. Also some touchups to try and shrink
uclinux binary sized by stubbing out unneeded stuff.

glibc 2.1.3 and ported to work with uClibc by Stefan Soucek and Erik Andersen
(me). Stefan has hacked things up such that linuxthreads runs on MMU-less
systems (tested only on arm-nommu). Erik cleaned things up and made it work
properly as a shared library.

He sent this patch to me a month ago, but I forgot to apply it...

they use as stubs, otherwise, some compilers (ie., m68k-elf) tie them to
the local symbols and the weak aliases do not work.

define, and set things up so nasty old coff toolchains can now compile
things and should actually work again.

from libm float function support. Also, move all Config files out of the
main directory.
|
|
tree is less messy now (which helps), all libraries are placed into
uClibc/lib when compiling, all libraries now use a consistant mechanism
for being built, all libraries use a consistant naming scheme where the
lib name includes the uClibc version number, which makes ldconfig
happy and willing to work with us.

the heavy lifting (most of the heavy lifting stolen from glibc,
but reduced a bit).
|
|
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.

printf now supports long double, plus some bug fixes.
|
|
I followed environ example which uses asm and it seemed to fix the problem
nicely.
It should be ok on i386. Could some check it please :-)
