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.

Hi Erik,
I'm not sure why the NIOS support is not in uClibc -- perhaps the patch
was rejected or never submitted? In any case, I'm playing with some NIOS
stuff and created this patch against 0.9.26. The work was done by
Microtronix. I'm not sure who else contributed to it. It would be great
to have the NIOS support available in uClibc so developers don't have to
go searching for these bits.

Add timegm() function.
Make lookup_tzname() static (as it should have been).
Have strftime() get timezone information from the passed struct
for the %z and %Z conversions when using struct tm extensions.

This patch adds code to uClibc to support a new ABI designed for the
FR-V architecture, that enables text segments of executables and
shared libraries to be shared by multiple processes on an OS such as
uClinux, that can run on FR-V processors without an MMU.
Patches for binutils and GCC have just been posted in the
corresponding mailing lists. The binutils patch was approved,
but there's one additional patch pending review, that I posted
this week. An updated GCC patch will be posted to
gcc-patches@gcc.gnu.org as soon as I complete testing (I used a
known-good compiler to test the uClibc patch below).
Since the existing dynamic loader code didn't support independent
relocation of segments, it required changes that were somewhat
extensive. I've added a number of new machine-specific macros to try
to keep the platform and ABI-specific details outside the generic
code. I hope this is not a problem.

While testing the FR-V code with GCC mainline, I ran into some
problems in the RPC code. It relies on a GCC extension that is no
longer available, namely, the result of a cast is no longer considered
an lvalue.
This patch enables the code to compile. I haven't been able to test
RPC though, especially in a multi-threaded environment.

Codepaths streamlined. Improved performance for nonthreaded apps
when linked with a thread-enabled libc.
Minor iconv bug and some locale/thread related startup issues fixed.
These showed up in getting a gcj-compiled java helloworld app running.
Removed some old extension functions... _stdio_fdout and _stdio_fsfopen.

were including libc-lock.h which had a bunch of weak pragmas. Also,
uClibc supplied a number of no-op weak thread functions even though
many weren't needed. This combined result was that sometimes the
functional versions of thread functions in pthread would not override
the weaks in libc.
While fixing this, I also prepended double-underscore to all necessary
weak thread funcs in uClibc, and removed all unused weaks.
I did a test build, but haven't tested this since these changes are
a backport from my working tree. I did test the changes there and
no longer need to explicitly add -lpthread in the perl build for
perl to pass its thread self tests.

Nothing overly interesting here, this renames Hitachi/Mitsubishi to Renesas
for the relevant platforms (in this case, h8, sh, and m32r). The same changes
have already been going on in gcc/binutils/gdb/glibc/etc.

I found inappropriate data types are used in some places in networking
codes.
* tcp_seq is 32bit (u_long -> u_int32_t)
* in_addt_t should be used for internet address (unsigned long -> in_addr_t)
* socklen_t should be used for accept()
This is a patch against uclibc-0.9.21 (can be applied for current
CVS). 64bit platforms (sizeof(int)!=sizeof(long)) will need this. I
believe this patch does not harm any 32bit platforms.

Add in a SUSv3 getopt as an option for those not needing gnu getopt.
Again, mainly for the static linking crowd.

Also don't install printf.h if glibc custom printf specifier support

Hack a fix for ctype support of 8-bit codeset locales.
Note: toupper/tolower mappings do not handle the special cases for the
tr_TR and az_AZ locales, since the wide versions currently handle them
either. That will be addressed when I rewrite the data generation tools
and the libc locale code.

Move stub gettext functions to a stub libintl to make switching in
gnu gettext easier. Also add a few gnu-isms.
Change to using hidden names with global weak aliases for the extended
locale functions, as expected by libstd++.
Slightly rework the locale data generation stuff to allow pregenerated
locale data to be used with buildroot.
