I found that current pread/pwrite is broken on mips.
On mips, kernel needs 6 arguments for pread/pwrite system call. (3
words for first 3 arguments + 1 padding word + 2 words for last 64bit
argument). Also, mips64 kernel needs just 4 arguments so no wrapper
will be required.
This is a patch against 0.9.20.

Here's a patch that implements the beginnings of a rudimentary sh64 port. So
far, this only works static, as I haven't done any of the ldso work yet. I've
also not touched the libpthread stuff yet either, so that's also disabled for
now.
This port was based off of some work that Sean McGoogan at SuperH did for his
initial port, but the this patch doesn't carry over too much from there
(basically the libc/sysdeps/linux/sh64/Makefile (or rather, parts of it),
the setjmp/longjmp stuff (which I had to rewrite portions of it to work with
the new toolchains), etc.).
However, for static, everything appears to work correcly, at least in a hello
world type application.

Should be standards compliant and with several optional features,
including support for hexadecimal float notation, locale awareness,
glibc-like locale-specific digit grouping with the `'' flag, and
positional arg support. I tested it pretty well (finding several
bugs in glibc's scanf in the process), but it is brand new so be
aware.
The *wprintf functions now support floating point output. Also, a
couple of bugs were squashed. Finally, %a/%A conversions are
now implemented.
Implement the glibc xlocale interface for thread-specific locale
support. Also add the various *_l(args, locale_t loc_arg) funcs.
NOTE!!! setlocale() is NOT threadsafe! NOTE!!!
The strto{floating point} conversion functions are now locale aware.
The also now support hexadecimal floating point notation.
Add the wcsto{floating point} conversion functions.
Fix a bug in mktime() related to dst. Note that unlike glibc's mktime,
uClibc's version always normalizes the struct tm before attempting
to determine the correct dst setting if tm_isdst == -1 on entry.
Add a stub version of the libintl functions. (untested)
Fixed a known memory leak in setlocale() related to the collation data.
Add lots of new config options (which Erik agreed to sort out :-),
including finally exposing some of the stripped down stdio configs.
Be careful with those though, as they haven't been tested in a
long time.
(temporary) GOTCHAs...
The ctype functions are currently incorrect for 8-bit locales. They
will be fixed shortly.
The ctype functions are now table-based, resulting in larger staticly
linked binaries. I'll be adding an option to use the old approach
in the stub locale configuration.

I've tried several times to compile uClibc with soft-float
(both gcc-3.2.2 toolchain and wrapper), but applications
compiled with uClibc always failed with "Invalid instruction".
So I ended up disabling floating point at all and this works well.
I also has no problem with glibc from Monta Vista, which is
compiled with soft-float. My processor is PowerPC 405GP.
Maybe the problem is in FP() macro definition in
libc/sysdeps/linux/powerpc/setjmp.S and
libc/sysdeps/linux/powerpc/__longjmp.S
#ifdef __UCLIBC_HAS_FLOATS__
#define FP(x...) x
#else
#define FP(x...)
#endif
which should be defined as
if defined __UCLIBC_HAS_FLOATS__ && ! defined __UCLIBC_HAS_SOFT_FLOAT__
#define FP(x...) x
#else
#define FP(x...)
#endif

After removal of stropts.h none of the files references bits/stropts.h, so

are trashable :-)

On the H8 varargs are rather unusual and if you declare a function with
varargs, it had better use them or it won't work.
