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
2003-12-30Rework malloc. The new default implementation is based on dlmalloc from DougEric Andersen
Lea. It is about 2x faster than the old malloc-930716, and behave itself much better -- it will properly release memory back to the system, and it uses a combination of brk() for small allocations and mmap() for larger allocations. -Erik
2003-12-17Patch from Paul Mundt <lethal@linux-sh.org>:Eric Andersen
Here's the patch for the ldso bits for sh64. This is still in need of a bunch of debugging, testing, etc. and is really only being submitted for general completeness. This assumes that the previous patches I've submitted have already been applied. I plan on playing with this and buildroot some more later, as I'd definitely like to see buildroot images for sh64.

This patch adds the libpthread backend bits for sh64. As noted previously, we can't inline things like the testandset() in pt-machine.h as we need to use a completely different ISA / CFLAGS in order for this to work. As a result, this patch is somewhat of a RFC as well to see what people think of the libpthread/linuxthreads/sysdeps Makefile approach, etc. The approach I've taken currently has been to provide a sysdeps/Makefile with a note that TARGET_ARCHs that want build rules can simply add themselves into the list of matching architectures to add to the subdir rule for. This probably isn't the cleanest solution, but it's quite transparent and works quite well.
2003-12-04Set the default stdio buffer size to 4096, rather then 256.Eric Andersen
256 is fine of course, but many applications use this value and expect it to be larger.

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.

Another little patch fix the configuration for the SH3 targets. The SH3 has no FPU, but our ldso runs fine on a SH3 target. (I think the ldso should also run on a SH2 target, so you might want to enable the ldso for SH2 targets too. But I can't test it, since I have no such a system) :

Dear Erik, We downloded uClibc lattest version from the CVS. Still there are some minor problems with extra/Configs/Config.e1 You have actually set ARCH_HAS_C_SYMBOL_PREFIX to NO which is not correct for our architecture. Please apply the patch that will fix the problem. Best Regards, - George P.S. Patch also removes some irritating comments we have added in the past.

2003-10-31Some more soft float fixes... for arm in particular (libfloat).Manuel Novoa III
Remove the ADD_LIBGCC_FUNCTIONS option and do things the right way. Either we have a shared libgcc available, or the libgcc routines aren't PIC and don't belong in the shared libc anyway.

2003-08-13Patch from Paul Mundt adding uClibc sh64 support:Eric Andersen
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.

2003-08-01Add a new *scanf implementation, includeing the *wscanf functions.Manuel Novoa III
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.
