* Partial commit of a patch from Alexandre Oliva:Eric Andersen2004-12-111-0/+5
| | | | | | | | | | Here's an updated version of the patch I posted about a month ago. It leaves -nostdinc alone, and uses -print-file-name=include instead of -print-search-dirs to figure out where GCC's internal headers are. Please let me know whether there are any portions of this patch you'd like me to break into smaller pieces, to rework, or to give up trying to get into uClibc :-) Thanks,

| | | | | | | | | | | | | | | | After the addition of a configuration option for enabling the support of /etc/ld.so.cache, I thought it might be a good idea to add one for the support of the /etc/ld.so.preload file too. So here it is. While doing this, I also noticed that the dynamic linker would hang indefinitely if either LD_PRELOAD or /etc/ld.so.preload contained a library which was already loaded, so I made a patch for that too. And of course, I could not resist from doing a little clean up of comments and indentation, so here is a patch for that too.

* Add a couple of mips-specific string funcs.Manuel Novoa III2004-09-021-0/+20
| | | | | | | | | Port the generic optimized string funcs from glibc, with some tweaks to cut their size a little. The main change is making memmove call memcpy for forward copying to trim redundant code. Make use of both the generic and arch-specific speed-optimized string funcs configurable. Arch-specific take precedence over generic, and generic takes precedence over basic size-optimized uClibc funcs.

| | | | | | | | | | | | | 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. Pete

* Alexandre Oliva writes:Eric Andersen2004-02-183-0/+179
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | 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
* Rework malloc. The new default implementation is based on dlmalloc from DougEric Andersen2003-12-301-8/+20
| | | | | | | 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
* Patch from Paul Mundt <lethal@linux-sh.org>:Eric Andersen2003-12-171-1/+0
| | | | | | | | | | 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.
* Paul Mundt <lethal@linux-sh.org> writes:Eric Andersen2003-12-051-1/+0
| | | | | | | | | | | | | 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.
* Set the default stdio buffer size to 4096, rather then 256.Eric Andersen2003-12-041-1/+1
| | | | | 256 is fine of course, but many applications use this value and expect it to be larger.
* Paul Mundt <lethal@linux-sh.org> writes:Eric Andersen2003-12-031-4/+4
| | | | | | 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.
