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.

2004-02-17Sigh... Fall back to alloca() if munmap is broken (uClinux).Manuel Novoa III
2004-02-15Generic fork works. Use it instead since this didn't handle errno_location.Manuel Novoa III
2004-02-15Oops.Eric Andersen

2004-02-13Oops.. The custom stream funcs should only be compiled if wanted.Manuel Novoa III

We can't use trapa #0xff on sh2, the only permissible trapa ranges are 32 to 63. On SH-2, we use trapa32 to issue a break in the same way that trapa #0xff is used on SH-3/4. This behavior is implementation specific, but is what is used in sh-ipl+g, linux, eCos, uITRON, etc. so we follow suit here.
2004-02-12Add missing mips specific include/sys/user.hEric Andersen
2004-02-11New stdio core. Should be more maintainable. Fixes a couple of bugs.Manuel Novoa III
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.
2004-02-11Fix bug from the syscall reorganization, detected by python's test_poll.py.Manuel Novoa III
The #ifdef __NR_poll test was failing because it was done before any includes. Hence, the emulation was always being used. NOTE: The emulation fails a couple of tests in test_poll.py!
2004-02-10Do not include the create_module syscall if it is not presentEric Andersen
2004-02-06Fix completely hosed up formattingEric Andersen
2004-02-06Sigh. The 2.6.x kernel removed '__kernel_dev_t' and renamed it asEric Andersen
'__kernel_old_dev_t'. And of course there is no good way to know which is in use except checking linux/version.h. Grumble. This is rather lame, but for now, define __kernel_old_dev_t to be the same as __kernel_dev_t. This will want to be revisited soon. -Erik

Here are some simple fixes for things that broke for PPC with the recent syscall cleanup. I am not sure they are correct but they seem pretty trivial.

Hi Erik I have had some fun trying to optimize memcpy, memset and memmove for PPC. There are only boot tested, but I don't expect any problems :) Read the comments in powerpc/string.c for more info. Patch is relative to libc/string Jocke

Hi Erik I have corrected a bug in uClibc/libc/inet/resolv.c in function __dns_lookup(). Have attaced a txt file with my diffs regarding to uClibc 0.9.26. If two nameservers are included in /etc/resolv.conf and the first one is wrong and the secondary is correct the algorithm never looked up the secondary one. Please review my diff and feel free to submit the patch onto your CVS. If reading manual page resolv.conf(5) under nameserver and how the algorithm should work the previous dns_lookup did not fully followed that. Regards Imre Sunyi

2004-01-14Ok.. we need to link with libgcc.a for some archs. I haven't looked atManuel Novoa III
all cases, but the archs I've looked at do build the needed routines as PIC so we should be ok.
2004-01-14Add a dummy (always fails) wcsftime. This is needed for the libstdc++ localeManuel Novoa III
implementation to build. Later this month I'll add a functional wcsftime.

2004-01-12Oops... Seems I forgot an else...Manuel Novoa III
2004-01-04Implement res_search and res_querydomain based on netbsd code,Eric Andersen
but remove support for host aliases (the HOSTALIASES env variable) which looks like a very bad idea. -Erik
2004-01-04My mistake. We do need some weak pthread_* funcs. But we were previouslyManuel Novoa III
missing one in the glibc abi, and including a number of extras (which I left in commented). Unfortunately, this brings back the perl pthread bug. Fixing the incorrect weaks in libpthread wasn't sufficient to escape the shared loader bug. :-(
2004-01-03And just like that, clone is now fixed.... Previously theEric Andersen
error handling code was mostly broken. -Erik

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

The macro to do some floating point checks in libc/sysdeps/linux/powerpc/setjmp.S is incorrect. The following should fix it. Same applies to uClibc/libc/sysdeps/linux/powerpc/__longjmp.S Hope there aren't other files I've missed :)
