Hi Erik It seems to me that __pthread_once and __pthread_initialize_minimal could be made WEAKs with no stub. The code in rpc_thread.c and __uClibc_main.c appears to expect this. Also, __pthread_return_0 __pthread_return_1 and __pthread_return_void can be static, not to pollute the name space. Jocke

Here are a number of minor changes to FR-V-specific bits of the uClibc port: - I've adjusted the definition of _dl_mmap to cope with the fact that there will be a definition for an mmap2-only system. - We don't have COPY relocs, so optimize the copy reloc-related code away. - Change the page size to 16KiB, to match the ABI spec, and not a stale value I'd copied from a linker config file. Oops. - Fix error handling in clone and vfork; parts of the changes by David Howells <dhowells@redhat.com> - Rearrange includes in crtreloc.c. - Change the API of __syscall_error, to reduce code size. - Improve __syscall_return in terms of code size, so as to enable tail-calling of __syscall_error, at least within libc. Ideally, __syscall_error should be hidden within libc.so, but this didn't work because of libdl. I haven't looked into why, and figured I'd leave it visible for now. - Rename enumerators and macros in sys/ucontext.h to reduce namespace pollution.
2004-05-14__data_start needs to be added to all crt0.S files that don't currentlyEric Andersen
have it. It is used by the boehm gc, amoung other things.

2004-05-08Obligatory forgotten file...Manuel Novoa III
2004-05-08Change clock() to allow wrapping.Manuel Novoa III
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.
2004-05-07Patch from Yoshinori Sato <ysato@users.sourceforge.jp>.Manuel Novoa III
2004-05-07"Fix" this so that at least things will link when threading is disabled.Manuel Novoa III
Also fix the sizeof() issue since the change to a dynamicly allocated buf. Note! This is still broken wrt threading, but so is the glibc version. I'm just commiting this for new until I can test my rewrite.
2004-05-07Fix a couple of issues in configurations I hadn't tested.Manuel Novoa III
2004-05-07Add missing include.Manuel Novoa III
2004-05-07Change the global 'buf' to 'servbuf' since some functions in here useEric Andersen
a local named 'buf' and we want to avoid shadowing that.
2004-05-05Fix screwed up formattingEric Andersen
2004-05-05Jeroen Dobbelaere writes:Eric Andersen
Because variables are linked to fixed registers, there is a problem in : (*__errno_location())=(-_r0); As __errno_location() uses r0 to return the address of the errno location, the negated address will be assigned instead of the error code. Attached patch will resolve this.
2004-04-23It turns out that asm/reg.h is missing from the 2.6.x kernel headers,Eric Andersen
which prevents libthread_db (used by gdb) from compiling. Include a copy within include/sys/user.h for mips, per what was done in glibc.
2004-04-20Cope with gcc 3.4's more aggressive persuit of attribute unusedEric Andersen
2004-04-14Fix typo.Manuel Novoa III
2004-04-06Fix a bug noticed by Oleg I. Vdovikin, oleg at cs dot msu dot su.Eric Andersen
This code in uClibc would attempt to set the default facility if none was specified. Except none being specified is 0, which is also LOG_KERN, therefore klogd could never get kernel messages logged as LOG_KERN.

I added this function after I posted the last version of the FR-V patch. Add syscall.c.
2004-03-18Supply '__bzero' with 'bzero' as just a weak alias (since it is not SuSv3)Eric Andersen
2004-03-18Based on a patch from Alexandre Oliva, remove all reference to 'bzero' (whichEric Andersen
is not a SuSv3 symbol). Rather than using __bzero internally per Alexandre's original patch, use memset instead.
2004-03-18Reduce memory used by static buffers and allocate that memory dynamiclyEric Andersen
instead. Based on an initial patch from Tobias Anderberg, but reworked. I asked Tobias to look into doing something more like what is done in busybox, but that proved to be a pain. One possible concern is that these buffers will probably show up as memory leaks i.e. with valgrind. Perhaps we should add in an atexit call to free this memory right after we allocate it?
2004-03-12Cope gracefully with missing module syscallsEric Andersen
2004-03-11Rewrite the err/warn functions as they were broken (__noreturn__ funcsManuel Novoa III
were returning). Anyway, also make them threadsafe and smaller. The error.c file still needs work.
2004-03-10Bug fix: gethostbyname2_r would fail if /etc/host was missing.Manuel Novoa III
Bug fix: gethostbyname_r checked errno without first setting it to a known value.
2004-02-18Fixup naming of '_mmap' to 'mmap' so it will properly overrideEric Andersen
the symbol in common.

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.

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.
