Hmm... I found a old fix in uClibc ML archive. http://www.uclibc.org/lists/uclibc/2002-September/004459.html But it seems somewhat broken. How about this fix instead? I tested mmap with syscall() in mips. mips64 is not tested.

| | | | | | | | | | | Hello! Would the attached patch be acceptable (maybe instead of __libc_gettimeofday using __gettimeofday) We have some issues, see http://bugs.gentoo.org/show_bug.cgi?id=65892

| | | | | | | | | In a recent post to linux-mips ML (and libc-alpha ML), a problem with inline syscalls was reported. http://www.linux-mips.org/archives/linux-mips/2004-10/msg00142.html It seems uClibc should be fixed also for newer gcc. Here is a patch.

| | | | | | | | | | | | | | | The attached patch generalizes the use of PIE (all archs are brought in sync that use/mention it: x86/ppc/frv) and makes use of it building the target utils. Tested on x86, ppc should be tested, frv uses -fPIE at one location, but at another place -fpie, I don't know which is correct (could be both) and misses the target addition in Config.in. The test for ppc (requires the earlier sent crt-correction patch to work correctly): enable UCLIBC_PIE_SUPPORT, build uClibc and utils, check: file ./utils/ldd, it should show shared object (instead of executable)

| | | | | | | | | | | | i sent this earlier but perhaps people missed it the first time around :) http://www.uclibc.org/lists/uclibc/2004-August/009544.html basically if you try to #include <sys/ucontext.h> on arm it'll fail because ucontext.h utilizes typedefs found in bits/sigcontext.h ... i386 already has this fix in uClibc find attached a trivial patch to fix this -mike

| | | | | | | | | | | | Below is a patch to make the pread and pwrite calls work on the SH architecture. I've only tested this on the SH4 with a 2.4.24 kernel - a fairly recent kernel is required as the problem is partially fixed in the kernel itself. For more information (in relation to glibc, but the problem is the same) see the thread at http://sourceforge.net/mailarchive/message.php?msg_id=2375908 Someone should really test this on the SH2/3...

| | | | | | | | | | | | | 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

| | | | | | | | | | | | This is a patch for uClibc/libc/sysdeps/linux/mips/sys/procfs.h pulled from glibc CVS. This fixes gdb with threaded application (with glibc environment). Although debugging threaded programs seems not working on uClibc/mips yet, this patch will be required when it becomes working. This patch can be applied to any version of uClibc (including current CVS).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | 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.
