2004-12-11Partial commit of a patch from Alexandre Oliva:Eric Andersen
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,

2004-11-17Make __builtin_return_address() return NULL at top ofJoakim Tjernlund
stack frame. This will make backtracing possible.

enabled. syslog() support should now work both inside and outside of chroots. erandom code left in but remains #ifdef out by default. May remove erandom completely in the future for uClibc unless the LFS guys and gals want to keep it.

2004-11-02struct ipc_perm, as used by shmctl() when soing shared memory stuff,Eric Andersen
was incorrect in uClibc, and was 2 bytes too short. This caused uClibc shared memory stuff to not behave correctly since struct ipc_perm was included as the first member of, i.e. struct msqid_ds, so the content of that struct were all shifted by two bytes. ugh. Apparently, few people have used shared memory, msgctl(), etc with uClibc thus far, -Erik
2004-10-31Revert Peter's __lib_gettimeofday patch. There's the minor issue ofManuel Novoa III
adding cruft to include/sys/time.h. But also, there's no sense in making changes like this until we decide how we're going to approach the hidden symbol transition.

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)

Hi. I found a mismatch between uClibc and kernel in semctl definition. In uClibc/libc/misc/sysvipc/sem.c: static inline _syscall4(int, __semctl, int, semid, int, semnum, int, cmd, union semun *, arg); ... int semctl(int semid, int semnum, int cmd, ...) ... arg = va_arg (ap, union semun); ... return __semctl(semid, semnum, cmd, &arg); But kernel's semctl is: asmlinkage long sys_semctl (int semid, int semnum, int cmd, union semun arg) The last argument is an union semun itself, not a pointer to the union. Here is a patch.

2004-09-02Add a couple of mips-specific string funcs.Manuel Novoa III
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.

- adjust licensing terms of sources for crt*.o - change the stat ABI to speed it up, matching changes in the kernel - assorted bug-fixes, improvements and updates in the FR-V port etc.

this was sent earlier in a different form: http://www.uclibc.org/lists/uclibc/2004-January/008136.html find attached a smaller version ... perhaps adding a fprintf to stderr before calling abort would be nice like in the glibc patch, but whatever glibc has since adopted a similar fix for their malloc (third hunk, line 1970) http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/malloc/malloc.c.diff?r1=1.121&r2=1.122&cvsroot=glibc&f=h -mike

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
2004-08-25Patch by Carl SHAW <carl.shaw@st.com>...Manuel Novoa III
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...

2004-08-21Attempt to support 'gcc -finstrument-functions', which seems muchEric Andersen
more sane than 'gcc -pg' and seems much easier to support. -Erik
2004-08-21Kill off all support for 'gcc -pg' / 'gprof' style profiling. There is both aEric Andersen
size and performance penalty to profiling applications this way, as well as Heisenberg effects, where the act of measuring changes what is measured. There are better tools for doing profiling, such as OProfile, that do not require gcc to instrument the application code. -Erik
