* This change reimplements the ARM _dl_linux_resolve entry point - this isEric Andersen2006-11-103-53/+192
| | | | | | | called to resolve DLL PLT entries. The assembler is changed to be thumb compatible and slightly faster, the C function, _dl_linux_resolver (note the extra r) is changed to take a byte address in place of an 8 byte count (faster in caller and callee, and slightly easier to understand).
* arm thumb:Eric Andersen2006-11-103-19/+131
| | | | | | | | | | | | | | | | | | | | | | Put the call_via_rx code into each executable - call_via_ip cannot possibly work if called through the PLT! ldso requires this code too as it is not linked with the crt stuff and thumb ldso does make calls via a register. The patch puts the code into crti.S so that it is linked into every normally built application (if thumb or interworking is selected). This is only 30 extra bytes and it works - the previous code did not because nothing both implemented and exported the APIs (they were in libgcc, but not in the version script). crti.S and crtn.S is also brought up to date with GCC 3.4.4 - this is essential for thumb support because the .init and .fini sections must use arm or thumb code to match the compilation of the libraries. Note that code which pushes stuff into .init or .fini must be compiled with or without -mthumb to match the uclibc compilation - and gcc itself (which does do this) must therefore be compiled to match.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2001-04-10 Ulrich Drepper <drepper@redhat.com> * join.c (pthread_exit): Move code to new function __pthread_do_exit which takes an extra parameter with the current frame pointer. Call new function with CURRENT_STACK_FRAME. (__pthread_do_exit): New function. Call __pthread_perform_cleanup with the new parameter. (pthread_join): Call __pthread_do_exit instead of pthread_exit. * cancel.c (__pthread_perform_cleanup): Takes extra parameter. Use this parameter as the initial value the cleanup handler records are compared against. No active cleanup handler record must have an address lower than the previous one and the initial record must be above (below on PA) the frame address passed in. (pthread_setcancelstate): Call __pthread_do_exit instead of pthread_exit. (pthread_setcanceltype): Likewise. (pthread_testcancel): Likewise. (_pthread_cleanup_pop_restore): Likewise. * condvar.c (pthread_cond_wait): Likewise. (pthread_cond_timedwait_relative): Likewise. * manager.c (pthread_start_thread): Likewise. * oldsemaphore.c (__old_sem_wait): Likewise. * pthread.c (pthread_handle_sigcancel): Likewise. * semaphore.c (__new_sem_wait): Likewise. (sem_timedwait): Likewise. * ptlongjmp.c (pthread_cleanup_upto): Also use current stack frame to limit the cleanup handlers which get run. * internals.h: Add prototype for __pthread_do_exit. Adjust prototype for __pthread_perform_cleanup.

* mips64 patch from Atsushi Nemoto:Eric Andersen2006-11-061-1/+1
| | | | | | | We should not use old stype ipc_perm for 64-bit mips kernel. I suppose other 64-bit platforms shoule define __IPC_64 also and we can define it unconditionally, but not sure for other archs ...

| | | | | The mips64 N32/N64 ABI have a bit different register usage convention. Also the register size for these ABI is 8 byte. Use ld/sd for them.

* mips64 patch from Atsushi Nemoto:Eric Andersen2006-11-041-0/+38
| | | | | It seems these codes dropped when importing from glibc. This is required for mips64.

| | | | | | | There is a mismatch of struct msghdr between the kernel and libc. In a 64-bit environment, the size of msg_namelen is 4 for all, but the size of msg_iovlen and msg_controllen is 8 bytes for the kernel and for glibc, but 4 bytes for uClibc. Fix size for the 64bit case.

| | | | | | | | In 2005, Congress passed a law so that in 2007, the second week of March starts DST. Previously, it was the first week of April. The uclibc time library routines apparently have not been updated to reflect this new processing. Using the current version of uclibc, on March 11, 2007 the reported time will be incorrect.

| | | | | | There are many directories called "CVS" checked into uClibc SVN, probably as a side-effect of importing a CVS checkout. I don't think these are particularly useful to have checked in.
* Make strdup() use memcpy() rather than strcpy() to duplicate the string. Peter Kjellerstedt2006-10-191-6/+4
| | | | | | The rationale is that we already have the length of the string to duplicate (from doing the malloc()), and memcpy() should then always be faster than strcpy() (or at least as fast).

| | | | | | | | | | | This introduces a new SEND_EARLY_STDERR macro that is to be used in dl-startup.c before ld.so is relocated. It is needed on Blackfin (and frv) FDPIC since we have to use special tricks to get the address of a string constant. EARLY_STDERR_SPECIAL gets defined on such a machine and prevents printing of debug strings inside the loop that relocates ld.so, since we can't decide which of the two variants to use.
