2016-03-31arm: simplify handling of Thumb related optionsThomas Petazzoni
Currently, the Thumb support on ARM has three related Config.in options, which are not trivial for users to understand, and are in fact not needed: - The USE_BX option is not needed: knowing whether BX is available or not is easy. If you have an ARM > v4 or ARMv4T, then BX is available, otherwise it's not. This is the logic used in glibc. - The USE_LDREXSTREX option is not needed: whenever Thumb2 is available, ldrex/strex are available, so we can simply rely on __thumb2__ to determine whether ldrex/strex should be used, without requiring a Config.in option. - Once USE_BX and USE_LDREXSTREX are removed, the only thing left that COMPILE_IN_THUMB does is to set -mthumb. This makes the option unnecessary, as on ARM at least, the user is already supposed to pass -march=<foo> or other compiler options tuning the library for a specific ARM variant. There is no reason to do otherwise for Thumb, which allows to get rid of the COMPILE_IN_THUMB option. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

No real hardware available. The project for sh64 with sh5 seems dead since 10 years. Gcc will remove support for it soon.

It's even no longer required for non-ported ppc64 architecture. Sync with GNU C library. This simplify the macros in include/libc-symbols.h.

2015-10-08xtensa: support call0 ABIMax Filippov
Most changes are mechanical replacement of 'retw' instruction with 'abi_ret' macro, defined to 'retw' or 'ret' according to ABI. Assembly code that makes calls is duplicated for call0 ABI with changed register numbers for parameters/return value and call instruction. 'entry' instructions are replaced with 'abi_entry' macro. More interesting changes: - non-leaf assembly functions (e.g. _dl_tlsdesc_dynamic, _dl_linux_resolve, SYSCALL_ERROR_HANDLER, PSEUDO) now need to preserve registers around intermediate calls they make, use temporary stack frame for that; - setjmp/longjmp only need to save and restore return address, stack pointer and callee-saved registers in the jmpbuf; - __clone and syscall functions had hardcoded offsets to parameter passed on stack, on call0 ABI they don't need stack frame, so the offset is different. Replace these offsets with FRAMESIZE macro. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
2015-09-15NPTL: fix CFLAGS for cancellation pointsMax Filippov
Stack unwinding that happens during NPTL thread cancellation needs cancellable syscall wrapper functions to be compiled with -fexceptions -fasynchronous-unwind-tables to be able to unwind to cleanup handlers registered before syscall invocation. Add these flags for all cancellable syscall wrappers. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
2015-08-27nptl_db/db_info: fix the incorrect initial size for dtvpJunling Zheng
When debugging a program on ARMv7 with thread-local storage declared using "__thread", attempting to print a thread-local variable will result in the following message: Cannot find thread-local storage for Thread <snip> (LWP <snip>), executable file /tmp/tls: capability not available This can be traced back to uclibc libpthread/nptl_db/td_thr_tls_get_addr.c which gdb uses to look up the address of the TLS. The function returns TD_NOCAPAB due to a mismatch in size between the DTV pointer and the size recorded in the db description. The problem lies in libpthread/nptl_db/db_info.c which initializes the db with the sizeof the union dtv. Instead it should be the sizeof a pointer to union dtv. Fixed the initial size for dtvp to sizeof a pointer, instead of sizeof the union.

2015-06-30NPTL/arc: notify kernel of the TP valueVineet Gupta
Native gdb makes a ptrace (GET_THREAD_AREA) which needs to return the TP. however when libc sets up TP reg (for main thread), it doesn't call arc_settls syscall so kernel doesn't know of TP register details (moreso because clone doesnt have SETTLS flag) Note that kernel doesn't know about r25 being TP etc. This commit got lost in merge of NPTL tools into arc-mainline-dev and showed up again as STAR 9000919529 (native gdb can't debug threaded apps) ------->8--------------- [ARCLinux]# gdb ./pth Reading symbols from ./pth...(no debugging symbols found)...done.

2014-12-15mkostemp: fix implementationAnthony G. Basile
mkostemp(char *template, int flags) generates a unique temporary filename from a template. The flags parameter accepts three of the same flags as open(2): O_APPEND, O_CLOEXEC, and O_SYNC. The current implementation of mkostemp(3) does not respect the flags and in fact confuses the flags with the file mode which should always be S_IRUSR | S_IWUSR. This patch corrects this issue.
