* ARM: Add pointer encryption support.Will Newton2013-10-031-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for pointer encryption in glibc internal structures in C and assembler code. Pointer encryption is a glibc security feature described here: https://sourceware.org/glibc/wiki/PointerEncryption The ARM implementation uses global variables instead of thread pointer relative accesses to get the value of the pointer encryption guard because accessing the thread pointer can be very expensive on older ARM cores. ports/ChangeLog.arm: 2013-10-03 Will Newton <will.newton@linaro.org> * sysdeps/arm/__longjmp.S (__longjmp): Demangle fp, sp and lr when restoring register values. * sysdeps/arm/include/bits/setjmp.h (JMP_BUF_REGLIST): Remove sp and lr from list and replace fp with a4. * sysdeps/arm/jmpbuf-unwind.h (_jmpbuf_sp): New function. (_JMPBUF_UNWINDS_ADJ): Call _jmpbuf_sp. * sysdeps/arm/setjmp.S (__sigsetjmp): Mangle fp, sp and lr before storing register values. * sysdeps/arm/sysdep.h (LDST_GLOBAL): New macro. * sysdeps/unix/sysv/linux/arm/sysdep.h (PTR_MANGLE): New macro. (PTR_DEMANGLE): Likewise. (PTR_MANGLE2): Likewise. (PTR_DEMANGLE2): Likewise.
* ports/sysdeps/arm/nptl/tls.h: Remove TLS_INIT_TP_EXPENSIVE.Will Newton2013-09-241-0/+5
| | | | | | | | | | | This define was removed from the rest of the tree eight years ago. ports/ChangeLog.arm: 2013-09-24 Will Newton <will.newton@linaro.org> * ports/sysdeps/arm/nptl/tls.h (TLS_INIT_TP_EXPENSIVE): Remove macro.
* Make __ffs hiddenAndreas Schwab2013-09-201-0/+4
|
* Improve atomic locking for ARM.Maxim Kuvyrkov2013-09-191-0/+10
| | | | | | | | | | [BZ #15640] * sysdeps/arm/bits/atomic.h (atomic_exchange_acq, atomic_exchange_rel) (atomic_compare_and_exchange_bool_acq) (atomic_compare_and_exchange_val_acq) (atomic_compare_and_exchange_bool_rel) (atomic_compare_and_exchange_val_rel): Use __atomic_exchange_n and __atomic_compare_exchange_n builtins when GCC supports them.
* ARM: Improve armv7 memcpy performance.Will Newton2013-09-161-0/+5
| | | | | | | | | | | | | | Only enter the aligned copy loop with buffers that can be 8-byte aligned. This improves performance slightly on Cortex-A9 and Cortex-A15 cores for large copies with buffers that are 4-byte aligned but not 8-byte aligned. ports/ChangeLog.arm: 2013-09-16 Will Newton <will.newton@linaro.org> * sysdeps/arm/armv7/multiarch/memcpy_impl.S: Tighten check on entry to aligned copy loop to improve performance.
* Use sfi_* macros in armv6t2 strlen.Roland McGrath2013-08-301-0/+2
|

|
* ARM: Fix clone code when built for Thumb.Will Newton2013-08-301-0/+6
| | | | | | | | | | | | | The mov lr, pc instruction will lose the Thumb bit from the return address so use blx lr instead. ports/ChangeLog.arm: 2013-08-30 Will Newton <will.newton@linaro.org> [BZ #15909] * sysdeps/unix/sysv/linux/arm/clone.S (__clone): Use blx instead of mov lr, pc.
* sysdeps/arm/armv6t2/strlen.S: strlen implementation for armv6t2.Will Newton2013-08-301-0/+4
| | | | | | | | | | | This implementation of strlen is faster than the armv6 version for all string lengths greater than 1 on a Cortex-A15. ports/ChangeLog.arm: 2013-08-09 Will Newton <will.newton@linaro.org> * sysdeps/arm/armv6t2/strlen.S: New file.
* Use ELFOSABI_GNU instead of ELFOSABI_LINUX.Thomas Schwinge2013-08-291-0/+6
|

* New API to set default thread attributesSiddhesh Poyarekar2013-06-151-0/+4
| | | | | | | This patch introduces two new convenience functions to set the default thread attributes used for creating threads. This allows a programmer to set the default thread attributes just once in a process and then run pthread_create without additional attributes.
* Update ARM _FPU_RESERVED value.Joseph Myers2013-06-141-0/+6

|
* Avoid crashing in LD_DEBUG when program name is unavailableSiddhesh Poyarekar2013-05-291-0/+7
| | | | | | | | | Resolves: #15465 The program name may be unavailable if the user application tampers with argc and argv[]. Some parts of the dynamic linker caters for this while others don't, so this patch consolidates the check and fallback into a single macro and updates all users.
