2014-04-30Move ports/ChangeLog* files to ChangeLog.old-ports*, remove ports/ directory.Roland McGrath
2014-02-08Move arm from ports to libc.Joseph Myers
I've moved the ARM port from ports to the main sysdeps hierarchy. Beyond the README update, the move of the files was simply git mv ports/sysdeps/arm sysdeps/arm git mv ports/sysdeps/unix/arm sysdeps/unix/arm git mv ports/sysdeps/unix/sysv/linux/arm sysdeps/unix/sysv/linux/arm and in addition to the ChangeLog entries here, I put a note at the top of ports/ChangeLog.arm similar to that at the top of ChangeLog.powerpc. There is deliberately no NEWS change, as I think it makes the most sense to put in a general note above all ports having moved if we can achieve that for 2.20. Tested that disassembly of installed shared libraries for arm is the same before and after this patch, except for data (not instructions) in ld.so (there are assertions in sysdeps/arm/dl-machine.h, and the path by which that file is found, and so by which it appears in the assertion message, changes as a result of the move). * sysdeps/arm: Move directory from ports/sysdeps/arm. * sysdeps/unix/arm: Move directory from ports/sysdeps/unix/arm. * sysdeps/unix/sysv/linux/arm: Move directory from ports/sysdeps/unix/sysv/linux/arm. * README: Update listing for arm-*-linux-gnueabi. ports/ChangeLog.arm: * sysdeps/arm: Move directory to ../sysdeps/arm. * sysdeps/unix/arm: Move directory to ../sysdeps.arm. * sysdeps/unix/sysv/linux/arm: Move directory to ../sysdeps/unix/sysv/linux/arm.
2014-02-08Move shared sysdeps files from alpha to arm.Joseph Myers
This patch prepares for moving arm from ports to libc (see overall plan at <https://sourceware.org/ml/libc-alpha/2014-01/msg00373.html> and discussion of ordering starting at <https://sourceware.org/ml/libc-ports/2014-01/msg00071.html>) by reversing the #include order between arm and alpha, so that arm can move early as a test for the general pattern of moving architectures. MicroBlaze files (that used the same alpha files) were made to include the files directly from their new locations rather than indirecting. Tested that disassembly of installed shared libraries for arm is the same before and after this patch. * sysdeps/unix/sysv/linux/alpha/msgctl.c: Move to sysdeps/unix/sysv/linux/arm/msgctl.c and #include that file. * sysdeps/unix/sysv/linux/alpha/semctl.c: Move to sysdeps/unix/sysv/linux/arm/semctl.c and #include that file. * sysdeps/unix/sysv/linux/alpha/shmctl.c: Move to sysdeps/unix/sysv/linux/arm/shmctl.c and #include that file. * sysdeps/unix/sysv/linux/arm/msgctl.c: Move from sysdeps/unix/sysv/linux/alpha/msgctl.c instead of #include of that file. * sysdeps/unix/sysv/linux/arm/semctl.c: Move from sysdeps/unix/sysv/linux/alpha/semctl.c instead of #include of that file. * sysdeps/unix/sysv/linux/arm/shmctl.c: Move from sysdeps/unix/sysv/linux/alpha/shmctl.c instead of #include of that file. * sysdeps/unix/sysv/linux/microblaze/msgctl.c: Include sysdeps/unix/sysv/linux/arm/msgctl.c instead of sysdeps/unix/sysv/linux/alpha/msgctl.c. * sysdeps/unix/sysv/linux/microblaze/semctl.c: Include sysdeps/unix/sysv/linux/arm/semctl.c instead of sysdeps/unix/sysv/linux/alpha/semctl.c. * sysdeps/unix/sysv/linux/microblaze/shmctl.c: Include sysdeps/unix/sysv/linux/arm/shmctl.c instead of sysdeps/unix/sysv/linux/alpha/shmctl.c.
2014-01-24ARM: Fix clone build for ARMv4Will Newton
ARMv4 does not have the blx instruction, so use the BLX macro which handles abstracting this for us. Build tested for armv7, armv4t and armv4. ports/ChangeLog.arm: 2014-01-24 Will Newton <will.newton@linaro.org> [BZ #16499] * sysdeps/unix/sysv/linux/arm/clone.S: Use BLX macro instead of blx instruction directly.
2014-01-14ARM: Don't apply pointer encryption to the frame pointerWill Newton
The frame pointer register is rarely used for that purpose on ARM and applications that look at the contents of the jmp_buf may be relying on reading an unencrypted value. For example, Ruby uses the contents of jmp_buf to find the root set for garbage collection so relies on this pointer value being unencrypted. Without this patch the Ruby testsuite fails with a segmentation fault. ports/ChangeLog.arm: 2013-01-14 Will Newton <will.newton@linaro.org> * sysdeps/arm/__longjmp.S: Don't apply pointer encryption to fp register. * sysdeps/arm/setjmp.S: Likewise. * sysdeps/arm/include/bits/setjmp.h (JMP_BUF_REGLIST): Add fp to register list, remove a4. * sysdeps/unix/sysv/linux/arm/sysdep.h (PTR_MANGLE_LOAD): New macro.

2013-10-04ARM: Allow building __sigsetjmp as Thumb.Will Newton
Convert __sigsetjmp code to allow building as Thumb. ports/ChangeLog.arm: 2013-10-04 Will Newton <will.newton@linaro.org> * sysdeps/arm/setjmp.S (NO_THUMB): Remove define. (__sigsetjmp): Use Thumb supported instructions.

2013-10-03ARM: Add pointer encryption support.Will Newton
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.

2013-09-16ARM: Improve armv7 memcpy performance.Will Newton
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.

2013-08-30ARM: Fix clone code when built for Thumb.Will Newton
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.
2013-08-30sysdeps/arm/armv6t2/strlen.S: strlen implementation for armv6t2.Will Newton
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.

2013-05-29Avoid crashing in LD_DEBUG when program name is unavailableSiddhesh Poyarekar
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.
