* AArch64: use movz/movk instead of literal pools in start.SWang Boshi2017-09-181-0/+14
| | | | | | | | | | | | | | | eXecute-Only Memory (XOM) is a protection mechanism against some ROP attacks. XOM sets the code as executable and unreadable, so the access to any data, like literal pools, in the code section causes the fault with XOM. The compiler can disable literal pools for C source files, but not for assembly files, so I use movz/movk instead of literal pools in start.S for XOM. I add MOVL macro with movz/movk instructions like movl pseudo-instruction in armasm, and use the macro instead of literal pools. * sysdeps/aarch64/start.S: Use MOVL instead of literal pools. * sysdeps/aarch64/sysdep.h (MOVL): Add MOVL macro.

* [AArch64] Fix libc internal asm profiling codeSzabolcs Nagy2016-07-111-2/+31
| | | | | | | | | | | | | | | | | | | | | When glibc is built with --enable-profile, the ENTRY of asm functions includes CALL_MCOUNT for profiling. (matters for binaries static linked against libc_p.a.) CALL_MCOUNT did not save/restore argument registers around the _mcount call so it clobbered them. (it is enough to only save/restore the arguments passed to a given asm function, but that would be too many asm changes so it is simpler to always save all argument registers in this macro.) float args are not saved: mcount does not clobber the float regs and currently no asm function takes float arguments anyway. [BZ #18707] * sysdeps/aarch64/Makefile (CFLAGS-mcount.c): Add -mgeneral-regs-only. * sysdeps/aarch64/sysdep.h (CALL_MCOUNT): Save argument registers.

* Relocate AArch64 from ports to libc.Marcus Shawcroft2014-02-111-0/+98
This patch moves the AArch64 port to the main sysdeps hierarchy. The move is essentially: git mv ports/sysdeps/aarch64 sysdeps/aarch64 git mv ports/sysdeps/unix/sysv/linux/aarch64 sysdeps/unix/sysv/linux/aarch64 The README is updated and I've updated ChangeLog.aarch64 along the lines of the ARM move. The AArch64 build has been tested to confirm that there were no changes in objdump -dr output or the shared objects.
