* ARM: Allow building __longjmp as Thumb.Will Newton2013-10-041-3/+3
| | | | | | | | | | | | | Convert __longjmp code to allow building as Thumb. ports/ChangeLog.arm: 2013-10-04 Will Newton <will.newton@linaro.org> * sysdeps/arm/__longjmp.S (NO_THUMB): Remove define. (__longjmp): Use Thumb supported instructions. * sysdeps/unix/sysv/linux/arm/____longjmp_chk.S (NO_THUMB): Remove define.
* ARM: Add pointer encryption support.Will Newton2013-10-031-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* arm: Delete LOADREGS macroRichard Henderson2013-03-061-1/+1
| | | | | | There was only one user. It's "condition" argument was used for "ia" rather than an actual condition. The apcs26 syntax is almost certainly not needed, given current binutils requirements.
* arm: Mark assembly files that will not use thumb modeRichard Henderson2013-02-281-0/+2
| | | | | | | | | Some routines are written with complex LDM/STM insns that cannot be used in thumb mode, or are highly conditional requiring excessive IT insns. When a future patch goes in to enable thumb2 by default, this marker will be used to override that default.
