* sysdeps/powerpc/powerpc32/fpu/fprsave.S: Add cfi_offset for spilling
of non-volatile floating-point registers to the stack (fp14-fp31). * sysdeps/powerpc/powerpc32/gprsave0.S: Add cfi_offset for spilling of non-volatile general-purpose registers to the stack (gpr13-gpr31). * sysdeps/powerpc/powerpc64/dl-trampoline.S: Add cfi_offset for non-volatiles gpr30 - grp31 spilled to the stack. * sysdeps/powerpc/powerpc64/memcpy.S: Add cfi_offset for non-volatile gpr31 spill to the stack. * sysdeps/unix/sysv/linux/powerpc/powerpc32/setcontext-common.S: Add cfi_offset for non-volatile gpr31 spill to the stack. * sysdeps/unix/sysv/linux/powerpc/powerpc64/clone.S: Add cfi_offset for non-volatiles gpr28 - grp31 spilled to the stack. * sysdeps/unix/sysv/linux/powerpc/powerpc64/getcontext.S: Add cfi_adjust_cfa_offset when a frame is stacked. * sysdeps/unix/sysv/linux/powerpc/powerpc64/setcontext.S: (__novec_setcontext) : Add cfi_offset for non-volatile gpr31 spill add LR saved to the stack. Add cfi_adjust_cfa_offset when frame is stacked. (__setcontext) : Add cfi_offset for non-volatile gpr31 spill to the stack. * sysdeps/unix/sysv/linux/powerpc/powerpc64/swapcontext.S: (__novec_swapcontext) : Add cfi_offset for non-volatile gpr31 spill add LR saved to the stack. (__swapcontext) : Add cfi_offset for non-volatile gpr31 spill add LR saved to the stack. Add cfi_adjust_cfa_offset when frame is stacked.
