Does sysdeps/unix/sysv/linux/arm/eabi/sigrestorer.S need any treatment?
It's probably not worth it.


In sysdeps/unix/sysv/linux/arm/eabi/sysdep.h:INTERNAL_SYSCALL_RAW for
[__thumb__], should we, depending on defined (__GCC_HAVE_DWARF2_CFI_ASM),
emit CFI statements to handle r7's modification and restoral?  We can't
emit CFI statements unconditionally, as it's GCC's decision whether to
emit .cfi_startproc or not, and in the latter case we're not allowed to
using them in inline assembly.

This thread now contains all I have done.
