--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I thought these days most of the time signal frames work through glibc using
the right unwind info for the trampolines.
sysdeps/unix/sysv/linux/x86_64/libc_sigaction.c on x86_64 etc.
MD_FALLBACK_FRAME_STATE_FOR just kicks in when that isn't provided.
