--- Comment #5 from Mikael Pettersson <mikpelinux at gmail dot com> ---
I can't reproduce on {ppc64le, ppc64, aarch64, m68k, x86_64}-linux-gnu, they
all inline the dispatcher at the end of each handler, w/ gcc-10.2.0 -O2. 
However, for sparc64 gcc-10.2.0 -O2 does end each handler with a branch to a
shared dispatcher (which is not what we want).
