Do we know that the blank will be filled with something harmless ?
Yes. See ppc_handle_align() in gas/config/tc-ppc.c : it fills with nops
(ori 0,0,0), and a branch if there are more than four nops, and for
POWER6
and POWER7 it puts a group-terminating insn (ori 1,1,0 resp. ori 2,2,0)
at
the end.
It has done this (well, nops at least) since 2001.
