--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
IMHO the nops should go immediately before the first real instruction in the
function. The point of not emitting it earlier is so that the nops are already
covered by debug and unwind info.
So, we certainly should skip all NOTEs at the start of the function, and
perhaps
selected other insns (dunno if e.g. UNSPECV_MAIN_POOL insn emits any code or
not). NOTE_INSN_FUNCTION_BEG is not a good place, as it can be preceeded by
various prologue instructions, and the nops really have to go before all real
instructions (that emit some bytes into the function text section).
