Hi Bernd, in a way,yes.I am testing it.Since I don't have a FSF copyright mark,and I have no idea what is that file saying,I can't commit my patch.If you are interested in it,please help me commit it.
By the way,there is another way to work it out,and it has been mentioned in the previous(I don't know how previous) mail.That is to use unaligned instructions instead of aligned ones on the armv7 or above platform.That has to modify part of machine desc of arm platform.I can't tell you it's one of the define_peephole.I have no time to test this idea yet.If you are interested in that way,please test this one.It's always better when there is an option. -- Regards lin zuojian
