- Subject: unexpected NOP encodings
All,
is it known (and intended) that
.text
.machine power8
power8:
nop
# The NOP inserted here is controlled by the "power6" machine
# setting below, not the one currently in effect.
.p2align 3
blr
.machine power6
doesn't produce the expected NOP encoding, because the encoding is
chosen only at the end of the assembly process (i.e. when the final
directive has already been seen and processed)?
