I agree it probably won't make a difference at runtime but I don't think the
assembler should be at liberty to make instructions conditional when they
weren't in the first place.
Moreover, I notice that:
LDCEQ.W p6 , c3 , [ r2 ] , { 33 }
NOPAL.W
still results in:
0: bf04 itt eq
2: ec92 3621 ldceq 6, cr3, [r2], {33} ; 0x21
6: f3af 8000 nopeq.w
Also a straight:
NOPCC.W
results in:
0: f3af 8000 nop.w
So bottomline, it looks like the condition code of a nop gets ignored.
