13 years agoReplace the old algorithm that emitted the "print the alias for an instruction"
Bill Wendling [Thu, 7 Apr 2011 21:20:06 +0000 (21:20 +0000)]
Replace the old algorithm that emitted the "print the alias for an instruction"
with the newer, cleaner model. It uses the IAPrinter class to hold the
information that is needed to match an instruction with its alias. This also
takes into account the available features of the platform.

There is one bit of ugliness. The way the logic determines if a pattern is
unique is O(N**2), which is gross. But in reality, the number of items it's
checking against isn't large. So while it's N**2, it shouldn't be a massive time
sink.

A8.6.92 MCR (Encoding A1): if coproc == '101x' then SEE "Advanced SIMD and VFP"
Since these "Advanced SIMD and VFP" instructions have more specfic encoding bits
specified, if coproc == 10 or 11, we should reject the insn as invalid.
