TableGen has a fairly dubious heuristic to decide whether an alias should be printed: does the alias have lest operands than the real instruction. This is bad enough (particularly with no way to override it), but it should at least be calculated consistently for both strings. This patch implements that logic: first get the *correct* string for the variant, in the same way as the Matcher, without guessing; then count the number of whitespace chars. There are basically 4 changes this brings about after the previous commits; all of these appear to be good, so I have changed the tests: + ARM64: we print "neg X, Y" instead of "sub X, xzr, Y". + ARM64: we skip implicit "uxtx" and "uxtw" modifiers. + Sparc: we print "mov A, B" instead of "or %g0, A, B". + Sparc: we print "fcmpX A, B" instead of "fcmpX %fcc0, A, B" llvm-svn: 208969
