[PATCH] D29133: [PowerPC][Altivec] Add some extended mnemonics

[Nemanja Ivanovic via Phabricator via llvm-commits]

nemanjai added inline comments.


================
Comment at: lib/Target/PowerPC/PPCInstrVSX.td:1450
+// be emitted with a VSX reg. So leave Emit = 0 here.
+def : InstAlias<"mfvrd $rA, $XT",
+                (MFVRD g8rc:$rA, vrrc:$XT), 0>;
----------------
@hfinkel Do you think this is an acceptable way to get this support implemented? Or do you have a preferred suggestion? Maybe some custom handling of the register operand (or even the mnemonic itself) in the Asm parser/printer or something along those lines...

Once we decide how we want to approach this, we can add a test case.
