arsenm added inline comments.
================
Comment at: llvm/lib/Target/Sparc/SparcInstrInfo.td:1834-1838
+// Special case %fq as the register is also used in V8
+// (albeit with different instructions and encoding)
+// This allows us to reuse the register definition and
+// the "%fq" designation while giving it a different encoding.
+let Uses = [FQ], rs1 = 15, rs2 = 0 in
----------------
I'm confused by what this comment means, as you're defining a new instruction. Is the intent to define an assembler alias only?
