[PATCH] D68916: [ARM] Accept ldrb.w mnemonic for certain addressing modes (PR43382)

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Adding aliases seems like the right approach; we have aliases for a bunch of other instructions.

I'm not sure why you need the AsmMatchConverter, though; needs a comment to explain.

+def : t2InstAlias<"ldrb${p}.w $Rt, $Rn$offset", (t2LDRB_POST GPR:$Rt, GPR:$Rt, addr_offset_none:$Rn, t2am_imm8_offset:$offset, pred:$p)>;

----------------
Why is Rt listed twice here?
