From 1a91cb0402270a3ce77a9397abda655384d89a43 Mon Sep 17 00:00:00 2001 From: Wouter van Oortmerssen Date: Tue, 5 Feb 2019 01:19:45 +0000 Subject: [WebAssembly] Make disassembler always emit most canonical name. Summary: There are a few instructions that all map to the same opcode, so when disassembling, we have to pick one. That was just the first one before (the except_ref variant in the case of "call"), now it is the one marked as IsCanonical in tablegen, or failing that, the shortest name (which is typically the "canonical" one). Also introduced a canonical "end" instruction for this purpose.
