[PATCH] D60966: [WebAssembly] Emit br_table for most switch instructions

[Dan Gohman via Phabricator via llvm-commits]

sunfish added a comment.

The theory here is that br_table represents the performance characteristics of a jump table, while br_if represents the performance characteristics of a branch. In hardware, a small switch with 3 cases is often more efficient with a couple of conditional branches than a jump table.
