aheejin · memfrob · commit 565eeca18caf · 2022-10-04T17:55:08.000-04:00
We decided to change `catch_all`'s opcode from 0x05, which is the same as `else`, to 0x19, to avoid some complicated handling in the tools. See: WebAssembly/exception-handling#147 Reviewed By: sbc100 Differential Revision: https://reviews.llvm.org/D96863
