Description Asumu Takikawa 2022-12-16 14:45:28 PST

LLInt for Wasm is hitting an opcode limit, which is preventing Wasm patches that add more instructions from landing.

It's possible to easily free two opcodes for GC proposal instructions, which is a short-term fix that could help land some patches.
