Bug ID: 205553
Summary: [JSC] Compact Bytecodes more by emitting 1-byte Opcode
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: JavaScriptCore
Assignee: webkit-unassigned at lists.webkit.org
Reporter: ysuzuki at apple.com
When using op_wide16 / op_wide32, we are emitting Opcode in 16bit / 32bit. But Opcode always fit in 8bit.
We should emit 8bit opcode instead, I think this makes Bytecode further compact, and this is nice since bytecode Opcode access becomes alignment-free.
