For strict equal boolean literal like "a===true" or "a===false", we could generate TestReferenceEqual rather than TestStrictEqual. And in `execution_result()->IsTest()` case, we could directly emit JumpIfTrue/JumpIfFalse. E.g. ``` a === true ``` Generated Bytecode From: ``` LdaGlobal Star1 LdaTrue TestEqualStrict ``` To: ``` LdaGlobal Star1 LdaTrue TestReferenceEqual ``` E.g. ``` if (a === true) ``` Generated Bytecode From: ``` LdaGlobal Star1 LdaTrue TestEqualStrict JumpIfFalse ``` To ``` LdaGlobal JumpIfTrue Jump ``` Bug: v8:6403 Change-Id: Ieaca147acd2d523ac0d2466e7861afb2d29a1310 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3568923 Reviewed-by: Leszek Swirski <leszeks@chromium.org> Reviewed-by: Tobias Tebbi <tebbi@chromium.org> Commit-Queue: 王澳 <wangao.james@bytedance.com> Cr-Commit-Position: refs/heads/main@{#79935} |
