When this occurs, we\u0027ll scavenge a scratch\n\u003e register to be able to hold the correct stack offset for frame locals.\n\u003e\n\u003e This completes reapplying #84114.\n\u003e\n\u003e Fixes #48911\n\u003e Fixes #75944\n\u003e Fixes #87154\n\nThis reverts commit 0abb7791614947bc24931dd851ade31d02496977.\n",
