778a559d303abfb1b980ef6b7503cb3d44d62487 [JSC] WASM debugger: answer qWasmStackValue for caller frames
not a security fix
confidence 0.12
signal score 16.04
Source/JavaScriptCore/jit
Classified as not security-relevant.
Triage note: Adds wasmIPIntMCRegister plumbing and restore-frame skipping to WasmDebugServerUtilities/WasmQueryHandler so the wasm debugger can report caller operand-stack depth; replaces some RELEASE_ASSERT with graceful returns on tail calls. Debugger-only (Wasm::DebugServer) robustness, not an attacker-reachable fix.
This commit was flagged by the signal scorer and reviewed by AI (not a human). It is listed only so the triage is auditable; there is no root-cause analysis because this is not a vulnerability fix.
