Hi V8 team,
I’m currently studying V8’s support for Intel CET (Control-flow Enforcement Technology) on x64, and I came across the following comment in the shadow stack handling code: // We subtract a frame from visited_frames because otherwise the // shadow stack will drop the underlying interpreter entry trampoline // in which the handler runs. // // An interpreted frame cannot be the first frame we look at // because at a minimum, an exit frame into C++ has to separate // it and the context in which this C++ code runs. https://chromium-review.googlesource.com/c/v8/v8/+/3289637/12/src/execution/isolate.cc An interpreted JavaScript frame must never appear directly adjacent to C++ frames—it must always be separated by at least one exit frame. Where I can find it's documents or code? -- -- v8-dev mailing list [email protected] http://groups.google.com/group/v8-dev --- You received this message because you are subscribed to the Google Groups "v8-dev" group.
