// [SMDOC] VM stack layout // // A JSRuntime's stack consists of a linked list of activations. Every // activation contains a number of scripted frames that are either running in // the interpreter (InterpreterActivation) or JIT code (JitActivation). The // frames inside a single activation are contiguous: whenever C++ calls back // into JS, a new activation is pushed. // // Every activation is tied to a single JSContext and JS::Compartment. This // means we can reconstruct a given context's stack by skipping activations // belonging to other contexts. This happens whenever an embedding enters the JS // engine on cx1 and then, from a native called by the JS engine, reenters the // VM on cx2.
// Interpreter frames (InterpreterFrame) // // Each interpreter script activation (global or function code) is given a // fixed-size header (js::InterpreterFrame). The frame contains bookkeeping // information about the activation and links to the previous frame. // // The values after an InterpreterFrame in memory are its locals followed by its // expression stack. InterpreterFrame::argv_ points to the frame's arguments. // Missing formal arguments are padded with |undefined|, so the number of // arguments is always >= the number of formals. // // The top of an activation's current frame's expression stack is pointed to by // the activation's "current regs", which contains the stack pointer 'sp'. In // the interpreter, sp is adjusted as individual values are pushed and popped // from the stack and the InterpreterRegs struct (pointed to by the // InterpreterActivation) is a local var of js::Interpret.
