Deep dive into YARV (Yet Another Ruby VM), Ruby's virtual machine that executes compiled bytecode. Explains how YARV uses a dual-stack architecture: one internal stack for tracking intermediate values and instructions, and another for managing Ruby's call stack. Walks through detailed execution flow of simple Ruby code, showing how YARV instructions like putself, putobject, and opt_plus manipulate the stack, handle method calls, and manage program flow. Covers stack frames, program counters, and the rb_control_frame_t structure that tracks execution state.
