- Sep 13, 2026 Calling Conventions on an Operand Stack How arguments, return values, receivers, and frame transitions are encoded in a stack machine, and why the receiver occupies slot zero of a method frame. language runtimes
- Jul 20, 2026 Stack Machines and Register Machines as Bytecode Targets Why bytecode formats choose implicit stack operands or named registers, and what that choice costs in encoding width, instruction count, and verifier complexity. language runtimes
- Jun 10, 2026 Superinstruction Selection and In-Place Opcode Quickening How interpreters fuse frequent opcode pairs and rewrite instructions after first execution, and why every such rewrite needs an invalidation path. language runtimes
- Nov 26, 2025 Computed Goto and Direct Threading in Bytecode Interpreters How the dispatch loop dominates interpreter cost, and why a table of label addresses beats a switch statement on the same instruction stream. language runtimes
- Nov 20, 2025 Bytecode Verification and Stack Map Frames How a verifier proves that operand stack depths and types are consistent at every branch target, and why stack map frames replaced full dataflow analysis. language runtimes
- Sep 24, 2025 How an Interpreter Lays Out a Stack Frame The header, locals, operand stack, and spill area of an interpreter frame, and why the frame is allocated as one block with a fixed maximum size. language runtimes
- Sep 23, 2025 Shipping Shared Code Outside the Release Cycle Delivering the shared layer as a replaceable bundle decouples it from the native shell, which turns every release into a matrix of shell and bundle versions and every rollback into a data-compatibility problem. mobile computing
- Mar 20, 2025 Constant Pools and Operand Encoding in Bytecode Why bytecode instructions reference large constants indirectly through a pool, how the pool is laid out, and what the fixed-width index fields cost. language runtimes
- Jan 27, 2024 Stack Bytecode: Fixed Stack Effects and the Dispatch Loop How a stack machine encodes operands implicitly in the stack pointer, why verifiers care about static stack depth, and what the dispatch loop costs per instruction. programming languages
- Jan 21, 2024 Exception Tables and Frame Unwinding in Bytecode How a thrown exception finds its handler using a table of protected ranges, and why the table is separate from the code rather than encoded as instructions. language runtimes
- Feb 24, 2023 Line Tables, Breakpoints, and Single Stepping in an Interpreter How a debugger maps a bytecode offset back to a source line, how breakpoints are placed without corrupting the code, and what stepping costs per instruction. language runtimes
- Jan 30, 2023 Register Bytecode and Windowed Register Allocation in Lua How a register-based VM names operands inside a per-call window, why that cuts instruction count, and what the compiler must compute to keep the window small. programming languages
