Motivation + +PBS is designed to be executed by a small, deterministic virtual machine embedded in PrometeuOS. To keep the VM **simple, secure, and optimizable**, all *semantic linking* must happen **before runtime**, in the compiler/tooling layer. + +The VM is **not a linker**.

What “Linking” Means in PBS + +In PBS, *linking* refers to resolving all symbolic or relative references into a **final, index‑based layout**. + +This includes: + +* Function call resolution +* Control‑flow targets (JMP / conditional branches) +* Constant pool indexing +* Syscall signature binding + +All of this must be **fully resolved by the compiler/toolchain**. + +--- + +## 4. PBS v0 Module Structure + +A PBS v0 module consists of: + +* `code: [u8]` — final bytecode stream +* `functions: [FunctionMeta]` — function table +* `const_pool: [Const]` — constant pool +* (optional) metadata (build id, debug info, hashes) + +The module is **self‑contained**: no external symbols, imports, or relocations. + +--- + +## 5.

Control Flow (JMP / Branches) + +* All jump targets are **relative to the start of the current function**. +* Targets must land on **valid instruction boundaries**. + +This eliminates the need for global relocations. + +--- + +## 7.

Legacy and Compatibility Policies + +Legacy formats (e.g. PPBC) may be supported behind explicit policies. + +Example: + +* Legacy `CALL addr` encodings are **rejected** under Policy (A) +* Only `CALL func_id` is valid in PBS v0 + +Compatibility handling is **orthogonal** to the linking model. + +--- + +## 10.
