VM runs a fully-linked program image. \ No newline at end of file diff --git a/docs/specs/pbs/files/PRs para Junie.md b/docs/specs/pbs/files/PRs para Junie.md index e69de29b..9a9661a4 100644 --- a/docs/specs/pbs/files/PRs para Junie.md +++ b/docs/specs/pbs/files/PRs para Junie.md @@ -0,0 +1,374 @@ +## PR-03 — Frame model v0: locals, operand stack, and function metadata + +**Why:** `let x: int = 1` failing usually means locals/frames are not modeled correctly. + +### Scope + +* Define `FunctionMeta`: + + * `code_offset`, `code_len` + * `param_slots`, `local_slots`, `return_slots` + * `max_stack_slots` (computed by verifier or compiler) +* Define `Frame`: + + * `base` (stack base index) + * `locals_base` (or equivalent) + * `return_slots` + * `pc_return` +* Decide representation: + + * Option A (recommended v0): **single VM stack** with fixed layout per frame: + + * `[args][locals][operand_stack...]` + * Use `base + local_index` addressing. + +### Deliverables + +* `CallStack` with `Vec` +* `enter_frame(meta)` allocates locals area (zero-init) +* `leave_frame()` reclaims to previous base + +### Tests + +* locals are isolated per call +* locals are zero-initialized +* stack is restored exactly after return + +### Acceptance + +* Locals are deterministic and independent from operand stack usage. + +--- + +## PR-04 — Locals opcodes: GET_LOCAL / SET_LOCAL / INIT_LOCAL + +**Why:** PBS `let` and parameters need first-class support. + +### Scope + +* Implement opcodes: + + * `GET_LOCAL ` pushes value slots + * `SET_LOCAL ` pops value slots and writes + * `INIT_LOCAL ` (optional) for explicit initialization semantics +* Enforce bounds: local slot index must be within `[0..param+local_slots)` +* Enforce slot width: if types are multi-slot, compiler emits multiple GET/SET or uses `*_N` variants. + +### Deliverables + +* `LocalAddressing` utilities +* Deterministic trap codes: + + * `TRAP_INVALID_LOCAL` + * `TRAP_LOCAL_WIDTH_MISMATCH` (if enforced) + +### Tests + +* `let x: int = 1;

Motivation + +Prometeu aims to be a **deterministic, industrial-grade virtual machine**. +To achieve this, execution errors that are: + +* caused by **user programs**, +* predictable by the execution model, +* and recoverable at the tooling / host level, + +must be **explicitly represented** and **ABI-stable**. + +This specification introduces **Runtime Traps** as a *formal concept*, consolidating behavior that already existed implicitly in the VM. + +--- + +## 2. Definition + +A **Runtime Trap** is a **controlled interruption of program execution** caused by a semantic violation detected at runtime. + +A trap: + +* **terminates the current execution frame** (or program, depending on host policy) +* **does not corrupt VM state** +* **returns structured diagnostic information** (`TrapInfo`) +* **is deterministic** for a given bytecode + state + +A trap is **not**: + +* a debugger breakpoint +* undefined behavior +* a VM panic +* a verifier/load-time error + +--- + +## 3. Trap vs Other Failure Modes + +| Category | When | Recoverable | ABI-stable | Example | +| ------------------ | ---------------------- | ----------- | ---------- | -------------------------------- | +| **Verifier error** | Load-time | ❌ | ❌ | Stack underflow, bad CFG join | +| **Runtime trap** | Execution | ✅ | ✅ | OOB access, invalid local | +| **VM panic** | VM invariant violation | ❌ | ❌ | Handler returns wrong slot count | +| **Breakpoint** | Debug only | ✅ | ❌ | Developer inspection | + +--- + +## 4. Trap Information (`TrapInfo`) + +All runtime traps must produce a `TrapInfo` structure with the following fields: + +```text +TrapInfo { + code: u32, // ABI-stable trap code + opcode: u16, // opcode that triggered the trap + pc: u32, // program counter (relative to module) + message: String, // human-readable explanation (non-ABI) +} +``` + +### ABI Guarantees + +* `code`, `opcode`, and `pc` are ABI-relevant and stable +* `message` is diagnostic only and may change + +--- + +## 5.

Trap Semantics + +### 6.1 Execution + +When a trap occurs: + +1. The current instruction **does not complete** +2. No partial side effects are committed +3. Execution stops and returns `TrapInfo` to the host + +### 6.2 Stack & Frames + +* Operand stack is left in a **valid but unspecified** state +* Call frames above the trapping frame are not resumed + +### 6.3 Host Policy + +The host decides: + +* whether the trap terminates the whole program +* whether execution may be restarted +* how the trap is surfaced to the user (error, log, UI, etc.) + +--- + +## 7. Verifier Interaction + +The verifier **must prevent** traps that are statically provable, including: + +* stack underflow +* invalid control-flow joins +* invalid syscall IDs +* incorrect return slot counts + +If a verifier rejects a module, **no runtime traps should occur for those causes**. + +--- + +## 8. What Is *Not* a Trap + +The following are **VM bugs or tooling errors**, not traps: + +* handler returns wrong number of slots +* opcode implementation violates `OpcodeSpec` +* verifier and runtime disagree on stack effects + +These must result in **VM panic**, not a trap. + +--- + +## 9. Versioning Policy + +* Trap codes are **ABI-stable within a major version** (v0) +* New trap codes may only be added in a **new major ABI version** (v1) +* Removing or reinterpreting trap codes is forbidden + +--- + +## 10. Summary + +Runtime traps are: + +* an explicit part of the Prometeu execution model +* deterministic and ABI-stable +* reserved for **user-program semantic errors** + +They are **not** debugging tools and **not** VM panics. + +This spec formalizes existing behavior and freezes it for PBS v0. + +--- diff --git a/docs/specs/pbs/files/PRs para Junie.md b/docs/specs/pbs/files/PRs para Junie.md index c63d44aa..b74f4a57 100644 --- a/docs/specs/pbs/files/PRs para Junie.md +++ b/docs/specs/pbs/files/PRs para Junie.md @@ -1,26 +1,3 @@ -## PR-09 — Debug info v0: spans, symbols, and traceable traps - -**Why:** Industrial debugging requires actionable failures. - -### Scope - -* Add optional debug section: - - * per-instruction span table (`pc -> (file_id, start, end)`) - * function names -* Enhance trap payload with debug span (if present) - -### Tests - -* trap includes span when debug present -* trap still works without debug - -### Acceptance - -* You can pinpoint “where” a trap happened reliably. - ---- - ## PR-10 — Program image + linker: imports/exports resolved before VM run **Why:** Imports are compile-time, but we need an industrial linking model for multi-module PBS. -- 2.47.2 From 83e24920b4af571bfed86db97f470543aa0da932 Mon Sep 17 00:00:00 2001 From: Nilton Constantino Date: Sat, 31 Jan 2026 18:48:22 +0000 Subject: [PATCH 52/74] pr 49 --- crates/prometeu-bytecode/src/abi.rs | 10 + crates/prometeu-bytecode/src/v0/mod.rs | 155 +++++- .../src/virtual_machine/linker.rs | 294 ++++++++++++ .../src/virtual_machine/local_addressing.rs | 1 + .../prometeu-core/src/virtual_machine/mod.rs | 5 +- .../src/virtual_machine/program.rs | 43 +- .../src/virtual_machine/virtual_machine.rs | 443 ++++++++---------- ...ime Traps.md => Prometeu Runtime Traps.md} | 0 docs/specs/pbs/files/PRs para Junie.md | 67 --- 9 files changed, 707 insertions(+), 311 deletions(-) create mode 100644 crates/prometeu-core/src/virtual_machine/linker.rs rename docs/specs/pbs/{Runtime Traps.md => Prometeu Runtime Traps.md} (100%) diff --git a/crates/prometeu-bytecode/src/abi.rs b/crates/prometeu-bytecode/src/abi.rs index 6feb351a..88445f5c 100644 --- a/crates/prometeu-bytecode/src/abi.rs +++ b/crates/prometeu-bytecode/src/abi.rs @@ -50,6 +50,14 @@ pub const TRAP_INVALID_FUNC: u32 = 0x0000_000B;

PBS v0 Module Structure +## 4. Module Model (Compile-Time Only) -A PBS v0 module consists of: +### 4.1 Module Definition -* `code: [u8]` — final bytecode stream -* `functions: [FunctionMeta]` — function table -* `const_pool: [Const]` — constant pool -* (optional) metadata (build id, debug info, hashes) +* A module is a directory inside a project +* Each module contains one or more `.pbs` source files -The module is **self‑contained**: no external symbols, imports, or relocations. +### 4.2 Visibility Rules + +Visibility is enforced **exclusively at compile time**: + +* `file`: visible only within the same source file +* `mod`: visible within the same module +* `pub`: visible to importing modules or projects + +The VM has **zero awareness** of visibility. --- -## 5. Function Table and CALL Semantics +## 5. Imports & Dependency Resolution -### 5.1 Function Identification +### 5.1 Import Syntax -Functions are identified **by index** in the function table. +Imports reference **projects and modules**, never files: + +``` +import @core:math +import @input:pad +``` + +### 5.2 Resolution Pipeline + +The compiler performs the following phases: + +1. Project dependency graph resolution (via `prometeu.json`) +2. Module discovery +3. Symbol table construction +4. Name and visibility resolution +5. Type checking + +Any failure aborts compilation and **never reaches the VM**. + +--- + +## 6.

Control Flow (JMP / Branches) +## 7. Runtime Execution Contract -* All jump targets are **relative to the start of the current function**. -* Targets must land on **valid instruction boundaries**. +### 7.1 VM Input Requirements -This eliminates the need for global relocations. +The Prometeu VM accepts **only linked PBS blobs**. + +It assumes: + +* All function references are valid +* All jumps target instruction boundaries +* No unresolved imports exist + +### 7.2 VM Responsibilities + +The VM is responsible for: + +1.
