RISC-V's `encode_one` is a +dozen lines of shifts. **Conclusion: the `encode_one`/`decode_one` core +and the `Encoding` struct do not generalize — but the loop that drives +them does (§7).** + +### 2.2 Memory addressing — **high divergence** + +| ISA | Addressing modes | +|---|---| +| x86 | `[base + index*scale + disp32]`, RIP-relative, segment override, addr-size override | +| RISC-V | `disp12(base)` only — no index, no scale | +| MIPS | `imm16(base)` only | +| ARM64 | `[base]`, `[base,#imm]`, `[base,Xm{,LSL#n}]`, `[base,Wm,SXTW]`, pre/post-index `[base,#imm]!` / `[base],#imm`, PC-rel literal | + +The x86 `Memory` bit_field (with `segment`, `addr_size_override`, +index+scale) is deeply x86-flavored. RISC-V's memory is `{base, i32 disp}`. +ARM adds **writeback** (a mode x86 cannot express) and extend/shift on the +index. **Conclusion: `Memory` is per-arch.** What generalizes is only the +*role*: a `MEMORY`-kind operand carrying an arch-defined payload. + +### 2.3 Immediates & operand size — **moderate divergence** + +- The *value* (an `i64`) generalizes perfectly. +- The *encoding* does not: RISC-V scatters immediate bits across fields + (B-type, J-type) and shifts them; ARM has bitmask-immediate and shifted + forms. All of that lives inside `encode_one`; the `Operand` just holds + the clean value. +- **Size association differs:** x86 carries an explicit `size: u8` and + uses it to select an encoding; RISC-V/ARM bake width into the mnemonic + (`LW` vs `LD`, `W0` vs `X0`). Keep `size` in the shared operand shape as + a *carrier*; let each arch decide how much it matters. + +### 2.4 Relocations — **moderate divergence (structurally aligned)** + +The `Relocation` *struct* (offset, symbol/label, addend, type, size) +mirrors ELF `rela` and is universal. The *type enum* is per-arch and much +larger on RISC-V (paired `PCREL_HI20`/`PCREL_LO12`, `CALL`, `BRANCH`, +`JAL`, `HI20`, `LO12_I/S`, …) because PC-relative addressing needs +instruction *pairs* (AUIPC+ADDI). **Conclusion: share the struct shape, +make the type enum a per-arch parameter.** + +### 2.5 Registers — **low/structural divergence** + +The `(class, hw_number)`-packed `distinct u16` scheme generalizes well. +What differs: +- x86: REX/EVEX extension bits, AH↔SPL aliasing, RIP pseudo-reg. +- RISC-V: clean 5-bit fields, `x0`=hardwired zero, ABI names + (`zero/ra/sp/gp/tp/t0../s0../a0..`), separate `f`/`v` files. +- ARM64: reg #31 means **SP or XZR depending on instruction** (a + decode/print-time disambiguation x86 never needs); `w`/`x` and + `b/h/s/d/q` views. +**Conclusion: share the *layout convention* + `reg_hw`/`reg_class` +accessors; per-arch owns classes, enums, names, and extension semantics.** + +### 2.6 Mnemonics — **content differs, shape identical** + +Per-arch `enum u16`, `INVALID=0`. Nothing to share but the convention. + +### 2.7 Labels — **no divergence** + +`labels.odin` is pure bookkeeping. The array-index model +(`Label_Definition`, `label`, `label_forward`, `label_set_at`, +`Label_Map`, `label_named`, `label_reserve`, `label_set`) lives in +`isa/labels.odin` and is parametric over the Instruction type. **Fully +shared.** Each arch's `encode()` rewrites label_defs from instruction +indices to byte offsets between pass 1 and pass 2. + +### 2.8 Errors / Result — **low divergence** + +`Result` is universal. `Error` is universal in shape. `Error_Code` splits +into a **shared core** (`NONE, BUFFER_OVERFLOW, INVALID_MNEMONIC, +NO_MATCHING_ENCODING, BUFFER_TOO_SHORT, INVALID_OPCODE, LABEL_OUT_OF_RANGE, +…`) and **arch-specific** extras (`INVALID_MODRM/SIB/VEX/EVEX, +TOO_MANY_PREFIXES` on x86; RISC-V would add `MISALIGNED_IMMEDIATE`, +`INVALID_ROUNDING_MODE`, …). + +### 2.9 Printer — **framework universal, formatting per-arch** + +Shareable: `Token`, `Token_Kind` (the kinds are generic), `Print_Options`, +the builder/number-formatting helpers, and the whole family of output +sinks (`sbprint/print/aprint/tprint/bprint/fprint/wprint` + `ln`). Per-arch: +`register_name`, `print_memory` (syntax differs wildly), +`mnemonic_to_string`, and the size-suffix convention (x86's `.b/.w/.d` is +x86-only; RISC-V puts width in the mnemonic). + +### Divergence summary + +| Component | Verdict | What's shared | What's per-arch | +|---|---|---|---| +| Labels | ✅ shared | everything | — | +| Result / Error struct | ✅ shared | struct shapes | error-code extras | +| Relocation struct | ✅ shared | struct shape | type enum | +| Printer framework | ◑ split | tokens, options, sinks, num-fmt | reg/mem/mnemonic formatting | +| Register scheme | ◑ split | layout + `reg_hw`/`reg_class` | classes, enums, names, ext bits | +| Operand model | ◑ split | kind tag + union discipline + `size` carrier | `Memory`, `flags` payloads | +| Encode/decode **driver** | ◑ shared via generics | two-pass loops, label/reloc resolution | the per-instruction hook | +| `Instruction` | ✗ per-arch | shape convention only | concrete struct | +| `Mnemonic` | ✗ per-arch | convention (u16, INVALID=0) | the enum | +| `Encoding` + tables | ✗ per-arch | codegen *pattern* | schema + data | +| `encode_one`/`decode_one` | ✗ per-arch | nothing | all of it | +| Memory addressing | ✗ per-arch | operand *role* | the model | + +--- + +## 3.

Still 100% compile-time, +zero overhead. + +### 5.3 Layer C — runtime multi-target facade (opt-in, for tools) + +For a disassembler or JIT that selects the arch *at runtime*, `isa` +provides a vtable populated by each arch: + +```odin +// isa/target.odin +Target :: struct { + name: string, + decode: proc(data: []u8, out: ^Decoded) -> Result, // bytes → generic Decoded + print: proc(d: ^Decoded, opts: ^Print_Options) -> string, + inst_align: u32, // 1 for x86, 4 for riscv/arm64/mips + max_inst: u32, // 15 for x86, 4 for riscv (8 for C-pairs), 4 for arm64 +} +// each arch: x86.TARGET: isa.Target = { … } +``` +This boundary trades in **bytes and a generic `Decoded` view**, not the +concrete `Instruction`, so it never forces a unified instruction struct. +It carries a proc-pointer indirection — acceptable for a tool that has +already paid a `switch arch` somewhere, and never on Layer A's path. + +--- + +## 6.

Odin monomorphizes +these at compile time → **no runtime cost, real code sharing.** + +```odin +// isa/pipeline.odin (sketch) +encode_stream :: proc( + instructions: []$I, + label_defs: []Label_Definition, + code: []u8, + relocs: ^[dynamic]Relocation, + errors: ^[dynamic]Error, + encode_one: proc(inst: ^I, out: []u8, code_pos: u32, + relocs: ^[dynamic]Relocation, errors: ^[dynamic]Error) -> (n: u32, ok: bool), + resolve := true, base_address: u64 = 0, +) -> Result { + // PASS 1: for each inst → record offset, call encode_one, advance + // PASS 1.5: rewrite label_defs inst-index → byte-offset (identical on every arch) + // PASS 2: resolve relocations / patch / spill unresolved (identical on every arch) +} +``` + +x86's current `encode()` becomes a thin wrapper that passes its +`encode_one` (the prefix/ModRM/SIB body); RISC-V's wrapper passes its +12-line bitfield packer. The label/relocation machinery — the part that's +easy to get subtly wrong — is written and tested **once**. + +Caveats (arch-specific passes that stay out of the shared driver): +- **RISC-V pseudo-ops** (`li`, `call`, `la`, `j`) expand to 1–2 real + instructions; needs an arch pre-lowering pass. +- **Branch relaxation** (short↔long form) is arch-specific. +- **ARM literal pools / constant islands** are an extra emission phase. + +These plug in *around* the shared driver, not inside it. + +--- + +## 8.

Recommended next steps + +1. **Stabilize x86 first.** Resolve the constructor-rename drift noted in + [x86_api.md](x86_api.md#known-drift) (tests/README vs `operands.odin`) + so x86 is the clean reference the contract is extracted from. +2. **Extract `isa`** by lifting the *already-arch-independent* files: + `labels.odin`, the `Relocation`/`Error`/`Result` types, and the printer + framework (tokens/options/sinks/number-formatting). Make `x86` + re-export them. This is a low-risk refactor that proves the split. +3. **Add the parametric `encode_stream`/`decode_stream`** to `isa` and + reduce x86's `encode`/`decode` to wrappers. Validate against the + existing test suite (same bytes out). +4. **Write the RISC-V package against the contract** (§6) and the mapping + (§8), reusing `isa` wholesale. Build its `encoding_table.odin` by hand, + then port the two generators. +5. **Only if a runtime-multi-target tool appears**, add the `Target` + vtable (§5.3). Don't build it speculatively. + +The deliverable order matters: every step is independently shippable, and +x86 keeps working (and keeps its performance) throughout. + +--- + +## 10. One-paragraph summary + +Make `isa` own the parts that are the same on every ISA — labels, +relocations, errors/result, the print framework, and (via Odin +parametric polymorphism) the encode/decode driver loops. Make each arch +package own its registers, memory model, operands, mnemonics, encoding +tables, and the actual `encode_one`/`decode_one` bytes. Bind the family +together with a strict **naming contract** so packages are drop-in +swappable at source level with zero runtime cost, and reserve a single +opt-in runtime `Target` vtable for the rare tool that needs to choose an +architecture dynamically. x86 keeps every cycle of its current +performance; RISC-V (and later ARM/MIPS) gets the boring 60% for free and +writes only the 40% that is genuinely its own. diff --git a/core/rexcode/docs/mips_platforms.md b/core/rexcode/docs/mips_platforms.md new file mode 100644 index 000000000..b91cc8aa3 --- /dev/null +++ b/core/rexcode/docs/mips_platforms.md @@ -0,0 +1,79 @@ +# MIPS targets and extensions — platform catalog + +> What's worth supporting in `rexcode/mips/` (or a sibling subpackage) and +> what isn't, framed around the actual hardware that runs MIPS. + +## Mainline consoles (MIPS-family CPUs) + +| Platform | CPU | Base ISA | Custom extension | Status | +|---|---|---|---|---| +| **PS1 / PSX** | Sony R3000A | MIPS I (no MMU) | **GTE** (COP2) — geometry transformation engine | ✅ done | +| **PSX IOP / PS3 IOP** | LSI CW33300 / "IOP" | MIPS I | (none — same as PS1 CPU) | ✅ covered by MIPS I | +| **N64** | NEC VR4300i | MIPS III + partial MIPS IV FPU | none on main CPU | ✅ covered by MIPS III + IV + FPU | +| **N64 RSP** | RCP "Reality Signal Processor" | custom MIPS R4000 subset | **VU** (128-bit vector unit, 32 vec regs); also drops mult/div/FPU/TLB | ⚠ **needs its own subpackage** — different ISA | +| **N64 RDP** | (display processor) | not a CPU, command-stream — not in scope | | | +| **PS2 EE** | Sony R5900 (Toshiba) | MIPS III + MIPS IV (MOVN/MOVZ) | **MMI** (128-bit packed SIMD via MMI0-3), **LQ/SQ**, second HI/LO, VU0-macro | ✅ done (MMI; VU0-macro forms TBD) | +| **PS2 VU0 / VU1** | "Vector Unit" | not MIPS — VLIW pair (upper + lower microcode) | — | 🚧 **separate ISA** — sibling `vu/` subpackage if needed | +| **PS2 IOP** | (R3000A reused) | MIPS I | — | ✅ covered | +| **PSP** | Sony "Allegrex" | MIPS32 R2 (+ R2 bitfield + rotates + SEB/SEH + BITREV) | **VFPU** (vector FPU, 128 32-bit regs in 8×4×4 matrices), Allegrex-specific BITREV/etc. | ⚠ Mnemonics enumerated, encodings TBD | +| **PSP Media Engine** | (second Allegrex) | same as Allegrex | same VFPU | (covered when PSP CPU is) | +| **PSV / Vita PS1-mode** | Cortex-A9 emulating R3000 | — (host is ARM) | — | | + +## Arcade and other + +| Platform | CPU | Base ISA | Extension | Status | +|---|---|---|---|---| +| **SNK Hyper Neo Geo 64** | NEC VR4300 | MIPS III | none | ✅ covered | +| **Konami Hornet** (arcade) | various | MIPS-family | none | ✅ covered | +| **Sega Model 3** step 1.x | MIPS — IDT R5000 | MIPS IV | none | ✅ covered | + +## Modern / embedded MIPS with vendor extensions + +| Platform | CPU | Base | Extension | Status | +|---|---|---|---|---| +| **Ingenic XBurst** (Jz47xx) — old MP3/Android handhelds | XBurst | MIPS32 R2 | **MXU** (Multimedia Unit, custom SIMD), DSP ASE | 🚧 DSP enumerated, **MXU is XBurst-only** — defer | +| **Broadcom MIPS** (older routers) | bcm473x / bcm63xx | MIPS32 R2/R5 | DSP ASE common | DSP enumerated; encodings TBD | +| **Atheros / Qualcomm** (router SoC) | MIPS32 R2 | MIPS32 R2 | DSP common | as above | +| **MediaTek MIPS** (older routers) | MIPS32 R2 | MIPS32 R2 | DSP | as above | +| **Loongson 2/3** (China desktop) | Loongson | MIPS64 + custom | **Loongson MMI** (note: different from PS2 MMI!), **LSX** (128-bit), **LASX** (256-bit).

Polluting the MIPS namespace. +- The RSP's COP2 encoding *collides* with PS1 GTE bit patterns (both use op=0x12 with the CO bit) so a single decode table can't disambiguate without an ISA gate. +- The RSP's vector loads encode element offset + size in the cofun bits in ways that have no MIPS analogue. + +Cleaner: `rexcode/rsp/` as a sibling subpackage. It will reuse `isa/` (labels, relocs, errors, print framework) and parallel `mips/`'s shape (registers / operands / instructions / mnemonics / encoding_table / encoder / decoder / printer).
