Indexed from public GitHub and served as immutable, content-addressed versions.

The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Compiler — sccz80 Binary: `z88dk-sccz80` (normally via `zcc`). Source: `src/sccz80/`. ## Agent facts | Topic | Detail | |-------|--------| | Default | Many classic targets use sccz80 | | Peephole | `z88dk-copt` + `lib/z80rules.*` on **compiler output only** | | Runtime | `libsrc/l/sccz80/` per CPU (`5-z80`, `7-8085`, `8-8080`, …) | | Inline ints | May load `z80rules.8` — see `tool-copt` | | Float rewrite | sccz80 may rewrite `1.0f/x` → `inv(x)`; force runtime numerator to hit `fsdiv` | ## Condensed wiki # Tool — z88dk-sccz80 Native C compiler. Normally invoked through **zcc**, not directly. ## When to use direct invocation Rare. Prefer `zcc +target …`. Use the binary directly only when debugging the compiler front end. ## Select via zcc Default for most classic CLIBs and for `-clib=new`. See [Compilers](Compilers). ## Help ```text Small-C/Plus - z80 Crosscompiler Version: 25141-6b30e0885e-20260716 (C) 1980-2025 Cain, Van Zandt, Hendrix, Yorston, z88dk Usage: z88dk-sccz80 [flags] [file] -v -verbose Be verbose -h -help Show this help page -o -output Set the output filename CPU Targetting: …
