sccz80 classic C compiler for z88dk: calling conventions, copt peephole path, 8080/8085/z80 runtime under libsrc/l/sccz80. Use when debugging sccz80 codegen or classic -compiler=sccz80 builds.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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: …

How to install
mdr add feilipu/8085-skills/compiler-sccz80@sha256:5679ef704e9b2fabThe line at the top of this page pins the label git:20260919.216763a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
