compiler-80cc skillA
compiler-80cc is agent-read markdown (skill) from feilipu/8085-skills: 80cc experimental/alternate C compiler in z88dk. Use when -compiler=80cc or working under src/80cc..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Compiler — 80cc Binary: `z88dk-80cc`. Source: `src/80cc/`. Rules file: `lib/80cc_rules.1`. ## Agent facts 1. Select via `zcc -compiler=80cc` when the target allows it. 2. `-compiler=multi` also runs 80cc. It always compiles `80cc-sp`. It compiles `80cc-fp` when 80cc treats the CPU as having IX. Spec: `src/zcc-multi/zcc-compiler-multi.md`. 3. Do not assume sccz80 or sdcc runtime helpers match 80cc output. 4. Prefer reading `src/80cc` notes for current status before large work. 5. Rebuild: `make -C src/80cc PREFIX=$(pwd)` from the z88dk root, then `make -C src/80cc PREFIX=$(pwd) install`. 6. The `--version` / `-h` banner comes from `src/config.h` `Z88DK_VERSION`. That string can be stale after a rebuild. Prove a hunk with `strings bin/z88dk-80cc`, not the banner. 7. kc160 `mul de,hl` is **integer** 16×16. `_Float16` / accum16 stay on `l_f16_mul` / `l_fix16_*`. Do not emit IR_MUL for those (math16 80cc kc160 suite: `1.5*1.5` and `0*Inf`). ## Frame pointer (Z80 benches) | Flag | Meaning | |------|---------| | `-fframe-pointer` | IX is the frame pointer (`ix+d` locals). Use on **Z80** 80cc TIMER / PRINTF recipes, including `--math-mbf32`. | …

How to install
mdr add feilipu/8085-skills/compiler-80cc@git:20260919.216763amdr add feilipu/8085-skills/compiler-80cc@sha256:cba075bb49e1ee63Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
