80cc experimental/alternate C compiler in z88dk. Use when -compiler=80cc or working under src/80cc.
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 — 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. The stitch keeps one string pool (the sccz80 `dumplits` image), not one pool per variant that won a function. Matching 80cc bytes keep the sccz80 label and offsets. A different pool is merged by C string. 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`). …

How to install
mdr add feilipu/8085-skills/compiler-80cc@sha256:48364d31787cf8b2The line at the top of this page pins the label git:20261103.10fa9ce, 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.
