Develop, build, test, debug, and optimize the dcc host toolchain: dcc, dccpeep, dccrtlstrip, dccmake, m80c, l80c, dcc-debug-host, the debugger I/O adapter ABI/example, and DCCRTL.MAC. Use for compiler, MIR backend, optimizer, runtime, GDB/MI debugger, debug metadata/fixtures, regression-suite, or toolchain build work. Use dcc-cpm-z80 for ordinary target applications.
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
# dcc project dcc is a cross toolchain. Host programs emit Z80 assembly and CP/M 2.2 executables: `dcc -> dccpeep (optional) -> m80c -> dccrtlstrip -> m80c -> l80c -> ntvcm` Production function bodies are generated from MIR only. AST processing after parsing is metadata-only; legacy body emission, capture/replay, and speculative legacy register-allocation retries do not exist. ## Source map | Surface | Location | | --- | --- | | Driver, parser, symbols | `src/dcc/dcc.c`, `dcc_func.c`, `dcc_symbols.c` | | Preprocessor | `src/dcc/dcc_preproc.c`, `dcc_pp_expr.c` | | Function-local AST | `dcc_ast.c`, `dcc_ast.h`, `dcc_ast_build.c` | | AST classifiers and capture | `dcc_ast_classify.c`, `dcc_ast_support.c`, `dcc_ast_stmt_classify.c`, `dcc_ast_capture.c`, `dcc_ast_internal.h` | | Non-emitting AST metadata | `dcc_ast_metadata.c`, `dcc_ast_stmt_meta.c` | | MIR lowering and verification | `dcc_mir.c`, `dcc_mir.h` | | Independent MIR dominance verification | `dcc_mir_verify.c` | | MIR selection and cost policy | `dcc_mir_select.c` | | General homed/spilled emitters | `dcc_mir_homed_cfg.c`, `dcc_mir_spilled_cfg.c` | …

How to install
mdr add davidly/dcc/dcc-project@sha256:4cc3132f4292bfb6The line at the top of this page pins the label git:20261002.2435183, 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.
