pcc 0.1.2

Highlights since v0.1.1

• Nested-def hoisting — capture-name management, sibling resolution, free-variable filtering for renamed/discard captures
• Chained comparisons — a < b < c lowers with proper Python and-semantics
• Lexer self-host — int-based code-point predicates in py_lex.py (no str.is* calls, lexer compiles natively under self backend)
• Native builtins:
  • int(x) on tagged int / DynType — no detour through str
  • float("inf" | "-inf" | "nan")
  • DynType-backed double IR marshals to pcc float objects
• enumerate fixes — index pinned to i64, boxed via py_int_from_i64 when storage slot is a pointer
• Slice fixes — tuple[lo:hi:step] now goes through py_tuple_slice (was wrongly routed to list slice)
• ord(s[i]) fast path for StrType subscript
• Class info schema (ClassInfo.extern_method_defs) for pcc-native bootstrap

Repo hygiene

• .gitignore adds tmp_probe_*.py; 7 stale probes untracked

Install

pip install python-cc==0.1.2

pcc 0.1.1

Highlights since v0.1.0

• Self backend — aarch64 Darwin + x86_64 Linux paths, with target-specific parsing/dispatch/emission, bootstrap + promotion gates, Docker coverage, and C-testsuite runners
• Native stdlib dispatch — os.environ.get, os.getcwd, os.access, os.path.{dirname,isfile,isdir,getmtime,abspath,join}, sys.platform, and print(*args, file=stderr|stdout, flush=...) — no longer route through CPython
• Python frontend — numeric method fallback (int.to_bytes etc.), for...else, top-level try / with / del, dynamic isinstance, tuple-iteration types, typed class field access, cls(**kwargs) MRO walk in @classmethod
• PCC-emitted Python runtime modules — tuple, exc_tls, traceback, dunder, obj_stubs, os_substrate; libpy_runtime.a no longer checked in (built via pcc itself at install time)
• Build / packaging — pip install runs the runtime build via pcc, defaults to --backend self
• Docs — GC semantics gap plan, data-model gaps plan, native stdlib plans, self-host ergonomics; six doc files translated from Chinese to English

Install

pip install python-cc==0.1.1

pcc 0.1.0

Highlights

• Python frontend self-host bootstrap (#138.1–#138.5) — comprehensive feature coverage: comprehensions, kwargs, walrus, generator expressions, dataclass fields, cls(...) in @classmethod, CPython fallback for imported names, and a large builtins/str-methods parity set
• SSA MidTier — SCCP, GVN, ADCE + rewrite passes feeding AST, with direct SSA→LLVM lowering
• Pass framework — HighTier / MidTier / LowTier pipeline, 80/80 LLVM leaf passes mapped
• Python API — pcc.module() / pcc.build() one-line compile-to-callable
• Benchmarks & differential testing — csmith fuzz harness, 80-case microbenchmark suite, pcc -O2 at parity with clang -O2 runtime
• Multi-file compile spike — native cross-module imports without libpython link, shared cross-module type registry
• Linux aarch64 support

Install
