closes #60 The fixture-corpus filter (NON_PARSEABLE_FIXTURES + list_ail_fixtures) was copy-pasted across three test crates and drifted out of sync as new reject fixtures landed; the examples_dir / workspace_root path walk was reimplemented ~30 more times across the suite, under two spellings (workspace_root / ws_root). Introduce crates/ailang-test-support — a zero-dependency, dev-only leaf crate — as the single home for these helpers: - NON_PARSEABLE_FIXTURES, list_ail_fixtures - workspace_root, examples_dir - canonical_workspace_root (symlink-resolved variant, for the tsan/ race tests that feed the root into native build steps) All integration-test copies across ailang-core, ailang-surface, ailang-prose, ailang-check, and ail now import from the shared crate; the local definitions and their now-orphaned path imports are removed. Path helpers resolve via the support crate's own CARGO_MANIFEST_DIR, so they return the correct absolute paths from any caller. ail_bin helpers are intentionally left in place: they depend on env!("CARGO_BIN_EXE_ail"), which Cargo only defines when compiling the ail crate's own integration tests, so they cannot move to a shared crate. Behaviour-identical: same paths, same fixture lists; full workspace test suite green. Net -177 LOC.

//! Floats milestone iter 4.6 — end-to-end fixture.
|
|
//!
|
|
//! `examples/floats.ail.json` is built via the public `ail build`
|
|
//! CLI and run; stdout is matched against the expected three
|
|
//! lines (`4.0`, `42.0`, `-1.5`). This test exercises the full
|
|
//! pipeline — Float literal lowering, polymorphic `+` Float arm,
|
|
//! `int_to_float` (sitofp), `neg` Float (fneg), and the polymorphic
|
|
//! `print` for Float (routes through `Show Float.show` →
|
|
//! `float_to_str`, libc `%g` plus the runtime `.0`-fallback for
|
|
//! whole-valued Float results, per Gitea #7).
