Zalathar	f5df56b26b	coverage: Flatten coverage-map/status-quo/ into its parent directory	2023-11-07 11:15:18 +11:00
Zalathar	8eef39f082	coverage: Remove tests/coverage-map/if.rs ... There is another test named `if.rs` in `tests/coverage-map/status-quo/`, so this test stands in the way of flattening that directory into its parent. Fortunately both tests are more-or-less equivalent, so removing this one is fine.	2023-11-07 11:15:18 +11:00
Zalathar	004db4728b	Add test suite coverage-map to test coverage mappings emitted by LLVM ... We compile each test file to LLVM IR assembly, and then pass that IR to a dedicated program that can decode LLVM coverage maps and print them in a more human-readable format. We can then check that output against known-good snapshots. This test suite has some advantages over the existing `run-coverage` tests: - We can test coverage instrumentation without needing to run target binaries. - We can observe subtle improvements/regressions in the underlying coverage mappings that don't make a visible difference to coverage reports.	2023-09-05 11:55:17 +10:00
