Copy most of `tests/run-coverage` into `tests/coverage-map/status-quo` The output of these tests is too complicated to comfortably verify by hand, but we can still use them to observe changes to the underlying mappings produced by codegen/LLVM. If these tests fail due to non-coverage changes (e.g. in HIR-to-MIR lowering or MIR optimizations), it should usually be OK to just `--bless` them, as long as the `run-coverage` test suite still works. 2023-08-14 11:29:41 +00:00			`Function name: test_harness::my_test`

coverage: Mappings for unused functions can all be zero There is no need to include a dummy counter reference in the coverage mappings for an unused function. 2023-09-07 09:58:11 +00:00			`Raw bytes (9): 0x[01, 01, 00, 01, 00, 07, 01, 00, 0f]`
