But this will be an important edge case when adding expansion region support. coverage: Add LLVM plumbing for expansion regions 2025-03-20T01:40:36+00:00 Zalathar Zalathar@users.noreply.github.com 2025-03-04T10:55:43+00:00 urn:sha1:d07ef5b0e1f7551ad24f86256d63a5dfdb907c17 This is currently unused, but paves the way for future work on expansion regions without having to worry about the FFI parts. coverage: Store coverage source regions as `Span` until codegen 2024-12-19T07:09:09+00:00 Zalathar Zalathar@users.noreply.github.com 2024-12-18T10:00:51+00:00 urn:sha1:34ed51cb837d1dd755b9b97798a41c8cd0358ca6 coverage: Rename some FFI fields from `span` to `cov_span` 2024-12-19T06:26:01+00:00 Zalathar Zalathar@users.noreply.github.com 2024-12-18T07:59:27+00:00 urn:sha1:d416cead5a92d6a054d0e4d18a4b3a965f35334d This will avoid confusion with actual `Span` spans. coverage: Store intermediate region tables in `CovfunRecord` 2024-12-11T10:35:45+00:00 Zalathar Zalathar@users.noreply.github.com 2024-12-11T04:41:02+00:00 urn:sha1:3f3a9bf7f50afbfde72cd0b9479323dddc84fe6d This defers the call to `llvm_cov::write_function_mappings_to_buffer` until just before its enclosing global variable is created.
