Module rustc_mir_transform::coverage

Modules

• counters 🔒
• graph 🔒
• query
• spans 🔒

Structs

• ExtractedHirInfo 🔒
  Function information extracted from HIR by the coverage instrumentor.
• InstrumentCoverage
  Inserts StatementKind::Coverage statements that either instrument the binary with injected counters, via intrinsic llvm.instrprof.increment, and/or inject metadata used during codegen to construct the coverage map.

Functions

• check_code_region 🔒
  If llvm-cov sees a code region that is improperly ordered (end < start), it will immediately exit with a fatal error. To prevent that from happening, discard regions that are improperly ordered, or might be interpreted in a way that makes them improperly ordered.
• create_mappings 🔒
  For each coverage span extracted from MIR, create a corresponding mapping.
• extract_hir_info 🔒
• get_body_span 🔒
• hash_mir_source 🔒
• inject_coverage_statements 🔒
  For each BCB node or BCB edge that has an associated coverage counter, inject any necessary coverage statements into MIR.
• inject_edge_counter_basic_block 🔒
• inject_statement 🔒
• instrument_function_for_coverage 🔒
• is_eligible_for_coverage 🔒
• make_code_region 🔒
  Convert the Span into its file name, start line and column, and end line and column.
• make_mir_coverage_kind 🔒
