Module rustc_codegen_llvm::coverageinfo::mapgen

Structs

• CoverageMapGenerator 🔒

Functions

• add_unused_functions 🔒
  When finalizing the coverage map, FunctionCoverage only has the CodeRegions and counters for the functions that went through codegen; such as public functions and “used” functions (functions referenced by other “used” or public items). Any other functions considered unused, or “Unreachable”, were still parsed and processed through the MIR stage, but were not codegenned. (Note that -Clink-dead-code can force some unused code to be codegenned, but that flag is known to cause other errors, when combined with -C instrument-coverage; and -Clink-dead-code will not generate code for unused generic functions.)
• finalize
  Generates and exports the Coverage Map.
• save_function_record 🔒
  Construct a function record and combine it with the function’s coverage mapping data. Save the function record into the LLVM IR as a static global using a specific, well-known section and name.
