Function rustc_codegen_llvm::coverageinfo::mapgen::save_function_record

fn save_function_record(
    cx: &CodegenCx<'_, '_>,
    covfun_section_name: &str,
    mangled_function_name: &str,

)

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.
