Modules

• ffi 🔒
• map_data 🔒
• mapgen

Structs

• CrateCoverageContext
  A context object for maintaining all state needed by the coverageinfo module.

Constants

• UNUSED_FUNCTION_COUNTER_ID 🔒
• VAR_ALIGN_BYTES 🔒

Functions

• add_unused_function_coverage 🔒
• codegen_unused_fn_and_counter 🔒
• covfun_section_name 🔒
  Returns the section name string to pass through to the linker when embedding per-function coverage information in the object file, according to the target platform’s object file format.
• create_pgo_func_name_var 🔒
  Calls llvm::createPGOFuncNameVar() with the given function instance’s mangled function name. The LLVM API returns an llvm::GlobalVariable containing the function name, with the specific variable name and linkage required by LLVM InstrProf source-based coverage instrumentation. Use bx.get_pgo_func_name_var() to ensure the variable is only created once per Instance.
