Module rustc_mir::transform::coverage::query

Structs

CoverageVisitor

The num_counters argument to llvm.instrprof.increment is the max counter_id + 1, or in other words, the number of counter value references injected into the MIR (plus 1 for the reserved ZERO counter, which uses counter ID 0 when included in an expression). Injected counters have a counter ID from 1..num_counters-1.

Functions

coverageinfo_from_mir
covered_code_regions
covered_file_name
provide	The query provider for CoverageInfo, requested by codegen_coverage() (to inject each counter) and FunctionCoverage::new() (to extract the coverage map metadata from the MIR).
