Struct rustc_middle::mir::query::CoverageIdsInfo

source ·

pub struct CoverageIdsInfo {
    pub max_counter_id: CounterId,
    pub mcdc_bitmap_bytes: u32,
}

Expand description

Summarizes coverage IDs inserted by the InstrumentCoverage MIR pass (for compiler option -Cinstrument-coverage), after MIR optimizations have had a chance to potentially remove some of them.

Used by the coverage_ids_info query.

Fields§

§max_counter_id: CounterId

Coverage codegen needs to know the highest counter ID that is ever incremented within a function, so that it can set the num-counters argument of the llvm.instrprof.increment intrinsic.

This may be less than the highest counter ID emitted by the InstrumentCoverage MIR pass, if the highest-numbered counter increments were removed by MIR optimizations.

§mcdc_bitmap_bytes: u32

Coverage codegen for mcdc needs to know the size of the global bitmap so that it can set the bytemap-bytes argument of the llvm.instrprof.mcdc.tvbitmap.update intrinsic.
