Method clear

cranelift/codegen/src/loop_analysis.rs:187–191

Clear all the data structures contained in the loop analysis. This will leave the analysis in a similar state to a context returned by `new()` except that allocated memory be retained.

(&mut self)

    /// analysis in a similar state to a context returned by `new()` except that allocated
    /// memory be retained.
    pub fn clear(&mut self) {
        self.loops.clear();
        self.block_loop_map.clear();
        self.valid = false;
    }

    // Determines if a block dominates any predecessor
    // and thus is a loop header.
