Implementations§

source§

impl<'a, 'tcx> CfgSimplifier<'a, 'tcx>

source

pub fn new(body: &'a mut Body<'tcx>) -> Self

source

pub fn simplify(self)

source

fn take_terminator_if_simple_goto( &mut self, bb: BasicBlock ) -> Option<Terminator<'tcx>>

This function will return None if

  • the block has statements
  • the block has a terminator other than goto
  • the block has no terminator (meaning some other part of the current optimization stole it)
source

fn collapse_goto_chain(&mut self, start: &mut BasicBlock, changed: &mut bool)

Collapse a goto chain starting from start
