Module rustc_mir_transform::const_prop

Propagates constants for early reporting of statically known assertion failures

Macros

• throw_machine_stop_str 🔒
  Macro for machine-specific InterpError without allocation. (These will never be shown to the user, but they help diagnose ICEs.)

Structs

• CanConstProp
• ConstProp
• ConstPropMachine
• ConstPropagator 🔒
  Finds optimization opportunities on the MIR.

Enums

• ConstPropMode
  The mode that ConstProp is allowed to run in for a given Local.

Constants

• MAX_ALLOC_LIMIT 🔒
  The maximum number of bytes that we’ll allocate space for a local or the return value. Needed for #66397, because otherwise we eval into large places and that can cause OOM or just Severely regress performance.
