source · [−]
Expand description

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.
