Expand description
We import passes via this macro so that we can have a static list of pass names (used to verify CLI arguments). It takes a list of modules, followed by the passes declared within them.

declare_passes! {
// Declare a single pass from the module `abort_unwinding_calls`
mod abort_unwinding_calls : AbortUnwindingCalls;
// When passes are grouped together as an enum, declare the two constituent passes
mod add_call_guards : AddCallGuards {
AllCallEdges,
CriticalCallEdges
};
// Declares multiple pass groups, each containing their own constituent passes
mod simplify : SimplifyCfg {
Initial,
/* omitted */
}, SimplifyLocals {
BeforeConstProp,
/* omitted */
};
