Variants

Declined

The function declines for a reason INDEPENDENT of composition (an unproven loop, an internal looped expansion, an unsupported core, an unresolved label branch, an indirect call, or an unmodeled op). Carried straight through to a WcetFunction::Declined; composition never rescues these.

Fields

site: Option<WcetDeclineSite>

(#921) The op that caused the decline, when it names one.

name: String

reason: WcetDecline

hint_rejections: Vec<WcetHintRejection>

Composable

The function’s own body is bounded; its final bound depends only on resolving the recorded direct call sites against the module’s other functions.

Fields

name: String

own_cycles: u64

The summed worst-case cost of every instruction in the final stream (each priced at its documented worst case × its proven execution-count multiplier), INCLUDING each direct BL’s branch overhead. The callee bodies are added by the composer via call_sites.

instr_count: usize

Number of ARM instructions summed (diagnostic, carried to the bound).

call_sites: Vec<WcetCallSite>

The direct call sites to resolve at compose time.

loops: Vec<WcetLoopBound>

Proven loops inside this function (carried to the bound unchanged).

recursion_cert: Option<WcetRecursionCert>

(#778 phase 4 / #49) A proven self-recursion certificate, when this function is a bounded single-self-call chain with a verified depth hint. The composer folds the self-edge as (max_depth+1) × frame_cost instead of declining Recursion. None for a non-recursive function or an unverifiable/unhinted recursion (which still declines).

hint_rejections: Vec<WcetHintRejection>

Hints rejected while analyzing this function (carried to the bound).
