Member Enumeration Documentation

◆ CondState

CondState represents the evaluation of a condition in an executed test vector, which can be True or False.

A DontCare is used to mask an unevaluatable condition resulting from short-circuit behavior of logical operators in languages like C/C++. When comparing the evaluation of a condition across executed test vectors, comparisons against a DontCare are effectively ignored.

Member Function Documentation

◆ getConditionCoverageString()

std::string llvm::coverage::MCDCRecord::getConditionCoverageString ( unsigned  Condition)
inline

◆ getConditionHeaderString()

std::string llvm::coverage::MCDCRecord::getConditionHeaderString ( unsigned  Condition)
inline

References OS.

◆ getConditionIndependencePair()

TVRowPair llvm::coverage::MCDCRecord::getConditionIndependencePair ( unsigned  Condition)
inline

Return the Independence Pair that covers the given condition.

Because condition IDs are not associated based on their position in the expression, accessing conditions in the TestVectors requires a translation from a ordinal position to actual condition ID. This is done via PosToID[].

◆ getTVCondition()

CondState llvm::coverage::MCDCRecord::getTVCondition ( unsigned  TestVectorIndex,

inline

Return the evaluation of a condition (indicated by Condition) in an executed test vector (indicated by TestVectorIndex), which will be True, False, or DontCare if the condition is unevaluatable.

Because condition IDs are not associated based on their position in the expression, accessing conditions in the TestVectors requires a translation from a ordinal position to actual condition ID. This is done via PosToID[].

CondState llvm::coverage::MCDCRecord::getTVResult ( unsigned  TestVectorIndex)

Return the Result evaluation for an executed test vector.

Determine whether a given condition (indicated by Condition) is covered by an Independence Pair.
