     True  False DontCare (Impossible)

Values: True False False True Visited: True True False False

Constructor & Destructor Documentation

◆ TestVector()

llvm::coverage::MCDCRecord::TestVector::TestVector ( unsigned  N)


Default values are filled with DontCare.

◆ getDifferences()

auto llvm::coverage::MCDCRecord::TestVector::getDifferences ( const TestVector B) const

For each element:

  • False if either is DontCare
  • False if both have the same value
  • True if both have the opposite value ((A.Values ^ B.Values) & A.Visited & B.Visited) Dedicated to findIndependencePairs().

Definition at line 429 of file CoverageMapping.h.

References A, and B.

◆ getIndex()

auto llvm::coverage::MCDCRecord::TestVector::getIndex ( ) const

Equivalent to buildTestVector's Index.

Definition at line 407 of file CoverageMapping.h.

References llvm::BitVector::getData().

◆ operator[]()

CondState llvm::coverage::MCDCRecord::TestVector::operator[] ( int  I) const

◆ push_back()

void llvm::coverage::MCDCRecord::TestVector::push_back ( CondState  Val)

◆ set()

void llvm::coverage::MCDCRecord::TestVector::set ( int  I,
CondState  Val 

Set the condition Val at position I.

This emulates LHS SmallVector::operator[].
