Aligns with llvm::coverage::CounterMappingRegion::RegionKind

Variants

CodeRegion

A CodeRegion associates some code with a counter

ExpansionRegion

An ExpansionRegion represents a file expansion region that associates a source range with the expansion of a virtual source file, such as for a macro instantiation or #include file.

SkippedRegion

A SkippedRegion represents a source range with code that was skipped by a preprocessor or similar means.

GapRegion

A GapRegion is like a CodeRegion, but its count is only set as the line execution count when its the only region in the line.

BranchRegion

A BranchRegion represents leaf-level boolean expressions and is associated with two counters, each representing the number of times the expression evaluates to true or false.
