◆ checkLocForMacroArgExpansion()

static bool checkLocForMacroArgExpansion ( SourceLocation  Loc,
const SourceManager SM,
SourceLocation  ArgumentLoc 
)
static

Check that the macro argument location of Loc starts with ArgumentLoc.

The starting location of the macro expansions is used to differeniate different macro expansions.

◆ checkRangeForMacroArgExpansion()

static bool checkRangeForMacroArgExpansion ( CharSourceRange  Range,
const SourceManager SM,
SourceLocation  ArgumentLoc 
)
static

Check if all the locations in the range have the same macro argument expansion, and that that expansion starts with ArgumentLoc.

◆ checkRangesForMacroArgExpansion()

static bool checkRangesForMacroArgExpansion ( FullSourceLoc  Loc,
ArrayRef< CharSourceRange Ranges 
)
static

A helper function to check if the current ranges are all inside the same macro argument expansion as Loc.

Count all valid ranges.

To store the source location of the argument location.

Set the ArgumentLoc to the beginning location of the expansion of Loc so to check if the ranges expands to the same beginning location.

Collect the expansions of the begin and end locations and compute the set intersection.

Produces a sorted vector of FileIDs in CommonArgExpansions.
