Member Function Documentation

◆ AddEntry()

void LineTableInfo::AddEntry ( FileID  FID,
const std::vector< LineEntry > &  Entries 
)

Add a new line entry that has already been encoded into the internal representation of the line table.

Definition at line 262 of file SourceManager.cpp.

◆ AddLineNote()

void LineTableInfo::AddLineNote ( FileID  FID,
unsigned  Offset,
unsigned  LineNo,
int  FilenameID,
unsigned  EntryExit,
SrcMgr::CharacteristicKind  FileKind 
)

Add a line note to the line table that indicates that there is a #line or GNU line marker at the specified FID/Offset location which changes the presumed location to LineNo/FilenameID.

If EntryExit is 0, then this doesn't change the presumed #include stack. If it is 1, this is a file entry, if it is 2 then this is a file exit. FileKind specifies whether this is a system header or extern C system header.

◆ FindNearestLineEntry()

const LineEntry * LineTableInfo::FindNearestLineEntry ( FileID  FID,
unsigned  Offset 
)

Find the line entry nearest to FID that is before it.

FindNearestLineEntry - Find the line entry nearest to FID that is before it.

If there is no line entry before Offset in FID, returns null.

If there is no line entry before Offset in FID, return null.
