示例1: getFullFilepath
StringRef WinCodeViewLineTables::getFullFilepath(const MDNode *S) {
assert(S);
assert((isa<MDCompileUnit>(S) || isa<MDFile>(S) || isa<MDSubprogram>(S) ||
isa<MDLexicalBlockBase>(S)) &&
"Unexpected scope info");
DIScope Scope = cast<MDScope>(S);

if (Result)
return Result;
// Clang emits directory and relative filename info into the IR, but CodeView
// operates on full paths. We could change Clang to emit full paths too, but
// that would increase the IR size and probably not needed for other users.
// For now, just concatenate and canonicalize the path here.
std::string Filepath;

else
Filepath = (Dir + "\\" + Filename).str();
// Canonicalize the path. We have to do it textually because we may no longer
// have access the file in the filesystem.
// First, replace all slashes with backslashes.

// Remove all "\.\" with "\".
size_t Cursor = 0;

// path should be well-formatted, e.g. start with a drive letter, etc.
