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);
StringRef Dir = Scope.getDirectory(),
Filename = Scope.getFilename();
char *&Result = DirAndFilenameToFilepathMap[std::make_pair(Dir, Filename)];
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;
if (Filename.find(':') == 1)
Filepath = Filename;
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.
std::replace(Filepath.begin(), Filepath.end(), '/', '\\');
// Remove all "\.\" with "\".
size_t Cursor = 0;
while ((Cursor = Filepath.find("\\.\\", Cursor)) != std::string::npos)
Filepath.erase(Cursor, 2);
// Replace all "\XXX\..\" with "\". Don't try too hard though as the original
// path should be well-formatted, e.g. start with a drive letter, etc.
Cursor = 0;
while ((Cursor = Filepath.find("\\..\\", Cursor)) != std::string::npos) {
// Something's wrong if the path starts with "\..\", abort.

}示例2: printDebugLoc
static void printDebugLoc(DebugLoc DL, raw_ostream &CommentOS,
const LLVMContext &Ctx) {
if (!DL)
return;
DIScope Scope = cast<MDScope>(DL.getScope());
// Omit the directory, because it's likely to be long and uninteresting.
CommentOS << Scope.getFilename();

const char *LLVMGetFileName(LLVMValueRef Scope)
{
DIScope S = unwrapDI<DIScope>(Scope);
StringRef str = S.getFilename();
return str.data();
