getFilename()

static SmallString< 128 > getFilename ( const DISubprogram *  SP )

Extract a filename for a DISubprogram.

Prefer relative paths in the coverage notes. Clang also may split up absolute paths into a directory and filename component. When the relative path doesn't exist, reconstruct the absolute path.
