In practice, the ``SourceLocation`` works together with the ``SourceManager``
class to encode two pieces of information about a location: its spelling
location and its instantiation location. For most tokens, these will be the
location and its expansion location. For most tokens, these will be the
same. However, for a macro expansion (or tokens that came from a ``_Pragma``
directive) these will describe the location of the characters corresponding to
the token and the location where the token was used (i.e., the macro
instantiation point or the location of the ``_Pragma`` itself).
expansion point or the location of the ``_Pragma`` itself).
The Clang front-end inherently depends on the location of a token being tracked
correctly. If it is ever incorrect, the front-end may get confused and die.
