[cfe-dev] Confused about SourceLocs

[Nico Weber]

Hi all,

is it correct that both the logical and the physical location of a  
macro SourceLoc are always file SourceLocs?

Just out of curiosity: Does clang in any way store which macro calls  
which other macros?

Finally, the attached patch adds some functions to FullSourceLocation  
that are useful in my eyes. It also modifies isValidMacroPhysOffs() to  
use the complete range of a two's complement integer.

Nico
