Hi, it seems overloading on __restrict__ is not possible. I.e. GCC complains about: void foo(float *__restrict__ mem) const; void foo(float *mem) const; This, to me, seems to have a very valid use case. Also the AIX C++ compiler docs ( http://publib.boulder.ibm.com/infocenter/comphelp/v7v91/index.jsp?topic=%2Fcom.ibm.vacpp7a.doc%2Flanguage%2Fref%2Fclrc03restrict_type_qualifier.htm) specify "The __restrict__ qualifier also affects parameter type specifications for overloaded functions in the same way as a cv-qualifier, thereby affecting the overload set." In the GCC docs I couldn't find a statement either way. Was it a deliberate decision to not allow overloading on __restrict__? (I have to use -fabi- version=4 anyway, so I don't care much if it would require a new ABI version.) Regards, Matthias -- Dipl.-Phys. Matthias Kretz http://compeng.uni-frankfurt.de/?mkretz
