Description Sven Neumann 2008-09-13 11:26:25 UTC 
C99 introduces the keyword restrict that allows developers to tell the compiler that pointers which share the same type do not alias each other. GCC allows to use this keyword even in C89 mode as __restrict__. It would be nice if GLib could wrap this into G_GNUC_RESTRICT so that it can be used without introducing a dependency on GCC.

Out of interest, what do you want to use restrict for ?
Comment 3 Sven Neumann 2008-09-16 06:23:27 UTC 
Someone expressed his interest to use restrict in GEGL as a means to allow the compiler to create faster code. It appeared to me that it might be of interest for other users of GLib.
