+These built-in functions are available for the Alpha family of
+processors, depending on the command-line switches used.
+
+The following built-in functions are always available.  They 
+all generate the machine instruction that is part of the name.

+@example

+long __builtin_alpha_rpcc (void)
+long __builtin_alpha_amask (long)
+long __builtin_alpha_cmpbge (long, long)

+long __builtin_alpha_zap (long, long)
+long __builtin_alpha_zapnot (long, long)
+@end example
+
+The following built-in functions are always with @option{-mmax}
+or @option{-mcpu=@var{cpu}} where @var{cpu} is @code{pca56} or
+later.  They all generate the machine instruction that is part
+of the name.
