+@subsection Blackfin Built-in Functions
+
+Currently, there are two Blackfin-specific built-in functions.  These are
+used for generating @code{CSYNC} and @code{SSYNC} machine insns without
+using inline assembly; by using these built-in functions the compiler can
+automatically add workarounds for hardware errata involving these
+instructions.  These functions are named as follows:
+
+@smallexample
+void __builtin_bfin_csync (void)
+void __builtin_bfin_ssync (void)

 contain CSYNC or SSYNC instructions too soon after conditional branches.
