+@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)
+@end smallexample

@node FR-V Built-in Functions
@subsection FR-V Built-in Functions
Don't generate extra code to prevent speculative loads from occurring.
@item -mcsync-anomaly
-@opindex mspecld-anomaly
+@opindex mcsync-anomaly
When enabled, the compiler will ensure that the generated code does not
contain CSYNC or SSYNC instructions too soon after conditional branches.
This option is enabled by default.
@item -mno-csync-anomaly
-@opindex mno-specld-anomaly
+@opindex mno-csync-anomaly
Don't generate extra code to prevent CSYNC or SSYNC instructions from
occurring too soon after a conditional branch.
