@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

When enabled, the compiler will ensure that the generated code does not
contain CSYNC or SSYNC instructions too soon after conditional branches.
