Blackfin Built-in Functions

Currently, there are two Blackfin-specific built-in functions. These are used for generating CSYNC and 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:

     void __builtin_bfin_csync (void)

     void __builtin_bfin_ssync (void)
