Blackfin Built-in Functions (Using the GNU Compiler Collection (GCC))

#### 7.13.9 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);
