4.7.33.  __schedule_barrier

This intrinsic creates a sequence point where operations before and operations after the sequence point are not merged by the compiler. A scheduling barrier does not cause memory to be updated. If variables are held in registers they are updated in place, and not written out.

This intrinsic is similar to the __nop intrinsic, except that no NOP instruction is generated.

Syntax

void schedule_barrier(void)
