NAME
ck_pr_fence_load_depends — data dependency barrier
LIBRARY
Concurrency Kit (libck, -lck)
SYNOPSIS
#include <ck_pr.h>
void
ck_pr_fence_load_depends(void);
DESCRIPTION
The ck_pr_fence_load_depends(3) emits necessary fences for pure data-
dependent loads. It currently only serves as a compiler barrier for Con‐
currency Kit's supported platforms. Unless you're on architecture which
re-orders data-dependent loads (such as the defunct Alpha), this function
is unnecessary.
RETURN VALUES
This function has no return value.
