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 Concurrency 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.
