Intel-Specific Pragma Reference
Pragmas specific to the
Intel® oneAPI
are listed in the following table.
DPC++/C++
Compiler Most Intel-specific pragmas support host code only unless otherwise noted.
Some
pragmas
are available for both Intel® microprocessors and non-Intel microprocessors, but may perform additional optimizations for Intel® microprocessors than for non-Intel microprocessors.
Pragma
| Description
|
|---|---|
Enables or disables
loop blocking for the immediately following nested loops. block_loop enables
loop blocking for the nested loops. noblock_loop disables loop blocking for the
nested loops. | |
Instructs the compiler
to prefer loop distribution at the location indicated. | |
Specifies inlining of
all calls in a statement. This also describes pragmas forceinline and
noinline. | |
Instructs the compiler
to ignore assumed vector dependencies. | |
Specifies the
iterations for a for loop. | |
Prevents a loop from fusing with adjacent loops. | |
Specifies that a
particular loop should never be vectorized. | |
Conditionally calls a
procedure offload variant if the specified device is available; otherwise,
executes the procedure on the host.
| |
Invites the compiler
to issue or disable requests to prefetch data from memory. This pragma applies
only to Intel® Advanced Vector Extensions 512 (Intel® AVX-512).
| |
Tells the compiler to
unroll or not to unroll a counted loop. | |
Enables or disables
loop unrolling and jamming. These pragmas can only be applied to iterative for
loops. | |
Tells the compiler
that the loop should be vectorized according to the argument keywords.
