Arguments

keyword

Specifies whether streaming stores are generated. Possible values are:

always	Enables generation of streaming stores for optimization. The compiler optimizes under the assumption that the application is memory bound.
never	Disables generation of streaming stores for optimization. Normal stores are performed.
auto	Lets the compiler decide which instructions to use.

Default

-opt-streaming-stores auto
or/Qopt-streaming-stores:auto

The compiler decides whether to use streaming stores or normal stores.

Description

This option enables generation of streaming stores for optimization. This method stores data with instructions that use a non-temporal buffer, which minimizes memory hierarchy pollution.

This option may be useful for applications that can benefit from streaming stores.
