Marks a block with a scope-unique identifier.
where:
n Is an integer expression the size of the iteration group. name_list Is a unique identifier you can create using the #pragma loopid directive. If you do not specify name, blocking occurs on the first for loop following the #pragma block_loop directive.
name is an identifier that is unique within the scoping unit.
For loop blocking to occur, a #pragma blockloop directive must precede a for loop.
You must not specify #pragma blockloop more than once, or combine the directive with the nounroll, unroll, nounrollandfuse, unrollandfuse, or stream_unroll #pragma directives for the same for loop.
You must not specify #pragma blockloop more than once for a given loop.
