Specify Blocking for an Initialized Section
.sblock
4-77
Assembler Directives
Syntax
.sblock [”]
section name[”] [, ”section name”, . . . ]
Description
The .sblock directive designates sections for blocking. Blocking is an address
alignment mechanism similar to page alignment, but weaker. A blocked
section is guaranteed to not cross a page boundary (128 words) if it is smaller
than a page, or to start on a page boundary if it is larger than a page. This direc-
tive allows specification of blocking for initialized sections only, not uninitialized
sections declared with .usect or the .bss directives. The
section names may
optionally be enclosed in quotes.
Example
This example designates the .text and .data sections for blocking.
