@cindex region alias

@cindex region names

Alias names can be added to existing memory regions created with the

@smallexample
|

REGION_ALIAS(@var{alias}, @var{region})
|
||||
@end smallexample
|
||||
|
||||
The @code{REGION_ALIAS} function creates an alias name @var{alias} for the
|
||||
memory region @var{region}. This allows a flexible mapping of output sections
|
||||
to memory regions. An example follows.
|
||||
|
||||
Suppose we have an application for embedded systems which come with various
|
||||
memory storage devices. All have a general purpose, volatile memory @code{RAM}
|
||||
that allows code execution or data storage. Some may have a read-only,
|
||||
non-volatile memory @code{ROM} that allows code execution and read-only data
|
||||
access. The last variant is a read-only, non-volatile memory @code{ROM2} with
|
||||
read-only data access and no code execution capability. We have four output
|
||||
sections:
|
||||
|
||||
@itemize @bullet
|
||||
@item
|
||||
@code{.text} program code;
|
||||
@item
|
||||
@code{.rodata} read-only data;
|
||||
@item
|
||||
@code{.data} read-write initialized data;
|
||||
@item
|
||||
@code{.bss} read-write zero initialized data.
|
||||
@end itemize
|
||||
|
||||
The goal is to provide a linker command file that contains a system independent
|
||||
part defining the output sections and a system dependent part mapping the
|
||||
output sections to the memory regions available on the system. Our embedded
|
||||
systems come with three different memory setups @code{A}, @code{B} and
|
||||
@code{C}:
|
||||
@multitable @columnfractions .25 .25 .25 .25
|
||||
@item Section @tab Variant A @tab Variant B @tab Variant C
|
||||
@item .text @tab RAM @tab ROM @tab ROM
|
||||
@item .rodata @tab RAM @tab ROM @tab ROM2
|
||||
@item .data @tab RAM @tab RAM/ROM @tab RAM/ROM2
|
||||
@item .bss @tab RAM @tab RAM @tab RAM
|
||||
@end multitable
|
||||
The notation @code{RAM/ROM} or @code{RAM/ROM2} means that this section is
|
||||
loaded into region @code{ROM} or @code{ROM2} respectively. Please note that
|
||||
the load address of the @code{.data} section starts in all three variants at
|
||||
the end of the @code{.rodata} section.
|
||||
|
||||
The base linker script that deals with the output sections follows. It
|
||||
includes the system dependent @code{linkcmds.memory} file that describes the
|
||||
memory layout:
|
||||
@smallexample
|
||||
INCLUDE linkcmds.memory
|
||||
|
||||

||||

|
||||

Now we need three different @code{linkcmds.memory} files to define memory
|
||||
regions and alias names. The content of @code{linkcmds.memory} for the three
|
||||
variants @code{A}, @code{B} and @code{C}:
|
