Differences

Changed linker behavior

The following changes have been made to the linker behavior:

• The linker accepts symbol definitions in a file. These symbols can provide global

symbol values for a previously generated image file.

• If a scatter-loading file is used with the linker, output section symbols such as

Image$$RW$$Limit

are not defined.

Note

If you are using scatter-loading files as input to the linker, you must reimplement

__user_initial_stackheap()

to set the heap and stack boundaries. If you do not

have a reimplementation of this function, the following error message is

displayed:

Error: L6218E: Undefined symbol Image$$ZI$$Limit (referred from

sys_stackheap.o).

New linker options

The following linker options are new for ADS 1.2:

-reloc

Produces relocatable images.

-match crossmangled

This option instructs the linker to match between mangled and

unmangled definitions in either source code or libraries.

2.2.6 Changes to armar and fromELF

This section describes:

• New armar behavior

• New fromELF options on page 2-10.

New armar behavior

The following behavior is new to ADS 1.2:

• Libraries can be merged together into a new library. If one or more of the files in

the input list is a library, armar copies all members from the input library to the

destination library. The order of entries on the command line is preserved.
