Migrating Projects from SDT to ADS

to:

basesym SETS "|Image$$$$":CC:namecp:CC:"$$$$Base|"

See Changed assembler behavior on page 2-52, and the ADS Assembler Guide for more

information.

Note

In ADS, RO/RW/ZI initialization is usually done by the C library. You might not need

your SDT initialization code. See Initialization of C Libraries and Execution Regions

on page 4-13 for more information.

4.2.3 Linking

Some linker features have changed between SDT and ADS. For a full list of changes

between SDT and ADS 1.0, see Chapter 2 Differences. The following sections describe

changes that most frequently cause problems when moving to ADS:

• Specifying libraries

• Change -info size to -info sizes on page 4-9

• Change -symbols file to -symbols on page 4-9

• Linking old objects on page 4-9

• Linking old libraries on page 4-10

• Unused section elimination on page 4-10

• Use of +RW and +ZI in scatter-loading on page 4-11

• Generating binary images on page 4-13.

• Section naming in scatter-loading on page 4-13

Specifying libraries

With SDT, it is common to specify C libraries on the linker command line, in particular

if you are using the Embedded C libraries.

With ADS:

• There are no Embedded C libraries supplied with ADS. You can retarget the

standard C libraries for embedded use. See the description of tailoring the C

library to a new execution environment in the ADS Compilers and Libraries

Guide for detailed information.

• The names of the C libraries are different to those used for SDT. See the

description of library naming conventions in the ADS Compilers and Libraries

Guide.
