• Changes to the assembler on page 2-7

• Changes to the linker on page 2-8

• Changes to armar and fromELF on page 2-9

• Changes to the debuggers on page 2-10

• Changes to the ARMulator on page 2-10

• Changes to the CodeWarrior IDE on page 2-11

• Changes to the examples on page 2-11

• Changes to the documentation on page 2-11.

2.2.1 Differences in default behavior

This section gives a summary of the changed default behavior.

Image$$RW$$Limit

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

Image$$RW$$Limit

and

Image$$ZI$$Limit

are not defined. (In earlier versions of ADS,

output section symbols had a default value of zero when used with scatter loading and

linker error messages were not generated.)

Impact

If you are using scatter-loading with the linker, you must reimplement the

__user_initial_stackheap()

function to set the heap and stack boundaries. The default

implementation uses

Image$$ZI$$Limit

to identify the top of used RW/ZI memory. See

the section on libraries in the ADS Compilers and Libraries Guide.

2.2.2 Functionality enhancements and new functionality

This section gives a summary of the major functionality enhancements in ADS 1.2. See

the sections for the individual tools for a more detailed description of changes and

enhancements for each component of ADS.
