Differences

Impact

You must modify existing makefiles that use these options.

Changed behavior

ADS 1.1 introduces the following changes to the behavior of the assembler:

• The assembler now faults a call to a

GET

directive from within a macro.

• The assembler now faults the use of built-in variable names or predefined symbol

names as a user symbol, such as a macro name. In ADS 1.0 the assembler silently

ignored such usage.

• The assembler is now much stricter and more consistent in faulting usage that

does not conform to the ARM Architecture Reference manual. For example:

CMP ip,a3,ASL #0

; Generates Warning: A1484E: Obsolete shift name ‘ASL’, use LSL instead

and:

SWP r0,r1,[r0]

; Generates Warning: A1477W: This register combination results

; in UNPREDICTABLE behavior

2.3.5 Changes to the linker

This section describes:

• New linker options

• Changed linker behavior on page 2-26.

New linker options

This section gives a brief summary of new linker options for ADS 1.1. Refer to the ADS

Linker and Utilities Guide for detailed information. The following linker options are

new for ADS 1.1:

-callgraph

This option creates a static callgraph of functions in HTML format. The

callgraph gives stack usage, definition, and reference information for all

functions in the image.

-edit file

This option enables you to specify a steering file containing commands

to edit the symbol tables in the output binary.

-unmangled

This option instructs the linker to display unmangled C++ symbol names

in diagnostic messages and listings.
