2.3.2 Differences in default behavior

This section describes how the default behavior of ADS 1.1 differs from that of ADS

1.0. The major changes are:

• The CodeWarrior IDE, fromELF, and armsd are now license-managed in the

same way as other components of ADS.

• The linker now unmangles C++ symbol names when generating diagnostic

messages or listings. This is the default. You can use the

-mangled

option to

change the behavior.

• The byte order of an ARMulator target can now be set in the target configuration

dialog in AXD and ADW.

• The ARM compilers now require the stack to be 8-byte aligned.

• AXD now starts up with much more of its state reproduced from the last session.

• The compilers now perform auto-inlining by default for optimization level

-O2

• The compilers now perform range-splitting optimization at optimization level

-O1

(previously only done for

-O2

• The default filename for binary output from the compiler is now

__image.axf

That is,

armcc sourcename.c

, with no output name specified by the

-o

option, now

generates

__image.axf

, not

sourcename

• The ARMulator default behavior has changed. Branches to address zero are now

trapped only if you are running the FPE.
