These commands are helpful in getting your project properly configured and initialized
because all C start-up modules have to do many of the same tasks.
The standard start-up commands define a number of linker symbols that are used in the
standard start-up module for initializing the C run-time environment. You do not have to
refer to those symbols in your own start-up module, but many users will find it useful to
do so, especially since user-customized start-up modules are often derived from modifying
the standard start-up module. There are also a few linker commands (such as
CHANGE ,
COPY , ORDER , and GROUP ) that are used to configure your memory map. See the Linker
Commands section on page 347 for a description of these commands.
Use Standard Start-Up Linker Commands
If you select this checkbox, the same linker commands that support the standard start-up
module are inserted into your linker command file, even though you have chosen to
include your own, nonstandard start-up module in the project. This option is usually help-
ful in getting your project properly configured and initialized because all C start-up mod-
ules have to do most of the same tasks. Formerly, these linker commands had to be
inserted manually when you were not using the standard start-up.

This option is only available when the Included in Project button has been selected. The
default for newly created projects is that this checkbox, if available, is selected.
Use Default Libraries
These controls determine whether the available default libraries that are shipped with
Zilog Developer Studio II are to be linked with your application. For Z8 Encore!, there are
two available libraries, the C run-time library and the Zilog Standard Library (ZSL). The
subset of the run-time library dedicated to floating-point operations also has a separate
control to allow for special handling, as explained in the
Floating Point Library section on
page 102.
None of the libraries mentioned here are available for Assembly Only projects.
C Runtime Library
The C run-time library included with ZDS II provides selected functions and macros from
the Standard C Library. Zilog’s version of the C run-time library supports a subset of the
