18 * ======== Program ========
19 * The Program object for the configuration object model.
20 *
21 * This module defines the "root" of the configuration object model; all
22 * "top-level" configuration settings for the executable are provided by
23 * this object. Program configuration scripts reference this module via the
24 * global variable `Program`; i.e., `Program` is implicitly initialized as
25 * follows:
26 * @p(code)
27 * var Program = xdc.useModule('xdc.cfg.Program');
28 * @p
29 *
30 * After a configuration script completes successfully, the following files
31 * are generated:
32 * @p(nlist)
33 * - package/cfg/<exe_name>.c
34 * - package/cfg/<exe_name>.xdl
35 * @p
36 * where `<exe_name>` is the name of the executable with the final '.'
37 * character replaced with an '_'.
38 *
39 * The generated C file contains code and data from each module used by the
40 * program and must be compiled and linked with the other sources to
41 * produce the final executable. The generated linker command file must also
42 * be added during this final link step.
43 *
44 * The linker command file is produced by expanding a template
45 * provided by the platform specifed during configuration and contains
46 * hardware and compiler specific directives required by the target modules
47 * that are part of the program's configuration. This template expands
48 * other templates specified by each imported package's
49 * `{@link xdc.IPackage#getSects getSects}` method, for example. This allows
50 * each package participating in the configuration executable to
51 * automatically contribute a portion of the executable's linker command
52 * file.
53 *
54 * You can modify or augment the contents of this file via
55 * `{@link xdc.cfg.Program#sectionsExclude sectionsExclude}` and
56 * `{@link xdc.cfg.Program#sectionsTemplate sectionsTemplate}`. It is even
57 * possible to completely replace the template used to generate this file via
58 * `{@link xdc.cfg.Program#linkTemplate linkTemplate}`. These configuration
59 * options provide the user complete control of the linker command file

419 * @p

631 * in a generated header that is indirectly included by the header
632 * `xdc/cfg/global.h`.
633 *
634 * Configuration scripts define symbols by adding new properties to
635 * `global`.
636 * @p(code)
637 * Program.global.myInstance = Mod.create();
638 * Program.global.myString = "hello world";
639 * @p
640 *
641 * Programs can reference the symbols defined in `global` by including
642 * the C/C++ header `xdc/cfg/global.h` as follows:
643 * @p(code)
644 * #include <pkg/Mod.h>
645 * #include <xdc/cfg/global.h>
646 * :
647 * Mod_fxn(myInstance, ...);

649 * @p
650 *
651 * To compile sources that include `xdc/cfg/global.h`, one symbol must be
652 * defined before including this header:
653 * @p(dlist)
654 * - `xdc_cfg__header__`
655 * the package qualified name of the executable-specific C/C++
656 * header generated by the program configuration tool; e.g.,
657 * `local/examples/package/cfg/mycfg_x62.h`.
658 * @p
659 * For example, to compile sources that reference the values declared in
660 * `{@link #global}` for a TI C6x target with a generated
661 * configuration header named `package/cfg/mycfg_x62.h` in a package
662 * named `local.examples` the following command line is sufficient:
663 * @p(code)
664 * cl6x -Dxdc_cfg__header__=local/examples/package/cfg/mycfg_x62.h ...
665 * @p
666 *
667 * The `xdc_cfg__header__` symbol is automatically defined when you use
668 * the the XDC Build Engine (`{@link xdc.bld}`) to create executables; see
669 * `{@link xdc.bld.Executable#addObjects}`

692 * The line above causes the symbol "ONE" to be defined in the linker
693 * command file to be equal to 1. Note this in contrast to defining a
694 * variable whose value is 1; symbols do not occupy space, they are just
695 * symbolic constants defined in the symbol table of the executable.
696 *
697 * This is currently used by xdc.runtime.Startup to define symbols
698 * optionally referenced by boot files that support early startup
699 * "reset" functions.
