mapping obj files contents to sections [message #524644]

In our current linker command files (TI c6000 linker), we have created
sections from obj files in a lib as groups and mapped them into memory
segments. See below for an example:

GROUP (RACFD_PRINT_LOG_PRINT)
{
.racfd_print_log_print
{
-lracfd.lib <RACFD_*_logPrint.obj> (.text)
-lracfd.lib <RACFD_*_logPrint.obj> (.const)
-lracfd.lib <RACFD_*_logPrint.obj> (.switch)
-lracfd.lib <RACFD_*_logPrint.obj> (.data)
-lracfd.lib <RACFD_*_logPrint.obj> (.bss)
-lracfd.lib <RACFD_*_logPrint.obj> (.data)
-lracfd.lib <RACFD_*_logPrint.obj> (.far)

-lracfd.lib <RACFD_*_print.obj> (.text)
-lracfd.lib <RACFD_*_print.obj> (.const)
-lracfd.lib <RACFD_*_print.obj> (.switch)
-lracfd.lib <RACFD_*_print.obj> (.data)
-lracfd.lib <RACFD_*_print.obj> (.bss)
-lracfd.lib <RACFD_*_print.obj> (.data)
-lracfd.lib <RACFD_*_print.obj> (.far)

-lracfd.lib <RACFD_*_literal*.obj> (.text)
-lracfd.lib <RACFD_*_literal*.obj> (.const)
-lracfd.lib <RACFD_*_literal*.obj> (.switch)
-lracfd.lib <RACFD_*_literal*.obj> (.data)
-lracfd.lib <RACFD_*_literal*.obj> (.bss)
-lracfd.lib <RACFD_*_literal*.obj> (.data)
-lracfd.lib <RACFD_*_literal*.obj> (.far)

-lracfd.lib <RACFD_facadeClassApi*.obj> (.text)
-lracfd.lib <RACFD_facadeClassApi*.obj> (.const)
-lracfd.lib <RACFD_facadeClassApi*.obj> (.switch)
-lracfd.lib <RACFD_facadeClassApi*.obj> (.data)
-lracfd.lib <RACFD_facadeClassApi*.obj> (.bss)
-lracfd.lib <RACFD_facadeClassApi*.obj> (.data)
-lracfd.lib <RACFD_facadeClassApi*.obj> (.far)
}
} > EXT

How can we achieve this with XDCtools?

One possibility is to leverage the getSects() method; see
http://rtsc.eclipse.org/cdoc-tip/index.html#xdc/IPackage.htm l#get.Sects

This method allows a package to contribute content to the generated
linker command file used to link an executable. The implementation of
this method, like that of getLibs(), is in the package's package.xs file.
