Hello,
What I see here is two questions: one asking to set the base of .text, the other is asking how to create new sections. Creating new sections is possible (please see next paragraph) but setting a specific location for .text is not... there really isn't any need for it.
The closest thing provided is a
pragma extension that can be used for creating sections and section alignment; the actual placement of the sections cannot be set to specific linear addresses as with LD. Also note that it is limited to C linkage of functions.
This directive can also be used to define and set section properties that the OS can use when allocating pages for the section.
