* The XFLAT program image is divided into two segments:
|
|
*
|
|
* (1) ISpace (Instruction Space). This is the segment that contains
|
|
* code (.text). Everything in the segment should be fetch-able
|
|
* machine PC instructions (jump, branch, call, etc.).
|
|
* (2) DSpace (Data Space). This is the segment that contains both
|
|
* read-write data (.data, .bss) as well as read-only data (.rodata).
|
|
* Everything in this segment should be access-able with machine
|
|
* PIC load and store instructions.
|
|
*
|
|
* Older versions of GCC (at least up to GCC 4.3.3), use GOT-relative
|
|
* addressing to access RO data. In that case, read-only data (.rodata) must
|
|
* reside in D-Space and this linker script should be used.
|
|
*
|
|
* Newer versions of GCC (at least as of GCC 4.6.3), use PC-relative
|
|
* addressing to access RO data. In that case, read-only data (.rodata) must
|
|
* reside in I-Space and this linker script should NOT be used with those
|
|
* newer tools.
