DESCRIPTION
|
|
This module is responsible for the generation of the absolute symbols whose
|
|
value represents the member offsets for various ARCv2 nanokernel
|
|
structures.
|
|
|
|
All of the absolute symbols defined by this module will be present in the
|
|
final microkernel or nanokernel ELF image (due to the linker's reference to
|
|
the _OffsetAbsSyms symbol).
|
|
|
|
INTERNAL
|
|
It is NOT necessary to define the offset for every member of a structure.
|
|
Typically, only those members that are accessed by assembly language routines
|
|
are defined; however, it doesn't hurt to define all fields for the sake of
|
|
completeness.
