/*This header file defines a table of extensions to the ARC processor
|
|
architecture. These extensions are read from the '.arcextmap' or
|
|
'.gnu.linkonce.arcextmap.<type>.<N>' sections in the ELF file which
|
|
is identified by the bfd parameter to the build_ARC_extmap function.
|
|
|
|
These extensions may include:
|
|
core registers
|
|
auxiliary registers
|
|
instructions
|
|
condition codes
|
|
|
|
Once the table has been constructed, accessor functions may be used
|
|
to retrieve information from it.
|
|
|
|
The build_ARC_extmap constructor function build_ARC_extmap may be
|
|
called as many times as required; it will re-initialize the table
|
|
each time. */
