/*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. */
