/*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. */
