/* 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. */
