+
+This target is intended for embedded Xtensa systems using the
+@samp{newlib} C library.  It uses ELF but does not support shared
+objects.  Designed-defined instructions specified via the
+Tensilica Instruction Extension (TIE) language are only supported
+through inline assembly.
+
+The Xtensa configuration information must be specified prior to
+building GCC@.  The @file{gcc/config/xtensa/xtensa-config.h} header
+file contains the configuration information.  If you created your
+own Xtensa configuration with the Xtensa Processor Generator, the
+downloaded files include a customized copy of this header file,
+which you can use to replace the default header file.

+
+This target is for Xtensa systems running GNU/Linux.  It supports ELF
+shared objects and the GNU C library (glibc).  It also generates
+position-independent code (PIC) regardless of whether the
+@option{-fpic} or @option{-fPIC} options are used.  In other
+respects, this target is the same as the 
+@uref{#xtensa-*-elf,,@samp{xtensa-*-elf}} target.
