*** Changes since GDB 9
+* There are new feature names for ARC targets: "org.gnu.gdb.arc.core"
+ and "org.gnu.gdb.arc.aux". The old names are still supported but
+ must be considered obsolete. They will be deprecated after some
+ grace period.
+
* Help and apropos commands will now show the documentation of a
command only once, even if that command has one or more aliases.
These commands now show the command name, then all of its aliases,

@subsection ARC Features
@cindex target descriptions, ARC Features
-ARC processors are highly configurable, so even core registers and their number
-are not completely predetermined. In addition flags and PC registers which are
-important to @value{GDBN} are not ``core'' registers in ARC. It is required
-that one of the core registers features is present.
-@samp{org.gnu.gdb.arc.aux-minimal} feature is mandatory.
-
-The @samp{org.gnu.gdb.arc.core.v2} feature is required for ARC EM and ARC HS
-targets with a normal register file. It should contain registers @samp{r0}
-through @samp{r25}, @samp{gp}, @samp{fp}, @samp{sp}, @samp{r30}, @samp{blink},
-@samp{lp_count} and @samp{pcl}. This feature may contain register @samp{ilink}
-and any of extension core registers @samp{r32} through @samp{r59/acch}.
-@samp{ilink} and extension core registers are not available to read/write, when
-debugging GNU/Linux applications, thus @samp{ilink} is made optional.
-
-The @samp{org.gnu.gdb.arc.core-reduced.v2} feature is required for ARC EM and
-ARC HS targets with a reduced register file. It should contain registers
-@samp{r0} through @samp{r3}, @samp{r10} through @samp{r15}, @samp{gp},
-@samp{fp}, @samp{sp}, @samp{r30}, @samp{blink}, @samp{lp_count} and @samp{pcl}.
-This feature may contain register @samp{ilink} and any of extension core
-registers @samp{r32} through @samp{r59/acch}.
-
-The @samp{org.gnu.gdb.arc.core.arcompact} feature is required for ARCompact
-targets with a normal register file. It should contain registers @samp{r0}
-through @samp{r25}, @samp{gp}, @samp{fp}, @samp{sp}, @samp{r30}, @samp{blink},
-@samp{lp_count} and @samp{pcl}. This feature may contain registers
-@samp{ilink1}, @samp{ilink2} and any of extension core registers @samp{r32}
-through @samp{r59/acch}. @samp{ilink1} and @samp{ilink2} and extension core
-registers are not available when debugging GNU/Linux applications. The only
-difference with @samp{org.gnu.gdb.arc.core.v2} feature is in the names of
-@samp{ilink1} and @samp{ilink2} registers and that @samp{r30} is mandatory in
-ARC v2, but @samp{ilink2} is optional on ARCompact.
-
-The @samp{org.gnu.gdb.arc.aux-minimal} feature is required for all ARC
-targets. It should contain registers @samp{pc} and @samp{status32}.
+ARC processors are so configurable that even core registers and their numbers
+are not predetermined completely. Moreover, @emph{flags} and @emph{PC}
+registers, which are important to @value{GDBN}, are not ``core'' registers in
+ARC. Therefore, there are two features that their presence is mandatory:
+@samp{org.gnu.gdb.arc.core} and @samp{org.gnu.gdb.arc.aux}.
+
+The @samp{org.gnu.gdb.arc.core} feature is required for all targets. It must
+contain registers:
+
+@itemize @minus
+@item
+@samp{r0} through @samp{r25} for normal register file targets.
+@item
+@samp{r0} through @samp{r3}, and @samp{r10} through @samp{r15} for reduced
+register file targets.
+@item
+@samp{gp}, @samp{fp}, @samp{sp}, @samp{r30}@footnote{Not necessary for ARCv1.},
+@samp{blink}, @samp{lp_count}, @samp{pcl}.
+@end itemize
+
+In case of an ARCompact target (ARCv1 ISA), the @samp{org.gnu.gdb.arc.core}
+feature may contain registers @samp{ilink1} and @samp{ilink2}. While in case
+of ARC EM and ARC HS targets (ARCv2 ISA), register @samp{ilink} may be present.
+The difference between ARCv1 and ARCv2 is the naming of registers @emph{29th}
+and @emph{30th}. They are called @samp{ilink1} and @samp{ilink2} for ARCv1 and
+are optional. For ARCv2, they are called @samp{ilink} and @samp{r30} and only
+@samp{ilink} is optional. The optionality of @samp{ilink*} registers is
+because of their inaccessibility during user space debugging sessions.
+
+Extension core registers @samp{r32} through @samp{r59} are optional and their
+existence depends on the configuration. When debugging GNU/Linux applications,
+i.e.@: user space debugging, these core registers are not available.
+
+The @samp{org.gnu.gdb.arc.aux} feature is required for all ARC targets. It
+should at least contain @samp{pc} and @samp{status32} registers.
