+;   2) At most 2 iops to the branch unit
+; Note that insn position in a dispatch group of 6 insns does not infer which
+; execution slice the insn is routed to.  The units are used to infer the
+; conflicts that exist (i.e. an 'even' requirement will preclude dispatch
+; with 2 insns with 'superslice' requirement).
+
+; The xa0/xa1 units really represent the 3rd dispatch port for a superslice but

+; still be scheduled two to a superslice while reserving the 3rd slot.  The

+
+     The UltraSPARC-III features a documented prefetch queue with a

+     dropped.
+
+     Niagara processors are different.  In these processors prefetches

+     become occupied.  That occupation could be a mix of regular loads
+     and prefetches though.  And that buffer is shared by all threads.
+     Once the threshold is reached, if the core is running a single
+     thread the prefetch will retry.  If more than one thread is
+     running, the prefetch will be dropped.
+
+     All this makes it very difficult to determine how many

+@noindent
+GNU Fortran implements STRUCTURES like derived types with the following
+rules and exceptions:
+
+@itemize @bullet
+@item Structures act like derived types with the @code{SEQUENCE} attribute.
+Otherwise they may contain no specifiers.
 
-@c @node UNION and MAP
-@c @subsection @code{UNION} and @code{MAP}
-@c @cindex @code{UNION}
-@c @cindex @code{MAP}
-@c
-@c For help writing this one, see
-@c http://www.eng.umd.edu/~nsw/ench250/fortran1.htm#UNION and
-@c http://www.tacc.utexas.edu/services/userguides/pgi/pgiws_ug/pgi32u06.htm
+@item Structures may share names with other symbols. For example, the following
+is invalid for derived types, but valid for structures:
 
+@smallexample
+structure /header/
+  ! ...
+end structure
+record /header/ header
+@end smallexample
+
+@item Structure types may be declared nested within another parent structure.
+The syntax is:
+@smallexample
+structure /type-name/
+    ...
+    structure [/<type-name>/] <field-list>
+...
+@end smallexample
+
+The type name may be ommitted, in which case the structure type itself is
+anonymous, and other structures of the same type cannot be instantiated. The
+following shows some examples:
+
+@example
+structure /appointment/
+  ! nested structure definition: app_time is an array of two 'time'
+  structure /time/ app_time (2) 
+    integer(1) hour, minute
+  end structure
+  character(10) memo
+end structure
+
+! The 'time' structure is still usable
+record /time/ now
+now = time(5, 30)
+
+...
+
+structure /appointment/
+  ! anonymous nested structure definition
+  structure start, end
+    integer(1) hour, minute
+  end structure
+  character(10) memo
+end structure
+@end example
+
+@item Structures may contain @code{UNION} blocks. For more detail see the
+section on @ref{UNION and MAP}.
+
+@item Structures support old-style initialization of components, like
+those described in @ref{Old-style variable initialization}. For array
+initializers, an initializer may contain a repeat specification of the form
+@code{<literal-integer> * <constant-initializer>}. The value of the integer
+indicates the number of times to repeat the constant initializer when expanding
+the initializer list.
+@end itemize
+
+@node UNION and MAP
+@subsection @code{UNION} and @code{MAP}
+@cindex @code{UNION}
+@cindex @code{MAP}
+
+Unions are an old vendor extension which were commonly used with the
+non-standard @ref{STRUCTURE and RECORD} extensions. Use of @code{UNION} and
+@code{MAP} is automatically enabled with @option{-fdec-structure}.
+
+A @code{UNION} declaration occurs within a structure; within the definition of
+each union is a number of @code{MAP} blocks. Each @code{MAP} shares storage
+with its sibling maps (in the same union), and the size of the union is the
+size of the largest map within it, just as with unions in C. The major
+difference is that component references do not indicate which union or map the
+component is in (the compiler gets to figure that out).
+
+Here is a small example:
+@smallexample
+structure /myunion/
+union
+  map
+    character(2) w0, w1, w2
+  end map
+  map
+    character(6) long
+  end map
+end union
+end structure
+
+record /myunion/ rec
+! After this assignment...
+rec.long = 'hello!'
+
+! The following is true:
+! rec.w0 === 'he'
+! rec.w1 === 'll'
+! rec.w2 === 'o!'
+@end smallexample
+
+The two maps share memory, and the size of the union is ultimately six bytes:
+
+@example
+0    1    2    3    4   5   6     Byte offset
+-------------------------------
+|    |    |    |    |    |    |
+-------------------------------
+
+^    W0   ^    W1   ^    W2   ^
+ \-------/ \-------/ \-------/
+
+^             LONG            ^
+ \---------------------------/
+@end example
+
+Following is an example mirroring the layout of an Intel x86_64 register:
+
+@example
+structure /reg/
+  union ! U0                ! rax
+    map
+      character(16) rx
+    end map
+    map
+      character(8) rh         ! rah
+      union ! U1
+        map
+          character(8) rl     ! ral
+        end map
+        map
+          character(8) ex     ! eax
+        end map
+        map
+          character(4) eh     ! eah
+          union ! U2
+            map
+              character(4) el ! eal
+            end map
+            map
+              character(4) x  ! ax
+            end map
+            map
+              character(2) h  ! ah
+              character(2) l  ! al
+            end map
+          end union
+        end map
+      end union
+    end map
+  end union
+end structure
+record /reg/ a
+
+! After this assignment...
+a.rx     =     'AAAAAAAA.BBB.C.D'
+
+! The following is true:
+a.rx === 'AAAAAAAA.BBB.C.D'
+a.rh === 'AAAAAAAA'
+a.rl ===         '.BBB.C.D'
+a.ex ===         '.BBB.C.D'
+a.eh ===         '.BBB'
+a.el ===             '.C.D'

 /******************** Generic matching subroutines ************************/
 
+/* Matches a member separator. With standard FORTRAN this is '%', but with
+   DEC structures we must carefully match dot ('.').
+   Because operators are spelled ".op.", a dotted string such as "x.y.z..."
+   can be either a component reference chain or a combination of binary
+   operations.
+   There is no real way to win because the string may be grammatically
+   ambiguous. The following rules help avoid ambiguities - they match
+   some behavior of other (older) compilers. If the rules here are changed
+   the test cases should be updated. If the user has problems with these rules
+   they probably deserve the consequences. Consider "x.y.z":
+     (1) If any user defined operator ".y." exists, this is always y(x,z)
+         (even if ".y." is the wrong type and/or x has a member y).
+     (2) Otherwise if x has a member y, and y is itself a derived type,
+         this is (x->y)->z, even if an intrinsic operator exists which 
+         can handle (x,z). 
+     (3) If x has no member y or (x->y) is not a derived type but ".y." 
+         is an intrinsic operator (such as ".eq."), this is y(x,z).
+     (4) Lastly if there is no operator ".y." and x has no member "y", it is an
+         error.  
+   It is worth noting that the logic here does not support mixed use of member
+   accessors within a single string. That is, even if x has component y and y
+   has component z, the following are all syntax errors:
+         "x%y.z"  "x.y%z" "(x.y).z"  "(x%y)%z"
