-subsubsection {* Invoking the code generator *}
-
-text {* The code generator is invoked via the @{command code_module}
-  and @{command code_library} commands, which correspond to
-  \emph{incremental} and \emph{modular} code generation, respectively.
-
-  \begin{description}
-
-  \item [Modular] For each theory, an ML structure is generated,
-  containing the code generated from the constants defined in this
-  theory.
-
-  \item [Incremental] All the generated code is emitted into the same
-  structure.  This structure may import code from previously generated
-  structures, which can be specified via @{keyword "imports"}.
-  Moreover, the generated structure may also be referred to in later
-  invocations of the code generator.
-
-  \end{description}
-
-  After the @{command code_module} and @{command code_library}
-  keywords, the user may specify an optional list of ``modes'' in
-  parentheses. These can be used to instruct the code generator to
-  emit additional code for special purposes, e.g.\ functions for
-  converting elements of generated datatypes to Isabelle terms, or
-  test data generators. The list of modes is followed by a module
-  name.  The module name is optional for modular code generation, but
-  must be specified for incremental code generation.
-
-  The code can either be written to a file, in which case a file name
-  has to be specified after the @{keyword "file"} keyword, or be loaded
-  directly into Isabelle's ML environment. In the latter case, the
-  @{command ML} theory command can be used to inspect the results
-  interactively, for example.
-
-  The terms from which to generate code can be specified after the
-  @{keyword "contains"} keyword, either as a list of bindings, or just
-  as a list of terms. In the latter case, the code generator just
-  produces code for all constants and types occuring in the term, but
-  does not bind the compiled terms to ML identifiers.
-
-  Here is an example:
-*}
-
-code_module Test
-contains test = "foldl op + (0 :: int) [1, 2, 3, 4, 5]"
-
-text {* \noindent This binds the result of compiling the given term to
-  the ML identifier @{ML Test.test}.  *}
-
-ML {* @{assert} (Test.test = 15) *}
-
-
-subsubsection {* Configuring the code generator *}
-
-text {* When generating code for a complex term, the code generator
-  recursively calls itself for all subterms.  When it arrives at a
-  constant, the default strategy of the code generator is to look up
-  its definition and try to generate code for it.  Constants which
-  have no definitions that are immediately executable, may be
-  associated with a piece of ML code manually using the @{command_ref
-  consts_code} command.  It takes a list whose elements consist of a
-  constant (given in usual term syntax -- an explicit type constraint
-  accounts for overloading), and a mixfix template describing the ML
-  code. The latter is very much the same as the mixfix templates used
-  when declaring new constants.  The most notable difference is that
-  terms may be included in the ML template using antiquotation
-  brackets @{verbatim "{"}@{verbatim "*"}~@{text "..."}~@{verbatim
-  "*"}@{verbatim "}"}.
-
-  A similar mechanism is available for types: @{command_ref
-  types_code} associates type constructors with specific ML code.
-
-  For example, the following declarations copied from @{file
-  "~~/src/HOL/Product_Type.thy"} describe how the product type of
-  Isabelle/HOL should be compiled to ML.  *}
-
-typedecl ('a, 'b) prod
-consts Pair :: "'a \<Rightarrow> 'b \<Rightarrow> ('a, 'b) prod"
-
-types_code prod  ("(_ */ _)")
-consts_code Pair  ("(_,/ _)")
-
-text {* Sometimes, the code associated with a constant or type may
-  need to refer to auxiliary functions, which have to be emitted when
-  the constant is used. Code for such auxiliary functions can be
-  declared using @{keyword "attach"}. For example, the @{const wfrec}
-  function can be implemented as follows:
-*}
-
-consts_code wfrec  ("\<module>wfrec?")  (* FIXME !? *)
-attach {* fun wfrec f x = f (wfrec f) x *}
-
-text {* If the code containing a call to @{const wfrec} resides in an
-  ML structure different from the one containing the function
-  definition attached to @{const wfrec}, the name of the ML structure
-  (followed by a ``@{text "."}'')  is inserted in place of ``@{text
-  "\<module>"}'' in the above template.  The ``@{text "?"}''  means that
-  the code generator should ignore the first argument of @{const
-  wfrec}, i.e.\ the termination relation, which is usually not
-  executable.
-
-  \medskip Another possibility of configuring the code generator is to
-  register theorems to be used for code generation. Theorems can be
-  registered via the @{attribute code} attribute. It takes an optional
-  name as an argument, which indicates the format of the
-  theorem. Currently supported formats are equations (this is the
-  default when no name is specified) and horn clauses (this is
-  indicated by the name \texttt{ind}). The left-hand sides of
-  equations may only contain constructors and distinct variables,
-  whereas horn clauses must have the same format as introduction rules
-  of inductive definitions.
-
-  The following example specifies three equations from which to
-  generate code for @{term "op <"} on natural numbers (see also
-  @{"file" "~~/src/HOL/Nat.thy"}).  *}
-
-lemma [code]: "(Suc m < Suc n) = (m < n)"
-  and [code]: "((n::nat) < 0) = False"
-  and [code]: "(0 < Suc n) = True" by simp_all
-
-
-subsubsection {* Specific HOL code generators *}
-
-text {* The basic code generator framework offered by Isabelle/Pure
-  has already been extended with additional code generators for
-  specific HOL constructs. These include datatypes, recursive
-  functions and inductive relations. The code generator for inductive
-  relations can handle expressions of the form @{text "(t\<^sub>1, \<dots>, t\<^sub>n) \<in>
-  r"}, where @{text "r"} is an inductively defined relation. If at
-  least one of the @{text "t\<^sub>i"} is a dummy pattern ``@{text "_"}'',
-  the above expression evaluates to a sequence of possible answers. If
-  all of the @{text "t\<^sub>i"} are proper terms, the expression evaluates
-  to a boolean value.
-
-  The following example demonstrates this for beta-reduction on lambda
-  terms (see also @{"file" "~~/src/HOL/Proofs/Lambda/Lambda.thy"}).
-*}

-\begin{isamarkuptext}%
-The code generator is invoked via the \hyperlink{command.code-module}{\mbox{\isa{\isacommand{code{\isaliteral{5F}{\isacharunderscore}}module}}}}
-  and \hyperlink{command.code-library}{\mbox{\isa{\isacommand{code{\isaliteral{5F}{\isacharunderscore}}library}}}} commands, which correspond to
-  \emph{incremental} and \emph{modular} code generation, respectively.
-
-  \begin{description}
-
-  \item [Modular] For each theory, an ML structure is generated,
-  containing the code generated from the constants defined in this
-  theory.
-
-  \item [Incremental] All the generated code is emitted into the same
-  structure.  This structure may import code from previously generated
-  structures, which can be specified via \hyperlink{keyword.imports}{\mbox{\isa{\isakeyword{imports}}}}.
-  Moreover, the generated structure may also be referred to in later
-  invocations of the code generator.
-
-  \end{description}
-
-  After the \hyperlink{command.code-module}{\mbox{\isa{\isacommand{code{\isaliteral{5F}{\isacharunderscore}}module}}}} and \hyperlink{command.code-library}{\mbox{\isa{\isacommand{code{\isaliteral{5F}{\isacharunderscore}}library}}}}
-  keywords, the user may specify an optional list of ``modes'' in
-  parentheses. These can be used to instruct the code generator to
-  emit additional code for special purposes, e.g.\ functions for
-  converting elements of generated datatypes to Isabelle terms, or
-  test data generators. The list of modes is followed by a module
-  name.  The module name is optional for modular code generation, but
-  must be specified for incremental code generation.
-
-  The code can either be written to a file, in which case a file name
-  has to be specified after the \hyperlink{keyword.file}{\mbox{\isa{\isakeyword{file}}}} keyword, or be loaded
-  directly into Isabelle's ML environment. In the latter case, the
-  \hyperlink{command.ML}{\mbox{\isa{\isacommand{ML}}}} theory command can be used to inspect the results
-  interactively, for example.
-
-  The terms from which to generate code can be specified after the
-  \hyperlink{keyword.contains}{\mbox{\isa{\isakeyword{contains}}}} keyword, either as a list of bindings, or just
-  as a list of terms. In the latter case, the code generator just
-  produces code for all constants and types occuring in the term, but
-  does not bind the compiled terms to ML identifiers.

-\isamarkupsubsubsection{Configuring the code generator%
-}
-\isamarkuptrue%
-%
-\begin{isamarkuptext}%
-When generating code for a complex term, the code generator
-  recursively calls itself for all subterms.  When it arrives at a
-  constant, the default strategy of the code generator is to look up
-  its definition and try to generate code for it.  Constants which
-  have no definitions that are immediately executable, may be
-  associated with a piece of ML code manually using the \indexref{}{command}{consts\_code}\hyperlink{command.consts-code}{\mbox{\isa{\isacommand{consts{\isaliteral{5F}{\isacharunderscore}}code}}}} command.  It takes a list whose elements consist of a
-  constant (given in usual term syntax -- an explicit type constraint
-  accounts for overloading), and a mixfix template describing the ML
-  code. The latter is very much the same as the mixfix templates used
-  when declaring new constants.  The most notable difference is that
-  terms may be included in the ML template using antiquotation
-  brackets \verb|{|\verb|*|~\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{2E}{\isachardot}}{\isaliteral{2E}{\isachardot}}{\isaliteral{2E}{\isachardot}}{\isaliteral{22}{\isachardoublequote}}}~\verb|*|\verb|}|.
-
-  A similar mechanism is available for types: \indexref{}{command}{types\_code}\hyperlink{command.types-code}{\mbox{\isa{\isacommand{types{\isaliteral{5F}{\isacharunderscore}}code}}}} associates type constructors with specific ML code.
-
-  For example, the following declarations copied from \verb|~~/src/HOL/Product_Type.thy| describe how the product type of
-  Isabelle/HOL should be compiled to ML.%

-\begin{isamarkuptext}%
-If the code containing a call to \isa{wfrec} resides in an
-  ML structure different from the one containing the function
-  definition attached to \isa{wfrec}, the name of the ML structure
-  (followed by a ``\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{2E}{\isachardot}}{\isaliteral{22}{\isachardoublequote}}}'')  is inserted in place of ``\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{5C3C6D6F64756C653E}{\isasymmodule}}{\isaliteral{22}{\isachardoublequote}}}'' in the above template.  The ``\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{3F}{\isacharquery}}{\isaliteral{22}{\isachardoublequote}}}''  means that
-  the code generator should ignore the first argument of \isa{wfrec}, i.e.\ the termination relation, which is usually not
-  executable.
-
-  \medskip Another possibility of configuring the code generator is to
-  register theorems to be used for code generation. Theorems can be
-  registered via the \hyperlink{attribute.code}{\mbox{\isa{code}}} attribute. It takes an optional
-  name as an argument, which indicates the format of the
-  theorem. Currently supported formats are equations (this is the
-  default when no name is specified) and horn clauses (this is
-  indicated by the name \texttt{ind}). The left-hand sides of
-  equations may only contain constructors and distinct variables,
-  whereas horn clauses must have the same format as introduction rules
-  of inductive definitions.
-
-  The following example specifies three equations from which to
-  generate code for \isa{{\isaliteral{22}{\isachardoublequote}}op\ {\isaliteral{3C}{\isacharless}}{\isaliteral{22}{\isachardoublequote}}} on natural numbers (see also

-\begin{isamarkuptext}%
-The basic code generator framework offered by Isabelle/Pure
-  has already been extended with additional code generators for
-  specific HOL constructs. These include datatypes, recursive

-  relations can handle expressions of the form \isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{28}{\isacharparenleft}}t\isaliteral{5C3C5E7375623E}{}\isactrlsub {\isadigit{1}}{\isaliteral{2C}{\isacharcomma}}\ {\isaliteral{5C3C646F74733E}{\isasymdots}}{\isaliteral{2C}{\isacharcomma}}\ t\isaliteral{5C3C5E7375623E}{}\isactrlsub n{\isaliteral{29}{\isacharparenright}}\ {\isaliteral{5C3C696E3E}{\isasymin}}\ r{\isaliteral{22}{\isachardoublequote}}}, where \isa{{\isaliteral{22}{\isachardoublequote}}r{\isaliteral{22}{\isachardoublequote}}} is an inductively defined relation. If at
-  least one of the \isa{{\isaliteral{22}{\isachardoublequote}}t\isaliteral{5C3C5E7375623E}{}\isactrlsub i{\isaliteral{22}{\isachardoublequote}}} is a dummy pattern ``\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{5F}{\isacharunderscore}}{\isaliteral{22}{\isachardoublequote}}}'',
