-
-   TCG variables are the inputs and outputs of TCG ops, as described
-   in tcg/README. Target CPU front-end code uses these types to deal
-   with TCG variables as it emits TCG code via the tcg_gen_* functions.
-   They come in several flavours:
-    * TCGv_i32 : 32 bit integer type
-    * TCGv_i64 : 64 bit integer type
-    * TCGv_ptr : a host pointer type
-    * TCGv_vec : a host vector type; the exact size is not exposed
-                 to the CPU front-end code.
-    * TCGv : an integer type the same size as target_ulong
-             (an alias for either TCGv_i32 or TCGv_i64)
-   The compiler's type checking will complain if you mix them
-   up and pass the wrong sized TCGv to a function.
-
-   Users of tcg_gen_* don't need to know about any of the internal
-   details of these, and should treat them as opaque types.
-   You won't be able to look inside them in a debugger either.
-
-   Internal implementation details follow:
-
-   Note that there is no definition of the structs TCGv_i32_d etc anywhere.
-   This is deliberate, because the values we store in variables of type
-   TCGv_i32 are not really pointers-to-structures. They're just small
-   integers, but keeping them in pointer types like this means that the
-   compiler will complain if you accidentally pass a TCGv_i32 to a
-   function which takes a TCGv_i64, and so on. Only the internals of
-   TCG need to care about the actual contents of the types.  */

- * tcg_qemu_tb_exec:
- * @env: pointer to CPUArchState for the CPU
- * @tb_ptr: address of generated code for the TB to execute
- *
- * Start executing code from a given translation block.
- * Where translation blocks have been linked, execution
- * may proceed from the given TB into successive ones.
- * Control eventually returns only when some action is needed
- * from the top-level loop: either control must pass to a TB
- * which has not yet been directly linked, or an asynchronous
- * event such as an interrupt needs handling.
- *
- * Return: The return value is the value passed to the corresponding
- * tcg_gen_exit_tb() at translation time of the last TB attempted to execute.
- * The value is either zero or a 4-byte aligned pointer to that TB combined
- * with additional information in its two least significant bits. The
- * additional information is encoded as follows:
- *  0, 1: the link between this TB and the next is via the specified
- *        TB index (0 or 1). That is, we left the TB via (the equivalent
- *        of) "goto_tb <index>". The main loop uses this to determine
- *        how to link the TB just executed to the next.
- *  2:    we are using instruction counting code generation, and we
- *        did not start executing this TB because the instruction counter
- *        would hit zero midway through it. In this case the pointer
- *        returned is the TB we were about to execute, and the caller must
- *        arrange to execute the remaining count of instructions.
- *  3:    we stopped because the CPU's exit_request flag was set
- *        (usually meaning that there is an interrupt that needs to be
- *        handled). The pointer returned is the TB we were about to execute
- *        when we noticed the pending exit request.
- *
- * If the bottom two bits indicate an exit-via-index then the CPU
- * state is correctly synchronised and ready for execution of the next
- * TB (and in particular the guest PC is the address to execute next).
- * Otherwise, we gave up on execution of this TB before it started, and
- * the caller must fix up the CPU state by calling the CPU's
- * synchronize_from_tb() method with the TB pointer we return (falling
- * back to calling the CPU's set_pc method with tb->pb if no
- * synchronize_from_tb() method exists).
- *
- * Note that TCG targets may use a different definition of tcg_qemu_tb_exec
- * to this default (which just calls the prologue.code emitted by
- * tcg_target_qemu_prologue()).

+
+   TCG variables are the inputs and outputs of TCG ops, as described
+   in tcg/README. Target CPU front-end code uses these types to deal
+   with TCG variables as it emits TCG code via the tcg_gen_* functions.
+   They come in several flavours:
+    * TCGv_i32 : 32 bit integer type
+    * TCGv_i64 : 64 bit integer type
+    * TCGv_ptr : a host pointer type
+    * TCGv_vec : a host vector type; the exact size is not exposed
+                 to the CPU front-end code.
+    * TCGv : an integer type the same size as target_ulong
+             (an alias for either TCGv_i32 or TCGv_i64)
+   The compiler's type checking will complain if you mix them
+   up and pass the wrong sized TCGv to a function.
+
+   Users of tcg_gen_* don't need to know about any of the internal
+   details of these, and should treat them as opaque types.
+   You won't be able to look inside them in a debugger either.
+
+   Internal implementation details follow:
+
+   Note that there is no definition of the structs TCGv_i32_d etc anywhere.
+   This is deliberate, because the values we store in variables of type
+   TCGv_i32 are not really pointers-to-structures. They're just small
+   integers, but keeping them in pointer types like this means that the
+   compiler will complain if you accidentally pass a TCGv_i32 to a
+   function which takes a TCGv_i64, and so on. Only the internals of
+   TCG need to care about the actual contents of the types.  */

+ * which has not yet been directly linked, or an asynchronous
+ * event such as an interrupt needs handling.
+ *
+ * Return: The return value is the value passed to the corresponding
+ * tcg_gen_exit_tb() at translation time of the last TB attempted to execute.
+ * The value is either zero or a 4-byte aligned pointer to that TB combined
+ * with additional information in its two least significant bits. The
+ * additional information is encoded as follows:
+ *  0, 1: the link between this TB and the next is via the specified
+ *        TB index (0 or 1). That is, we left the TB via (the equivalent
+ *        of) "goto_tb <index>". The main loop uses this to determine
+ *        how to link the TB just executed to the next.
+ *  2:    we are using instruction counting code generation, and we
+ *        did not start executing this TB because the instruction counter
+ *        would hit zero midway through it. In this case the pointer
+ *        returned is the TB we were about to execute, and the caller must
+ *        arrange to execute the remaining count of instructions.
+ *  3:    we stopped because the CPU's exit_request flag was set
+ *        (usually meaning that there is an interrupt that needs to be
+ *        handled). The pointer returned is the TB we were about to execute
+ *        when we noticed the pending exit request.
+ *
+ * If the bottom two bits indicate an exit-via-index then the CPU
+ * state is correctly synchronised and ready for execution of the next
+ * TB (and in particular the guest PC is the address to execute next).
+ * Otherwise, we gave up on execution of this TB before it started, and
+ * the caller must fix up the CPU state by calling the CPU's
+ * synchronize_from_tb() method with the TB pointer we return (falling
+ * back to calling the CPU's set_pc method with tb->pb if no
+ * synchronize_from_tb() method exists).
+ *

+ * to this default (which just calls the prologue.code emitted by
