-
- 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. */

- *
- * 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
