393 TCG variables are the inputs and outputs of TCG ops, as described
394 in tcg/README. Target CPU front-end code uses these types to deal
395 with TCG variables as it emits TCG code via the tcg_gen_* functions.
396 They come in several flavours:
397 * TCGv_i32 : 32 bit integer type
398 * TCGv_i64 : 64 bit integer type
399 * TCGv_ptr : a host pointer type
400 * TCGv : an integer type the same size as target_ulong
401 (an alias for either TCGv_i32 or TCGv_i64)
402 The compiler's type checking will complain if you mix them
403 up and pass the wrong sized TCGv to a function.
405 Users of tcg_gen_* don't need to know about any of the internal
406 details of these, and should treat them as opaque types.
407 You won't be able to look inside them in a debugger either.
409 Internal implementation details follow:
411 Note that there is no definition of the structs TCGv_i32_d etc anywhere.
412 This is deliberate, because the values we store in variables of type
413 TCGv_i32 are not really pointers-to-structures. They're just small
414 integers, but keeping them in pointer types like this means that the
415 compiler will complain if you accidentally pass a TCGv_i32 to a
416 function which takes a TCGv_i64, and so on. Only the internals of
417 TCG need to care about the actual contents of the types, and they always
418 box and unbox via the MAKE_TCGV_* and GET_TCGV_* functions.
419 Converting to and from intptr_t rather than int reduces the number
420 of sign-extension instructions that get implied on 64-bit hosts. */

1123 * Return: The return value is the value passed to the corresponding
1124 * tcg_gen_exit_tb() at translation time of the last TB attempted to execute.

1127 * additional information is encoded as follows:
1128 * 0, 1: the link between this TB and the next is via the specified
1129 * TB index (0 or 1). That is, we left the TB via (the equivalent
1130 * of) "goto_tb <index>". The main loop uses this to determine
1131 * how to link the TB just executed to the next.
1132 * 2: we are using instruction counting code generation, and we
1133 * did not start executing this TB because the instruction counter
1134 * would hit zero midway through it. In this case the pointer
1135 * returned is the TB we were about to execute, and the caller must
1136 * arrange to execute the remaining count of instructions.
1137 * 3: we stopped because the CPU's exit_request flag was set
1138 * (usually meaning that there is an interrupt that needs to be
1139 * handled). The pointer returned is the TB we were about to execute
1140 * when we noticed the pending exit request.
1142 * If the bottom two bits indicate an exit-via-index then the CPU
1143 * state is correctly synchronised and ready for execution of the next
1144 * TB (and in particular the guest PC is the address to execute next).
1145 * Otherwise, we gave up on execution of this TB before it started, and
1146 * the caller must fix up the CPU state by calling the CPU's
1147 * synchronize_from_tb() method with the TB pointer we return (falling
1148 * back to calling the CPU's set_pc method with tb->pb if no
1149 * synchronize_from_tb() method exists).
1151 * Note that TCG targets may use a different definition of tcg_qemu_tb_exec
1152 * to this default (which just calls the prologue.code emitted by
1153 * tcg_target_qemu_prologue()).
