Change the temps_in_use check to use assert not fprintf.
Move the assert for double-free before the check for count,
since that is the more immediate problem.

In preparation for returning the number of insns generated
via the same pointer. Adjust only the prototypes so far.

Write back the number of insns that we attempt to translate,
so that if we longjmp out we have a more accurate limit for
the next attempt. This results in fewer restarts when some
limit is consumed by few instructions.

Just because the label reference count is more than 1 does
not mean we cannot remove a branch-to-next. By doing this
first, the label reference count may drop to 0, and then
the label itself gets removed as before.

Use TEMP_TB as that is more explicit about the default

to be contrasting, we have more lifetimes than that now.
Do not yet rename tcg_temp_local_new_*, just the enum.

All of these uses have quite local scope.
Avoid tcg_const_*, because we haven't added a corresponding
interface for TEMP_EBB. Use explicit tcg_gen_movi_* instead.

Here we are creating a temp whose value needs to be replaced,
but always storing NULL into CPUState.plugin_mem_cbs.
Use tcg_constant_ptr(0) explicitly.

Reusing TEMP_TB interferes with detecting whether the

Guest front-ends now get temps that span the lifetime of
the translation block by default, which avoids accidentally
using the temp across branches and invalidating the data.

uses of new_tmp_a64_local(), so remove that as well.

Definitions
===========
-TCG receives RISC-like *TCG ops* and performs some optimizations on them,
-including liveness analysis and trivial constant expression
-evaluation. TCG ops are then implemented in the host CPU back end,
-also known as the TCG target.

-The TCG *target* is the architecture for which we generate the
-code. It is of course not the same as the "target" of QEMU which is
-the emulated architecture. As TCG started as a generic C backend used
-for cross compiling, it is assumed that the TCG target is different

-CPU register), a fixed host register (e.g. the QEMU CPU state pointer)
-or a memory location which is stored in a register outside QEMU TBs
-(not implemented yet).

-Introduction
-------------
+A TCG *basic block* is a single entry, multiple exit region which
+corresponds to a list of instructions terminated by a label, or
+any branch instruction.
-TCG instructions operate on variables which are temporaries, local
-temporaries or globals. TCG instructions and variables are strongly
-typed. Two types are supported: 32 bit integers and 64 bit
-integers. Pointers are defined as an alias to 32 bit or 64 bit
-integers depending on the TCG target word size.
+A TCG *extended basic block* is a single entry, multiple exit region
+which corresponds to a list of instructions terminated by a label or
+an unconditional branch. Specifically, an extended basic block is
+a sequence of basic blocks connected by the fall-through paths of
+zero or more conditional branch instructions.
-Each instruction has a fixed number of output variable operands, input
-variable operands and always constant operands.
+Operations
+==========
-The notable exception is the call instruction which has a variable
-number of outputs and inputs.
+TCG instructions or *ops* operate on TCG *variables*, both of which
+are strongly typed. Each instruction has a fixed number of output
+variable operands, input variable operands and constant operands.
+Vector instructions have a field specifying the element size within
+the vector. The notable exception is the call instruction which has
+a variable number of outputs and inputs.
In the textual form, output operands usually come first, followed by
input operands, followed by constant operands. The output type is

+Variables
+=========
-Assumptions
------------
+* ``TEMP_FIXED``
-Basic blocks
-^^^^^^^^^^^^
+ There is one TCG *fixed global* variable, ``cpu_env``, which is
+ live in all translation blocks, and holds a pointer to ``CPUArchState``.
+ This variable is held in a host cpu register at all times in all
+ translation blocks.
-* Basic blocks end after branches (e.g. brcond_i32 instruction),
- goto_tb and exit_tb instructions.
+* ``TEMP_GLOBAL``
-* Basic blocks start after the end of a previous basic block, or at a
- set_label instruction.
+ A TCG *global* is a variable which is live in all translation blocks,
+ and corresponds to memory location that is within ``CPUArchState``.
+ These may be specified as an offset from ``cpu_env``, in which case
+ they are called *direct globals*, or may be specified as an offset
+ from a direct global, in which case they are called *indirect globals*.
+ Even indirect globals should still reference memory within
+ ``CPUArchState``. All TCG globals are defined during
+ ``TCGCPUOps.initialize``, before any translation blocks are generated.
-After the end of a basic block, the content of temporaries is
-destroyed, but local temporaries and globals are preserved.
+* ``TEMP_CONST``
-Floating point types
-^^^^^^^^^^^^^^^^^^^^
+ A TCG *constant* is a variable which is live throughout the entire
+ translation block, and contains a constant value. These variables
+ are allocated on demand during translation and are hashed so that
+ there is exactly one variable holding a given value.
-* Floating point types are not supported yet
+* ``TEMP_TB``
-Pointers
-^^^^^^^^
+ A TCG *translation block temporary* is a variable which is live
+ throughout the entire translation block, but dies on any exit.
+ These temporaries are allocated explicitly during translation.
-* Depending on the TCG target, pointer size is 32 bit or 64
- bit. The type ``TCG_TYPE_PTR`` is an alias to ``TCG_TYPE_I32`` or
- ``TCG_TYPE_I64``.
+* ``TEMP_EBB``
+
+ A TCG *extended basic block temporary* is a variable which is live
+ throughout an extended basic block, but dies on any exit.
+ These temporaries are allocated explicitly during translation.
+
+Types
+=====
+
+* ``TCG_TYPE_I32``
+
+ A 32-bit integer.
+
+* ``TCG_TYPE_I64``
+
+ A 64-bit integer. For 32-bit hosts, such variables are split into a pair
+ of variables with ``type=TCG_TYPE_I32`` and ``base_type=TCG_TYPE_I64``.
+ The ``temp_subindex`` for each indicates where it falls within the
+ host-endian representation.
+
+* ``TCG_TYPE_PTR``
+
+ An alias for ``TCG_TYPE_I32`` or ``TCG_TYPE_I64``, depending on the size
+ of a pointer for the host.
+
+* ``TCG_TYPE_REG``
+
+ An alias for ``TCG_TYPE_I32`` or ``TCG_TYPE_I64``, depending on the size
+ of the integer registers for the host. This may be larger
+ than ``TCG_TYPE_PTR`` depending on the host ABI.
+
+* ``TCG_TYPE_I128``
+
+ A 128-bit integer. For all hosts, such variables are split into a number
+ of variables with ``type=TCG_TYPE_REG`` and ``base_type=TCG_TYPE_I128``.
+ The ``temp_subindex`` for each indicates where it falls within the
+ host-endian representation.
+
+* ``TCG_TYPE_V64``
+
+ A 64-bit vector. This type is valid only if the TCG target
+ sets ``TCG_TARGET_HAS_v64``.
+
+* ``TCG_TYPE_V128``
+
+ A 128-bit vector. This type is valid only if the TCG target
+ sets ``TCG_TARGET_HAS_v128``.
+
+* ``TCG_TYPE_V256``
+
+ A 256-bit vector. This type is valid only if the TCG target
+ sets ``TCG_TARGET_HAS_v256``.
Helpers
-^^^^^^^
+=======
-* Using the tcg_gen_helper_x_y it is possible to call any function
- taking i32, i64 or pointer types. By default, before calling a helper,
- all globals are stored at their canonical location and it is assumed
- that the function can modify them. By default, the helper is allowed to
- modify the CPU state or raise an exception.
+Helpers are registered in a guest-specific ``helper.h``,
+which is processed to generate ``tcg_gen_helper_*`` functions.
+With these functions it is possible to call a function taking
+i32, i64, i128 or pointer types.
- This can be overridden using the following function modifiers:
+By default, before calling a helper, all globals are stored at their
+canonical location. By default, the helper is allowed to modify the
+CPU state (including the state represented by tcg globals)
+or may raise an exception. This default can be overridden using the
+following function modifiers:
- - ``TCG_CALL_NO_READ_GLOBALS`` means that the helper does not read globals,
- either directly or via an exception. They will not be saved to their
- canonical locations before calling the helper.
+* ``TCG_CALL_NO_WRITE_GLOBALS``
- - ``TCG_CALL_NO_WRITE_GLOBALS`` means that the helper does not modify any globals.
- They will only be saved to their canonical location before calling helpers,
- but they won't be reloaded afterwards.
+ The helper does not modify any globals, but may read them.
+ Globals will be saved to their canonical location before calling helpers,
+ but need not be reloaded afterwards.
- - ``TCG_CALL_NO_SIDE_EFFECTS`` means that the call to the function is removed if
- the return value is not used.
+* ``TCG_CALL_NO_READ_GLOBALS``
- Note that ``TCG_CALL_NO_READ_GLOBALS`` implies ``TCG_CALL_NO_WRITE_GLOBALS``.
+ The helper does not read globals, either directly or via an exception.
+ They will not be saved to their canonical locations before calling
+ the helper. This implies ``TCG_CALL_NO_WRITE_GLOBALS``.
- On some TCG targets (e.g. x86), several calling conventions are
- supported.
+* ``TCG_CALL_NO_SIDE_EFFECTS``
-Branches
-^^^^^^^^
-
-* Use the instruction 'br' to jump to a label.
+ The call to the helper function may be removed if the return value is
+ not used. This means that it may not modify any CPU state nor may it
+ raise an exception.
