+Tiny Code Generator - Fabrice Bellard.
+
+1) Introduction
+
+TCG (Tiny Code Generator) began as a generic backend for a C
+compiler. It was simplified to be used in QEMU. It also has its roots
+in the QOP code generator written by Paul Brook.
+
+2) Definitions
+
+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
+from the host, although it is never the case for QEMU.
+
+A TCG "function" corresponds to a QEMU Translated Block (TB).
+
+A TCG "temporary" is a variable only live in a basic
+block. Temporaries are allocated explicitly in each function.
+
+A TCG "local temporary" is a variable only live in a function. Local
+temporaries are allocated explicitly in each function.
+
+A TCG "global" is a variable which is live in all the functions
+(equivalent of a C global variable). They are defined before the
+functions defined. A TCG global can be a memory location (e.g. a QEMU
+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).
+
+A TCG "basic block" corresponds to a list of instructions terminated
+by a branch instruction.
+
+3) Intermediate representation
+
+3.1) Introduction
+
+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.
+
+Each instruction has a fixed number of output variable operands, input
+variable operands and always constant operands.
+
+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
+included in the instruction name. Constants are prefixed with a '$'.
+
+add_i32 t0, t1, t2  (t0 <- t1 + t2)
+
+3.2) Assumptions
+
+* Basic blocks
+
+- Basic blocks end after branches (e.g. brcond_i32 instruction),
+  goto_tb and exit_tb instructions.
+- Basic blocks start after the end of a previous basic block, or at a
+  set_label instruction.
+
+After the end of a basic block, the content of temporaries is
+destroyed, but local temporaries and globals are preserved.
+
+* Floating point types are not supported yet
+
+* Pointers: 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.
+
+* 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 an helper,
+all globals are stored at their canonical location and it is assumed
+that the function can modify them. This can be overriden by the
+TCG_CALL_CONST function modifier. By default, the helper is allowed to
+modify the CPU state or raise an exception. This can be overriden by
+the TCG_CALL_PURE function modifier, in which case the call to the
+function is removed if the return value is not used.
+
+On some TCG targets (e.g. x86), several calling conventions are
+supported.
+
+* Branches:
+
+Use the instruction 'br' to jump to a label. Use 'jmp' to jump to an
+explicit address. Conditional branches can only jump to labels.
+
+3.3) Code Optimizations
+
+When generating instructions, you can count on at least the following
+optimizations:
+
+- Single instructions are simplified, e.g.
+
+   and_i32 t0, t0, $0xffffffff
+
+  is suppressed.
+
+- A liveness analysis is done at the basic block level. The
+  information is used to suppress moves from a dead variable to
+  another one. It is also used to remove instructions which compute
+  dead results. The later is especially useful for condition code
+  optimization in QEMU.
+
+  In the following example:
+
+  add_i32 t0, t1, t2
+  add_i32 t0, t0, $1
+  mov_i32 t0, $1
+
+  only the last instruction is kept.
+
+3.4) Instruction Reference

+
+write(t0, t1 + offset)
+Write 8, 16, 32 or 64 bits to host memory.
+
+********* 64-bit target on 32-bit host support
+
+The following opcodes are internal to TCG.  Thus they are to be implemented by
+32-bit host code generators, but are not to be emitted by guest translators.
+They are emitted as needed by inline functions within "tcg-op.h".
+
+* brcond2_i32 cond, t0_low, t0_high, t1_low, t1_high, label
+
+Similar to brcond, except that the 64-bit values T0 and T1
+are formed from two 32-bit arguments.
+
+* add2_i32 t0_low, t0_high, t1_low, t1_high, t2_low, t2_high
+* sub2_i32 t0_low, t0_high, t1_low, t1_high, t2_low, t2_high
+
+Similar to add/sub, except that the 64-bit inputs T1 and T2 are
+formed from two 32-bit arguments, and the 64-bit output T0
+is returned in two 32-bit outputs.
+
+* mulu2_i32 t0_low, t0_high, t1, t2
+
+Similar to mul, except two 32-bit (unsigned) inputs T1 and T2 yielding
+the full 64-bit product T0.  The later is returned in two 32-bit outputs.
+
+* setcond2_i32 cond, dest, t1_low, t1_high, t2_low, t2_high
+
+Similar to setcond, except that the 64-bit values T1 and T2 are
+formed from two 32-bit arguments.  The result is a 32-bit value.
+
+********* QEMU specific operations
+
+* tb_exit t0
+
+Exit the current TB and return the value t0 (word type).
+
+* goto_tb index
+
+Exit the current TB and jump to the TB index 'index' (constant) if the
+current TB was linked to this TB. Otherwise execute the next
+instructions.
+
+* qemu_ld8u t0, t1, flags
+qemu_ld8s t0, t1, flags
+qemu_ld16u t0, t1, flags
+qemu_ld16s t0, t1, flags
+qemu_ld32 t0, t1, flags
+qemu_ld32u t0, t1, flags
+qemu_ld32s t0, t1, flags
+qemu_ld64 t0, t1, flags
+
+Load data at the QEMU CPU address t1 into t0. t1 has the QEMU CPU address
+type. 'flags' contains the QEMU memory index (selects user or kernel access)
+for example.
+
+Note that "qemu_ld32" implies a 32-bit result, while "qemu_ld32u" and
+"qemu_ld32s" imply a 64-bit result appropriately extended from 32 bits.
+
+* qemu_st8 t0, t1, flags
+qemu_st16 t0, t1, flags
+qemu_st32 t0, t1, flags
+qemu_st64 t0, t1, flags
+
+Store the data t0 at the QEMU CPU Address t1. t1 has the QEMU CPU
+address type. 'flags' contains the QEMU memory index (selects user or
+kernel access) for example.
+
+Note 1: Some shortcuts are defined when the last operand is known to be
+a constant (e.g. addi for add, movi for mov).
+
+Note 2: When using TCG, the opcodes must never be generated directly
+as some of them may not be available as "real" opcodes. Always use the
+function tcg_gen_xxx(args).
+
+4) Backend
+
+tcg-target.h contains the target specific definitions. tcg-target.c
+contains the target specific code.
+
+4.1) Assumptions
+
+The target word size (TCG_TARGET_REG_BITS) is expected to be 32 bit or
+64 bit. It is expected that the pointer has the same size as the word.
+
+On a 32 bit target, all 64 bit operations are converted to 32 bits. A
+few specific operations must be implemented to allow it (see add2_i32,
+sub2_i32, brcond2_i32).
+
+Floating point operations are not supported in this version. A
+previous incarnation of the code generator had full support of them,
+but it is better to concentrate on integer operations first.
+
+On a 64 bit target, no assumption is made in TCG about the storage of
+the 32 bit values in 64 bit registers.
+
+4.2) Constraints
+
+GCC like constraints are used to define the constraints of every
+instruction. Memory constraints are not supported in this
+version. Aliases are specified in the input operands as for GCC.
+
+The same register may be used for both an input and an output, even when
+they are not explicitly aliased.  If an op expands to multiple target
+instructions then care must be taken to avoid clobbering input values.
+GCC style "early clobber" outputs are not currently supported.
+
+A target can define specific register or constant constraints. If an
+operation uses a constant input constraint which does not allow all
+constants, it must also accept registers in order to have a fallback.
+
+The movi_i32 and movi_i64 operations must accept any constants.
+
+The mov_i32 and mov_i64 operations must accept any registers of the
+same type.
+
+The ld/st instructions must accept signed 32 bit constant offsets. It
+can be implemented by reserving a specific register to compute the
+address if the offset is too big.
+
+The ld/st instructions must accept any destination (ld) or source (st)
+register.
+
+4.3) Function call assumptions
+
+- The only supported types for parameters and return value are: 32 and
+  64 bit integers and pointer.
+- The stack grows downwards.
+- The first N parameters are passed in registers.
+- The next parameters are passed on the stack by storing them as words.
+- Some registers are clobbered during the call.
+- The function can return 0 or 1 value in registers. On a 32 bit
+  target, functions must be able to return 2 values in registers for
+  64 bit return type.
+
+5) Recommended coding rules for best performance
+
+- Use globals to represent the parts of the QEMU CPU state which are
+  often modified, e.g. the integer registers and the condition
+  codes. TCG will be able to use host registers to store them.
+
+- Avoid globals stored in fixed registers. They must be used only to
+  store the pointer to the CPU state and possibly to store a pointer
+  to a register window.
+
+- Use temporaries. Use local temporaries only when really needed,
+  e.g. when you need to use a value after a jump. Local temporaries
+  introduce a performance hit in the current TCG implementation: their
+  content is saved to memory at end of each basic block.
+
+- Free temporaries and local temporaries when they are no longer used
+  (tcg_temp_free). Since tcg_const_x() also creates a temporary, you
+  should free it after it is used. Freeing temporaries does not yield
+  a better generated code, but it reduces the memory usage of TCG and
+  the speed of the translation.
+
+- Don't hesitate to use helpers for complicated or seldom used target
+  intructions. There is little performance advantage in using TCG to
+  implement target instructions taking more than about twenty TCG
+  instructions.
+
+- Use the 'discard' instruction if you know that TCG won't be able to
+  prove that a given global is "dead" at a given program point. The
+  x86 target uses it to improve the condition codes optimisation.
