+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.
+
+In this document, we use "guest" to specify what architecture we are
+emulating; "target" always means the TCG target, the machine on which
+we are running 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.
+
+An operation with "undefined behavior" may result in a crash.
+
+An operation with "unspecified behavior" shall not crash. However,
+the result may be one of several possibilities so may be considered
+an "undefined result".
+
+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 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.
+
+This 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 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 afterwise.
+- TCG_CALL_NO_SIDE_EFFECTS means that the call to the function is removed if
+ the return value is not used.
+
+Note that TCG_CALL_NO_READ_GLOBALS implies TCG_CALL_NO_WRITE_GLOBALS.
+
+On some TCG targets (e.g. x86), several calling conventions are
+supported.
+
+* Branches:
+
+Use the instruction 'br' to jump to a label.
+
+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

+
+********* Misc
+
+* mov_i32/i64 t0, t1
+
+t0 = t1
+
+Move t1 to t0 (both operands must have the same type).
+
+* ext8s_i32/i64 t0, t1
+ext8u_i32/i64 t0, t1
+ext16s_i32/i64 t0, t1
+ext16u_i32/i64 t0, t1

+
+8, 16 or 32 bit sign/zero extension (both operands must have the same type)
+
+* bswap16_i32/i64 t0, t1
+
+16 bit byte swap on a 32/64 bit value. It assumes that the two/six high order
+bytes are set to zero.
+
+* bswap32_i32/i64 t0, t1
+
+32 bit byte swap on a 32/64 bit value. With a 64 bit value, it assumes that
+the four high order bytes are set to zero.
+
+* bswap64_i64 t0, t1
+
+64 bit byte swap
+
+* discard_i32/i64 t0
+
+Indicate that the value of t0 won't be used later. It is useful to
+force dead code elimination.
+
+* deposit_i32/i64 dest, t1, t2, pos, len
+
+Deposit T2 as a bitfield into T1, placing the result in DEST.
+The bitfield is described by POS/LEN, which are immediate values:
+
+ LEN - the length of the bitfield
+ POS - the position of the first bit, counting from the LSB
+
+For example, pos=8, len=4 indicates a 4-bit field at bit 8.
+This operation would be equivalent to
+
+ dest = (t1 & ~0x0f00) | ((t2 << 8) & 0x0f00)
+
+* trunc_shr_i32 t0, t1, pos
+
+For 64-bit hosts only, right shift the 64-bit input T1 by POS and
+truncate to 32-bit output T0. Depending on the host, this may be
+a simple mov/shift, or may require additional canonicalization.
+
+********* Conditional moves
+
+* setcond_i32/i64 dest, t1, t2, cond
+
+dest = (t1 cond t2)
+
+Set DEST to 1 if (T1 cond T2) is true, otherwise set to 0.
+
+* movcond_i32/i64 dest, c1, c2, v1, v2, cond
+
+dest = (c1 cond c2 ? v1 : v2)
+
+Set DEST to V1 if (C1 cond C2) is true, otherwise set to V2.
+
+********* Type conversions
+
+* ext_i32_i64 t0, t1
+Convert t1 (32 bit) to t0 (64 bit) and does sign extension
+
+* extu_i32_i64 t0, t1

+Truncate t1 (64 bit) to t0 (32 bit)
+
+* concat_i32_i64 t0, t1, t2
+Construct t0 (64-bit) taking the low half from t1 (32 bit) and the high half
+from t2 (32 bit).
+
+* concat32_i64 t0, t1, t2
+Construct t0 (64-bit) taking the low half from t1 (64 bit) and the high half
+from t2 (64 bit).
+
+********* Load/Store
+
+* ld_i32/i64 t0, t1, offset
+ld8s_i32/i64 t0, t1, offset
+ld8u_i32/i64 t0, t1, offset
+ld16s_i32/i64 t0, t1, offset
+ld16u_i32/i64 t0, t1, offset
+ld32s_i64 t0, t1, offset
+ld32u_i64 t0, t1, offset
+
+t0 = read(t1 + offset)
+Load 8, 16, 32 or 64 bits with or without sign extension from host memory.
+offset must be a constant.
+
+* st_i32/i64 t0, t1, offset
+st8_i32/i64 t0, t1, offset
+st16_i32/i64 t0, t1, offset
+st32_i64 t0, t1, offset
+
+write(t0, t1 + offset)
+Write 8, 16, 32 or 64 bits to host memory.
+
+All this opcodes assume that the pointed host memory doesn't correspond
+to a global. In the latter case the behaviour is unpredictable.
+
+********* Multiword arithmetic support
+
+* add2_i32/i64 t0_low, t0_high, t1_low, t1_high, t2_low, t2_high
+* sub2_i32/i64 t0_low, t0_high, t1_low, t1_high, t2_low, t2_high
+
+Similar to add/sub, except that the double-word inputs T1 and T2 are
+formed from two single-word arguments, and the double-word output T0
+is returned in two single-word outputs.
+
+* mulu2_i32/i64 t0_low, t0_high, t1, t2
+
+Similar to mul, except two unsigned inputs T1 and T2 yielding the full
+double-word product T0. The later is returned in two single-word outputs.
+
+* muls2_i32/i64 t0_low, t0_high, t1, t2
+
+Similar to mulu2, except the two inputs T1 and T2 are signed.
+
+********* 64-bit guest 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 t0_low, t0_high, t1_low, t1_high, cond, label
+
+Similar to brcond, except that the 64-bit values T0 and T1
+are formed from two 32-bit arguments.
+
+* setcond2_i32 dest, t1_low, t1_high, t2_low, t2_high, cond
+
+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
+
+* exit_tb 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. Only indices 0 and 1 are valid and tcg_gen_goto_tb may be issued
+at most once with each slot index per TB.
+
+* qemu_ld_i32/i64 t0, t1, flags, memidx
+* qemu_st_i32/i64 t0, t1, flags, memidx
+
+Load data at the guest address t1 into t0, or store data in t0 at guest
+address t1. The _i32/_i64 size applies to the size of the input/output
+register t0 only. The address t1 is always sized according to the guest,
+and the width of the memory operation is controlled by flags.
+
+Both t0 and t1 may be split into little-endian ordered pairs of registers
+if dealing with 64-bit quantities on a 32-bit host.
+
+The memidx selects the qemu tlb index to use (e.g. user or kernel access).
+The flags are the TCGMemOp bits, selecting the sign, width, and endianness
+of the memory access.
+
+For a 32-bit host, qemu_ld/st_i64 is guaranteed to only be used with a
+64-bit memory access specified in flags.
+
+*********
+
+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 guest
+ instructions. There is little performance advantage in using TCG to
+ implement guest instructions taking more than about twenty TCG
+ instructions. Note that this rule of thumb is more applicable to
+ helpers doing complex logic or arithmetic, where the C compiler has
+ scope to do a good job of optimisation; it is less relevant where
+ the instruction is mostly doing loads and stores, and in those cases
+ inline TCG may still be faster for longer sequences.
+
+- The hard limit on the number of TCG instructions you can generate
+ per guest instruction is set by MAX_OP_PER_INSTR in exec-all.h --
+ you cannot exceed this without risking a buffer overrun.
+
+- 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 guest uses it to improve the condition codes optimisation.

+ * 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 next-TB 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 next-TB 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 next-TB pointer we return (falling
+ * back to calling the CPU's set_pc method with tb->pb if no
+ * synchronize_from_tb() method exists).

+TCG Interpreter (TCI) - Copyright (c) 2011 Stefan Weil.
+
+This file is released under the BSD license.
+
+1) Introduction
+
+TCG (Tiny Code Generator) is a code generator which translates
+code fragments ("basic blocks") from target code (any of the
+targets supported by QEMU) to a code representation which
+can be run on a host.
+
+QEMU can create native code for some hosts (arm, hppa, i386, ia64, ppc, ppc64,
+s390, sparc, x86_64). For others, unofficial host support was written.
+
+By adding a code generator for a virtual machine and using an
+interpreter for the generated bytecode, it is possible to
+support (almost) any host.
+
+This is what TCI (Tiny Code Interpreter) does.
+
+2) Implementation
+
+Like each TCG host frontend, TCI implements the code generator in
+tcg-target.c, tcg-target.h. Both files are in directory tcg/tci.
+
+The additional file tcg/tci.c adds the interpreter.
+
+The bytecode consists of opcodes (same numeric values as those used by
+TCG), command length and arguments of variable size and number.
+
+3) Usage
+
+For hosts without native TCG, the interpreter TCI must be enabled by
+
+ configure --enable-tcg-interpreter
+
+If configure is called without --enable-tcg-interpreter, it will
+suggest using this option. Setting it automatically would need
+additional code in configure which must be fixed when new native TCG
+implementations are added.
+
+System emulation should work on any 32 or 64 bit host.
+User mode emulation might work. Maybe a new linker script (*.ld)
+is needed. Byte order might be wrong (on big endian hosts)
+and need fixes in configure.
+
+For hosts with native TCG, the interpreter TCI can be enabled by
+
+ configure --enable-tcg-interpreter
+
+The only difference from running QEMU with TCI to running without TCI
+should be speed. Especially during development of TCI, it was very
+useful to compare runs with and without TCI. Create /tmp/qemu.log by
+
+ qemu-system-i386 -d in_asm,op_opt,cpu -D /tmp/qemu.log -singlestep
+
+once with interpreter and once without interpreter and compare the resulting
+qemu.log files. This is also useful to see the effects of additional
+registers or additional opcodes (it is easy to modify the virtual machine).
+It can also be used to verify native TCGs.
+
+Hosts with native TCG can also enable TCI by claiming to be unsupported:
+
+ configure --cpu=unknown --enable-tcg-interpreter
+
+configure then no longer uses the native linker script (*.ld) for
+user mode emulation.
+
+
+4) Status
+
+TCI needs special implementation for 32 and 64 bit host, 32 and 64 bit target,
+host and target with same or different endianness.
+
+ | host (le) host (be)
+ | 32 64 32 64
+------------+------------------------------------------------------------
+target (le) | s0, u0 s1, u1 s?, u? s?, u?
+32 bit |
+ |
+target (le) | sc, uc s1, u1 s?, u? s?, u?
+64 bit |
+ |
+target (be) | sc, u0 sc, uc s?, u? s?, u?
+32 bit |
+ |
+target (be) | sc, uc sc, uc s?, u? s?, u?
+64 bit |
+ |
+
+System emulation
+s? = untested
+sc = compiles
+s0 = bios works
+s1 = grub works
+s2 = Linux boots
+
+Linux user mode emulation
+u? = untested
+uc = compiles
+u0 = static hello works
+u1 = linux-user-test works
+
+5) Todo list
+
+* TCI is not widely tested. It was written and tested on a x86_64 host
+ running i386 and x86_64 system emulation and Linux user mode.
+ A cross compiled QEMU for i386 host also works with the same basic tests.
+ A cross compiled QEMU for mipsel host works, too. It is terribly slow
+ because I run it in a mips malta emulation, so it is an interpreted
+ emulation in an emulation.
+ A cross compiled QEMU for arm host works (tested with pc bios).
+ A cross compiled QEMU for ppc host works at least partially:
+ i386-linux-user/qemu-i386 can run a simple hello-world program
+ (tested in a ppc emulation).
+
+* Some TCG opcodes are either missing in the code generator and/or
+ in the interpreter. These opcodes raise a runtime exception, so it is
+ possible to see where code must be added.
+
+* The pseudo code is not optimized and still ugly. For hosts with special
+ alignment requirements, it needs some fixes (maybe aligned bytecode
+ would also improve speed for hosts which support byte alignment).
+
+* A better disassembler for the pseudo code would be nice (a very primitive
+ disassembler is included in tcg-target.c).
+
+* It might be useful to have a runtime option which selects the native TCG
+ or TCI, so QEMU would have to include two TCGs. Today, selecting TCI
+ is a configure option, so you need two compilations of QEMU.

+ * This code implements a TCG which does not generate machine code for some
+ * real target machine but which generates virtual machine code for an
+ * interpreter. Interpreted pseudo code is slow, but it works on any host.
+ *
+ * Some remarks might help in understanding the code:
+ *
+ * "target" or "TCG target" is the machine which runs the generated code.
+ * This is different to the usual meaning in QEMU where "target" is the
+ * emulated machine. So normally QEMU host is identical to TCG target.
+ * Here the TCG target is a virtual machine, but this virtual machine must
+ * use the same word size like the real machine.
+ * Therefore, we need both 32 and 64 bit virtual machines (interpreter).
