 * \mainpage
 *      There are 2 representations of the binary code in the decompiler:
 *        - microcode: processor instructions are translated into it and then
 *                     the decompiler optimizes and transforms it
 *        - ctree:     ctree is built from the optimized microcode and represents
 *                     AST-like tree with C statements and expressions. It can
 *                     be printed as C code.
 *
 *      Microcode is represented by the following classes:
 *       - mba_t keeps general info about the decompiled code and
 *                     array of basic blocks. usually mba_t is named 'mba'
 *       - mblock_t    a basic block. includes list of instructions
 *       - minsn_t     an instruction. contains 3 operands: left, right, and
 *                     destination
 *       - mop_t       an operand. depending on its type may hold various info
 *                     like a number, register, stack variable, etc.
 *       - mlist_t     list of memory or register locations; can hold vast areas
 *                     of memory and multiple registers. this class is used
 *                     very extensively in the decompiler. it may represent
 *                     list of locations accessed by an instruction or even
 *                     an entire basic block. it is also used as argument of
 *                     many functions. for example, there is a function
 *                     that searches for an instruction that refers to a mlist_t.
 
 *      See https://www.hex-rays.com/blog/microcode-in-pictures for some pictures.
 *
 *      Ctree is represented by:
 *       - cfunc_t     keeps general info about the decompiled code, including a
 *                     pointer to mba_t. deleting cfunc_t will delete
 *                     mba_t too (however, decompiler returns cfuncptr_t,
 *                     which is a reference counting object and deletes the
 *                     underlying function as soon as all references to it go
 *                     out of scope). cfunc_t has 'body', which represents the
 *                     decompiled function body as cinsn_t.
 *       - cinsn_t     a C statement. can be a compound statement or any other
 *                     legal C statements (like if, for, while, return,
 *                     expression-statement, etc). depending on the statement
 *                     type has pointers to additional info. for example, the
 *                     'if' statement has poiner to cif_t, which holds the
 *                     'if' condition, 'then' branch, and optionally 'else'
 *                     branch. Please note that despite of the name cinsn_t
 *                     we say "statements", not "instructions". For us
 *                     instructions are part of microcode, not ctree.
 *       - cexpr_t     a C expression. is used as part of a C statement, when
 *                     necessary. cexpr_t has 'type' field, which keeps the
 *                     expression type.
 *       - citem_t     a base class for cinsn_t and cexpr_t, holds common info
 *                     like the address, label, and opcode.
 *       - cnumber_t   a constant 64-bit number. in addition to its value also
 *                     holds information how to represent it: decimal, hex, or
 *                     as a symbolic constant (enum member). please note that
 *                     numbers are represented by another class (mnumber_t)
 *                     in microcode.
 
 *      See https://www.hex-rays.com/blog/hex-rays-decompiler-primer
 *      for some pictures and more details.
 *
 *      Both microcode and ctree use the following class:
 *       - lvar_t      a local variable. may represent a stack or register
 *                     variable. a variable has a name, type, location, etc.
 *                     the list of variables is stored in mba->vars.
 *       - lvar_locator_t holds a variable location (vdloc_t) and its definition
 *                     address.
 *       - vdloc_t     describes a variable location, like a register number,
 *                     a stack offset, or, in complex cases, can be a mix of
 *                     register and stack locations. very similar to argloc_t,
 *                     which is used in ida. the differences between argloc_t
 *                     and vdloc_t are:
 *                       - vdloc_t never uses ARGLOC_REG2
 *                       - vdloc_t uses micro register numbers instead of
 *                         processor register numbers
 *                       - the stack offsets are never negative in vdloc_t, while
 *                         in argloc_t there can be negative offsets
 *
 *      The above are the most important classes in this header file. There are
 *      many auxiliary classes, please see their definitions in the header file.

/*!
 * \page vmpage Virtual Machine used by Microcode
 *      We can imagine a virtual micro machine that executes microcode.
 *      This virtual micro machine has many registers.
 *      Each register is 8 bits wide. During translation of processor
 *      instructions into microcode, multibyte processor registers are mapped
 *      to adjacent microregisters. Processor condition codes are also
 *      represented by microregisters. The microregisters are grouped
 *      into following groups:
 *       - 0..7: condition codes
 *       - 8..n: all processor registers (including fpu registers, if necessary)
 *               this range may also include temporary registers used during
 *               the initial microcode generation
 *       - n.. : so called kernel registers; they are used during optimization
 *               see is_kreg()
 *
 *      Each micro-instruction (minsn_t) has zero to three operands.
 *      Some of the possible operands types are:
 *        - immediate value
 *        - register
 *        - memory reference
 *        - result of another micro-instruction
 *
 *      The operands (mop_t) are l (left), r (right), d (destination).
 *      An example of a microinstruction:
 *
 *              add r0.4, #8.4, r2.4
 *
 *      which means 'add constant 8 to r0 and place the result into r2'.
 *      where
 *       - the left operand is 'r0', its size is 4 bytes (r0.4)
 *       - the right operand is a constant '8', its size is 4 bytes (#8.4)
 *       - the destination operand is 'r2', its size is 4 bytes (r2.4)
 *      Note that 'd' is almost always the destination but there are exceptions.
 *      See mcode_modifies_d(). For example, stx does not modify 'd'.
 *      See the opcode map below for the list of microinstructions and their
 *      operands. Most instructions are very simple and do not need
 *      detailed explanations. There are no side effects in microinstructions.
 *
 *      Each operand has a size specifier. The following sizes can be used in
 *      practically all contexts: 1, 2, 4, 8, 16 bytes. Floating types may have
 *      other sizes. Functions may return objects of arbitrary size, as well as
 *      operations upon UDT's (user-defined types, i.e. are structs and unions).
 *
 *      Memory is considered to consist of several segments.
 *      A memory reference is made using a (selector, offset) pair.
 *      A selector is always 2 bytes long. An offset can be 4 or 8 bytes long,
 *      depending on the bitness of the target processor.
 *      Currently the selectors are not used very much. The decompiler tries to
 *      resolve (selector, offset) pairs into direct memory references at each
 *      opportunity and then operates on mop_v operands. In other words,
 *      while the decompiler can handle segmented memory models, internally
 *      it still uses simple linear addresses.
 *
 *      The following memory regions are recognized:
 *        - GLBLOW   global memory: low part, everything below the stack
 *        - LVARS    stack: local variables
 *        - RETADDR  stack: return address
 *        - SHADOW   stack: shadow arguments
 *        - ARGS     stack: regular stack arguments
 *        - GLBHIGH  global memory: high part, everything above the stack
 *      Any stack region may be empty. Objects residing in one memory region
 *      are considered to be completely distinct from objects in other regions.
 *      We allocate the stack frame in some memory region, which is not
 *      allocated for any purposes in IDA. This permits us to use linear addresses
 *      for all memory references, including the stack frame.
 *
 *      If the operand size is bigger than 1 then the register
 *      operand references a block of registers. For example:
 *
 *              ldc   #1.4, r8.4
 *
 *      loads the constant 1 to registers 8, 9, 10, 11:
 *
 *               #1  ->  r8
 *               #0  ->  r9
 *               #0  ->  r10
 *               #0  ->  r11
 *
 *      This example uses little-endian byte ordering.
 *      Big-endian byte ordering is supported too. Registers are always little-
 *      endian, regardless of the memory endianness.
 *
 *      Each instruction has 'next' and 'prev' fields that are used to form
 *      a doubly linked list. Such lists are present for each basic block (mblock_t).
 *      Basic blocks have other attributes, including:
 *        - dead_at_start: list of dead locations at the block start
 *        - maybuse:  list of locations the block may use
 *        - maybdef:  list of locations the block may define (or spoil)
 *        - mustbuse: list of locations the block will certainly use
 *        - mustbdef: list of locations the block will certainly define
 *        - dnu:      list of locations the block will certainly define
 *                    but will not use (registers or non-aliasable stkack vars)
 *
 *      These lists are represented by the mlist_t class. It consists of 2 parts:
 *        - rlist_t: list of microregisters (possibly including virtual stack locations)
 *        - ivlset_t: list of memory locations represented as intervals
 *                    we use linear addresses in this list.
 *      The mlist_t class is used quite often. For example, to find what an operand
 *      can spoil, we build its 'maybe-use' list. Then we can find out if this list
 *      is accessed using the is_accessed() or is_accessed_globally() functions.
 *
 *      All basic blocks of the decompiled function constitute an array called
 *      mba_t (array of microblocks). This is a huge class that has too
 *      many fields to describe here (some of the fields are not visible in the sdk)
 *      The most importants ones are:
 *        - stack frame: frregs, stacksize, etc
 *        - memory: aliased, restricted, and other ranges
 *        - type: type of the current function, its arguments (argidx) and
 *                local variables (vars)
 *        - natural: array of pointers to basic blocks. the basic blocks
 *                   are also accessible as a doubly linked list starting from 'blocks'.
 *        - bg: control flow graph. the graph gives access to the use-def
 *                   chains that describe data dependencies between basic blocks
 *
 *   Facilities for debugging decompiler plugins:
 *      Many decompiler objects have a member function named dstr().
 *      These functions create a text representation of the object and return
 *      a pointer to it. They are very convenient to use in a debugger instead of
 *      inspecting class fields manually. The mba_t object does not have the
 *      dstr() function because its text representation very long. Instead, we
 *      provide the mba_t::dump_mba() and mba_t::dump() functions.
 *
 *      To ensure that your plugin manipulates the microcode in a correct way,
 *      please call mba_t::verify() before returning control to the decompiler.

  There is a detail that may add confusion when working with stack variables.
  The decompiler does not use the same stack offsets as IDA.
  The picture above should explain the difference:
  - IDA stkoffs are displayed on the left, decompiler stkoffs - on the right
  - Decompiler stkoffs are always >= 0
  - IDA stkoff==0 corresponds to stkoff==tmpstk_size in the decompiler
  - See stkoff_vd2ida and stkoff_ida2vd below to convert IDA stkoffs to vd stkoff
