+We can use 2 alternative versions of code:

+  Byte temp[8];
+  Last byte of marker (e8/e9/[0f]8x) can be written to temp[] buffer.
+  Encoder writes last byte of marker (e8/e9/[0f]8x) to dest, only in conjunction
+  with writing branch symbol to range coder in same Bcj2Enc_Encode_2() call.
+
+2) marker version:
+  UInt32 CBcj2Enc::context
+  Byte CBcj2Enc::temp[4];
+  MARKER_FLAG in CBcj2Enc::context shows that CBcj2Enc::context contains finded marker.
+  it's allowed that
+    one call of Bcj2Enc_Encode_2() writes last byte of marker (e8/e9/[0f]8x) to dest,
+    and another call of Bcj2Enc_Encode_2() does offset conversion.
+    So different values of (fileIp) and (fileSize) are possible
+    in these different Bcj2Enc_Encode_2() calls.
+
+Also marker version requires additional if((v & MARKER_FLAG) == 0) check in main loop.

+  If multi-block (solid) encoding is used,
+    and BCJ2_ENC_FINISH_MODE_END_BLOCK is used for each sub-stream.
+    and (0f) is last byte of previous sub-stream
+    and (8x) is first byte of current sub-stream
+  then (0f 8x) pair is treated as marker by BCJ2 encoder and decoder.
+  BCJ2 encoder can converts 32-bit offset for that (0f 8x) cortage,
+  if that offset meets limit requirements.
+  If encoder allows 32-bit offset conversion for such overlap case,
+  then the data in 3 uncompressed BCJ2 streams for some sub-stream
+  can depend from data of previous sub-stream.

 /*
-These functions convert relative addresses to absolute addresses
-in CALL instructions to increase the compression ratio.
-  
-  In:
-    data     - data buffer
-    size     - size of data
-    ip       - current virtual Instruction Pinter (IP) value
-    state    - state variable for x86 converter
-    encoding - 0 (for decoding), 1 (for encoding)
-  
-  Out:
-    state    - state variable for x86 converter
+These functions convert data that contain CPU instructions.
+Each such function converts relative addresses to absolute addresses in some
+branch instructions: CALL (in all converters) and JUMP (X86 converter only).
+Such conversion allows to increase compression ratio, if we compress that data.
+
+There are 2 types of converters:
+  Byte * Conv_RISC (Byte *data, SizeT size, UInt32 pc);
+  Byte * ConvSt_X86(Byte *data, SizeT size, UInt32 pc, UInt32 *state);
+Each Converter supports 2 versions: one for encoding
+and one for decoding (_Enc/_Dec postfixes in function name).
 
-  Returns:
-    The number of processed bytes. If you call these functions with multiple calls,
-    you must start next call with first byte after block of processed bytes.
+In params:
+  data  : data buffer
+  size  : size of data
+  pc    : current virtual Program Counter (Instruction Pinter) value
+In/Out param:
+  state : pointer to state variable (for X86 converter only)
+
+Return:
+  The pointer to position in (data) buffer after last byte that was processed.
+  If the caller calls converter again, it must call it starting with that position.
+  But the caller is allowed to move data in buffer. so pointer to
+  current processed position also will be changed for next call.
+  Also the caller must increase internal (pc) value for next call.
   
+Each converter has some characteristics: Endian, Alignment, LookAhead.
   Type   Endian  Alignment  LookAhead

-  size must be >= Alignment + LookAhead, if it's not last block.
-  If (size < Alignment + LookAhead), converter returns 0.
-
-  Example:
+  (data) must be aligned for (Alignment).
+  processed size can be calculated as:
+    SizeT processed = Conv(data, size, pc) - data;
+  if (processed == 0)
+    it means that converter needs more data for processing.
+  If (size < Alignment + LookAhead)
+    then (processed == 0) is allowed.
 
-    UInt32 ip = 0;
-    for ()
-    {
-      ; size must be >= Alignment + LookAhead, if it's not last block
-      SizeT processed = Convert(data, size, ip, 1);
-      data += processed;
-      size -= processed;
-      ip += processed;
-    }
+Example code for conversion in loop:
+  UInt32 pc = 0;
+  size = 0;
+  for (;;)
+  {
+    size += Load_more_input_data(data + size);
+    SizeT processed = Conv(data, size, pc) - data;
+    if (processed == 0 && no_more_input_data_after_size)
+      break; // we stop convert loop
+    data += processed;
+    size -= processed;
+    pc += processed;
