+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
+
+  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.
