-- * Current position, p, is now last read index instead of a pointer
--
-- Not implemented:
-- * luaZ_lookahead: used only in lapi.c:lua_load to detect binary chunk
-- * luaZ_read: used only in lundump.c:ezread to read +1 bytes
-- * luaZ_openspace: dropped; let Lua handle buffers as strings (used in
--   lundump.c:LoadString & lvm.c:luaV_concat)
-- * luaZ buffer macros: dropped; buffers are handled as strings
-- * lauxlib.c:getF reader implementation has an extraline flag to

--[[--------------------------------------------------------------------
-- Notes:
-- * intended to 'imitate' llex.c code; performance is not a concern
-- * tokens are strings; code structure largely retained
-- * deleted stuff (compared to llex.c) are noted, comments retained
-- * nextc() returns the currently read character to simplify coding
--   here; next() in llex.c does not return anything
-- * compatibility code is marked with "--#" comments
--
-- Added:
-- * luaX:chunkid (function luaO_chunkid from lobject.c)
-- * luaX:str2d (function luaO_str2d from lobject.c)
-- * luaX.LUA_QS used in luaX:lexerror (from luaconf.h)
-- * luaX.LUA_COMPAT_LSTR in luaX:read_long_string (from luaconf.h)
-- * luaX.MAX_INT used in luaX:inclinenumber (from llimits.h)
--
-- To use the lexer:
-- (1) luaX:init() to initialize the lexer
-- (2) luaX:setinput() to set the input stream to lex
-- (3) call luaX:next() or luaX:luaX:lookahead() to get tokens,
--     until "TK_EOS": luaX:next()
-- * since EOZ is returned as a string, be careful when regexp testing
--
-- Not implemented:
-- * luaX_newstring: not required by this Lua implementation
-- * buffer MAX_SIZET size limit (from llimits.h) test not implemented
--   in the interest of performance
-- * locale-aware number handling is largely redundant as Lua's
--   tonumber() function is already capable of this
--
-- Changed in 5.1.x:
-- * TK_NAME token order moved down
-- * string representation for TK_NAME, TK_NUMBER, TK_STRING changed
-- * token struct renamed to lower case (LS -> ls)
-- * LexState struct: removed nestlevel, added decpoint
-- * error message functions have been greatly simplified
-- * token2string renamed to luaX_tokens, exposed in llex.h
-- * lexer now handles all kinds of newlines, including CRLF
-- * shbang first line handling removed from luaX:setinput;
--   it is now done in lauxlib.c (luaL_loadfile)
-- * next(ls) macro renamed to nextc(ls) due to new luaX_next function
-- * EXTRABUFF and MAXNOCHECK removed due to lexer changes
-- * checkbuffer(ls, len) macro deleted
-- * luaX:read_numeral now has 3 support functions: luaX:trydecpoint,
--   luaX:buffreplace and (luaO_str2d from lobject.c) luaX:str2d
-- * luaX:read_numeral is now more promiscuous in slurping characters;
--   hexadecimal numbers was added, locale-aware decimal points too
-- * luaX:skip_sep is new; used by luaX:read_long_string
-- * luaX:read_long_string handles new-style long blocks, with some
--   optional compatibility code
-- * luaX:llex: parts changed to support new-style long blocks
-- * luaX:llex: readname functionality has been folded in
-- * luaX:llex: removed test for control characters

--[[--------------------------------------------------------------------
-- Notes:
-- * some unused C code that were not converted are kept as comments
-- * LUA_COMPAT_VARARG option changed into a comment block
-- * for value/size specific code added, look for 'NOTE: '
--
-- Not implemented:
-- * luaX_newstring not needed by this Lua implementation
-- * luaG_checkcode() in assert is not currently implemented
--
-- Added:
-- * some constants added from various header files
-- * luaY.LUA_QS used in error_expected, check_match (from luaconf.h)
-- * luaY:LUA_QL needed for error messages (from luaconf.h)
-- * luaY:growvector (from lmem.h) -- skeleton only, limit checking
-- * luaY.SHRT_MAX (from <limits.h>) for registerlocalvar
-- * luaY:newproto (from lfunc.c)
-- * luaY:int2fb (from lobject.c)
-- * NOTE: HASARG_MASK, for implementing a VARARG_HASARG bit operation
-- * NOTE: value-specific code for VARARG_NEEDSARG to replace a bitop
--
-- Changed in 5.1.x:
-- * various code changes are not detailed...
-- * names of constants may have changed, e.g. added a LUAI_ prefix
-- * struct expkind: added VKNUM, VVARARG; VCALL's info changed?
-- * struct expdesc: added nval
-- * struct FuncState: upvalues data type changed to upvaldesc
-- * macro hasmultret is new
-- * function checklimit moved to parser from lexer
-- * functions anchor_token, errorlimit, checknext are new
-- * checknext is new, equivalent to 5.0.x's check, see check too
-- * luaY:next and luaY:lookahead moved to lexer
-- * break keyword no longer skipped in luaY:breakstat
-- * function new_localvarstr replaced by new_localvarliteral
-- * registerlocalvar limits local variables to SHRT_MAX
-- * create_local deleted, new_localvarliteral used instead
-- * constant LUAI_MAXUPVALUES increased to 60
-- * constants MAXPARAMS, LUA_MAXPARSERLEVEL, MAXSTACK removed
-- * function interface changed: singlevaraux, singlevar
-- * enterlevel and leavelevel uses nCcalls to track call depth
-- * added a name argument to main entry function, luaY:parser
-- * function luaY_index changed to yindex
-- * luaY:int2fb()'s table size encoding format has been changed
-- * luaY:log2() no longer needed for table constructors
-- * function code_params deleted, functionality folded in parlist
-- * vararg flags handling (is_vararg) changes; also see VARARG_*
-- * LUA_COMPATUPSYNTAX section for old-style upvalues removed
-- * repeatstat() calls chunk() instead of block()
-- * function interface changed: cond, test_then_block
-- * while statement implementation considerably simplified; MAXEXPWHILE
--   and EXTRAEXP no longer required, no limits to the complexity of a
--   while condition
-- * repeat, forbody statement implementation has major changes,
--   mostly due to new scoping behaviour of local variables
-- * OPR_MULT renamed to OPR_MUL

-- Notes:
-- * one function manipulate a pointer argument with a simple data type
--   (can't be emulated by a table, ambiguous), now returns that value:
--   luaK:concat(fs, l1, l2)
-- * luaM_growvector uses the faux luaY:growvector, for limit checking
-- * some function parameters changed to boolean, additional code
--   translates boolean back to 1/0 for instruction fields
--
-- Not implemented:
-- * NOTE there is a failed assert in luaK:addk, a porting problem
--
-- Added:
-- * constant MAXSTACK from llimits.h
-- * luaK:ttisnumber(o) (from lobject.h)
-- * luaK:nvalue(o) (from lobject.h)
-- * luaK:setnilvalue(o) (from lobject.h)
-- * luaK:setnvalue(o, x) (from lobject.h)
-- * luaK:setbvalue(o, x) (from lobject.h)
-- * luaK:sethvalue(o, x) (from lobject.h), parameter L deleted
-- * luaK:setsvalue(o, x) (from lobject.h), parameter L deleted
-- * luaK:numadd, luaK:numsub, luaK:nummul, luaK:numdiv, luaK:nummod,
--   luaK:numpow, luaK:numunm, luaK:numisnan (from luaconf.h)
-- * copyexp(e1, e2) added in luaK:posfix to copy expdesc struct
--
-- Changed in 5.1.x:
-- * enum BinOpr has a new entry, OPR_MOD
-- * enum UnOpr has a new entry, OPR_LEN
-- * binopistest, unused in 5.0.x, has been deleted
-- * macro setmultret is new
-- * functions isnumeral, luaK_ret, boolK are new
-- * funcion nilK was named nil_constant in 5.0.x
-- * function interface changed: need_value, patchtestreg, concat
-- * TObject now a TValue
-- * functions luaK_setreturns, luaK_setoneret are new
-- * function luaK:setcallreturns deleted, to be replaced by:
--   luaK:setmultret, luaK:ret, luaK:setreturns, luaK:setoneret
-- * functions constfolding, codearith, codecomp are new
-- * luaK:codebinop has been deleted
-- * function luaK_setlist is new

--[[--------------------------------------------------------------------
-- Notes:
-- * WARNING! byte order (little endian) and data type sizes for header
--   signature values hard-coded; see luaU:header
-- * chunk writer generators are included, see below
-- * one significant difference is that instructions are still in table
--   form (with OP/A/B/C/Bx fields) and luaP:Instruction() is needed to
--   convert them into 4-char strings
--
-- Not implemented:
-- * DumpVar, DumpMem has been removed
-- * DumpVector folded into folded into DumpDebug, DumpCode
--
-- Added:
-- * for convenience, the following two functions have been added:
--   luaU:make_setS: create a chunk writer that writes to a string
--   luaU:make_setF: create a chunk writer that writes to a file
--   (lua.h contains a typedef for lua_Writer/lua_Chunkwriter, and
--    a Lua-based implementation exists, writer() in lstrlib.c)
-- * luaU:ttype(o) (from lobject.h)
-- * for converting number types to its binary equivalent:
--   luaU:from_double(x): encode double value for writing
--   luaU:from_int(x): encode integer value for writing
--     (error checking is limited for these conversion functions)
--     (double conversion does not support denormals or NaNs)
--
-- Changed in 5.1.x:
-- * the dumper was mostly rewritten in Lua 5.1.x, so notes on the
--   differences between 5.0.x and 5.1.x is limited
-- * LUAC_VERSION bumped to 0x51, LUAC_FORMAT added
-- * developer is expected to adjust LUAC_FORMAT in order to identify
--   non-standard binary chunk formats
-- * header signature code is smaller, has been simplified, and is
--   tested as a single unit; its logic is shared with the undumper
-- * no more endian conversion, invalid endianness mean rejection
-- * opcode field sizes are no longer exposed in the header
-- * code moved to front of a prototype, followed by constants
-- * debug information moved to the end of the binary chunk, and the
--   relevant functions folded into a single function
-- * luaU:dump returns a writer status code
-- * chunk writer now implements status code because dumper uses it
-- * luaU:endianness removed

===========================================================================
  We assume that instructions are unsigned numbers.
  All instructions have an opcode in the first 6 bits.
  Instructions can have the following fields:
        'A' : 8 bits
        'B' : 9 bits
        'C' : 9 bits
        'Bx' : 18 bits ('B' and 'C' together)
        'sBx' : signed Bx

  A signed argument is represented in excess K; that is, the number
  value is the unsigned value minus K. K is exactly the maximum value
  for that argument (so that -max is represented by 0, and +max is
  represented by 2*max), which is half the maximum for the corresponding
  unsigned argument.

  Notes:
  (*) In OP_CALL, if (B == 0) then B = top. C is the number of returns - 1,
      and can be 0: OP_CALL then sets 'top' to last_result+1, so
      next open instruction (OP_CALL, OP_RETURN, OP_SETLIST) may use 'top'.
  (*) In OP_VARARG, if (B == 0) then use actual number of varargs and
      set top (like in OP_CALL with C == 0).
  (*) In OP_RETURN, if (B == 0) then return up to 'top'
  (*) In OP_SETLIST, if (B == 0) then B = 'top';
      if (C == 0) then next 'instruction' is real C
  (*) For comparisons, A specifies what condition the test should accept
