df60309d96 * m68k: fixed the last remaining warning and removed "$WARNINGS OFF" directive.

e5656a6f7e m68k assembler reader: fixed parsing of slash-separated movem/fmovem register lists. only the first register was stored.

1678fcdc2d - m68k assembler reader: removed Oper.InitRef which was causing failure of tbs/tb0142.pp and, in general, making impossible calls/jumps to non-alias procedure names.

b91d965096 * m68k: initial support for ROL/ROR operations, defining 'cpurox' for CPU target can actually enable them. However it cannot be done outright because these instructions do not exits on Coldfire, and internal processing of RoX,Sar,BsX, etc. can not yet be switched depending on CPU subtype.

15e374f3c6 * m68k: fixed comparison of small sets, it should not modify sides. tw18013 is now correct when compiled with -O2.

0262514939 * m68k: Transform 32-bit div/mod nodes into helper calls during pass 1. This is consistent with the way other targets do it, and results in pretty much nicer code.

85c0ba96e2 * tm68knotnode brought up to speed: 
- removed code for everything but booleans (it is handled perfectly well by generic code)
 + operate directly on references when possible
 + added handling for 64-bit data.

4df49964ca * tcg68k.a_op_reg_reg: renamed parameters 'reg1' and 'reg2' to 'src' and 'dst' to make it clear what's what. 
* tcg68k.fixref method made public.

c2ab16c320 - m68k: dropped t68kaddnode.second_cmpboolean, apparently its presence just breaks tbs/tb0246 without any value added.

3851c1f494 - m68k: removed a_loadmm_* methods, no need to override because they produce internal error already in base class.

acd3ea8750 * m68k: Fixed parameter passing to conform to ABI: 
* records are passed by value
  * records with size of 1,2 or 4 are returned in registers
  * parameters with size<4 are justified on the stack according to big-endian target

Now everything except floating-point parameters is compatible with C code compiled with "-malign-int -mrtd".
Compatibility with "-mno-align-int" is achievable by changing target_info.maxCrecordalign to 2, but doings so causes a lot more troubles because RTL (incorrectly) assumes that records declared with {$PACKRECORDS C} are aligned to pointer size.

+ Reuse parameter locations. Since everything is passed on stack, it reduces code size quite a bit.
- tm68kparamanager.getintparaloc removed, generic implementation has been tested and works as expected.

cpu-specific descendants (unfortunately causes some duplication, but the

b57c95043f + support overriding tdef/tsym methods with target-specific functionality: 
o made all (non-abstract) tdef and tsym constructors virtual
   o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
     class
   o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
     class from the base classes, and initialises the c*def/c*sym classes with
     them. This is done so that the llvm target will be able to derive from
     the tcpu*def/sym classes without umpteen ifdefs, and it also means that
     the WPO can devirtualise everything because the c* variables are only
     initialised with one class type
   o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
     calls
