15ff2c1236 * m68k: Fixed name of ELF interpreter, and updated cprt0.as to somewhat working state. Now a "hello world" program using libc can be linked and launched, but anything more complex needs another round of fixing the parameter passing code, in order to get the stack properly balanced.

441e6c6083 Fix for Mantis #26177. Use the correct value for the method data when using a method pointer of a type or record helper. 
Please note that Delphi has the exact same bug as we have and thus code working in FPC will not work in Delphi.
Additionally taking the method address of a local variable or a local/global constant for a method pointer is dangerous as the variable (in case of constants is a temporary local variable) will go out of scope once the containing procedure/function/method exits!

ncgld.pas, tcgloadnode.pass_generate_code:
  * only use the value of Self if it is an implicit pointer object (class instance) or a class reference, but not for everything else (objects, records, primitive types)

30be5d8d33 As discussed on core enable the abstract class construction warning by default and also make it controllable with {$warn constructing_abstract ...}. 
* scandir.pas, dir_warn: also adjust the message state for type_w_instance_abstract_class if the identifier is CONSTRUCTING_ABSTRACT
* msg/errore.msg: enable type_w_instance_abstract_class by default

* msgidx.inc, msgtxt.inc: updated

a7a9440692 Add a new warning message that is generated if an instance of an abstract class is created. This message is disabled by default, but can be switched on by using {$warn 4122 on} or {$warn 4122 error}. 
Please note that this warning won't be triggered if an instance of that class is created using a class variable of that class type as the compiler can not know the type contained in the variable at compile time (see also the added test).

+ msg/errore.msg: added disabled message which informs about the instantiation of an abstract class
* pexpr.pas, do_member_read: generate the message if we have a constructor call for an abstract class using a loadvmtaddrnode (thus the type name is used and not a class variable)

* msg{idx,txt}.inc: updated

+ added test

23a20f0e50 * m68k: fixed setjmp/longjmp: 
* Data registers have to be saved/restored using 'move.l', because 'move' without suffix assumes 16-bit size.
  * setjmp must behave as a regular function w.r.t. removing its argument from the stack.

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.
