394dfdd220 * ensure that all initialised items have a type (and only one):
o remove the accompanying tdef operands from tai operands, because such
     tai operands should have a tdef already
   o check that every queued tai is a tai_simpletypedconst (which have a
     type)
   o wrap queued bitcast/getelementptr tai instances with a
     tai_simpletypedconst

63305cc2e6 + added directive {$HUGEPOINTERARITHMETICNORMALIZATION} to control the
cs_hugeptr_arithmetic_normalization local setting
+ added the cs_hugeptr_comparison_normalization local setting and corresponding
  directive {$HUGEPOINTERCOMPARISONNORMALIZATION} to set it
* the {HUGEPOINTERNORMALIZATION} changed to set both of the huge pointer
  normalization settings, according to the specified compiler type ('BORLANDC',
  'MICROSOFTC' or 'WATCOMC')

8afffdb176 * moved get_string_symofs() to a virtual class method of
ttai_typedconstbuilder so that it can be overridden by other platforms

    have labels in the middle of a declaration on that platform

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

a284902813 * emit the current offset when flushing tasmsymbols in the
ttai_lowleveltypedconstbuilder
   o set the offset to 0 in the llvm constbuilder before calling
     the lowlevel one, because it incorporates this offset already
     via getelementptr instructions

e0c1c4d3bf + support for merging multiple tai_strings/tai_consts emitted as part of the
same string constant to be merged together into a single tai_string
    (required to efficiently represent string constants in llvm assembler
     --i.e., without splitting them into bytes--, while keeping the
     flexibility in the typed constant parser to mix individual elements
     and strings)

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

1a77bc952e * immediate write out partial string respresentations of instructions
rather than first concatenating everything, because in case of
    instructions that have other tai as operands we have to ensure that
    all previous output is flushed before the tai-operand is evaluated
    (and written/flushed)
