Comparisons are already not promoted if sides are equally signed, but this wasn't true for "unsigned vs constant" case, because constants are preferably parsed as signed.
The change considerably improves generated code for i386 and even more considerably for m68k. Tested on i386-win32.

taddnode.first_addpointer. This will be overridden in the i8086 code generator
in order to implement huge pointer arithmetic.

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

+ added charfarpointertype and charnearpointertype to symdef
* the system unit compiles in the i8086 compact memory model now

since it performs exactly the same thing as the generic signed 32-bit handling
in the else clause (regardless of whether cpuneedsmulhelper is defined or not)

defcmp.pas:
+ add new function "def_is_related" which combines the "is_related" overloads of "tobjectdef", "trecorddef" and "tstringdef" (it returns "false" for other def types which is what "tdef.is_related" did)
* compare_defs_ext & compatible_childmethod_resultdef: change call from "x.is_related" to "def_is_related(x,...)"
symtype.pas, tdef:
- remove "is_related" method
symdef.pas:
- remove "is_related" in "tobjectdef", "trecorddef" and "tstringdef"
* tobjectdef.needs_inittable: for checking whether a Corba interface somehow inherits from a IInterface don't use "is_related" anymore (we want to avoid the dependency after all), but mimic the necessary functionality of "def_is_related"
htypechk.pas, nadd.pas, ncal.pas, ncnv.pas, ngtcon.pas, nld.pas, optvirt.pas, pdecobj.pas, pdecvar.pas, pexpr.pas, pgenutil.pas:
* change call from "x.is_related" to "def_is_related(x,...)"
symtable.pas
+ use unit defcmp
* change call from "x.is_related" to "def_is_related(x,...)"
jvm/njvmcnv.pas, jvm/njvmflw.pas:
* change call from "x.is_related" to "def_is_related(x,...)"

type with a non-default code page
TODO: ensure that string constants typecasted to ansistring become
ansistrings rather than typeless string constants
git-svn-id: trunk@25207 -
CP_ACP (defaultsystemcodepage), because if all input strings have the
same code page then the result should also have that code page if it's
assigned to a rawbytestring rather than getting defaultsystemcodepage
* do not consider empty strings to determine the code page of the result
in fpc_AnsiStr_Concat_multi(), because that will cause a different
result than when using a sequence of fpc_AnsiStr_Concat() calls (it
ignores empty strings to determine the result code page) and it's also
slower
* do not consider the run time code page of the destination string in
fpc_AnsiStr_Concat(_multi)() because Delphi does not do so either. This
was introduced in r19118, probably to hide another bug
+ test
git-svn-id: branches/cpstrrtl@25143 -
nadd.pas, taddnode:
+ add new constructor "create_internal" which adds "nf_internal" to the node's "flags"
* pass_typecheck_internal: allow pointer comparisons other than "=" and "<>" for nodes which have "nf_internal" set
psub.pas, generate_bodyentry_block:
* create the addnode using "create_internal" instead of "create" to allow the pointer comparison
+ added test
