99b4389297 * fixed tbs/tb0607 for 64 bit targets: there the nf_internal flag isn't set
for cardinal-cardinal. Now treat the result of any sub node as potentially
    negative.

e704dd8d74 * treat "u32bit-u32bit" as a signed value when removing automatic
64 bit upcasts, as the result can be negative when evaluated in
    64 bit (reported on irc, please file bug reports)

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

798bb91e90 Extract tdef.is_related plus its overrides in tobjectdef, trecorddef and tstringdef into a new function def_is_related in unit defcmp.
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:

symdef.pas:
  - tobjectdef: remove method "find_implemented_interface"

90d66595c2 * typecheck_real_to_currency: generate inline round() node instead of direct call to fpc_round_real, this allows target-specific processing to take place and possibly emit more efficient code.
* Provide x86_64 SSE versions of fpc_trunc_real and fpc_round_real, strictly they are not necessary after the above change to code generation, but it still reduces size of system unit by avoiding compilation of related generic code.

3c3ad705f1 * changed fpc_(u)char_to_shortstr() from a procedure into a function, like
the other fpc_(u)char_to_*str() routines (exception dates back to the
    time calls to these routines were still inserted "manually" in the
    compiler). Fixes the compilation of "shortstr:=widecharconstant" after
    r23613 and simplifies other code calling this helper + test

a26bc50ca6 compiler: change ShortString->(Some)String and AnsiString->(Some)String overload precedence both for variables and string constants, change unicode constant type from widestring to unicodestring (Delphi compatibility)
new ShortString->(Some)String precedence: ShortString, UTF8String, AnsiString, AnsiString(CodePage) and RawByteString, UnicodeString, WideString and other string types
new AnsiString->(Some)String precedence: RawByteString, UTF8String, AnsiString, AnsiString(CodePage), UnicodeString, WideString, ShortString and other string types

The new logic makes UTF8String more preferrable than other AnsiString types, AnsiString more preferrable than other  AnsiStrings(codepage) and also makes UnicodeString more preferrable than WideString.

aee5380ae0 * merged trunk up to r20882
o support for the new codepage-aware ansistrings in the jvm branch
   o empty ansistrings are now always represented by a nil pointer rather than
     by an empty string, because an empty string also has a code page which
     can confuse code (although this will make ansistrings harder to use
     in Java code)
   o more string helpers code shared between the general and jvm rtl
   o support for indexbyte/word in the jvm rtl (warning: first parameter
     is an open array rather than an untyped parameter there, so
     indexchar(pcharvar^,10,0) will be equivalent to
     indexchar[pcharvar^],10,0) there, which is different from what is
     intended; changing it to an untyped parameter wouldn't help though)
   o default() support is not yet complete
   o calling fpcres is currently broken due to limitations in
     sysutils.executeprocess() regarding handling unix quoting and
     the compiler using the same command lines for scripts and directly
     calling external programs
   o compiling the Java compiler currently requires adding ALLOW_WARNINGS=1
     to the make command line

26f66897cd compiler:
- warn if compiler finds implicit or explicit string type conversion from a form of ansi string to a form of unicode string and vice versa
  - mark explicit warnings as OFF by default
  - warn if compiler finds an assignment of an unicode char const to ansi string or char type (warn for assignment of unicode string const to be implemented)
  - revert a piece of code from r19457 regards shortstring handling because shortstring handling should not differ from ansistring in this paticular case

c1866d5c17 compiler:
- don't pass CP_NONE encoding to internal functions. They handled it as 0 encoding. This will optimize the generated code a bit.
  - convert all king of string/char/pchar constants to local ansistring def if they needs to be passed to rawbytestring type. They should not get a CP_NONE codepage (delphi compatible)
  - don't convert left and right arguments of string concatenation to ansistring type if they are already ansistrings but with different codepage - RTL already handles different codepages in concat routine
  - fix resultdef for ansistring concatenations inside assignments - return def of left assignment operand if it is already ansistring - this reduces amount of unneeded condepage conversions since concat functions can return result in any desired codepage
rtl: remove CP_NONE comparisions from most of RTL functions, replace 0 constant with CP_ACP
tests: add test to check various conversions to RawByteString type

  - add helper function getansistringdef which return a def with explicitly set codepage or cansistringtype in other case
  - change tstoreddef.createnai constructor to allow set codepage in constructor
  - don't convert string constants to rawbytestring. if string constant already has a codepage - preserve it or convert to ansistring codepage (delphi compatible)
  - don't perform string conversion from ansistring to strings with explicitly set codepage (by directive or by compiler switch) and vice versa (delphi compatible)

defcmp: Address code paged' string type comparison taking care of the code page
  ncnv: Remove un-needed code page comparison to CP_UTF8, some fixes regarding shortstrings and wide char/string 
  ncon: For the case of tstringconstnode.changestringtype (ncon.pas) where the code page are of CP_NONE or 0 no translation is done as :
    * CP_NONE is compatible to all
    * For 0 the raw bytes are just copied.
 My changes:
  - change ascii2unicode to allow pass source codepage, 
  - convert in both cases when source or destination is UTF8
