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

1ac4021178 * moved po_has_inlininginfo from procoptions to procimploptions so that
the availability of the body of a function declared as "inline" no
    longer changes the CRC and hence no longer triggers recompilations

52af9a2c89 * Changed passing of hidden parameters to constructors of class-style objects: VMT is always passed in the first ('self') parameter, and the second one ('vmt', although this name is now misleading) contains flag specifying the constructor behavior and meaning of 'self'. Together with r26656 this removes methodpointer sharing between two parameter node trees, it becomes possible not to put methodpointer into temp, but use node tree below 'self' parameter to do virtual calls. This also matches behavior of Delphi.

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,...)"

344571cb4e Added support for type helpers. In non Delphi modes they use "type helper" and in mode Delphi they use "record helper". They can also be used on constants.
symconst.pas:
  + extend "thelpertype" by "ht_type" which tells the code in "pdecobj.parse_extended_type" that a type helper declaration has been parsed
node.pas:
  + add a constant which identifies all constant node types
ptype.pas:
  + read_named_type: add a parameter "hadtypetoken" to tell the code whether a "type" token had been parsed before
  + read_named_type: if an identifier "helper" is parsed we need to check whether "hadtypetoken" is true and the modeswitch "m_class" is set, but the "m_delphi" one is not; in that case we have a "type helper" declaration
pgenutil.pas, generate_specialization:
  * adjust call to read_named_type
pdecl.pas, types_dec:
  * adjust call to read_named_type

pdecobj.pas:
  * parse_extended_type: extend for correct handling of primitive types (includes Delphi compatible handling as well) and reject types that are explicitly not allowed
  * method_dec: require "static" for class methods in type helpers
  * method_doc: allow constructors for type helpers as well
paramgr.pas, tparamanager:
  * set_common_funcretloc_info: handle type helper constructors like record constructors
  * handle_common_ret_in_param: the "self" value of a type helper constructor is also returned in a parameter
pexpr.pas:
  + add a function to postfixoperators which tries to find and apply a type helper for a given type
  * postfixoperators: try to apply type helpers for ordinal constants
  * postfixoperators: use the correct string type for string constants
  * postfixoperators: try to apply type helpers for enum constants
  * postfixoperators: try to apply type helpers for arrays
  * postfixoperators: try to apply type helpers for Variant
  * postfixoperators: try to apply type helpers for pointer types
  * postfixoperators: try to apply type helpers for other types
  * factor: check postfixoperators after _REALNUMBER, _CCHAR, _CWCHAR, _TRUE and _FALSE
  * factor: also check postfixoperators if a _POINT follows a _NIL

symdef.pas, tdefawaresymtablestack.addhelpers:
  * use "generate_objectpascal_helper_key" to generate the key
symtable.pas:
  + add function to generate the key value for the map of extended types using the extended def
  * adjust "search_last_objectpascal_helper" and "search_objectpascal_helper" to handle primitive types as well
  * use the new "generate_objectpascal_helper_key" function to generate the key

pparautl.pas:
  * insert_self_and_vmt_para: don't insert the $vmt symbol for record or type helpers (ToDo: check whether class helpers really need the symbol as well)
  * insert_self_and_vmt_para: pass "self" as var parameter for type helpers as well
psub.pas, generate_bodyentry_block: 
  * also allow type helpers for constructor methods
ncal.pas, tcallnode.gen_self_tree:
  * also use a temp variable for type helper constructors
ncgcal.pas, tcgcallnode.secondcallparan:
  * allow Pointers to be passed as address param if it is the Self value of a type helper extending a pointer type
  * correctly handle the location in case of type helper constructors

+ add tests

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

0d5b2b84a8 + Android/JVM target, including a translation of the Android r14 SDK
(= Android 4.0) java headers: java.*, javax.*, org.*, junit.*, android.*).
    The RTL can also be used to target earlier versions of the Android
    platform, but you manually have to take care of not using APIs that
    weren't available yet. Adding separate units for separate platform
    versions would only partly solve the problem, because some of the
    classes used inside the system unit have also changed across
    versions.

    Use -Tandroid while compiling to select the Android OS as target
    platform.

6a7ff1cf75 * use temp-reference nodes rather than addrnodes to create references to
complex parameters passed to inlined routines on the JVM target, because
    it is not possible to take the address of any kind of node on the JVM
    target (temp-reference nodes work for any kind of LOC_(C)REFERENCE, but
    are currently only implemented for the JVM platform)

d6966e545b + support for formal var/out parameters on the JVM target:
o primitive types are first boxed
   o the parameter is passed inside an array of one class instance
   o changing the parameter inside the routine (by assigning a value to it
     like in Delphi.NET and different from regular Pascal code) will replace
     this class instance (again boxing the value if required)
   o on return, the class instance is extracted, unboxed if required, and
     assigned back to the original location
   o formal const parameters are handled without the extra array indirection,
     since they cannot be changed

  TODO: while writing tjvmcallparanode.handleformalcopyoutpara() I forgot that
    calling getcopy on ttemprefnodes whose ttempcreatenode hasn't been copied
    yet works fine, so that code is more complex than needed. Still have to
    fix.

96b0ee0827 * added more options to format the result of tprocdef.fullprocname() via
a new customprocname() method and tprocnameoption flags (add parameter
    names, add "function"/"procedure", add name of owning struct or not,
    don't add the "class" prefix for class methods)
   Reason: for internal use by the compiler so it can output the procdef
    into something that can be fed back to the parser for reuse (seems
    easier than manually constructing a new procdef, or duplicating it
    inside of another objectdef)

   o because of the previous point, make sure that we handle the
     "function result" properly and don't pop too many values from
     the evaluation stack when calling one constructor from another
   o added "extra_pre_call_code" method used by njvmcal to insert
     the "new" opcode to create the new class instance before
     calling a constructor
   o when a constructor does not call any other constructor (inherited
     or otherwise), automatically insert a call to the inherited

  * order parameters for jvm similar to those for i386 without fixed_stack,
    so we don't need temporary paralocations
  * converted most of ncgcal to thlcg
  * disabled special handling for virtual methods for jvm in ncgcal, as all
    invocations are name-based there
  + njvmcal with special jvm callnode support:
   o always move the function result into a memory temp
   o when freeing an unused function result, use a_pop(2) and adjust
     the internal evaluation stack height counter
   o after the call instruction, adjust the evaluation stack height counter
     by subtracting the number of the pushed parameter slots, adjusted for
     the slots taken up by the function result

0ee702b3a2 * tprocdef.mangledname now gets an extra boolean parameter indicating
whether the mangled name is for defining a symbol, or for referencing
    it later (e.g. for a call or load of its address). The reason is that
    on the JVM both cases are different.
  + jvmdef unit to encode types according to the JVM rules
  + tprocdef.jvmmangledname() to encode a procdef's JVM mangled name

24243f87e8 Added a check similar to the "allowed" one to be able to remove the "current_syssym" variable again.
* nld.pas:
- added "helperallowed" boolean field to ttypenode which is set to false by default
- check that field in ttypenode.pass_1 and generate an error if it's false
* ncal.pas:
check the "helperallowed" field if the methodpointer node is a typenode and contains a helper; this is needed, because pass_1 of ttypenode is never called in case of "TSomeHelper.SomeMethod"
* pexpr.pas: 
- allow helpers in "sizeof" and "typeinfo"
- remove the check against "TSomeHelper.SomeMethod", but leave an explaining comment there

963a4d7b23 Commit of a completely restructured helper implementation. Instead of changing objectdefs with odt_classhelper to odt_class, they'll have the odt_helper type assigned to and this will be kept. This also implies that the parent of a helper is its true parent while the extended type is set to a field in tobjectdef (extendeddef).
This change became necessary of the following reasons:
- Records don't support inheritance, thus for "record helpers" some creativity would have been necessary to implement them; with the new implementation this is more easily
- the new approach allows for easy checks regarding virtual methods and their overrides which would have been more complicated in the old variant
- if someone feels the need the types of helpers (object, interface) can be added rather easily
- unnecessary things like VMT generation can be disabled now

details:
- msg*: 
* moved some messages from parser to type
* adjusted a message ("class helper" => "helper")
- symdef.pas:
* renamed "helperparent" to "extendeddef" and changed its type from "tobjectdef" to "tabstractrecorddef", so records can be extended as well (somewhen in the near future)
* removed "finish_class_helper" method as it isn't necessary (luckily I haven't yet adjusted the ObjC variant)
* changed name of "is_objectpascal_classhelper" to "is_objectpascal_helper" to reflect that this function applies to all helper types
* tobjectdef.create: ImplementedInterfaces isn't created for odt_helper anymore
* tobjectdef.alignment: for helpers it's the same as for classes although this shouldn't be used anywhere...
* tobjectdef.vmtmethodoffset: set to 0 for helpers to be sure...
* tobjectdef.needs_inittable: not needed for helpers (no fields allowed)
* is_objectpascal_helper: only needs check for "odt_helper" object type
- symconst.pas:
* changed odt_classhelper to more general odt_helper
* added new type "thelpertype" which is used to check that "(record|class) helper" corresponds with the given extended type (as Delphi XE checks this as well this strict solution can be kept for modes Delphi and ObjFPC)
- symtable.pas:
* extended "searchsym_in_class" with the possibility to disable the search for helper methods (needed for inherited) => this implies changing all occurences of "searchsym_in_class" with a "true" except some special locations
* renamed "search_objectpascal_classhelper" to "search_objectpascal_helper"
* searchsym_in_class: 
** when an extended method is defined with "overload" it can be that a same named method of the extended class might be called (sadly this means that this search was unnecessary...)
** contextclassh is the def of the helper in the case of an inherited call inside the helper's implementation
** when methods inside a helper are searched, it must be searched in the extended type first
- ptype.pas:
* single_type is used to parse the parent of a helper as well, so allow a helper if the stoParseClassParent is given (needs check in pdecobj.pas/parse_class_parents for normal classes)
* read_named_type: currently the only case when something <> ht_none is passed to the modified parse_objdec (see below) is when the combination "class helper" is encountered ("record helper" will be another one)
- pinline.pas: adjustment for extended "searchsym_in_class"
- pexpr.pas:
* adjustments regarding "searchsym_in_class" and "is_objectpascal_helper"
* factor/factor_read_id: moved the check for "TSomeClassType.SomeMethod" outside of the "is_class" check
* factor: 
** in case of an inherited we need to search inside the extended type first (Note: this needs to be extended to find methods in the helper parent if no method is found in the extended type)
** we also need to disable the search for helper methods when searching for an inherited method (Note: it might be better to introduce a enum to decide whether a helper method should search before or after the methods of the extended type or even never)
- pdecsub.pas:
* insert_self_and_vmt_para: in a helper the type of Self is of the extended type
* pd_abstract, pd_final: more nice error message
* pd_override, pd_message, pd_reintroduce: adjusted checks because now "is_class" is no longer true for helpers
* proc_direcdata: allowed "abstract" for helpers (only to produce a more nice error message)
* parse_proc_direc: adjustment because of "is_objectpascal_helper"
- pdecobj.pas:
* adjustments regarding "is_objectpascal_helper"
* adjusted object_dec to take the type of the helper (class, record) as a parameter to be able to check whether the correct extended type was given
* struct_property_dec: properties are allowed in helpers
* parse_object_options: nothing to be parsed for helpers (at least I hope so ^^)
* parse_parent_classes: 
** the parent of a helper is now parsed as a normal parent, the extended type is parsed in an extra procedure
** check for "sealed" no longer needed
** added check that the parsed parent of a helper is indeed a helper
** allow to parse the closing ")" of the helper's parent
* parse_extended_class:
** new procedure that parses the type which is extended
** it checks that the extended type is a class for "class helper" and a record for "record helper"
** it checks that a helper extends the same class or a subclass for class helpers
** it checks that a helper extends the same record for record helpers
* parse_object_members:
** "type", "const", "var" is allowed in helpers
** don't exclude flags regarding virtual methods, they are needed for the checks in mode Delphi (this implies that VMT loading must be disabled for helpers)
* object_dec:
** don't change "odt_helper" to "odt_class", but still include the "oo_is_classhelper" flag
** allow the parsing of object options (there are none)
** parse the extended type for helpers
- pdecl.pas
* adjustment because of extension of object_dec
* types_dec: remove the call to finish_classhelper
- objcdef.pas
* objcaddencodedtype, objcdochecktype: add references to helpers as implicit pointers although that should not be used in any way...
- nld.pas
* tloadnode.pass_typecheck: self is a reference to the extended type
- nflw.pas
* create_for_in_loop: adjustment because of changed procedure and inheritance type
- ncgrtti.pas
* TRTTIWriter.write_rtti_data: disable for helpers for now (I need to check what Delphi does here)
- ncgld.pas
* tcgloadnode.pass_generate_code: virtual methods of helpers are treated as normal methods
- ncgcal.pas
* tcgcallnode.pass_generate_code: virtual methods of helpers are treated as normal methods
- ncal.pas
* tcallnode.pass_typecheck: adjust for extension of tcallcandidates constructor
- htypechk.pas
* tcallcandidates declaration: extend some methods to (dis)allow the search for helper methods (needed for inherited)
* tcallcandidates.collect_overloads_in_struct: 
** search first in helpers for methods and stop if none carries the "overload" flag
** move the addition of the procsyms to an extra nested procedure because it's used for helper methods and normal struct methods

4aeef5b150 Fixes to dispatch calls:
* Pass dispinterfaces with correct type (varDispatch).
* Pass skipped parameters as EmptyParam (vType=varError, vError=DISP_E_PARAMNOTFOUND), as COM requires to preserve correct argument count and positions.
* Since ttempcreatenode.size can be set after creation, don't calculate parameter size in first pass, this simplifies things a bit.

* Create implicit access methods, which hold type information for property parameters and allow parsing/typechecking occur the same way as for regular (non-dispinterface) properties.
+ Introduce separate proctypeoptions for property access methods. They are translated into correct dispatch call types and used to distinguish property access from regular method calls.
* Bump PPU version because new information has been introduced.
- Code specific to dispinterface properties in expression parser is no longer necessary, removed.
* Allow access to default property with [] for dispinterfaces.
+ Extended the test with basic correctness checks for property dispatching.
