via {$modeswitch finalfields} (on by default on the JVM target). The
meaning is the same as in Java: a final (class) field can only be set
in a (class) constructor of the class it's defined in, and can only be
written once there (and *must* be set there). They are currently only
supported for external classes since that basically turns them into
constants, since for non-external classes we need full dataflow analysis
o refactored pdecobj.parse_object_members() a bit in the process to reduce
the amount of repetition (which would have been further increased for
the support for final fields)
o made error message about "wrong use of absolute" for fields etc generic,
so it gives a proper error depending on which token was used (it had
to be made generic for "final" support, but already was used for other
things that were wrongly reported as "absolute" misusages)
git-svn-id: branches/jvmbackend@18398 -
o support formal external definitions (like for objcclass)
o allow specifying an "import_dll" for external Java classes, which can
be used to specify the Java package name (like the dll for cppclass)
o take the package name into account when mangling the Java class name
o several messages that were specific to Objective-Pascal classes have
been generalised because they also apply to Java classes, same for
several compiler function names
o disabled some proccall directives for Java, but more needs to happen
(Java methods are always either instance-virtual or class-static)

* Factored repeating REX operations into a separate function.
* Fixed instruction matching bug which was preventing compilation of 3-operand SIMD instructions with RIP-relative operand + test.
* Do not adjust offset of RIP-relative reference if it is a literal number, this was causing 0x123(%rip) to assemble as 0x122(%rip) in 3-operand instructions. Now tasm2.pp is the same with and without -Aas. Also fixed the expected result, improved verbosity of diagnostic and removed %norun, so it is actually executed.

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

- pdecobj.pas: removed a check whether a class (helper) tries to inherit from a class helper, because now single_type handles this
- pexpr.pas:
* prohibit type casts to class helpers (note: this might be needed for ObjC categories as well)
* class helper references may only be used when inheriting from them (needs to be checked for ObjC categories as well)
- ptype.pas:
* single_type: extend check against categories for class helpers
* read_named_type: extend check against categories for class helpers
- symbase.pas: add a method that adds symbol table flags recursivly to a stack of symtables (it stops updating the symtables once a symtable already has that flag or it's a global-/staticsymtable)

* parse the "parent" of a class helper before parsing the extended class (the real parent)
* also disallow to inherit from class helpers for normal class (and to extend class helpers for class helpers)
* disallow the declarations of fields
* disallow the use of destructors
* don't parse abstract/sealed for class helpers
- compiler/ptyp.pas: _FOR is now parsed inside pdecobj.pas
- compiler/msg*:
* extended some messages for class helpers
* added some class helper related messages (perhaps the one or other will vanish again...)

- allow operator also if return type match the structure type (before at least one parameter had to match)
- search both operands symbol tables for a suitable assignment operator
- test
based on patch of Blaise Thorn (issue #0018490)
git-svn-id: trunk@16762 -
change is that it is now also allowed to specify an external name for
formal external class definitions, but if they are later mixed with
regular class definitions the external names have to match.
o because the "external" status of methods is now set while parsing the
class rather than afterwards, some procdir compatibility checks had to
be inlined because they only have to be performed for
* also adapted the syntax for external cppclasses in the same way
* fixed return type of NSObject.retainCount and NSObject.hash
(NSUInteger instead of cint)
* moved "patches" directory from cocoaint/src to cocoaint/utils/cocoa-skel
so they are used by the conversion script when re-parsing the headers
* updated Objective-C header parser script to
o use the new external class syntax
o not write inheritance information for root classes (NSObject, NSProxy)
o use internal translation tables for some conflicting method names that
are named specially in objcbase.pp
and updated parsed headers
* fixed rtl/inc/objcbase.pp and tests to conform to the new external class
syntax

------------------------------------------------------------------------
r16526 compiler: implement record methods and class methods:

- replace in many places use of current_objectdef to current_structdef with typcast where is needed
- add an argument to comp_expr, expr, factor, sub_expr to notify that we are searching type only symbol to solve the problem with records,objects,classes which contains fields with the same name as previosly declared type (like:
HWND = type Handle;
rec = record
hWnd: HWND;
end;)
- disable check in factor_read_id which was made for object that only static fields can be accessed as TObjectType.FieldName outside the object because it makes SizeOf(TObjectType.FieldName) imposible and since the same method was extended to handle records it also breaks a52 package compilation
