87d9714221 Somehow the changes regarding tf_methods_specialized weren't commited, thus here they are again:
* symconst.pas: remove tf_methods_specialized
* psub.pas: remove check for/inclusion of tf_methods_specialized as this isn't needed anymore since the generic is specialized in a temporary symtable

pgenutil.pas: remove merge artifacts

pdecl.pas: fix compilation ("s" was duplicate)

pexpr.pas:
* fix calling of generate_specialization
* disable the goto in sub_expr for now; this will be enabled again once right hand sides work as well

461d231daa Rebase to revision 19078 (directly before the merge of cpstrnew)
The changes regarding pretty names for generics and token buffer endianess were integrated into my changes. Not every call to generate_specialization is fixed though, so compilation will fail.

commit 7ef252de8023494ee6d39910e289f9e31658d47b
Author: Sven Barth <pascaldragon@minerva>
Date:   Mon Nov 21 17:13:36 2011 +0100

    Fix the compilation of inline specializations of which the generic is derived from another generic.
    
    pgenutil.pas, generate_specialization:
    * Set the "block_type" to "bt_type" when parsing the type parameters, so that the nodes are returned as "ttypenode" instead of e.g. "tloadvmtaddrnode" in case of classes outside of type sections.
    * Set the "block_type" to "bt_type" before calling "read_name_type", so that no unexpected sideeffects happen, because types like classes normally only are declared inside type sections (e.g. for the case a generic class is derived from another generic class a classrefdef for the specialized parent class will be created inside the derived specialized class if the block type is not a type one).

commit 1041a8f7a3a41f4fdf2975ce40055c698281ce71
Author: Sven Barth <pascaldragon@minerva>
Date:   Fri Nov 18 19:03:50 2011 +0100

    Improve inline specializations a bit, so now expressions like "TSomeGeneric<TSomeType>.SomeClassProc OP SomeNonGeneric" is possible. Using another class function of a generic as the right side is not yet working (that still needs some thinking).
    
    To achive this the generalization code must basically continue directly after the "factor" call, so that the operator and the right side are correctly parsed when walking up the call stack. This is done by jumping from the end of the specialization code in the "<"-case to the start of "sub_expr". The freshly generated node (in the above example a callnode) will be passed down the callstack through a new parameter "factornode". If that is set (currently only in the case of a specialization on the left side) "factor" won't be called and the right side will be parsed with the "factornode" as the left side. If it is not set (which is the case for all other calls to "sub_expr" in the unit) then the usual call to "factor" will be done and the result will be used as the left side.

    Fix compilation of ppudump.
    
    symconst.pas:
    * Remove sto_has_generic, which was the last remainer of my "overloaded type symbols" approach.
    * Remove df_methods_specialized, as it isn't needed anymore with the recent "temporary symtable" solution.
    
    psub.pas, specialize_objectdefs, process_abstractrecorddef:
    Remove the checks for/inclusion of df_methods_specialized.
    
    utils/ppudump.pp:
    Add "sp_generic_dummy" to the symbol options.

commit d16deac060e65d4b53e8fe9c27fe7e1f6d00a416
Author: Sven Barth <pascaldragon@minerva>
Date:   Wed Nov 16 16:34:51 2011 +0100

    Fix compilation of "gset.pp" from fcl-stl.
    
    nld.pas:
    Extend ttypenode by a reference to the type symbol. Normally this is simply the typesym of the given def, but for specializations in type sections of generics this is not the case, because generate_specialization will return a reference to the generic definition and not the new one (thus the symbol will be wrong).
    
    ppu.pas:
    Increase PPU version because of the extension of ttypenode.
    
    pexpr.pas:
    * handle_factor_typenode: Extend the function by a "sym" parameter which will normally be "nil". In that case it is set to the def's typesym. The "typesym" field of the created type node is then set to this sym.
    * For now pass nearly always "nil" for the above mentioned sym except inside factor_read_id when we've encountered a typesym.
    
    ptype.pas, read_named_type, expr_type:
    Exchange the "is_owned_by" check with a "sym_is_owned_by" check so that we can correctly detect that we are using a specialized type declaration inside a generic (once nested generic are allowed this condition needs to be checked).

    psub.pas:
    * tcgprocinfo.parse_body: Methods of generic classes need to set "parse_generic" as well, so that variables for "stacked generics" (generic array => generic record) inside the method body are handled correctly.
    * specialize_objectdefs: Don't try to generate method bodies for abstract methods.
    
    pdecvar.pas, read_property_dec:
    Allow specializations for the return types of properties (should they be allowed for index types as well?).
    
    symtable.pas:
    Add a new class "tspecializesymtable" which is basically a globalsymtable but is always assuming to be the current unit. This symtable is used in "generate_specializations" (see below) and is needed to allow visibilty checks for "private", etc. to succeed.
    
    pgenutil.pas, generate_specializations:
    Instead of hackily pushing a symtable that may contain conflicting symbols onto the symtable stack for the specialization, a temporary global symtable using the above mentioned "tspecializesymtable" is created and pushed. After the specialization is done all symbols and defs that were added to the temporary symtable are moved to their final symtable (either the global- or localsymtable of the unit, depending on the current position of compilation). This way symbols are correctly added to a top level symtable, but without potential side effects like resolving the wrong symbol.

  - write overriddenpropsymderef only in case if property has ppo_overrides flag
  - save/load parameters symtable only in case if property has ppo_parameters flag and has not ppo_overrides flag
  - in case if property is overrides and has parameters copy original symtable

feeff56099 We need to flag specializations of record-/objectdef once we have generated their methods otherwise an interesting situation might occur:
The classes in "fgl.pas" implement an enumerator in the generic class "TFPGListEnumerator" and "specialize" that inside themselves. If we now specialize one of the generic classes (e.g. "TFPGList") the "TFPGListEnumerator" is really specialized as well. That means a def is added to the global symtable (the local one in case of a program or library file). If we now use the enumerator class in the same file (e.g. by using a "for ... in", which has a temporary variable of that type) then the methods of the enumerator are specialized again (the def itself is not). To avoid this (and time consuming searches for existing method specializations) we flag the specialized def as "done" once we're finished.

symconst.pas
  * add a new flag "df_methods_specialized" to the "tdefoption" enumeration

psub.pas, process_abstractrecorddef
  * check the def for the "df_methods_specialized" flag and continue only if that is not set
  * set the "df_methods_specialized" flag before leaving the function

90278ec755 Allow generics to be overloaded by variables.
* symconst.pas:
   add an entry for the generic dummy symbol to the symbol options enumeration
* pgenutil.pas:
   - extend "generate_specialization" by the possibility to pass a symbol name instead of a def
   - if "symname" is given that is used; otherwise "genericdef" or "tt" is used
* pexpr.pas:
   - in case of "<" we are trying to receive a generic dummy symbol from the left node (new function "getgenericsym")
   - it's name is then passed to "generate_specialization" which in turn fills genericdef
   - adjust call to "generate_specialization"
* pdecl.pas:
   - we can now check for "sp_generic_dummy instead of "not sp_generic_para" to check whether we've found the dummy symbol of a previous generic declaration
   - if a new dummy symbol is created we need to include "sp_generic_dummy"
   - if we've found a non-generic symbol with the same name we need to include the "sp_generic_dummy" flag as well
* symtable.pas
   - add a new function "searchsym_with_symoption" that more or less works the same as "searchsym", but only returns successfully if the found symbol contains the given flag
   - "searchsym_with_symoption" and "searchsym" are based on the same function "maybe_searchsym_with_symoption" which is the extended implementation of "searchsym" (note: object symtables are not yet searched if a symoption is to be looked for)
   - add a function "handle_generic_dummysym" which can be used to hide the undefineddef symbol in a symtable
   - correctly handle generic dummy symbols in case of variables in "tstaticsymtable.checkduplicate"

005795495d merge r17552 from cpstrnew branch by inoussa:
*In normal procedure "var" and "out" RawByteString parameters does not accept other string types. Procedures with
"compilerproc" directive or the newly added "rtlproc" directive accept that. Please note that it is up to the
procedure coder to ensure the correctness of the code page in that case. The new directive is needed to handle 
the RTL procedures/functions that are not marked as "compilerproc" such as "UniqueString", "Insert" and "Delete".

*Correct "fpc_ansistr_concat" to handle code page correctly.

*Default "ansitring" type is now created with code page set to "0" instead of "65535". Before that change it was 
impossible to distinguish a "RawByteString" with the default "ansistring". At runtime "ansistring" variable'code
page is set to DefaultSystemCodePage

*UniqueString flavor of "SetLength" has been updated to release memory when shrinked to at least 50%, like ansitring
does.

80100734c5 *type symbol overloads are only allowed in mode Delphi
*a check for overloads with the same count of arguments is not yet in place
*in non-Delphi modes overloads need to be checked for non-generics as well, e.g. "TTest<T>" is already defined and now a "TTest" is declared
*when a generic is encountered and the symbol does not yet exist, a new symbol with an undefineddef is added and the generic def is added as an overload; if the symbol already exists, the generic is just added
*if a non-generic is parsed and the symbol is already defined (but the typedef is still an undefineddef) then the typedef is updated
*the symtable tree (up to the unit symtable (global or local)) gets the "sto_has_generic" flag which will be used when searching generics with the same name, but different parameter counts in different units

State of generics:
broken, because the generic defs are not yet searched/found

b0b051ae83 Introduce a new type kind for helpers in the RTTI. This is Delphi incompatible, but it's cleaner than Delphi's "let's extend some magic class". This might not matter much though, because according to Google the RTTI for class helpers seems to be rarely used.
* compiler/ncgrtti.pas:
- objectdef_rtti_class_full:
 - don't write the VMT data for helpers
 - write the typeinfo of the extended type (something that Delphi does definitely not support :P )
- objectdef_rtti: write the new type kind for helpers instead that of classes
* compiler/symconst.pas: introduce new type kind constant "tkHelper" before "tkFile" (what is that used for btw?)
* rtl/inc/system.inc: add the constant here as well (why wasn't tkUChar added here?)
* objpas/typinfo.pp: 
- add tkHelper to the TTypeKind enum (but here tkUChar was added?!)
- extend the TTypeData record with the data of helpers

- tmodule.destroy: free the hash list
* pdecobjpas:

878c8c7806 Implemented correct handling of inherited methods.
- symtable.pas:
* I extended "searchsym_in_class" with a parameter to decide whether helpers should be searched before the normal class' methods, after them or not at all (as I'm not using that anymore, I might revert this to a simple Boolean again)
* Added a new function "searchsym_in_helper" which implements the algorithm to search for a symbol inside a helper's implementation. For more information on this algorithm please read the comment at the top of that function ("searchsym_in_class" also calls this function in the case that "classh" is a helper)
- pexpr.pas:
* fixes for extended "searchsym_in_class"
* in case of "inherited" and a helper the new "searchsym_in_helper" is called with the "hasinherited" parameter set to true
- pinline.pas:
fixes for extended "searchsym_in_class"
- symconst.pas:
added new enumeration for helper search order (might be removed again)

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

e19bcfae38 Added a flag set to TSymtable that tells whether it contains a class helper symbol, which is currently only used for static- and globalsymtables.
symconst.pas: added new enum tsymtableoption with set tsymtableoptions; currently it contains only sto_has_classhelper, but refactoring tstoredsymtable.b_needs_init_final is on the todo list
ppu.pas: added a new entry type that will hold the symtable options (91)
symbase.pas: added a new field "tableoptions" to TSymtable which will hold the flags of the symtable (only saved by tstoredsymtable)
symdef.pas: when a tobjectdef is created as a odt_classhelper or odt_objccategory the flag sto_has_classhelper is added to its owning global- or staticsymtable
symtable.pas: 
* load and write the symtable's options as a small set to an entry before the definition entries
* tabstractlocalsymtable needed to annoy me by not calling "inherited writeppu" which does the same as tabstractsymtable did before
* search_last_objectpascal_classhelper: check whether the static- or globalsymtable contains a class helper at all; if not then just continue with the next
utils/ppudump.pas:
* added reading of symtableoptions entry (as readsymtableoptions) based on the reading of tsym options
* added the reading of symtableoptions before every read of the contents of a TSymtable (definitions, symbols)

58f37dc952 Improvements to dispinterface property handling:
* 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.

aed9f0a5f7 Added first version of class helper support (not fully working and not fully featured)
- tokens: added support for "helper" token
- symconst.tobjecttyp: added a new entry "odt_classhelper"
- symdef: added two functions to check whether a "tdef" instance is a class helper in general ("is_classhelper") or an Object Pascal class helper in particular ("is_objectpascal_classhelper")
- symdef.tobjectdef: added a new method "finish_classhelper" which calls "create_class_helper_for_procdef" for every method (maybe this can be used for Objective-C categories as well)
- symdef.tobjectdef.create: "ImplementedInterfaces" must be created for class helpers as well
- symtable.searchsym_in_class: class helper methods must be searched for Object Pascal classes as well (this is currently wrong, as those must be searched before the class symbols, but for a first test it's sufficient)
- ptype.read_named_type: "helper for" currently indicates a class helper ("for" should be checked inside "object_dec" though, as after "helper" there might be a parent class helper)
- pdecobj.parse_parent_classes: parse the name of the extended class and disable sealed check for those
- pdecobj.object_dec: "odt_classhelper" are changed to "odt_class" and "oo_is_classhelper" is added to the object options
- pdecl.types_dec: create class helper symbols by using "finish_classhelper"

55a0fefb1f compiler: implement generic array type:
- add tarraysymtable to store generic type symbols
  - process generic and specialize declarations similar to generic records and classes
  - fix insert_generic_parameter_types to use def passed in argument instead of current_structdef because generic array type can't be assigned to the current_structdef variable
  - increase ppu version because of arraydef changes

210e78e4fa compiler: allow objects and records to have members which point to themself. only don't permit this to regular fields.
- remove testcurobject hack and perform a check only for regular fields
  - move is_holded_by to interface and rename it to is_owned_by
  - don't check static symbols in _needs_init_final because they always point to symbols registered on unit level
  - don't check object type in id_type, read_named_type when we are looking for type of structure member - the only check will be performed for record/object fields now

f13f6627c4 * moved use_fixed_stack from cgutils to a method in paramgr so it can
be used outside the code generator
  * renamed tabstractprocdef.requiredargarea into callerargareasize,
    and also added calleeargareasize field; added init_paraloc_info(side)
    method to init the parameter locations and init those size fields and
    replaced all "if not procdef.has_paraloc_info then ..." blocks with
    procdef.init_paraloc_info(callersize)"
  * moved detection of stack tainting parameters from psub to
    symdef/tabstractprocdef
  + added tcallparanode.contains_stack_tainting_call(), which detects
    whether a parameter contains a call that makes use of stack paramters
  * record for each parameter whether or not any following parameter
    contains a call with stack parameters; if not, in case the current
    parameter itself is a stack parameter immediately place it in its
    final location also for use_fixed_stack platforms rather than
    first putting it in a temporary location (part of mantis #17442)
  * on use_fixed_stack platforms, always first evaluate parameters
    containing a stack tainting call, since those force any preceding
    stack parameters of the current call to be stored in a temp location
    and copied to the final location afterwards

57bd6d2685 + merged nestedprocvars branch
+ support for nested procedural variables:
    o activate using {$modeswitch nestedprocvars} (compatible with all
      regular syntax modes, enabled by default for MacPas mode)
    o activating this mode switch changes the way the frame pointer is
      passed to nested routines into the same way that Delphi uses (always
      passed via the stack, and if necessary removed from the stack by
      the caller) -- Todo: possibly also allow using this parameter
      passing convention without enabling nested procvars, maybe even
      by default in Delphi mode, see mantis #9432
    o both global and nested routines can be passed to/assigned to a
      nested procvar (and called via them). Note that converting global
      *procvars* to nested procvars is intentionally not supported, so
      that this functionality can also be implemented via compile-time
      generated trampolines if necessary (e.g. for LLVM or CIL backends
      as long as they don't support the aforementioned parameter passing
      convention)
    o a nested procvar can both be declared using a Mac/ISO Pascal style
      "inline" type declaration as a parameter type, or as a stand-alone
      type (in the latter case, add "is nested" at the end in analogy to
      "of object" for method pointers -- note that using variables of
      such a type is dangerous, because if you call them once the enclosing
      stack frame no longer exists on the stack, the results are
      undefined; this is however allowed for Metaware Pascal compatibility)

rtl: add enumerators to the basic classes
tests: add enumerators test which compiles and work both by fpc and dcc
compiler: 
  + start for-in loop implementation: implement for-in loop for types (enumerations and ranges), strings, arrays and sets. todo: perform type checking, optimize array and string loops - use temp for expression, implement for-in loop for classes
test:
  + add a simple test for the 'for-in' loop
compiler: fix string for-in loop. now it uses a temp variable to store string expression result
complier: fix for-in array loop. use a temp variable for the loop expression only if loop is not an open array loop
complier: continue enumerator implementation:
  + add operator enumerator which give an ability to add enumerator for an existent type (for example to override builtin string enumerator)
  + add class enumerator support via delphi compatible GetEnumerator method + enumerator class/object template (function MoveNext: Boolean; property Current)
  + tests
compiler: fix for-in loop for arrays. delphi does not copy arrays to a temp variable and it is possible to change array during loop. + test
compiler: add reference for the enumerator operator when it is used + another test for operator enumerator for a class
compiler: add reference for the enumerator operator when it is used + another test for operator enumerator for a class
compiler: enumerator directive support:
  + allow to mark methods and properties by 'enumerator MoveNext' and 'enumerator Current' modifiers. Parser checks return types and duplicates.
  + prefer *marked* by enumerator directive methods and properties than GetEnumerator and Current builtin symbols
  + increase ppu version
  + test
rtl: add IEnumerator and IEnumerable interfaces declarations
tests: for-in loop tests:
  + add small comment at the top of test program
compiler: allow 'enumerator MoveNext' for the interface function declaration + test
compiler: move all for-in loop helpers to the nflw unit
