6cb6569d51 * Set pi_uses_exceptions flag when creating/firstpassing ttryexceptnode or ttryfinallynode, not when parsing try statements. It ensures that procedures with exception handling nodes created by compiler (constructors in the first place, but also for..in loops with TObject iterators, etc.) are handled the same way as ones containing exception nodes from user code.
* Modified code generation for constructors so they don't always use pi_needs_implicit_finally. It used to prevent stackframe optimization while not preventing regvar optimization ( tabstractvarsym.is_regvar() checks for pi_uses_exceptions but not for pi_needs_implicit_finally, and constructors were not getting pi_uses_exceptions), resulting in strange code using both exceptions and regvars.
Once setting of pi_uses_exception is fixed, the implicit finally frame can be omitted unless managed temps or local vars are actually present.

0a3a62811b + try/except and try/finally support for JVM target:
o always create exceptvarsym entry for on-nodes (on all targets) to remove
     some special cases when an unnamed exception was caught
   o the JVM tryfinally node generates the finally code twice: once for the
     case where no exception occurs, and once when it does occur. The reason
     is that the JVM's static bytecode verification otherwise cannot prove
     that we will only reraise the caught exception when we caught one in
     the first place (the old "jsr" opcode to de-duplicate finally code
     is no longer used in JDK 1.6 because it suffered from the same problem,

a944be69a6 * nflw.pas: search for enumerators in helpers for records as well
* pdecobj.pas:
- parse_object_members: in record helpers class methods need to be declared as "static" like in records
- object_dec: 
 - allow "published" in helpers as well
 - disallow inheritance for record helpers in mode Delphi (and remove the forward declaration flag in that case)
* pdecsub.pas:
pd_abstract: "abstract" isn't allowed in either mode
* pexpr.pas: multiple corrections because of "inherited" and records
- allow "inherited" for "record helpers" (except for mode Delphi)
- load the symbol from the correct class (I hope...)
- give a more precise error message if "inherited" is used in records
* ptype.pas: I forgot to adjust the "(bit)packed record" case
* symtable.pas:
- searchsym_in_helper: "result" was not initialized (and identation fix)
- search_last_objectpascal_helper:
 - don't search if there are no helpers (useful for projects that does not contain helpers like the compiler itself)
 - don't search if the type to search helpers for is defined locally
 - don't search if the type is a anonymous record
- search_struct_member: search for symbols in helpers as well
- msg*: 
* correct the message for "parser_e_not_allowed_in_helper"
* add message "parser_e_inherited_not_in_record" which is used to tell that the use of "inherited" is not allowed in records and (in mode Delphi) record helpers

f7f357f18e * symconst.pas:
- remove thelpersearch again => adjustments to searchsym_in_class and calls to it
- rename sto_has_classhelper to sto_has_helper
* symbase.pas: make push and pop in tsymtablestack virtual
* symdef.pas:
- add a new class tdefawaresymtablestack which overrides push and pop of tsymtablestack and adjusts the new extendeddefs field of the current tmodule
- tobjectdef.create: sto_has_classhelper => sto_has_helper
* fmodule.pas:
- add new hash object list to tmodule (key: mangled type name) which holds object list instances that contain all helpers currently active for a given type (= key of the hash list)
- tmodule.create: the hash list owns the sublists (but those don't own the defs)
- tmodule.destroy: free the hash list
* pdecobjpas:
- rename parse_extended_class to parse_extended_type
- parsing of constructors:
# for all helper types: no class constructors allowed
# for record helpers: as long as constructors for records themselves are disabled they are for record helpers as well
- object_dec: manually add the helper to the extendeddefs if the overall owner of the current def is a static symtable (implementation section or program/library main file), because the symtable won't be popped and pushed then
* parser.pas: instantiate the new stack class
* psub.pas: backup the extendeddefs in specialize_objectdefs as well
* ptype.pas:
- generate_specialization: backup the extendeddefs as well
- record_dec: _RECORD is now consumed in read_named_type itself
- read_named_type: parse "record helper" if advanced record syntax is enabled

- correct searchsym_in_class declaration => adjustments in this unit as well
- add the possibility to pass a context def to search_last_objectpascal_helper
- rename search_objectpascal_class_helper to search_objectpascal_helper
- rename search_class_helper to search_objc_helper
- searchsym_in_class: 
# search for helpers in every level of the tree of the class
# the contextclassh can also be a subclass of the extendeddef
- searchsym_in_record: search for helper methods as well
- searchsym_in_helper:
# search for symbols in class and record helpers is the same except for the search in the class' ancestors
# search the extendeddef directly and rely on searchsym_in_class only for the class' ancestors as we need to find the helpers there as well
- search_last_objectpascal_helper: use the extendeddefs list of current_module instead of scanning the symbol stack itself
* pexpr.pas: adjustments because of renaming of sto_has_classhelper
* pinline.pas: adjustment because of removing of thelpersearch
* nflw.pas: 
- renamed classhelper to helperdef
- adjusted search_last_objectpascal_helper call
* msg*:
- adjusted error message for constructors in records (this currently applies to record helpers as well)
- renamed parser_e_not_allowed_in_classhelper to parser_e_not_allowed_in_helper => adjustments in code
- added parser_e_no_class_constructors_in_helpers
* pdecsub.pas: adjusted renamed error message
* htypechk.pas: check for helpers in every step of the hierarchy
* nobj.pas: search_class_helper => search_objc_helper

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

a317827456 symtable.pas:
- moved "find_last_classhelper" out of "search_objectpascal_class_helper" so that it can be used in the "for ... in" code.
- renamed "find_last_classhelper" to "search_last_objectpascal_classhelper"
- fixed the unintentional use of a parameter ("srsymtable") of the parent function (it was intended as a variable from the beginning)
- "search_objectpascal_class_helper" now also checks whether the matched class helper method is visible; for this a new parameter for the contextclass was added which is passed when called from "searchsym_in_class"
nflw.pas: before checking for a "GetEnumerator" method in the class we now check whether one of the class helpers in the hierarchy that is available for that class (using "search_last_objectpascal_classhelper") implements such a method (I need yet to check whether Delphi supports the addition of "Current" and "MoveNext" as well)

56bf42de57 compiler: implement record methods and class methods:
- rename tprocdef._class to tprocdef.struct and change the type from tobjectdef to tabstractrecorddef because methods can belong not to classes only now but to records too
  - 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
  - rename tcallcandidates.collect_overloads_in_class to tcallcandidates.collect_overloads_in_struct and addapt the code to handle overloads in records too
  - fix searchsym_type to search also in object ancestors if we found an object symtable
  - add pd_record, pd_notrecord flags to mark procedure modifies which can or can't be used with records. Disallow the next modifiers for records: abstract, dynamic, export, external, far, far16, final, forward, internconst, internproc, interrupt, message, near, override, public, reintroduce, virtual, weakexternal,
Allow the next modifiers for records: static

  + 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

daniel
4b82d30953 * Removed sets from Tcallnode.det_resulttype
+ Added read/write notifications of variables. These will be usefull
   for providing information for several optimizations. For example
   the value of the loop variable of a for loop does matter is the
   variable is read after the for loop, but if it's no longer used
   or written, it doesn't matter and this can be used to optimize
   the loop code generation.

daniel
8cbd40c2f0 * The for node does a check if the first comparision can be skipped. I moved
the check from the second pass to the resulttype pass. The advantage is
  that the state tracker can now decide to skip the first comparision too.

399036f1c2 * State tracker work
* The whilen and repeatn are now completely unified into whilerepeatn. This
  allows the state tracker to change while nodes automatically into
  repeat nodes.
* Resulttypepass improvements to the notn. 'not not a' is optimized away and
  'not(a>b)' is optimized into 'a<=b'.
* Resulttypepass improvements to the whilerepeatn. 'while not a' is optimized
  by removing the notn and later switchting the true and falselabels. The
  same is done with 'repeat until not a'.
