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"

9d48bc0baf Implement cross unit type overloading of generics. This fixes the regression introduced with revision 25498.
symtable.pas:
  + add new tsymbol_search_flag type which can be passed to various searchsym* routines
  + add support to not call "addsymref"
  + add new searchsym_with_flags function that calls searchsym_maybe_with_symoption
  * adjust searchsym_maybe_with_symoption, searchsym_in_class & searchsym_in_helper to use new flag type instead of Boolean arguments
  * adjust searchsym & searchsym_with_symoption which call the modified functions
nutils.pas, handle_staticfield_access:

pexpr.pas, handle_factor_typenode, postfixoperators, factor:

scanner.pas, try_consume_nestedsym:
  * adjust searchsym_in_class call
fmodule.pas, tmodule:
  + add genericdummysyms field which is a TFPHashObjectList that contains TFPObjectList instances per generic dummy that in turn contains tgenericdummysyms instances
pgenutil.pas:
  + add function split_generic_name to split a generic name into non-generic name and count value of type parameters
  + add function resolve_generic_dummysym which tries to use the new genericdummysyms field to find the real symbol of a dummy sym
  * generate_specialization: adjust searchsym_in_class call
  * specialization_init/specialization_done: save/restore genericdummysyms of module
symdef.pas, tdefawaresymtablestack:
  + add new intermediate method pushcommon which is used by both push and pushafter
  + add new intermediate method remove_helpers_and_generics (which calls remove_generics and remove_helpers if necessary)
  * rename removehelpers to remove_helpers
  * rename addhelpers to add_helpers_and_generics and extend it to correctly fill current_module.genericdummysyms
  * call remove_helpers_and_generics from pop instead of remove_helpers
ptype.pas, single_type, read_named_type.expr_type, read_named_type:
  * try to resolve symbols with sp_generic_dummy with resolve_generic_dummysym

f1f89c77c3 Finally refactor "b_needs_init_final" flag to be a symtable flag which is written to/loaded from the PPU (as discussed in the thread "Status report for "class helpers"" in fpc-devel on 29th January 2011).
symconst.pas:
    + add "sto_needs_init_final" value to "tsymtableoptions"
symtable.pas:
    - TStoredSymtable: remove "b_needs_init_final"
    + TStoredSymtable: add "init_final_check_done" (which is False by default)
    * TStoredSymtable.ppuload: set "init_final_check_done" to True if PPU is loaded (because the flag will then already be restored)
    * TStoredSymtable.needs_init_final: check the symbols only if "init_final_check_done" is not set yet
    * TStoredSymtable._needs_init_final: only check the symbol if "sto_needs_init_final" is not set yet and set the flag accordingly if needed
utils/ppuutils/ppudump.pp:
    * respect the new flag

70886d1727 Fix the exception reported in Mantis #24072. This does not mean though that the bug is fixed, because the bug itself is related to the topic "partial specialization".

a972de5a32 * renamed the first parameter of is_owned_by() from "childdef" into
"nesteddef", because it's about def's owned by other defs, not about
    parent/child relations like in OOP
  * stop checking whether a def is owned by another one when we reach a
    para/localsymtable, since a type declared locally in a record/object
    method is not nested inside the record/object type (fixes mantis
    #23819)

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

3798b79fd7 + optimization that (re)orders instance fields of Delphi-style classes in
order to minimise memory losses due to alignment padding. Not yet enabled
    by default at any optimization level, but can be (de)activated separately
    via -Oo(no)orderfields
   o added separate tdef.structalignment method that returns the alignment
     of a type when it appears in a record/object/class (factors out
     AIX-specific double alignment in structs)
   o changed the handling of the offset of a delegate interface
     implemented via a field, by taking the field offset on demand
     rather than at declaration time (because the ordering optimization
     causes the offsets of fields to be unknown until the entire
     declaration has been parsed)

dbc410de63 Allow the usage of a generic's name without type arguments inside of nested classes inside the generic. This fixes Mantis #19499, but also Mantis #18688.
* symtable.pas:
    + add function "get_generic_in_hierarchy_by_name" which returns a def with the name of the symbol in the given object/record hierarchy (useful only in non-Delphi modes)
    + add function "return_specialization_of_generic" which returns the specialization def of a given class inside the given object/record hierarchy
* pexpr.pas, factor, factor_read_id: instead of checking whether the names of the found symbol and the current_structdef are equal, check whether the generic appears in hierarchy of current_structdef
* ptype.pas:
    * id_type: check whether the found symbol is a generic dummy and we are currently parsing a generic then return the correct def of the generic instead of the dummy one
    * single_type: when using the generic type without type parameters the def must resolve to the specialized def when specializing the class instead of the generic def which the dummy symbol points to
    * read_named_type, expr_type: like in "single_type" we need to resolve the use of the parameterless type name to the correct specialization def instead of the generic def
* pdecobj.pas, object_dec: also set the typesym of the current_structdef as otherwise some assumptions about generics with the above mentioned changes aren't valid anymore (like the def the typesym is unset again afterwards)
+ add tests for both bug reports (the one for 19499 is slightly modified so that it does not contain any errors)

810bd7ddab + symtable.pas, tspecializesymtable.create: SymList and DefList do not need to own the symbols and defs as they are moved to another symtable before the specialize symtable is destroyed (avoids the need to call "extract" on those lists)
* pgenutil.pas, generate_specialization: Correctly change the ownership of extracted symbols and defs by calling ChangeOwner on the symbol/def which does all the magic of changing the owner and adding it to the corresponding list of the given symtable. This fixes Mantis #21550
* Adjusted tw21550.pp so that it enforces the generation of debug information which (as this was the option which caused the above mentioned bug to show)

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

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 "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).

    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.

b8589d98cc compiler: Don't allow duplicate property/procedure identifiers inside object declaration. The code which allowed this for delphi mode was initially written based on invalid test from mantis #0009176. Fixes bug #0020580.

a133a6af3f Fix compilation of unit "fgl.pp" and of test "tests/test/tgeneric29.pp".
symtable.pas:
  * reduce the "childdef" parameter of "is_owned_by" from "tabstractrecorddef" to "tdef", so that more primitive defs can be checked as well
  * add a new function "sym_is_owned_by" which is similar to "is_owned_by", but takes a symbol and a symtable as parameter; the owner chain of the symtable is checked until a non-object- and non-record-symtable is reached

ptype.pas:
  * extend "id_type", so that the symbol and the symtable that belongs to the returned def is returned as well
  * this is needed to check inside "single_type" whether a def that is a generic was specialized inside another generic, because in that case the genericdef is returned by "generate_specialization" and not a new specialized def, but the corresponding type symbol (which is different from "hdef.typesym") belongs to the class itself; I need to admit that this solution isn't very clean and one could try to circumvent some of the checks, so I need to find a better detection for such a case (concrete example: the enumerator specialization inside the classes of "fgl.pas")
  * in "read_named_type.expr_type" the check for "df_generic" is extended analogous to the previous change, but instead of relying on the symbol it uses the def. This is needed so that types like method pointers that are defined inside the current generic are not disallowed as they contain the "df_generic" flag as well; like the previous change this change isn't clean either and maybe it's better to remove the inclusion of the "df_generic" flag from everything except records and "objects" inside records/"objects" again. Such a solution will "only" reduce the problem to records and "objects" though...

pgenutil.pas:
  * only add a new undefined def if we're not parsing the parent class or interfaces ("parse_class_parent" is true), otherwise the InternalError regarding the "equal count of defs" will trigger
  * there are now two cases where we need to return a generic def instead of a undefined one when we're parsing a generic:
    a) we have the previously mentioned case that "parse_class_parent" is true
    b) an undefined def was added, but we need to return a generic def, so that checks can be passed
  * use the correct variable when building the generic name, otherwise we get errors like "identifier '$1' not found"
  * don't push the symtable if we're currently parsing the list of interfaces or the parent class, because then e.g. a generic interface will be included in the symtable of the implementing class which isn't what we want; the current solution is not clean though, so this needs to be investigated more
  * Note: In the current state of "generate_specialization" the function could be simplyfied a bit more; this will be done when the implementation is satisfactory enough

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"

40e0b4677a + support for (only named, for now) records in the JVM target:
implemented via classes, all descending from system.FpcBaseRecordType
    (records are also considered to be "related" to system.FpcBaseRecordType
     on the JVM target)
  * several routines are auto-generated for all record-classes: apart
    from a default constructor (if there is none), also clone (which
    returns a new instance containing a deep copy of the current
    instance) and deepCopy (which copies all fields of one instance
    into another one)
   o added new field "synthetickind" to tprocdef that indicates what
     kind of synthetically generated method it is (if any), and
     mark such methods also as "synthetic" in the JVM assembler code
   o split off the JVM-specific parser code (e.g., to add default
     constructors) into pjvm.pas
