as te_exact rather than as te_equal (otherwise you get compilation errors
if only a formal external definition is in scope in the interface, but
the full definition is in scope in the implementation)
git-svn-id: trunk@17201 -
* Moved nestedprocs from tcgprocinfo to tprocinfo, in order to be able to access the entire nested procedure hierarchy without depending on psub.pas or code generator.
* Creating an instance of tprocinfo automatically inserts it into list of parent's nested procedures.
* nestedprocs list is created on demand. Public read-only access is provided by has_nestedprocs and get_first_nestedproc functions.
+ Method destroy_tree is provided for destroying the entire hierarchy of procinfo's. It can be called on any procinfo object in the tree.
+ Also added methods save_jump_labels and restore_jump_labels for asmlabel maintenance, which is currently being repeatedly done all over the codegenerator.

+ parsing of section directive for variables
+ section test
+ write section names in the assembler/binary writers correctly
* allow section only after ; and for embedded targets

- 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
* symtable.pas:
- 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

# 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
* utils/ppudump.pas: adjust, because of renames
Note: the define "useoldsearch" will be only used for performance comparison on my (faster) Linux machine; that (and its associated code) will be removed afterwards
git-svn-id: branches/svenbarth/classhelpers@17151 -
* $CPU/cgcpu.pas: disable the generation of VMT loading code
* dbgstabs.pas, dbgdwarf.pas: treat virtual methods of helpers as normal methods
* ncgcal.pas: don't register virtual helper methods for WPO
* ncgrtti.pas: write virtual helper methods as normal methods to RTTI

git-svn-id: branches/svenbarth/classhelpers@17150 -
a temporary parameter location, since calls cannot overwrite parameters
already on the stack in that case (it will just grow)
git-svn-id: trunk@17144 -
* Now g_initialize, g_finalize, g_incrrefcount and g_decrrefcount should never more be used for open arrays, trigger internal error if it happens.
git-svn-id: trunk@17137 -
forward-declared class, only search the current symtable rather than the
entire symtable stack (to prevent finding types in e.g. nested types)
git-svn-id: trunk@17128 -
declared inside the the current structdef hierarchy: properly deal with
multiple types of the same name nested into each other, by keeping track
of at which point in the hierarchy we found the first type (and afterwards
continuing from there, instead of from any point in the hierarchy where
a type with this name can be found)
git-svn-id: trunk@17126 -
* Separated two almost identical parts of code into procedure rangecheck_string;
- Removed range checking of regular_array[constant], which should, according to the comments, happen in typecheckpass. tvecnode.pass_typecheck indeed does the necessary tests, so removing this duplicate check also eliminates duplicate warning when range checking is off.
git-svn-id: trunk@17124 -
enclosing types, so that it works both for single_type() and
read_named_type() (-> works inside class definitions)
* modified tclass13 to test this
git-svn-id: trunk@17111 -
* pdecl.pas: prohibit generic helper declarations
* pdecobj.pas: helpers extending generic types are not allowed (theoretically one could experiment with allowing this for Delphi style generics...)
* symtable.pas:
- is_visible_for_object: helpers can access (strict) protected fields of extended types
- searchsym_in_helper: use the correct contextclass and the correct search function
- search_default_property: search for default properties in helpers first
* symsym.pas: added a global variable that allows to track whether we are parsing inside a special system function
* pexpr.pas:
- statement_syssym: track the current syssym
- factor.factor_read_id: helper types are allowed inside "sizeof", "bitsizeof" and "typeinfo"
git-svn-id: branches/svenbarth/classhelpers@17097 -
* Unified fpc_initialize_array,fpc_finalize_array with fpc_decref_array and fpc_addref_array by removing 'size' parameter from the former two. Element size is easily calculated from RTTI, so omitting it simplifies code generation. All four helpers are now callable by tcg.g_array_rtti_helper().
* ncgutil.pas: initialization of open array out-parameters is now done properly (using fpc_initialize_array).
+ Test
git-svn-id: trunk@17081 -
- 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)
git-svn-id: branches/svenbarth/classhelpers@17070 -
+ avr: fixed writing of constants in assembler
* avr: fixed reading of constants in assembler
* avr: determine used registers at procedure exit properly
* changed project name to ppavr
git-svn-id: branches/avr@17032 -
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

added comments why (solves duplicate symbol error when adding a category
for an objcclass in the interface and then another one in the
implementation of a unit, problem reported by Ryan Joseph on the
mac-pascal list)
git-svn-id: trunk@16902 -
- 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)
- symdef.pas: adjusted the constructor of tobjectdef to use the new method for adding flags
git-svn-id: branches/svenbarth/classhelpers@16889 -
* 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.
