Add function to search for class helper symbols. This is completely different from the ObjC one (Note to self: rename that function), because in Delphi only one class helper can be in scope at a given time. Also class helper symbols are searched BEFORE the symbols of the class.
So the search works like this:
1) search the last available class helper for the given class
2) search for the given symbol (method/property) in the found class helper (if any)
3) if not found then use the helper parent of the class helper and continue with (2)
Especially step 1 might easily lead to longer compile times if no class helper for a class is in scope, but many units are included. I'll need to test this by cycling the compiler with and without that search and will then decided whether I should think about something better.
Note: Overloaded methods are not yet supported.
git-svn-id: branches/svenbarth/classhelpers@16794 -
* added flag pd_nothelper which tells the "directive parser" not to use this directive with class helpers
* added pd_nothelper flag to definitely forbidden directive (I'm not so happy about "abstract" though, as the error message because of this isn't very descriptive, because abstract is treated as field)
* some directives that are useless in class helpers are forbidden in mode ObjFPC only (e.g. "message", "virtual", "override")
- compiler/pdecobj.pas: as class helpers don't support some concepts used in normal classes (e.g. virtual methods) they are simply ignored and thus the corresponding flags are removed (this is for mode Delphi)
git-svn-id: branches/svenbarth/classhelpers@16793 -
- compiler/symdef.pas: add "helperparent" which contains the class helper the current class helper "inherits" from (its real parent is the extended class); it's saved to ppu as well
- compiler/ppu.pas: increase ppu version
- compiler/pdecobj.pas:
* 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...)
git-svn-id: branches/svenbarth/classhelpers@16792 -
- 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"

- store type parameter in parasymtable, push it to the symtablestack before parsing arguments and return type
- move procedure/function declaration parsing to procvar_dec subroutine
- don't skip parasymtable while searching types because they store type parameters now
- add TParaSymTable.ReadOnly field to prevent adding defs into symtable. Add defs to the parent symtable in this case (we are adding this symtable to stack to read type parameters only, add defs should go to parent in this case as it was before)
git-svn-id: trunk@16719 -
relocations for addr_pic_no_got references (do not go via the GOT)
* fixed code generator so that it generates addr_pic_no_got references
also for platforms that use the internal assembler (this will break linking
of some tests that check static data > 2GB on Linux/x86-64, but they were
already broken before as well because we don't use the "huge" x86-64
execution model)
* fixed x86-64 Linux syscall code to not expect GOT-based relocations for
the system unit's errno variable (it's an implementation-only variable)
git-svn-id: trunk@16717 -
- change id_type to single_type in readImplementedInterfacesAndProtocols to allow use of interface specializations inside class parent block
- change single_type boolean arguments to set, add stoParseClassParent option to that set
- move parse_generic variable assignment from parse_object_members to outer routine to setup it before parsing class parents
- return paticular generic in generate_specialization instead of undefineddef to pass class/interface checks inside parent class block
- add test for delphi mode
- modify tw11431 to be syntatically correct
git-svn-id: trunk@16706 -
- show array symtable
- support unicodestring
- don't read "Last VTable idx" field in case of interface - this entry is not stored in ppu

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
