+ {$modeswitch objectivec2}, which is required before you can use
Objective-C 2.0 features (such as the above). It automatically
also implies {$modeswitch objectivec1}
+ genloadfield() helper to load a field of a node representing
a record/object/class
git-svn-id: trunk@15460 -
(the ABIs that prescribe special treatment for aggregates with one
scalar element don't either, since a "union containing a single scalar"
is not the same as a scalar)
* fixed passing record with a single float field on PowerPC/AIX abi's
* several changes to cgobj and ncgutil to correctly deal with transfering
such records between integer and floating point registers
git-svn-id: trunk@15416 -
x86-64 platforms (except for win64, which uses another ABI and which
already complied to it) + test
* fixed returning records containing 1 single or double field on darwin/i386,
these have to be returned via ST0 instead of as a regular record
* added support for LOC_FPUREGISTER and LOC_MMREGISTER in several places
where they can now occur due to the previous two changes
* made a few internalerrors unique
git-svn-id: trunk@15368 -
tobjectdef.needs_inittable returns false for classes nowadays (and already
since quite some time)
* nevertheless replaced all usages in the compiler of x.needs_inittable with
is_managed_type(x) (in case some other condition is added again in the
future) and removed all remaining accompanying "and not is_class(x)"
checks

- add own symbol table for enumeration to store enumeration elements
- reimplement enumeration member traverse using symbol table instead of firstenum/nextenum - that members are removed
- implement TEnum.Element access syntax - element is searched in the enumeration symtable in this case instead of global/local symtables
- implement {$SCOPEDENUM ON/OFF} local switch
+ tests
git-svn-id: trunk@15051 -
- fix is_visible_for_object to work correctly if symbol is in the objectsymtable but no current_objectdef present
- fix ClassName for nested classes

implementation for mac68k alignment (mantis #15061)
* changed {$align power} from an alias for {$packrecords 4} to an alias for
{$packrecords c}, as Power alignment is the default C alignment for
PowerPC under Mac OS X (it's close to {$packrecords 4}, but not identical)

also return regular objcclass methods before, because these are also
registered under class helper procsyms for future id.anymethod support
* give an error when calling an inherited method from an objccategory
method, if that is not declared in the parent of the extended class
(since calling inherited in an objccategory method is the same as
calling inherited in a method of the extended class; if a method is
replaced, calling inherited will *not* call the original method
from the original class)

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
compiler: don't allow the compiler to choose the non-valid enumerator operator for the for-in loop

starting with a previous 2.3.1 or compiler built from the objc branch
+ added basic objcprotocol support (only for external protocols
currently)
o use in type declaration: "type xp = objcprotocol ... end;"
o when defining a root class that implements it:
"type yc = objcclass(xp) ... end" (note: no support yet
for something like "objcclass(id,xp)" or so)
o when defining a non-root class that implements a protocol:
"type zc = objcclass(nsobject,xp) ... end"
o includes support for "required" and "optional" sections
o no support yet for the objcprotocol(<protocol>) expression
that enables getting a class instance representing the
protocol (e.g., for use with "conformsToProtocol:")
o message names have to specified in protocol declarations,
but if an objcclass implements a protocol, the message names do
not have to be repeated (but if they are, they have to match;
the same goes when overriding inherited methods)
+ allow specifying the external name of Objective-C classes and
protocols, since classes and protocols can have the same name
(and you cannot use the same Pascal identifier in such caseq)
+ added NSObject protocol, and make the NSObject class use it
+ added missing NSObject class methods that have the same name
as instance methods (added "class" name prefix to avoid clashes)
* fixed several cases where the compiler did not treat Objective-C
classes/protocols the same as Object Pascal classes/interfaces
(a.o., forward declarations, alignment, regvars, several type
conversions, ...)
* allow "override" directive in objcclass declarations, and print
a hint if it's forgotten in an external declaration (because it
doesn't really matter there, and may make automated header
conversion harder than necessary) and an error if will be used in
a non-external declaration (because it is not possible to start
a new vmt entry-tree in Objective-C, you can only override parent
methods)
* reject objcclasses/protocols as parameters to typeof()
* don't try to test VMT validity of objcclasses/protocols
git-svn-id: branches/objc@13375 -
o support for declaring external Objective-C classes (see
rtl/inc/objcbase.pas), including derived classes
o support for converting methods of objcclasses into selectors
(see tests/test/tobjc1.pp)
o support for loading from/storing to fields of objcclasses
o support for calling Objective-C methods using regular
Object Pascal syntax (see tests/test/tobjc1.pp)
o some things that are known to be not yet working:
o automatic conversion from ID to objcclasses and back
o declaring and implementing new objcclasses/methods in Pascal code
o debug information (objcclasses are currently plain pointers
as far as the debugger knows)

context of a class. This can be either the class declaration or
a method implementation
* replaced all current_procinfo.procdef._class with current_objectdef

separate list, so that procsyms, constsym, varsyms etc are not checked
and so that every sym is checked only once (rather than at the end
of every type block). This makes parsing units with lots of declarations
much faster (e.g., compiling MacOSAll is now 2 to 3 times faster)
git-svn-id: trunk@11719 -
record variables is now independent of their packrecords setting
(except for packrecords C, which already calculated a reasonable
alignment). This means that e.g. a packed record consisting of two
pointers will be aligned at sizeof(pointer) normally. The internal
alignment of the individual fields of packed records obviously did
not change, also not if those fields are records themselves.
* The size of records without any packing atributes is also padded to
become a multiple of this improved alignment calculation, which
means that the size of such records may change after this patch.
Always explicitly specify a packing for records which are used for
data storage/transmission if you want to have a consistent layout.

(some are still broken, but can't be fixed currently because
def.size/sym.getsize return an aint, which means low(aint)
in case of structures with a size = high(aint)+1)
git-svn-id: trunk@7614 -
* symtables based on TFPHashObjectList and TFPObjectList
* rename torddef.typ to torddef.ordtype
* rename tfloatdef.typ to tfloatdef.floattype
* rename tdef.deftype to tdef.typ
* remove obsolete browser code, browcol is kept so the ide
can still be compiled

Not sure how it ever worked, nor how exactly symtable ppu entries
work -- but it's now stored with the recorddef (which also means
that bitpacking is disabled currently for objects and classes,
since they are based on tabstractrecorddef rather than trecorddef)

vs_written, vs_readwritten. vs_initialised is the old vs_assigned;
vs_used has been replaced by vs_read, vs_written and vs_readwritten
* the valid_for_*() routines in htypechk now get an extra parameter to
decide whether or not errors should be reported
