- 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,

don't have any parameters in most expressions, rather than using them

the procvar); necessary in combination with the next fix to compile

type then interpret it as the current function definition, otherwise
as the current function result) (mantis #17379)

+ support for nested procedural variables:
o activate using {$modeswitch nestedprocvars} (compatible with all
regular syntax modes, enabled by default for MacPas mode)
o activating this mode switch changes the way the frame pointer is
passed to nested routines into the same way that Delphi uses (always
passed via the stack, and if necessary removed from the stack by
the caller) -- Todo: possibly also allow using this parameter
passing convention without enabling nested procvars, maybe even
by default in Delphi mode, see mantis #9432
o both global and nested routines can be passed to/assigned to a
nested procvar (and called via them). Note that converting global
*procvars* to nested procvars is intentionally not supported, so
that this functionality can also be implemented via compile-time
generated trampolines if necessary (e.g. for LLVM or CIL backends
as long as they don't support the aforementioned parameter passing
convention)
o a nested procvar can both be declared using a Mac/ISO Pascal style
"inline" type declaration as a parameter type, or as a stand-alone
type (in the latter case, add "is nested" at the end in analogy to
"of object" for method pointers -- note that using variables of
such a type is dangerous, because if you call them once the enclosing
stack frame no longer exists on the stack, the results are
undefined; this is however allowed for Metaware Pascal compatibility)

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

for properly synchronizing regvars after loops. The absense of this
causes the crash in the test program of mantis #11290 under 2.2.1,

* preprocess rather than postprocess the replaceparaloads in ncal
when inlining, because after r8558 a node is now sometimes replaced
by a tree which still contains this same node (so postprocess
causes endless recursion in those cases)
git-svn-id: trunk@8561 -
* rename methodpointerinit/done to callinitblock/callcleanupblock
* moved checks in callnode to separate functions
* funcretnode is now always a simple node instead of a block of
statements
* funcret and methodpointer are generated/optimized only in pass_1 so
a conversion from calln to loadn is much easier
* function result assignments are much more often optimized to use the
assignment destination location instead of using a temp
