daef2efa69 - removed tstoreddef.reset() and overrides, and the associated
reset_used_unit_defs()/reset_all_defs() calls:
    o removed resetting tprocdef.procstarttai/procendtai and
      instead check in the debug writers whether the def is
      in the current unit or not to determine whether we should
      write debug info for it
    o use the collected defs in the wpoinfo structure to reset
      the wpo flags in the defs, instead of iterating over all
      defs in the program and resetting them that way
  - removed now unused "is_reset" flag from tmodule

835899524b + support for Objective-Pascal for-in loops ("fast enumerations")
+ {$modeswitch objectivec2}, which is required before you can use
    Objective-C 2.0 features (such as the above). It automatically
    also implies {$modeswitch objectivec1}
  + genloadfield() helper to load a field of a node representing
    a record/object/class

ea4bb9d752 * don't treat variant records with one element as "records with one element"
(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

15e9c54b44 * fixed ABI compliance for parameter passing and function returning on all
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

f5c52b25cd * removed "and not is_class()" condition from is_managed_type(), because
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

1b614b526a compiler:
- 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

9cc211e88e * changed {$align mac68k} from an alias for {$packrecords 2} to a proper
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)

b495fbb991 * let search_class_helper() only return class helper methods; it could
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

5a2ccfff52 --WARNING: start build process with FPC 2.2.4; won't work when
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

b1b9894ae3 * initial Objective-C 1.0 support:
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)
