101f545ad0 compiler: don't allow generic object types (interfaces,dispinterfaces,objclasses,...) to have type,var,const sections if regular object types don't have them. currently only objects, classes and records are allowed to have nested type,var,const sections.

d1026bb052 compiler: reintegrate branch http://svn.freepascal.org/svn/fpc/branches/paul/extended_records
------------------------------------------------------------------------
r16513 compiler: add support for visibility blocks in records and type, const declarations:
  - add parse_record_members function to parse record blocks based on parse_object_members code
  - disable published section in records
  - rename in_class argument in some functions to in_structure because the same code can work for records now which are not classes
------------------------------------------------------------------------
r16514 compiler: check visibility of record members, allow access to record consts and types:
  - add searchsym_in_record function
  - change is_visible_for_object to accept tabstractrecorddef instead of tobjectdef arguments because records also have visibility sections now
  - change arguments in do_member_read, do_proc_call to tabstractrecorddef from tobjectdef to accept records
  - rename classh arguments to structh and change their type to tabstractrecorddef to show that they can accept records now too
  - move RttiName from tobjectdef to tabstractrecorddef
------------------------------------------------------------------------
r16515 compiler: add current_structdef: tabstractrecorddef and point current_objectdef to it
------------------------------------------------------------------------
r16516 compiler: allow access other record symbols than fields, first extended records tests
------------------------------------------------------------------------
r16519 compiler: 
  - move objname, objrealname fields from tobjectdef to tabstractrecorddef, 
  - load and save them from/to ppu file, 
  - use tabstarctrecorddef in some more places where previously code worked for tobjectdef
  - change push_nested_hierarchy, pop_nested_hierarchy to handle records too
------------------------------------------------------------------------
r16526 compiler: implement record methods and class methods:
  - 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,
Allow the next modifiers for records: static
------------------------------------------------------------------------
r16530 compiler: fix compilation problems caused by tprocdef._class -> tprocdef.struct rename which was found by make fullcycle
------------------------------------------------------------------------
r16531 compiler: redo searchsym_type:
  - remove complex condition which was used previosly to decide whether objectsymtable or recordsymtable requires a search for type or not - they require a search because contains types (although not all object types)
  - don't search only for typesym but for other symbols too - for example UnitSym.TypeSym or ConstSym..ConstSym are also valid types. Skip the next symtypes during the search because they can't be used in type declaration: fieldvarsym, paravarsym, propertysym, procsym, labelsym
------------------------------------------------------------------------
r16541 compiler: move objectoptions to tabstractrecorddef because it will be needed for records too
------------------------------------------------------------------------
r16542 compiler: remove unneeded checks and typecasting caused by move of objectoptions into tabstractrecorddef
------------------------------------------------------------------------
r16543 compiler: move constructor, destructor parsers to interface section to allow future use by records + change current_objectdef to current_structdef for the same reason, make constructor return type = record for records
r16544 compiler: start parsing of record constructors and destructors:
  - disallow record destructor
  - raise internal error for constructor because it is not yet implemented
  - handle class constructors and destructors for records
  - move find_procdef_bytype to tabstractpointerdef
------------------------------------------------------------------------
r16545 compiler: fix static fields creation and access for records
+ extend test to check class constructor/destructor for records and static fields access
------------------------------------------------------------------------
r16546 tests: add a test which checks that records destructors are not allowed
------------------------------------------------------------------------
r16547 compiler: rename aclass->astruct in read_property_dec because records will have properties too
------------------------------------------------------------------------
r16548 compiler: implement properties in records:
  - rename property_dec from pdecobj to struct_property_dec because pdecl also has property_dec and move it to interface to use by records + allow properties for records
  - use struct_property_dec in record parser
  - change structh type from objectdef to abstractrecorddef in read_property_dec to use by records
  - disallow stored and default modifiers for records because records are not used for streaming
  - fix misuse of search_sym_in_class for records in few places
------------------------------------------------------------------------
r16550 compiler: disallow regular class methods in records and allow only static class methods. delphi do so and it is logical because records have no inheritance. + tests
------------------------------------------------------------------------
r16560 compiler: a trial to implement record constructor
  - map self to constructor result
  - don't push vmt for records

At the moment generated assembler has errors although node tree is correct
------------------------------------------------------------------------
r16561 compiler: 
  - add mode switch extendedrecords to allow/disallow extended records syntax, add this mode switch to delphi mode by default
  - disable/enable extended records parsing based on extendedreocrds mode switch
------------------------------------------------------------------------
r16562 compiler: fix record constructor return type when parsing procedure declaration
------------------------------------------------------------------------
r16568 compiler: partly revert r16560 and disable (at least temporary) constructors in records
------------------------------------------------------------------------
r16569 test: add records Self test
------------------------------------------------------------------------
r16570 compiler: generate debug info for record methods:
  - extended write_symtable_procdefs to handle record definitions
  - fix stabs info generator to use prefixed symbol names for record methods, also handle records static symbols the same way as for object types
  - fix dwarf info record generation: add visibility info and write methods, also prefix record members the same way as object members

d30952b408 * patch by Aleksa Todorovic which adds the ability to reference current generic class. Each reference to current generic class is "translated" to appropriate specialization of that generic class. There are two tests as part of the patch to test that it works. The patch, also, rejects declaring generic inside another generic. 0010479 is easy to implement with this patch applied, resolves #11777

same way as regular methods as far as overriding is concerned ("override"
    is now allowed, and even required, to override them in a descendent class;

57bd6d2685 + merged nestedprocvars branch
+ 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)

0cfc6e1cac + support for "univ" in macpas mode: a parameter modifier that allows
passing any value to that parameter which has the same size as the
    parameter (it basically acts as if there is an explicit type conversion
    to the parameter type around the value at the caller side). If a procvar
    has an univ parameter, all procvars whose corresponding parameter
    has the same size as that univ parameter are similarly compatible.

    This transparent compatibility can however cause crashes in case of
    of the procvars when one of the types is passed on the stack and the
    other isn't (because then the called routine will a) load the parameter
    from a wrong location and b) pop the wrong amount off of the stack at
    then end). Therefore FPC will warn in most cases where this can happen.

d1538ab023 o added ARM VPFv2/VFPv3 support:
+ RTL support:
      o VFP exceptions are disabled by default on Darwin,
        because they cause kernel panics on iPhoneOS 2.2.1 at least
      o all denormals are truncated to 0 on Darwin, because disabling
        that also causes kernel panics on iPhoneOS 2.2.1 (probably
        because otherwise denormals can also cause exceptions)
    * set softfloat rounding mode correctly for non-wince/darwin/vfp
      targets
    + compiler support: only half the number of single precision
      registers is available due to limitations of the register
      allocator
    + added a number of comments about why the stackframe on ARM is
      set up the way it is by the compiler
    + added regtype and subregtype info to regsets, because they're
      also used for VFP registers (+ support in assembler reader)
    + various generic support routines for dealing with floating point
      values located in integer registers that have to be transferred to
      mm registers (needed for VFP)
    * renamed use_sse() to use_vectorfpu() and also use it for
      ARM/vfp support
    o only superficially tested for Linux (compiler compiled with -Cpvfpv6
      -Cfvfpv2 works on a Cortex-A8, no testsuite run performed -- at least
      the fpu exception handler still needs to be implemented), Darwin has
      been tested more thoroughly
  + added ARMv6 cpu type and made it default for Darwin/ARM
  + ARMv6+ implementations of atomic operations using ldrex/strex
  * don't use r9 on Darwin/ARM, as it's reserved under certain
    circumstances (don't know yet which ones)
  * changed C-test object files for ARM/Darwin to ARMv6 versions
  * check in assembler reader that regsets are not empty, because
    instructions with a regset operand have undefined behaviour in that
    case
  * fixed resultdef of tarmtypeconvnode.first_int_to_real in case of
    int64->single type conversion
  * fixed constant pool locations in case 64 bit constants are generated,
    and/or when vfp instructions with limited reach are present

  WARNING: when using VFP on an ARMv6 or later cpu, you *must* compile all
    code with -Cparmv6 (or higher), or you will get crashes. The reason is
    that storing/restoring multiple VFP registers must happen using
    different instructions on pre/post-ARMv6.
