5a344ee263 Rework the way how "specialize" is handled. Instead of initializing the specialization of a full type declaration (including unit name and parent types) it is now considered part of the specialized type itself. This means that for example the following code:
type
  TTestLongInt = specialize SomeOtherUnit.TTest<LongInt>;

will now have to read as

type
  TTestLongInt = SomeOtherUnit.specialize TTest<LongInt>;

While this is not backwards compatible this situation should arise seldomly enough and the benefits especially in context with generic functions/procedures/methods outway the drawbacks.

pbase.pas:
  * try_consume_unitsym: add a allow_specialize parameter that allows to parse "specialize" in front of a non-unit symbol; whether it was a specialization or not is reported using a new is_specialize parameter
  + add a new overload try_consume_unitsym_no_specialize that calls try_consume_unit sym with allow_specialize=false and a dummy is_specialize parameter
  * switch calls to try_consume_unitsym to try_consume_unitsym_no_specialize
pstatmnt.pas, try_statement:
  * switch call to try_consume_unitsym to try_consume_unitsym_no_specialize
  * adjust call to parse_nested_types
ptype.pas:
  + extend id_type with the possibility to disallow unit symbols (needed if a specialize was already parsed) and to report whether a specialize was parsed
  + extend parse_nested_types with the possibility to tell it whether specializations are allowed
  * have parse_nested_types specialize generic defs if one is encountered and local type defs are allowed
  * id_type: only allow "unitsym.specialize sym" or "specialize sym", but not "specialize unitsym.sym"
  * single_type: correctly handle specializations with "specialize" keyword
  * read_named_type.expr_type: there is no longer a need to check for "specialize" keyword
pexpr.pas:
  + new function handle_specialize_inline_specialization which tries to specialize a type symbol
  * handle_factor_typenode: handle specializations after a point that follows a record or object (why isn't this part of postfixoperators anyway? O.o)
  * postfixoperators: handle "specialize" after records and objectdefs
  * factor_read_id: handle "specialize" in front of an identifier (and after unit symbols)

+ added tests
* adjusted test webtbs/tw16090.pp

c730e16031 * changed the syntax for block procvars from "xxx is block" to

bd09b88a5b + support for http://en.wikipedia.org/wiki/Blocks_(C_language_extension)
o blocks are implemented as a variation of procedure variables
   o declaration of a block variable: "test: procedure(c: char) is block;"
     (C equivalent: (void)(^test)(char c) )
   o the compiler automatically converts procedures/functions whose address
     is passed to a block parameter or assigned to a block variable into
     a "block". This consists of
    1) generating a block descriptor (containing the size of the "block
       literal" (see below) and the signature of the invocation function
       encoded as an Objective-C selector)
    2) generating a wrapper function around the original funcion (with C
       calling convention), that has an extra first hidden parameter
       (marked as vo_is_parentfp in the compiler) whose type is a pointer
       to the describing "block literal"
    3) generating the "block literal", which contains a pointer to an
       external variable indicating whether this block captures context or
       not, some flags (see compiler/blockutl.get_block_literal_flags for
       info), a pointer to the wrapper function and a pointer to the
       descriptor. In the future, it will also contain captured variables.
   o right now, only global procedures/functions can be converted to blocks
     (because they don't require state capturing). The next steps are (Object
     Pascal) methods (not Objective-C methods, because Objective-C method
     procvars don't exist) and finally nested functions
   o on Mac OS X, the functionality will only work on Mac OS X 10.7 and later,
     because we have to use the so-called "ABI.2010.3.16" to ensure that
     our blocks aren't called as variadic functions by the runtime (which
     came out after the Mac OS X 10.6 release)
   o while the currently implemented functionality does not require any
     library support at all, there's no use enabling it on other platforms
     because unless it has been confirmed to work with a blocks runtime,
     there's no point in using blocks (they're just somewhat bulky procvars
     right now). Enabling it on other platforms (in combination with the
     GNUStep Objective-C run time), should simply be a matter of adding
     the right {$linklib xxx} statement to rtl/inc/blockrtl.pp file, adding
     that file to Makefile.fpc for that platform and adding that platform
     to the compiler/systems.systems_blocks_supported set

639a59df92 Added support for partial specialization. This should fix a few problems with generics, the tests for which will be added in the next days after I've verified them.
For partial specialization only the declaration is reparsed, but not method bodies.

The way generic parameters are passed around inside the compiler is changed: instead of creating new type symbols we keep a (name,def) pair so that the code in insert_generic_parameter_types can decide whether it needs to add a type symbol (for new undefined defs) or not (for real types and undefined defs that were passed on from the parent generic). This required the tfpobjectlist type of the genericlist variables/parameters to be changed to tfphashobjectlist.

For correctly parsing Delphi specializations as parameters in functions of records (or objects) the relationship between the def and its typesym must already be established during the parsing. For this the checks for forcing a "type is not completely defined" message needed to be adjusted to correctly handle nested types as well. This should as a sideeffect also allow the usage of nested constants, etc like was fixed for classes some months ago.

ToDo: 
  - if a generic is specialized with only fully defined types then we could generate the in the unit where it's used. This is not yet done.
  - currently we don't specialize generics that are currently parsed; maybe this could be improved in the future for better type compatibility checks
  - check whether the pausing of token recording for partial specializations works correct in context of hint modifiers

pgenutil.pas:
  * parse_generic_parameters: return a tfphashobjectlist instead of a tfpobjectlist (requires a few type adjustments in various other declarations)
  * maybe_insert_generic_rename_symbol, insert_generic_parameter_types: change genericlist from tfpobjectlist to tfphashobjectlist
  * parse_generic_specialization_types_internal: use is_generic instead of checking for df_generic
  * generate_specialization:
      + add a nested function to disable the requirement to check for method bodies
      * use the "simple" parameter parsing only for error recovery
      * instead of already creating a new type symbol for a parameter we use the found symbol's name and its def and maybe create it later on (therefor the type of tfpobjectlist was changed to tfphashobjectlist)
      * a partial specialization is specialized into the symtable of the def it is specialized in instead of one of the two global symtables
      * for now we handle partial specializations of generics we are currently parsing like before
      * don't continue recording generic tokens while we do a partial specialization
      * use the new unset_forwarddef function on the newly created defs
  * insert_generic_parameter_types: only create a new type symbol if the found type symbol does not yet have an owner (thus was freshly created for this generic declaration)

pdecobj.pas, object_dec:
  * change type of genericlist from tfpobjectlist to tfphashobjectlist
  * set the type sym for all object types that can be generic or inside a generic (needed for correctly parsing Delphi style generic declarations)

pdecsub.pas, parse_proc_head:
  * consume_generic_interface: always generate the specialization name as now all generics are "specialized" inside a generic
  * the assumption that the def index numbers are the same is no longer true as the genericdef might contain the defs of partial specializations which are not generated for full specializations

pdecvar.pas, read_record_fields:
  * we also need to check nested types whether they contain a not yet completely parsed record or object

ptype.pas:
  * read_named_type: 
      * change genericlist from tfpobjectlist to tfphashobjectlist
      * pass the typesymbol along to record_dec
  * resolve_forward_types: use is_generic instead of checking for df_generic
  * single_type: 
      * use is_generic instead of checking for df_generic
      * no need to check generic parameters
  * parse_record_members:
      + add parameter for the record's type symbol
      * setup the typesym <=> def relationship
  + record_dec: add parameter for the type symbol and pass it to parse_record_members
  * read_named_type, expr_type: use is_generic instead of checking for df_generic
  * array_dec & procvar_dec: change genericlist from tfpobjectlist to tfphashobjectlist

symdef.pas, tstoreddef:
  * improve the checks used in is_generic and is_specialization to really only work on true generics and true (and partial) specializations respectively
  * don't search the type parameters in the symtable, but store them in the PPU and load them from there
  - remove fillgenericparas method (including the calls in the descendants tarraydef, tprocvardef, tobjectdef and trecorddef)

defcmp.pas, compare_defs_ext:
  * handle partial specializations: specializations with only undefineddefs are compatible to generic defs

pdecl.pas, types_dec:
  * switch generictypelist from tfpobjectlist to tfphashobjectlist

ppu.pas:
  * increase PPU version

+ added tests that ensure that "not completely defined" checks for records (and objects) still work correctly

b57c95043f + support overriding tdef/tsym methods with target-specific functionality:
o made all (non-abstract) tdef and tsym constructors virtual
   o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
     class
   o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
     class from the base classes, and initialises the c*def/c*sym classes with
     them. This is done so that the llvm target will be able to derive from
     the tcpu*def/sym classes without umpteen ifdefs, and it also means that
     the WPO can devirtualise everything because the c* variables are only
     initialised with one class type
   o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
     calls

4adb36e8da Add support for generic type constraints. They are currently only useful to stop specialization of a generic. The parsing of a generic is still too lax and needs to be changed in the future...
symconst.pas:
  + extend "tdefoptions" by a "df_genconstraint" which will be used to mark dummy defs that should mainly satisfy the compiler's type checking without to much changes
symsym.pas:
  + add a class "tgenericconstraintdata" which will hold information about the constraints associated with a specific generic type parameter (designed for future extensions)
  + extend "ttypesym" by a reference to a "tgenericconstraintdata" which is written to the ppu only if needed
symtype.pas:
  + add a pointer to "tderef" as this is needed for the ppu reading/writing code for the "tgenericconstraintdata"
pdecl.pas, types_dec:
  + call "parse_generic_parameters" so that constraints are allowed
pgenutil.pas:
  + extend "generate_specialization" by a "parsedpos" to give in the file position of the first parsed parameter (needed for correct error locations when checking the constraints)
  + add an overloaded call of "generate_specialization" to differentiate between the use cases "first parameter parsed by generate_specialization" and "first parameter parsed by other code"; this also allows to write the "fillchar" for the "parampos" parameter only once ( => otherwise a warning is triggered => error in compilation)
  + extend the "parse_generic_specialization_types" by a "poslist" parameter which will contain the positions of all parsed type parameters (can only be used in the case that all parameters are parsed)
  * move the original code of "parse_generic_specialization_types" to a new procedure "parse_generic_specialization_types_internal" which take an additional "parsedpos" parameter which will be added to the "poslist" before all others; "parse_generic_specialization_types" calls this new procedure with a dummy argument (which won't be used)
  + extend "parse_generic_parameters" by the parsing of generic constraints which constructs correct defs for the parameters and fills in the new "tgenericconstraintdata" object for each parameter (note: the "constructor" constraint is only parsed for Delphi compatibility and basically means the same as a "class" constraint... (it's a relict of Delphi.NET))
  * adjust "insert_generic_parameter_types" as specializations and generics can no longer be differed by whether the type parameters are of type "undefineddef"
pdecsub.pas, parse_proc_head, consume_generic_interface:
  * adjust call to "generate_specialization"
  + add a new function "check_generic_constraints" which is used from within "generate_specialization" to ensure that the given specialization parameters are compatible with the constraints of the generic parameters
ptype.pas:
  * single_type: adjust call to "generate_specialization"
  * read_named_type, expr_type: adjust call to "generate_specialization"
  + write_persistent_type_info: don't write typeinfo for constraints
pexpr.pas, sub_expr:
  * adjust call to "generate_specialization"
* adjusted ppudump, because of added "tdefoptions.df_genconstraint" value

+ added tests for generic constraints
* modified test for class helper inside a generic which extends a class type parameter
+ added test for record helper inside a generic which extends a record type parameter

64740049bf * fix for mantis #22796: add alignment padding to records before inserting
hidden parameters while parsing the interface, because they may depend on
    the padded size (since the size was not yet padded in the interface and
    padded in the implementation, this could result in differences)

3798b79fd7 + optimization that (re)orders instance fields of Delphi-style classes in
order to minimise memory losses due to alignment padding. Not yet enabled
    by default at any optimization level, but can be (de)activated separately
    via -Oo(no)orderfields
   o added separate tdef.structalignment method that returns the alignment
     of a type when it appears in a record/object/class (factors out
     AIX-specific double alignment in structs)
   o changed the handling of the offset of a delegate interface
     implemented via a field, by taking the field offset on demand
     rather than at declaration time (because the ordering optimization
     causes the offsets of fields to be unknown until the entire
     declaration has been parsed)

f9211271d5 Fix for Mantis #22154:
* ptype.pas, read_named_type, array_dec: 
  allow border checks if both range elements are orddefs; for normal arrays
  using e.g. "0..15" this will allow to declare the correct amount of
  elements in the initialization while for generic arrays (e.g. "0..SizeOf(T)") 
  this will mean that only one element can be declared, which was already the 
  case before this change (maybe in such cases a constant initialization should 
  be forbidden in the future...)
+ added test

ptype.pas:
  * read_named_type:
      allow specializations for pointers in Delphi modes
  * single_type: 
      correctly handle forwarddefs; as we can only specialize generics if
      they are completely defined (srsym<>nil) we don't need to return a 
      forward def, but instead return the specialized def itself
+ added tests to "test" instead of "webtbs" as no explicit tests were given 
  in the report

8c95ea039f Fix for Mantis #22219
ptype.pas:
  * read_named_type: 
      after reading the type we're pointing to we need to make sure that
      we didn't get a generic dummy symbol; this can happen when parsing
      a pointer declaration as the type in a constant or variable 
      declaration
  * resolve_forward_types:
      when resolving forward types we need to make sure that we weren't
      given a generic dummy to which no non-generic definition was
      given (possible in Delphi mode); for non-Delphi modes we can not
      rely on the generic dummy flag as the typedef of the symbol will
      the generic def
+ added test from the bug reports as well as three additional ones to
  make sure that nothing breaks regarding to forward pointer 
  declarations

d2fabd2a22 Fix for Mantis #21350
+ pgenutil.pas: 
    add a procedure which adds a type symbol to a non-Delphi-mode generic class or record which has the same name as the unit global dummy symbol for that generic. I don't know why I had that idea earlier as this will simplify some of the conditions in the parser again (I haven't changed these yet, but I hope to do that at least when I start working on generic functions).
* pgenutil.pas, generate_specialization:
    correctly handle "specialize TSomeGeneric<T>" as method parameter in a generic with the newly added rename symbol
* pdecobj.pas, object_dec & ptype.pas, record_dec: 
    call the procedure to add the rename symbol (the procedure checks whether the mode is correct)
* ppu.pas: 
    increase PPU version so that we don't use non-Delphi mode units with generics, but without the rename symbol
+ added tests:
    the one in webtbs are for classes/objects and those in test are for records

dbc410de63 Allow the usage of a generic's name without type arguments inside of nested classes inside the generic. This fixes Mantis #19499, but also Mantis #18688.
* symtable.pas:
    + add function "get_generic_in_hierarchy_by_name" which returns a def with the name of the symbol in the given object/record hierarchy (useful only in non-Delphi modes)
    + add function "return_specialization_of_generic" which returns the specialization def of a given class inside the given object/record hierarchy
* pexpr.pas, factor, factor_read_id: instead of checking whether the names of the found symbol and the current_structdef are equal, check whether the generic appears in hierarchy of current_structdef
* ptype.pas:
    * id_type: check whether the found symbol is a generic dummy and we are currently parsing a generic then return the correct def of the generic instead of the dummy one
    * single_type: when using the generic type without type parameters the def must resolve to the specialized def when specializing the class instead of the generic def which the dummy symbol points to
    * read_named_type, expr_type: like in "single_type" we need to resolve the use of the parameterless type name to the correct specialization def instead of the generic def
* pdecobj.pas, object_dec: also set the typesym of the current_structdef as otherwise some assumptions about generics with the above mentioned changes aren't valid anymore (like the def the typesym is unset again afterwards)
+ add tests for both bug reports (the one for 19499 is slightly modified so that it does not contain any errors)
