68a3827539 Fix for Mantis #21051. Correctly handle specializations that occur during the specialization of methods.
cclasses.pas:
  + TFPHashList & TFPHashObjectList: add WhileEachCall methods that walk the list like ForEachCall does, but uses a while-loop instead of a for-loop
psub.pas, generate_specialization_procs:
  * use WhileEachCall instead of ForEachCall as new defs can be added during the specialization that need to be specialized as well

+ added test

fc79d47b09 Fix for Mantis #24651. Allow pointer comparison for internal expressions (in this case check for valid VMT).
nadd.pas, taddnode:
  + add new constructor "create_internal" which adds "nf_internal" to the node's "flags"
  * pass_typecheck_internal: allow pointer comparisons other than "=" and "<>" for nodes which have "nf_internal" set
psub.pas, generate_bodyentry_block:
  * create the addnode using "create_internal" instead of "create" to allow the pointer comparison

+ added test

344571cb4e Added support for type helpers. In non Delphi modes they use "type helper" and in mode Delphi they use "record helper". They can also be used on constants.
symconst.pas:
  + extend "thelpertype" by "ht_type" which tells the code in "pdecobj.parse_extended_type" that a type helper declaration has been parsed
node.pas:
  + add a constant which identifies all constant node types
ptype.pas:
  + read_named_type: add a parameter "hadtypetoken" to tell the code whether a "type" token had been parsed before
  + read_named_type: if an identifier "helper" is parsed we need to check whether "hadtypetoken" is true and the modeswitch "m_class" is set, but the "m_delphi" one is not; in that case we have a "type helper" declaration
pgenutil.pas, generate_specialization:
  * adjust call to read_named_type
pdecl.pas, types_dec:
  * adjust call to read_named_type

pdecobj.pas:
  * parse_extended_type: extend for correct handling of primitive types (includes Delphi compatible handling as well) and reject types that are explicitly not allowed
  * method_dec: require "static" for class methods in type helpers
  * method_doc: allow constructors for type helpers as well
paramgr.pas, tparamanager:
  * set_common_funcretloc_info: handle type helper constructors like record constructors
  * handle_common_ret_in_param: the "self" value of a type helper constructor is also returned in a parameter
pexpr.pas:
  + add a function to postfixoperators which tries to find and apply a type helper for a given type
  * postfixoperators: try to apply type helpers for ordinal constants
  * postfixoperators: use the correct string type for string constants
  * postfixoperators: try to apply type helpers for enum constants
  * postfixoperators: try to apply type helpers for arrays
  * postfixoperators: try to apply type helpers for Variant
  * postfixoperators: try to apply type helpers for pointer types
  * postfixoperators: try to apply type helpers for other types
  * factor: check postfixoperators after _REALNUMBER, _CCHAR, _CWCHAR, _TRUE and _FALSE
  * factor: also check postfixoperators if a _POINT follows a _NIL

symdef.pas, tdefawaresymtablestack.addhelpers:
  * use "generate_objectpascal_helper_key" to generate the key
symtable.pas:
  + add function to generate the key value for the map of extended types using the extended def
  * adjust "search_last_objectpascal_helper" and "search_objectpascal_helper" to handle primitive types as well
  * use the new "generate_objectpascal_helper_key" function to generate the key

pparautl.pas:
  * insert_self_and_vmt_para: don't insert the $vmt symbol for record or type helpers (ToDo: check whether class helpers really need the symbol as well)
  * insert_self_and_vmt_para: pass "self" as var parameter for type helpers as well
psub.pas, generate_bodyentry_block: 
  * also allow type helpers for constructor methods
ncal.pas, tcallnode.gen_self_tree:
  * also use a temp variable for type helper constructors
ncgcal.pas, tcgcallnode.secondcallparan:
  * allow Pointers to be passed as address param if it is the Self value of a type helper extending a pointer type
  * correctly handle the location in case of type helper constructors

+ add tests

bc0c94c204 fpcdefs.inc: Set fpc_compiler_has_fixup_jmps for powerpcXX and mips CPUs.
psub.pas: Use new fpc_compiler_has_fixup_jmps conditional.
 mips/aasmcpu.pas: MIPS specific fixup_jmps function,
   The insttruction distance calculation is not exact as
   some pseudo-instruction can be expanded to a variable number of real instructions
   real calculation would only be possible if we first 
   convert pseudo-instuctions to real instructions before calling fixup_jmps.

 ncgutil.pas: Revert commit r21791
 ncgcon.pas: Revert commit r21786
 mips/cgcpu.pas: Partial revert of commit r21798, no need to always use A_J,
 as fixup_jmps now handles out of range branches.

aee5380ae0 * merged trunk up to r20882
o support for the new codepage-aware ansistrings in the jvm branch
   o empty ansistrings are now always represented by a nil pointer rather than
     by an empty string, because an empty string also has a code page which
     can confuse code (although this will make ansistrings harder to use
     in Java code)
   o more string helpers code shared between the general and jvm rtl
   o support for indexbyte/word in the jvm rtl (warning: first parameter
     is an open array rather than an untyped parameter there, so
     indexchar(pcharvar^,10,0) will be equivalent to
     indexchar[pcharvar^],10,0) there, which is different from what is
     intended; changing it to an untyped parameter wouldn't help though)
   o default() support is not yet complete
   o calling fpcres is currently broken due to limitations in
     sysutils.executeprocess() regarding handling unix quoting and
     the compiler using the same command lines for scripts and directly
     calling external programs
   o compiling the Java compiler currently requires adding ALLOW_WARNINGS=1
     to the make command line

bd19a16be9 Add support for Default() intrinsic. For now this is only (fully) supported
in code and not in constants. In the case of primitive types constant nodes
are used while complex types like arrays, records and objects use a local
variable which is initialized to zero once at the entry of the method (the
variable is reused if Default() is used for the same type multiple times in
the same method). For this a new compilerproc was added which uses FillChar
to initialize the given memory area to zero.
This fixes Mantis #9420.

+ psystem.pas: Added Default symbol to system unit
+ htypechk.pas: Added function "is_valid_for_default" which checks recursively
                whether the given type can be used with Default at all. 
                Forbidden types are files, helpers, ObjC and C++ types. This
                check is used for records, arrays and objects only if the mode
                is a non-Delphi one, as Delphi ignores these types on lower
                levels.
+ msg/errore.msg: Added error message for unsupported types for Default()
+ symconst.pas: Added a new enum value vo_is_default_var which is used for the
                local variables utilized by Default() so their initalization
                and finalization can be avoided.
+ pexpr.pas: Add handling of Default() intrinsic to "statement_syssym"
+ ninl.pas: Extended tinlinenode by a method which returns the correct node for
            a Default() and used that method in handle_typecheck.
* ncgutil.pas: Check for new flag "vo_is_default_var" when initializing and
               finalizing local variables.
* ppu.pas: increase PPU version
+ psub.pas: 
  * Added a new routine which zeros defaultvars of a symtable.
  * Use this routine inside "initializevars".
  * Also use this routine to initialize the staticsymtable of the unit/program.
* Adjusted ppudump, because of the new enum value.
+ Added implementation of fpc_zeromem to system unit.
+ Added tests for Default()
