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

284210ad48 * hardcode offset of the ISA field in Objective-C (meta)classes to be
0, just like gcc/clang. This results in more efficient code on

ceee186f2f * typecheck all array indices, not just integer and boolean types
o allows converting indices to the proper type if required (such as
     variant, mantis #20873)
   o do not create temporary defs for this type checking anymore if not
     necessary
   o makes sure that errors are thrown in case of conversions considered
     as invalid by the compiler rather than that wrong code is silently
     generated (such as in mantis #20873 before this change)

c6ca9e5091 compiler:
- add helper function getansistringcodepage which returns explicitly set codepage or 0 in other case
  - add helper function getansistringdef which return a def with explicitly set codepage or cansistringtype in other case
  - change tstoreddef.createnai constructor to allow set codepage in constructor
  - don't convert string constants to rawbytestring. if string constant already has a codepage - preserve it or convert to ansistring codepage (delphi compatible)
  - don't perform string conversion from ansistring to strings with explicitly set codepage (by directive or by compiler switch) and vice versa (delphi compatible)
  + test which covers most of the cases

979f55e1db + support for procedural variables for the JVM target
o every porocedural variable type is represented by a class with one
     public "invoke" method whose signature matches the signature of the
     procvar
   o internally, dispatching happens via java.lang.reflect.Method.invoke().
     WARNING: while this allows calling private/protected or other methods
     that are normally not accessible from another context, a security
     manger can override this. If such a security manager is installed,
     most procvars will cause security exceptions
   o such dispatching also requires that all arguments are wrapped, but
     that's done in the compiler-generated body of the invoke method,
     so that procvars can also be called conveniently from Java code
   o typecasting between a procedure of object and tmethod is supported,
     as well as Delphi-style replacing of only the method pointer via
     @procvar1=@procvar2.
   o nested procvars are not yet supported, but most of the basic
     infrastructure for them is already present
  * all units/programs now get an internal __FPC_JVM_Module_Class_Alias$
    type when compiled for the JVM target, which is an "external" class
    that maps to the unit name. This is required to look up the
    JLRMethod instances for regular functions/procedures
  + new tabstractprocdef.copyas() method that allows to create a procvar
    from a procdef and vice versa

37aa2d8443 + full support for sets on the JVM target
o sets of enums are handled as JUEnumSet instances, others as JUBitSet
     derivatives (both smallsets and varsets, to make interoperability with
     Java easier)
   o special handling of set constants: these have to be constructed at run
     time. In case of constants in the code, create an internal constsym to
     represent them. These and regular constsyms are then aliased by an
     another internal staticvarsym that is used to initialise them in the
     unit initialisation code.
   o until they are constructed at run time, set constants are encoded as
     constant Java strings (with the characters containing the set bits)
   o hlcgobj conversion of tcginnode.pass_generate_code() for the genjumps
     part (that's the only part of the generic code that's used by the JVM
     target)
   o as far as explicit typecasting support is concerned, currently the
     following ones are supported (both from/to setdefs): ordinal types,
     enums, any other set types (whose size is the same on native targets)
   o enum setdefs also emit signatures
   o overloading routines for different ordinal set types, or for different
     enum set types, is not supported on the JVM target

1dca48bce5 * set reused left node to nil for JVM loadvmtaddrnodes that need to call a

    classrefdefs)

  * don't collect WPO information for Java classes in tloadvmtaddrnode.pass_1()
    (devirtualization can't work for Java, since classes can always be loaded
     at run time, except for final/sealed classes -- but that's not yet
     implemented)

28740dce2d - removed extra "fordefinition" parameter again from tprocdef.mangledname(),
since the definition-specific adorning of JVM mangled names is Jasmin-
    specific, and such code has no place in symdef

0ee702b3a2 * tprocdef.mangledname now gets an extra boolean parameter indicating
whether the mangled name is for defining a symbol, or for referencing
    it later (e.g. for a call or load of its address). The reason is that
    on the JVM both cases are different.
  + jvmdef unit to encode types according to the JVM rules
  + tprocdef.jvmmangledname() to encode a procdef's JVM mangled name
    (the common part of defining/referencing it; tprocdef.mangledname
     afterwards adorns it as required)

20c3809c3a * when a constant Objective-C class reference is used for anything but
the methodpointer of a call, transform it into a call to the classclass
    method because otherwise it can be used before the first call to any
    method of the class (such as in the packages/cocoaint/src/IvarSize test)
    and this can result in crashes

56bf42de57 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

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)

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

    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)
