1ac4021178 * moved po_has_inlininginfo from procoptions to procimploptions so that
the availability of the body of a function declared as "inline" no
    longer changes the CRC and hence no longer triggers recompilations

956b26bc97 Completely reworked implementation of generic constraints, by moving the generic constraint data from the symbols to the definitions (I originally thought that this would simplyfy things, but the more correct approach is to add it to the defs).
symsym.pas:
    - remove "tgenericconstraintdata" and any using/loading/writing of it in "ttypesym"
    - remove "tgenericconstraintflag"
symdef.pas:
    + add "tgenericconstraintdata"
    + load and write "genconstraintdata" in "tstoreddef"
symconst.pas:
    + add "tgenericconstraintflag" so it can be used in "ppudump" as well
defcmp.pas, compare_defs_ext:
    * as we allow global operator overloads we can't really determine whether two defs are compatible, because a valid operator for the specialization types might just happen to be in scope of the generic; so for now constraints are only strictly checked when declaring a specialization
pgenutil.pas:
    * adjust "parse_generic_parameters" and "check_generic_constraints" to the new location of the constraint data
ppudump.pp:
    * corrrectly parse defs which contain generic constraints

f1f89c77c3 Finally refactor "b_needs_init_final" flag to be a symtable flag which is written to/loaded from the PPU (as discussed in the thread "Status report for "class helpers"" in fpc-devel on 29th January 2011).
symconst.pas:
    + add "sto_needs_init_final" value to "tsymtableoptions"
symtable.pas:
    - TStoredSymtable: remove "b_needs_init_final"
    + TStoredSymtable: add "init_final_check_done" (which is False by default)
    * TStoredSymtable.ppuload: set "init_final_check_done" to True if PPU is loaded (because the flag will then already be restored)
    * TStoredSymtable.needs_init_final: check the symbols only if "init_final_check_done" is not set yet
    * TStoredSymtable._needs_init_final: only check the symbol if "sto_needs_init_final" is not set yet and set the flag accordingly if needed
utils/ppuutils/ppudump.pp:
    * respect the new flag

168c9d152f Small optimization for the search of operator overloads. Add a flag "sto_has_generic" to all symtables that contain an operator overload (the flag propagates up the owning symtables) and check this flag when searching for units with operators.

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

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

4aa05f5133 + support for automatically generating setters/getters for properties on the
JVM target, since Java bytecode itself has no support for properties and
    hence exposing properties to external Java code can only be done through
    getters/setters. Use the new parameters to do so:
      -CTautogetterprefix=XXX
      -CTautosetterprefix=YYY
    The getter/setter will get the same visibility as the property. If a
    getter/setter with the same naming convention was already specified for a
    property and this getter/setter is declared in the same class as the
    property, then the visibility of this existing getter/setter is
    modified and no new routine is generated.

    Newly generated getters/setters are virtual methods, because that is
    the only way in Java bytecode to allow redefining these getters/setters
    in child classes. However, that also means that using these switches can
    change the behvaviour of code, since normally the used property definition
    is only determined by the declared type of its associated class instance,
    and not by the actual instance type. The compiler will therefore warn when
    such an automatically generated getter/setter is overridden by another
    automatically generated getter/setter in a child class.

29c71d39ac Preparations for upcoming work on generics:
+ symconst.pas: add a new flag to symtables to mark them as containing at least one generic (will be used to decide whether an expression like "Foo<Bar" should even remotely be considered a specialization)
* utils/ppudump.pp: respect the new flag
* pdecl.pas, types_dec: add the flag for every generic we have parsed
* pgenutil.pas, generate_specialization: add the flag to the specialize symtable if a nested generic set it for the temporary symtable (does not happen currently, but will in the future when nested generics are supported)
+ keep references to all generic para symbols in the def; this way the symtable containing the type parameters does not need to be walked every time we need to do something with the parameters

a26bc50ca6 compiler: change ShortString->(Some)String and AnsiString->(Some)String overload precedence both for variables and string constants, change unicode constant type from widestring to unicodestring (Delphi compatibility)
new ShortString->(Some)String precedence: ShortString, UTF8String, AnsiString, AnsiString(CodePage) and RawByteString, UnicodeString, WideString and other string types
new AnsiString->(Some)String precedence: RawByteString, UTF8String, AnsiString, AnsiString(CodePage), UnicodeString, WideString, ShortString and other string types

The new logic makes UTF8String more preferrable than other AnsiString types, AnsiString more preferrable than other  AnsiStrings(codepage) and also makes UnicodeString more preferrable than WideString.

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()

9cb16c950f This fixes Mantis #20851 .
For the solution symbols will now contain a "sp_explicitrename" flag if they
were created through a type rename. This is necessary, because we can't
decide whether a type is a renamed generic para which contains by default a
reference to the default undefined def. Using individual undefined defs will
lead to duplicate identifiers as they are created before a symtable was
pushed (thus they'll ba part of whatever symtable is at the top). 

+ symconst.pas, tsymoption:
        Add a new option "sp_explicitrename" which will be used to track type
        renames.
+ pdecl.pas, type_dec:
        Set the new flag if we're dealing with a type rename
* pexpr.pas, factor_read_id:
        If we have an undefined def that is also a rename then we assume that
        it's a rename of a generic parameter
* utils/ppudump.pp:
        Adjustment because of change to tsymoption
* utils/ppu.pp:
        Increase PPU version

commit 7ef252de8023494ee6d39910e289f9e31658d47b
Author: Sven Barth <pascaldragon@minerva>
Date:   Mon Nov 21 17:13:36 2011 +0100

    Fix the compilation of inline specializations of which the generic is derived from another generic.
    
    pgenutil.pas, generate_specialization:
    * Set the "block_type" to "bt_type" when parsing the type parameters, so that the nodes are returned as "ttypenode" instead of e.g. "tloadvmtaddrnode" in case of classes outside of type sections.
    * Set the "block_type" to "bt_type" before calling "read_name_type", so that no unexpected sideeffects happen, because types like classes normally only are declared inside type sections (e.g. for the case a generic class is derived from another generic class a classrefdef for the specialized parent class will be created inside the derived specialized class if the block type is not a type one).

commit 1041a8f7a3a41f4fdf2975ce40055c698281ce71
Author: Sven Barth <pascaldragon@minerva>
Date:   Fri Nov 18 19:03:50 2011 +0100

    Improve inline specializations a bit, so now expressions like "TSomeGeneric<TSomeType>.SomeClassProc OP SomeNonGeneric" is possible. Using another class function of a generic as the right side is not yet working (that still needs some thinking).
    
    To achive this the generalization code must basically continue directly after the "factor" call, so that the operator and the right side are correctly parsed when walking up the call stack. This is done by jumping from the end of the specialization code in the "<"-case to the start of "sub_expr". The freshly generated node (in the above example a callnode) will be passed down the callstack through a new parameter "factornode". If that is set (currently only in the case of a specialization on the left side) "factor" won't be called and the right side will be parsed with the "factornode" as the left side. If it is not set (which is the case for all other calls to "sub_expr" in the unit) then the usual call to "factor" will be done and the result will be used as the left side.

    nld.pas:
    Extend ttypenode by a reference to the type symbol. Normally this is simply the typesym of the given def, but for specializations in type sections of generics this is not the case, because generate_specialization will return a reference to the generic definition and not the new one (thus the symbol will be wrong).
    
    ppu.pas:
    Increase PPU version because of the extension of ttypenode.
    
    pexpr.pas:
    * handle_factor_typenode: Extend the function by a "sym" parameter which will normally be "nil". In that case it is set to the def's typesym. The "typesym" field of the created type node is then set to this sym.
    * For now pass nearly always "nil" for the above mentioned sym except inside factor_read_id when we've encountered a typesym.
    
    ptype.pas, read_named_type, expr_type:
    Exchange the "is_owned_by" check with a "sym_is_owned_by" check so that we can correctly detect that we are using a specialized type declaration inside a generic (once nested generic are allowed this condition needs to be checked).

    * tcgprocinfo.parse_body: Methods of generic classes need to set "parse_generic" as well, so that variables for "stacked generics" (generic array => generic record) inside the method body are handled correctly.
    * specialize_objectdefs: Don't try to generate method bodies for abstract methods.
    
    pdecvar.pas, read_property_dec:
    Allow specializations for the return types of properties (should they be allowed for index types as well?).
    
    symtable.pas:
    Add a new class "tspecializesymtable" which is basically a globalsymtable but is always assuming to be the current unit. This symtable is used in "generate_specializations" (see below) and is needed to allow visibilty checks for "private", etc. to succeed.
    
    pgenutil.pas, generate_specializations:
    Instead of hackily pushing a symtable that may contain conflicting symbols onto the symtable stack for the specialization, a temporary global symtable using the above mentioned "tspecializesymtable" is created and pushed. After the specialization is done all symbols and defs that were added to the temporary symtable are moved to their final symtable (either the global- or localsymtable of the unit, depending on the current position of compilation). This way symbols are correctly added to a top level symtable, but without potential side effects like resolving the wrong symbol.

a1e0b833b2 compiler: fix ppu read/write of property parameters symtable (bug #0020454)
- add new property option ppo_overrides for property which overrides parent class properties
  - write overriddenpropsymderef only in case if property has ppo_overrides flag
  - save/load parameters symtable only in case if property has ppo_parameters flag and has not ppo_overrides flag
  - in case if property is overrides and has parameters copy original symtable

feeff56099 We need to flag specializations of record-/objectdef once we have generated their methods otherwise an interesting situation might occur:
The classes in "fgl.pas" implement an enumerator in the generic class "TFPGListEnumerator" and "specialize" that inside themselves. If we now specialize one of the generic classes (e.g. "TFPGList") the "TFPGListEnumerator" is really specialized as well. That means a def is added to the global symtable (the local one in case of a program or library file). If we now use the enumerator class in the same file (e.g. by using a "for ... in", which has a temporary variable of that type) then the methods of the enumerator are specialized again (the def itself is not). To avoid this (and time consuming searches for existing method specializations) we flag the specialized def as "done" once we're finished.

symconst.pas
  * add a new flag "df_methods_specialized" to the "tdefoption" enumeration

psub.pas, process_abstractrecorddef
  * check the def for the "df_methods_specialized" flag and continue only if that is not set
  * set the "df_methods_specialized" flag before leaving the function

90278ec755 Allow generics to be overloaded by variables.
* symconst.pas:
   add an entry for the generic dummy symbol to the symbol options enumeration
* pgenutil.pas:
   - extend "generate_specialization" by the possibility to pass a symbol name instead of a def
   - if "symname" is given that is used; otherwise "genericdef" or "tt" is used
* pexpr.pas:
   - in case of "<" we are trying to receive a generic dummy symbol from the left node (new function "getgenericsym")
   - it's name is then passed to "generate_specialization" which in turn fills genericdef
   - adjust call to "generate_specialization"
* pdecl.pas:
   - we can now check for "sp_generic_dummy instead of "not sp_generic_para" to check whether we've found the dummy symbol of a previous generic declaration
   - if a new dummy symbol is created we need to include "sp_generic_dummy"
   - if we've found a non-generic symbol with the same name we need to include the "sp_generic_dummy" flag as well
* symtable.pas
   - add a new function "searchsym_with_symoption" that more or less works the same as "searchsym", but only returns successfully if the found symbol contains the given flag
   - "searchsym_with_symoption" and "searchsym" are based on the same function "maybe_searchsym_with_symoption" which is the extended implementation of "searchsym" (note: object symtables are not yet searched if a symoption is to be looked for)
   - add a function "handle_generic_dummysym" which can be used to hide the undefineddef symbol in a symtable
   - correctly handle generic dummy symbols in case of variables in "tstaticsymtable.checkduplicate"

005795495d merge r17552 from cpstrnew branch by inoussa:
*In normal procedure "var" and "out" RawByteString parameters does not accept other string types. Procedures with
"compilerproc" directive or the newly added "rtlproc" directive accept that. Please note that it is up to the
procedure coder to ensure the correctness of the code page in that case. The new directive is needed to handle 
the RTL procedures/functions that are not marked as "compilerproc" such as "UniqueString", "Insert" and "Delete".

*Correct "fpc_ansistr_concat" to handle code page correctly.

*Default "ansitring" type is now created with code page set to "0" instead of "65535". Before that change it was 
impossible to distinguish a "RawByteString" with the default "ansistring". At runtime "ansistring" variable'code
page is set to DefaultSystemCodePage

*UniqueString flavor of "SetLength" has been updated to release memory when shrinked to at least 50%, like ansitring
does.

ee75bfaaf4 * change non-virtual instance methods to "virtual; final;" methods on the
JVM target, because that's the only way to guarantee their semantics on
    that platform (see comments in pdecobj)
  * allow starting new inheritance trees (which is the same as adding a new
    non-virtual method as of this revision) on the JVM target in case the
    parameters of the new routine match the old one, but the complete mangled
    name does not (because then the JVM won't consider them to be the same
    either -> Pascal semantics are matched)

13b0ac91d9 + generate java.lang.Enum descendant classes for Pascal enum types
o these classes get an "enum" flag in the class files
   o these classes get a class field (whose type is that same enum
     class) per enum in the type, which also gets the "enum" flag
   o those class fields are initialised in the class constructor
     with the name of the enum and their order in the declaration
   o if the enum has jumps in FPC (lowest value is not 0, or not
     all values are contiguous), then we add an extra field
     to hold the FPC ordinal value of the enum
   o these classes get a class field valled $VALUES that contains
     a reference to the aforementioned class fields in order of
     declaration (= ordinal->instance mapping, JDK-mandated)
   o apart from the JDK-mandated instance methods (values, valueOf),
     also add FPCOrdinal (returns FPC ordinal value; same as order
     of declaration in case of no jumps) instance method and FPCValueOf
     (returns enum corresponding to FPC ordinal value) static class
     method
   o the mapping between FPC ordinals and enum instances in case of
     jumps is stored in a hashmap whose size is the next prime number
     greater or equal than the number of enum elements
   o moved several extra JDK types to the system unit for the enum
     support, and for future boxing and Java set support
   o several new synthetic method identifiers to generate the enum class
     methods/constructor/class constructor
   o enums with jumps are ordered by FPC ordinal value in the JVM
     $VALUES array so that the java.lang.Enum.doCompare() method
     will properly compare them

40e0b4677a + support for (only named, for now) records in the JVM target:
implemented via classes, all descending from system.FpcBaseRecordType
    (records are also considered to be "related" to system.FpcBaseRecordType
     on the JVM target)
  * several routines are auto-generated for all record-classes: apart
    from a default constructor (if there is none), also clone (which
    returns a new instance containing a deep copy of the current
    instance) and deepCopy (which copies all fields of one instance
    into another one)
   o added new field "synthetickind" to tprocdef that indicates what
     kind of synthetically generated method it is (if any), and
     mark such methods also as "synthetic" in the JVM assembler code
   o split off the JVM-specific parser code (e.g., to add default
     constructors) into pjvm.pas

      errors in the injected strings
    o in case of the actual application (adding overriding constructors):
      the parameters may be of types not visible in the current unit to
      newly written code -> can't just use the scanner...

37b5c061e3 + support for "final" fields in *external* (Java and other) classes, enabled
via {$modeswitch finalfields} (on by default on the JVM target). The
    meaning is the same as in Java: a final (class) field can only be set
    in a (class) constructor of the class it's defined in, and can only be
    written once there (and *must* be set there). They are currently only
    supported for external classes since that basically turns them into
    constants, since for non-external classes we need full dataflow analysis
  o refactored pdecobj.parse_object_members() a bit in the process to reduce
    the amount of repetition (which would have been further increased for
    the support for final fields)
  o made error message about "wrong use of absolute" for fields etc generic,
    so it gives a proper error depending on which token was used (it had
    to be made generic for "final" support, but already was used for other
    things that were wrongly reported as "absolute" misusages)

   o allow specifying an "import_dll" for external Java classes, which can
     be used to specify the Java package name (like the dll for cppclass)
   o take the package name into account when mangling the Java class name
   o several messages that were specific to Objective-Pascal classes have
     been generalised because they also apply to Java classes, same for
     several compiler function names
   o disabled some proccall directives for Java, but more needs to happen
     (Java methods are always either instance-virtual or class-static)

80100734c5 *type symbol overloads are only allowed in mode Delphi
*a check for overloads with the same count of arguments is not yet in place
*in non-Delphi modes overloads need to be checked for non-generics as well, e.g. "TTest<T>" is already defined and now a "TTest" is declared
*when a generic is encountered and the symbol does not yet exist, a new symbol with an undefineddef is added and the generic def is added as an overload; if the symbol already exists, the generic is just added
*if a non-generic is parsed and the symbol is already defined (but the typedef is still an undefineddef) then the typedef is updated
*the symtable tree (up to the unit symtable (global or local)) gets the "sto_has_generic" flag which will be used when searching generics with the same name, but different parameter counts in different units

broken, because the generic defs are not yet searched/found
