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.

classes, interfaces, dynamic arrays, ...) as "array of JLObject",
but instead as an array of the actual pointed-to type. The reason
for the previous behaviour was mainly that the JVM threadvar
implementation internally stores all threadvars that are
such double pointer types into an "array of JLObject". Type casting
this array to e.g. an "array of array of byte" causes an exception
even if it only contains "array of byte" instances (since the outer
array type is different). This is now solved by first taking the
element of the array and then typecasting it to the destination
type (so dynarrbyte(arr[0]) instead of pdynarrbyte(arr)^[0]).
The reason for the new (more accurate) behaviour is because the
old one caused type errors in case a double pointer field was
internally created for the nestedfpstruct support (see added
test)

pgenutil.pas, generate_specialization:
* If we are parsing the result type of a function or operator that belongs to a generic (parse_generic is true) we need to accept also "_LT" and "_GT" as for this the "block_type" is NOT set to one of "bt_type", "bt_var_type", "bt_const_type" and only there "_LSHARPBRACKET" and "_RSHARPBRACKET" are returned by the scanner. This is part of the fix for webtbs\tw18567.pp.
* In non—Delphi modes if we encounter a specialization of the currently parsed class/record (using "specialization"!) the given "tt" will be an errordef (because the def of the generic's symbol was not yet set to "current_structdef"). To solve this we check in this case whether the calculated generic name is equal to that of the "current_structdef" and simply return that as specialized def. This fixes test\tgeneric11.pp.
* When searching for the generic symbol search if the generic belongs to a class or record then we need to search for it in the class or record. This fixes webtbs\tw16090.pp.
ptype.pas
* parse_nested_types: We now return the generic defs for specializations inside generics instead of an undefined def, so we must also parse nested type usages correctly, so that type checks don't fail (undefined defs circumvent them mostly). This fixes webtbs\tw10247.pp.
* single_type: We need to allow _LT as an indication for a Delphi specialization as return types are parsed with block_type not in "bt_type", "bt_var_type", "bt_const_type". This is also a fix a part of the fix for webtbs\tw18567.pp.
* read_named_type, expr_type:
Fixes for test\tgeneric17.pp and test\tgeneric22.pp:
(a) In non-Delphi modes we might encounter usages of the generic dummy symbol inside the generic class belonging to it. This is basically a specialization, but as the reference from the dummy symbol to the "current_structdef" is not yet established (this is done after "read_named_type" in "types_dec" returns) we need to use other ways to check for the valid use of the dummy symbol (basically we check whether the name of the dummy symbol and the name of the current_structdef without the type count match)
(b) For specializations we can check whether the genericdef of the currently parsed structdef (the specialization) is the same as the typedef of the encountered dummy symbol.
pexpr.pas, factor, factor_read_id:
Fixes for test\tgeneric17.pp and test\tgeneric22.pp:
To allow the mentioned fixes in ptype for the same tests to be usable at all we must not return an "identifier not found" error if we encounter such a valid use of a generic dummy symbol.

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.

Extend ttypenode by a reference to the type symbol.

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.

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.

* add a new function "sym_is_owned_by" which is similar to "is_owned_by", but takes a symbol and a symtable as parameter; the owner chain of the symtable is checked until a non-object- and non-record-symtable is reached
ptype.pas:
* extend "id_type", so that the symbol and the symtable that belongs to the returned def is returned as well
* this is needed to check inside "single_type" whether a def that is a generic was specialized inside another generic, because in that case the genericdef is returned by "generate_specialization" and not a new specialized def, but the corresponding type symbol (which is different from "hdef.typesym") belongs to the class itself; I need to admit that this solution isn't very clean and one could try to circumvent some of the checks, so I need to find a better detection for such a case (concrete example: the enumerator specialization inside the classes of "fgl.pas")
* in "read_named_type.expr_type" the check for "df_generic" is extended analogous to the previous change, but instead of relying on the symbol it uses the def. This is needed so that types like method pointers that are defined inside the current generic are not disallowed as they contain the "df_generic" flag as well; like the previous change this change isn't clean either and maybe it's better to remove the inclusion of the "df_generic" flag from everything except records and "objects" inside records/"objects" again. Such a solution will "only" reduce the problem to records and "objects" though...
pgenutil.pas:
* only add a new undefined def if we're not parsing the parent class or interfaces ("parse_class_parent" is true), otherwise the InternalError regarding the "equal count of defs" will trigger
* there are now two cases where we need to return a generic def instead of a undefined one when we're parsing a generic:
a) we have the previously mentioned case that "parse_class_parent" is true
b) an undefined def was added, but we need to return a generic def, so that checks can be passed
* use the correct variable when building the generic name, otherwise we get errors like "identifier '$1' not found"
* don't push the symtable if we're currently parsing the list of interfaces or the parent class, because then e.g. a generic interface will be included in the symtable of the implementing class which isn't what we want; the current solution is not clean though, so this needs to be investigated more
* Note: In the current state of "generate_specialization" the function could be simplyfied a bit more; this will be done when the implementation is satisfactory enough

* 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"

Switching from overloaded type symbol to unique symbol per generic.
Reasons for the "unique symbol" approach:
- no special search operations for cross unit search needed (which is supported by Delphi) => less performance impact
- no special care needed to really find the correct generic => less increase of parser complexity
Currently all generic tests except tgeneric29.pp compile and inline specializations work as well.
The changes in detail:
* pdecl.pas/types_dec:
- The variables used to hold the final name of the symbol are now prefixed with "gen". In case of non-generics the prefixed ones are equal to the non-prefixed ones (e.g. orgtypename=genorgtypename). In case of a generic symbol the "gen"-variants contain the type parameter count suffix (e.g. '$1' in case of 'TTest<T>') as well.
- The unmodified pattern is used to insert and detect a dummy symbol with that name, so that type declarations and - more important - inline specializations can find that symbol.
- In non-Delphi modes this symbol is also used to detect whether we have a type redefinition which is not allowed currently; its typedef points to the generic def.
- In mode Delphi the def of that dummy symbol (which contains an undefineddef) is modified when a corresponding non-generic type is parsed, so that it contains the def of the real type.
* pdecsub.pas/parse_proc_head
- consume_generic_type_parameter now only parses the type parameters and picks the generic with the correct amount of parameters. The verification of the order and names of the parameters needs to be added again.
- it also does not use "def" anymore, but it sets "srsym"
- in parse_proc_head the symbol (srsym) is only searched if the symbol isn't assigned already; in case of a generic in mode FPC it will find the dummy symbol that points to the generic def
* pexpr.pas
- in factor_read_id there are three cases to handle:
+ the symbol is not assigned => error
+ a possible generic symbol (either an undefined def or the non-generic variant) => no error and no hints
+ a non-generic symbol => hints
Point 1 is handled correctly, point 2 and 3 aren't currently and also they might be needed to be moved somewhere else
- sub_expr:
+ a node can be a tloadvmtaddrnode as well if the non-generic variant of a generic symbol is a class
+ we can only check afterwards whether the specialization was successful
* pgenutil.pas/generate_specialization
using the count of the parsed types the correct symbol can be found easily

Implement support for nested non-generic types inside generic types. This is mostly for records, classes and objects ("structures") as those didn't work at all, but the others (arrays, procvars) weren't done cleanly either.
pobjdec.pas (object_dec) / ptype.pas (record_dec, array_dec, procvar_dec):
- enable "parse_generic" if a nested type is parsed and we're already inside a generic (this prevents code to be generated for the nested type's methods)
- set the "df_specialization" flag so that the code for generating the methods (and thus resolving the forwards declarations) is called for this symbol
pexpr.pas:
add "post_comp_expr_gendef" which basically calls "handle_factor_typenode" and "postfixoperators" as those aren't exported from the unit themselves
ptype.pas, read_named_type.expr_type:
- use "post_comp_expr_gendef" to parse the use of nested types (e.g. "var t: TTest<T>.TTestSub")
psub.pas, specialize_objectdefs:
implement the generation of the method bodies for nested structures (resolves the forward declarations)
pdecl.pas, types_dec:
when we encounter a nested structure inside a specialization of a structure, we need to find the corresponding generic definition so that the generic can be correctly parsed later on.

------------------------------------------------------------------------
git-svn-id: trunk@19763 -
pexpr.pas: Changes in postfixoperators and the base of handle_factor_typenode not yet incorporated (the code from trunk was simply commented for now)
git-svn-id: branches/svenbarth/generics@19676 -
The changes regarding pretty names for generics and token buffer endianess were integrated into my changes. Not every call to generate_specialization is fixed though, so compilation will fail.
git-svn-id: branches/svenbarth/generics@19674 -
using the type name of the interface/protcol/category (they are not
entities themselves on which you can invoke those methods,
mantis #20661)
git-svn-id: trunk@19651 -
implicit pointer types into the nestedfpstruct, so that the original
parameter is properly changed when updated from inside nested routines
git-svn-id: branches/jvmbackend@19645 -
+ -CTcompactintarrayinit command line option to change the code generation
for typed array of some kind of integer-type initialization so that it
takes up less space in the bytecode (because the bytecode for all
routines, including the class initialization code that contains the
typed constant init code, is limited 64kb, large array or multiple
array constants could fairly easily bump into that limit)
git-svn-id: branches/jvmbackend@19638 -
set the external name of the underlying class type to the internal name
instead of to an (invalid) empty string
git-svn-id: branches/jvmbackend@19555 -
+ test from bug report
- remove $A+ from jedi include header: $A+ makes no sense for api headers, the records should be layouted with $packrecords c, second part to resolve#20525
git-svn-id: trunk@19533 -
- don't pass CP_NONE encoding to internal functions. They handled it as 0 encoding. This will optimize the generated code a bit.
- convert all king of string/char/pchar constants to local ansistring def if they needs to be passed to rawbytestring type. They should not get a CP_NONE codepage (delphi compatible)
- don't convert left and right arguments of string concatenation to ansistring type if they are already ansistrings but with different codepage - RTL already handles different codepages in concat routine
- fix resultdef for ansistring concatenations inside assignments - return def of left assignment operand if it is already ansistring - this reduces amount of unneeded condepage conversions since concat functions can return result in any desired codepage
rtl: remove CP_NONE comparisions from most of RTL functions, replace 0 constant with CP_ACP
tests: add test to check various conversions to RawByteString type
git-svn-id: trunk@19519 -
- 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
git-svn-id: trunk@19510 -
implementation (Delphi-compatible in case multiple overloads exist in
the current unit, and in other cases avoids compiler crashes in case
of circular implementation dependencies)
* ignore other symbol options (deprecated, legacy, platform, ...) as far as
the interface crc is concerned to avoid trouble in case they appear in the
implementation but not in the interface (to prevent compiler crashes)

* ToLower is functional for all characters including those outside of the BMP
* ToUpper is functional for all characters including those outside of the BMP
* Other methods using "const AString : UnicodeString; AIndex : Integer" are
functional for all characters including those outside of the BMP

- add TTagHashSet class descendant of THashSet with an ability to has also a LongWord value together with key
- change TAsmData.ConstPools[] to be an indexed property to properly initialize ConstPool class, remove pool initialization from all other units

* moved console io on embedded systems into a seperate unit, this unit might setup input/output e.g. to be redirected to a serial port
* cleanup of the embedded system unit
