This is not the result you are looking for: The result of "postfixoperators" is only set to true if either "again" was "true" once or the node was changed to an errornode. So using the result for deciding whether we overwrite the def or not is incorrect. So just call "postfixoperators" and process the returned node accordingly.

* fpc_help_constructor: call platform-optimized version of FillChar directly instead of going through generic overloaded version.
* don't compile software multiplication routines if not necessary (the interface part already has similar $ifdef around)
* fpc_shortstr_append_shortstr: use sizeint instead of integer (the latter is 16-bit, produces less efficient code on most platforms)
git-svn-id: trunk@19727 -
* Adjust a comment.
* Add an additional check for the owning symtable of the dummy symbol and the current_structdef just to be on the save side (it's not needed inside specializations)

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.
git-svn-id: branches/svenbarth/generics@19719 -
* Some Delphi-compatible changes:
* For floating point underflow condition, raise EUnderflow, not EOverflow.
* For unknown codes, raise EInOutError, not Exception.
* Added entries for EZeroDivide and EStackOverflow (actually raising EZeroDivide on floating-point division by zero requires further changes to System because currently both integer and float division by zero is mapped to the same code 200).
