2db4cae7aa nested procvars: support assignments when switch not active 
Support assigning one nested procvar to another even when the nestedprocvars
modeswitch is not active. This can happen when the type was declared in a
different unit that was compiled with this modeswitch, or in internally
generated wrapper code (which uses "pure" objfpc mode)

e746cf96da Overload selection: call procvars if result is compatible with parameter 
Previously we only autmatically called procvars without parameters in TP/Delphi
modes if their result type was equal to the parameter type to which they were
passed. Resolves #39748.

b1d9d34665 * only abort due to a missing overload directive if there indeed was any procdef found (due to implicit specializations there might be none), fixes compilation of tests webtbs/tw38310b and webtbs/tw38310c 2022-04-21 18:01:30 +02:00

90844c2027 * fix #35261: apply slightly adjusted changes by Ryan Joseph to implement support for implicit generic function specializations 
The main adjustments were as follows:
  - fixing coding style and identation
  - fixing some typos
  - using a better name for the property in tcallcandidates which holds the symbols created for anonymous parameter values

57d9884d96 * fix for Mantis #38310: ignore procsyms that have no procdefs for checking overloads, or more precisely to stop checking for overloads; these are generic dummy symbols

3597696e98 * fix for Mantis #38145: allow overloading of assignment operators that return ShortStrings with a specific size 
+ added tests

The following rules for using these operator overloads as *implicit* overloads apply (Delphi compatible):
  - if a found assignment operator returns a default ShortString then that is used
  - if only one assignment operator to a String[x] is found then that is used
  - otherwise the assignment is not possible
The explicit assignment checks for an exact match (and falls back for an implicit assignment). This is not entirely Delphi compatible as Delphi seems to favor the first found symbol in that case, but sometimes also not... :/

4682ac269d * Further improvement for r40180: 
An uninitialized function Result of a managed type needs special handling.
    When passing it as a var parameter a warning need to be emitted, since a user
    may expect Result to be empty (nil) by default as it happens with local vars
    of a managed type. But this is not true for Result and may lead to serious issues.

    The only exception is SetLength(Result, ?) for a string Result. A user always
    expects undefined contents of the string after calling SetLength(). In such
    case a hint need to be emitted.
+ Tests for this.
