2372a06926 * fix #39740: consider a conversion of a procedure or procedure variable to a function reference as a bit more expensive than otherwise 
+ added test

Sven/Sarah Barth
492754ecca * the check for nested procvars is now done during the conversion in capturer_add_procvar_or_proc so loosen the check in proc_to_funcref_equal_internal 2022-05-31 22:50:14 +02:00
Sven/Sarah Barth
4361e36ce0 * make proc_to_funcref_conv publicly available 2022-05-31 22:50:14 +02:00

5a680f0148 * fix #39745: the conversion from ordinals to pointer types in mode Delphi is not allowed for a void type (happens when using a typecast to convert a method without parameters to a function reference) 
+ added test

2be8f01efe * implement assignment of anonymous functions to procedure or method variables if they either capture nothing or (in case of method variables) at most the Self variable 2022-05-26 21:43:01 +02:00
Sven/Sarah Barth
17514ed5c0 * allow to ignore Self parameters; for this the parameter skipping needs to be repeated to correctly catch all cases 2022-05-26 21:43:01 +02:00

2808873d1b * Reworked the optimization of unused $parentfp for nested routines. 
- Do not remove the $parentfp parameter as was done in the previous optimization approach. Instead when $parentfp is unused to the following:
      - On the caller side: Omit passing the value for $parentfp for targets where tcgcallparanode.push_zero_sized_value_para=false (classic CPU targets). 
          Pass 0/nil as $parentfp for targets where tcgcallparanode.push_zero_sized_value_para=true;
      - On the callee side: Prevent allocation of registers/resources for $parentfp.
  - When possible keep $parentfp in a register.
  - Set the pio_nested_access flag in tprocinfo.set_needs_parentfp() to properly handle deep nesting levels;

44bfa98a30 * fix for Mantis #35955: when the element of an array constructer requires an operator for conversion we don't let the caller of compare_defs_ext know that, instead we simply say that some conversion is required and let the typecheck handler deal with the element wise conversion

1da43f67d4 * (non-ancient) Delphi versions that accept explicit ordinal -> floating 
point typecasts behave the same as FPC (convert the value) rather than
    as Turbo Pascal (reinterpret the bit pattern) (mantis #35886)

c038e4c3f2 * relaxation of r42272: again only show warnings rather than errors for 
out-of-range constants, because of the comments mentioned in #35753
    (except for enums, as apparently Delphi does the same)
  * added range check warnings about explicit type casts that throw away
    bits (e.g. byte($fff)), without giving warnings for most common cases
    (like cardinal(-1))
  * fixed masking/sign exting constant array indices (must be based on index
    range type size/signedness rather than on array size/"signedness")

{$modeswitch arraytodynarray} is active (mantis #35576)

50ab607676 + customint torddef type to create arbitraty bit-width integers

9bd931e931 * make "formal const/var" parameters the least preferred conversion 
(mantis #32179)
  - removed code to handle conversion to formaldef parameters that are not by
    reference (so the default conversion preference is kept)
