38058505ba * Changed linking infrastructure to look like assembler one: 
* Changed direct references to linker classes in TSystemInfo records to enumerated ids.
  * RegisterExtennalLinker and RegisterInternalLinker procedures replaced by single RegisterLinker procedure and moved to link.pas.
  - TAbstractLinker is no longer necessary, removed.

This change allows to register linker once per id, rather than once per target, and also allows TSystemInfo records to be read-only.

eec8129738 * TInternalLinker.Load_ReadStaticLibrary: exit if error has occurred while opening a static library or dynamic object, continuing can cause other errors/crashes in this case. 
* t_linux.pas: use sysrootpath when specifying dynamic interpreter (for cross-linking).

d11ec8ac47 - Reverted r25269 and commented out r25261. The former one is wrong because it changes unit initialization order. The latter one causes RTL build failures on some targets, needs testing and likely RTL/makefiles patching.

e1ddd914ac * Do not implicitly load Variants unit when compiling units. Doing so is mostly waste of time, and introduces unwanted build dependencies. It is enough to set uf_uses_variants flag for units, and examine these flags when compiling program/library. Resolves #24880.

d8c84706dd * use Tai_symbol.Create_global() when emitting a global symbol for an 
abstract method wrapper (tai_symbol.create() currently overrides the
    symbol type from global to local; will fix in next commit)
  * only generate global abstract method wrappers for the class in which
    the abstract method is declared to prevent duplicate symbol errors

fe4cac96be + added overloads to tai_const.Createname and Create_type_name, which take a Tasmsymtype parameter; to be used for declaring external symbols which reside in the data segment with AT_DATA, which is necessary for i8086 medium and compact memory models (where code and data pointers are of different size)

b81f746e05 Inline Length(DynamicArray) 
Up until now a helperfunction was called at runtime. This change inlines
the whole code in the same way Length(AnsiString) works. As dynamic
arrays do not record their length but their highest index, an additional
"OP_ADD" is this case.

5c4abfa75a + Implemented saving/restoring registers using PUSH/POP instructions on i386 targets with non-fixed stack. Provides some advantage in code size (e.g. the compiler becomes about 20KBytes smaller). 
* This should be applicable to i8086 targets as well (but needs testing), by copying changes from i386/cgcpu.pas to i8086/cgcpu.pas and removing "$ifdef i386" lines in cgx86.pas.

1ce93f7430 * when automatically generating an overriding getter/setter method (because 
a property in a child class has a higher visibility than the getter/
    setter), ensure that we call the inherited method and not the method
    itself (causing a stack overflow due to infinite recursion)
