I am guessing, that there must be something in initialization
sections of units (SysUtils and Classes), which cause that some code
is included, right?
Can I somehow to avoid this grow of size (for example I need from
Classes only TFPList)?
Not in an easy way at the moment, I don't expect it to change anytime
soon.
The problem is probably the streaming system that the compiler can't
easily determine if it is used runtime. This also has resourcestrings
as errors, uses typeinfo etc etc. I also see interface related
support probably because tcomponent also implements interfaces.
What I can say is, that in initialization sections are touched:
SysUtils: WidestringManager, Exceptions, FormatSettings
Classes: TCriticalSection, TList, TThreadList, TComponent
(IUnknown,IDispatch, RegisterInitComponentHandler() -> var
InitHandlerList), Interface (var GlobalNameSpace: IReadWriteSync)
So we see that classes like TComponent and also interfaces are touched,
but they are used only in conjuction with initilizing some global
variables like InitHandlerList, GlobalNameSpace.
But these variables are never used in my library. Only again in
finalization sections of above mentioned units.
Does it means, that smart-linking can not remove this code due to usage
of this global variables in finalization section (resp. initialization
sections)?
Probably it is too hard task for linker to determine which code is realy
not needed ... WPO in this regard can not help?
