Hi there.
This is a cross-post (cross-mail ?) to
http://www.lazarus.freepascal.org/index.php/topic,17978.0.html as I
got the hint there that it might be better to ask on the list instead
of in the forum, at least concerning the calling conventions - but
I'll ask the whole lot, anyway; I hope that's ok.
As Vincent pointed out. FPC mailinglist.
Interestingly, when I start debugging
<SomeClass>.Create(aOwner:TComponent)-Type of Constructors, there is
some difference in the Register values, depending on whether the
Constructor was called from "pure" FPC-Code or the Script (at least so
it seems):
o Called from FPC: rcx: 0 (nil), rdx: Class Reference, r8: Value of aOwner
o Called from Script: rcx: Class Reference, rdx: 1 (!?), r8: Value of
aOwner (at least so it seems)
Is there any difference in the calling convention on x64-Systems
between Delphi and Lazarus? I could only find the "standard"
information on Windows x64 calling conventions, without special care
of constructors, if there is any...
You will be able to get an answer about the calling convention fpc uses
(They should be standard)
But you can then check yourself in x64.inc what PascalScript does.
