The testcase runs 100% fine under Linux Debian 9 - 64 bit. Even 64 bit
constructors work now. This is very good news!
A long time ago, FPC rev. 26683 broke pascalscript's 64 bit support
for constructors so I didn't expect that to work. A while ago I was
trying to fix it, after three days of looking I found the responsible
version and lines of code and then had a discussion with Carlo Kok
about it: https://github.com/remobjects/pascalscript/issues/154
The code that needed fixing was written in assembler (pascalscripts
x64.inc) which I don't understand, and Carlo didn't say he fixed it.
So I'm curious who did, you or Carlo?
I submitted a pull request for the 64bit constructor earlier today.
Actually the asm code didn't need changes. The 2 issues where
- which register to use for what data. Compile an fpc example with -al
and see what fpc uses. Then luckily all necessary changes existed in the
32 bit include, so I could copy it with minor changes.
- a wrong typecast of a 64 bit address to 32 bit.
I didnt know when this was changed in fpc, so the fix now breaks it for
older fpc < 3.0
