Just an idea: What about serializing TCGPara/TCGParalocation?
The main issue I see with that is that this format changes from time to
time. I'll probably have to change it again to fully support the ppc64le
ABI.
Nevertheless, Florian's proposal seems to me like the optimal solution.
As far as I can see the compiler just needs to simply write a small
block with the needed info in the generated executable. The RTL just
needs to match this.
That this changes from time to time, I consider much less of a problem.
The .ppu files also change regularly, that is just how things are...
As soon as a new platform appears you need to wait for libffi etc;
the correct version needs to be installed and whatnot. I doubt this will
cause less problems.
Considering that we aren't the fastest to implement new platforms I don't think
that this will be
much of a problem.
Actually, FPC had win64 support before gcc/binutils.
Yes, that was one of the glorious exception that I still like to quote
when talking about Free Pascal :D
But other then that we aren't normally the first to implement a platform...
Looking at their site I noticed however that there are a few platforms that we
support that they
don't. For example m68k-amiga, i8086-msdos, arm-wince and some of the more
exotic targets that we
have (GBA, NDS, Wii for example).
So in the end a manager approach as Jonas suggested might be the best approach.
Then we can for now
implement the main platforms using libffi and implement full FPC ones one at a
time.
As long as we have no realiable approach to prevent people to violate the
libffi license, I wouldn't
recommend to do so. Besides this I do not want either that every FPC compiled
binary needs to come
with a libffi license text.
Yes, the license might be the biggest problem here...

Sven
