Hello guys,

Im recently tinkering with PARISC machines which I've left.
I've got two of them, one with HPUX 11iv1 (old, I know) and one with Linux.

According to the libffi main page, HPPA is indeed supported (not on 
Linux, but this is outdated?).
I've written a simple test code, in order to sanity check libffi's basic 
functionality.

This code is working fine on i386 and amd64.. just for reference.
My main goal is getting libffi working (eg. ported) to HPUX LP64... I've 
began consulting the proper documents from HP and learning a bit of 
PARISC asm.. but Im still at the beginning.

Right now, I wanted to confirm the functionality which is obviously 
existing...
The first try I've given is on the C8k with Gentoo Linux:

Linux hppa 4.9.49-gentoo-r1-hppa64 #4 SMP Fri Jun 8 19:33:13 CEST 2018 
parisc64 PA8900 (Shortfin) 9000/785/C8000 GNU/Linux

therion@hppa ~ $ qlist -Iv libffi
dev-libs/libffi-3.2.1
virtual/libffi-3.0.13-r1

So far so good... I've this installation now for a while...
The thing is that my test code is failing with 64bit signed integers.

Im hoping that any of you may look into it, or can lend me a hand - was 
this ever supposed to work? Is it actually working?
My test code is buggy? If so which part? :)

Since it's just test I'll attach my code here.

Output:
