A couple of days ago I fixed an error in svn trunk for ARMEL that caused
the stack to become temporarily unbalanced after performing syscalls
with 5 or more parameters (the bug is still there for OABI, but I can't
fix that because I don't have access to an OABI machine).
I have an ARM board with an OABI kernel running (because I wasn't yet
eager enough to test how FPC behaves with an EABI uclibc ^^).
If you can tell me what I need to look out for I might be able to help
you there.
I now looked at the current actual code for OABI syscalls and it seems
that the problem does not happen there. For OABI, the quick-exit trick
is only used in a single stackframe-less function, and that's fine.
Sorry for the false alarm.
sorry for jumping in. I have a complex OABI application based on fpc
2.2.x and I um using a syscall with 5 parameters heavily. I had no
problems so far, the applications runs stable. I am worried now, if I
should adapt the actual OABI code to the old RTL?
Regards, Bernd.
