Re: [Tinycc-devel] x86_64 ABI: mixed structs

[Pip Cet]

Thanks for testing! You're right on both counts; I should have said
that I haven't been able to test PE and the other architectures, and I
didn't know about --enable-cross—that's a really handy option for
testing.

So this version should fix both the issues you report and the 7
doubles - two-double struct - 2 doubles bug. It's not quite ready for
pushing yet, as it currently has O(n^2) behavior in gfunc_call (though
in my defense, so did the original version).

In looking over it, I see that it needs optimization at least (and
possibly fixing) for zero-length structs, too.
