fixed patch
Ah, obvious oversight - I forgot to replace the realpart parameter in the
vector of parameters.
--- Comment #9 from rguenth at gcc dot gnu dot org 2010-01-14 14:34 ---
Ugh.
args = copy_list (args);
simple-minded copies all PARM_DECLs in the function - but of course the
actual functions parameter list is not adjusted, this is only a temporary
list used for parameter setup.
So

The first patch appeared to work, resulting in correct ordering, but the second
patch had some issues. It also corrected the original ordering, but introduced
some new incorrect code for handling the args coming

It rightfully returns false - they are two different PARM_DECLs. This is btw
a regression - marked as such.

Can you check -fdump-rtl-all-uid dumps where they start to differ? It seems

Happens in split_complex_args it seems. What this does is changing a
Complex PARM_DECL into a component PARM_DECL and add another for the remaining
component. But it doesn't adjust the function IL nor the

10 bonus points if you make ppc not use that weird feature. I can't see
