David,
sorry for taking time to get back to it.  I went through the code and see no obvious flaws
except that I am somewhat concerned what happens with local aliases into the anchors.
The problem however does not seem to be caused by it.  I tracked it down to the following
difference:


The code starts to work.  To me both sources should make same binary, but they don't.
Can you make better sense of this than claiming it is an assembler bug?

We output aliases after definitions for functions, but before definitions for thunks.
I am testing patch to change the second order.  I remeber tweaking this order once before
because of problems on solaris.  Lets see if we find order that works for everyone.

Honza,

The AIX assembler is a very simple, single-pass assembler. The order
has a lot of importance because the assembler makes assumptions about
symbols, such as section placement and annotations, if they are
referenced before defined. I notice that your change places the
.lglobl declaration after the .weak declaration.  That may be more
important than placing it after the thunk.

Thanks, David
