Hi,


If it could helps:

I modified unexaix.c to add this at the top of file:


#define __XCOFF64__ 1


And changed this line:


auxentry.x_sym.x_fcnary.x_fcn.x_lnnoptr += bias;


by


auxentry.x_fcn.x_lnnoptr += bias;


It worked but generated a huge bootstrap-emacs file, 4GB and is generating this error:


[...]

Finding pointers to doc strings...
Finding pointers to doc strings...done
Dumping under the name emacs

exec(): 0509-036 Cannot load program ../src/bootstrap-emacs because of the following errors:
        0509-026 System error: There is not enough memory available now.



Size of the file:


$ ls -l src/bootstrap-emacs

Thank you
