Re: Compiling 64 bit emacs for Power4/Aix-5.2

[Larry Hunter]

The following message is a courtesy copy of an article
that has been posted to gnu.emacs.bug as well.


Next steps in the saga of trying to compile a 64 bit emacs for
power4/AIX. I defined an m/ibmpower4.h file with the following:

#define BITS_PER_LONG           64
#define BITS_PER_EMACS_INT      64
#define NO_ARG_ARRAY
#define NO_UNION_TYPE
#define EMACS_INT               long
#define EMACS_UINT              unsigned long
#define SPECIAL_EMACS_INT
#define VALBITS         60
#define PNTR_COMPARISON_TYPE unsigned long
#define XPNTR(a) XUINT (a)

I don't yet have an unexec working, but doing CANNOT_DUMP, I do get as
far as a temacs that can do loadup. However, as soon as I start the
temacs, I get

"Warning: past acceptable memory limits"

So it appears that I am missing some declaration about how large
the address space really is, or something like that.  

Any ideas?
