Subject: bug#6069: INTMASK on 32/64 bit machines
Date: Fri, 30 Apr 2010 22:31:17 -0400	[thread overview]
Message-ID: <AE64E99D-07BE-4A75-A145-E1F386A7C5F6@gmail.com> (raw)
In-Reply-To: <5A5EF5AB-3423-4AB4-A315-FE0E167CCD71@cmu.edu>

I have one post-scriptum.

I just noticed that the large `sxhash' integer was produced on a 64-bit machine with INTMASK 0xffffffff,
but that the read failure occurred with a binary compiled for 32-bit architectures.  In that Emacs, INTMASK is 0x3fffffff.

I think that explains what I'm seeing.

Would it be sensible to make `sxhash' use a lower common denominator for modern machines, such as 0x3fffffff?

Or, should the lower INTMASK be used on 64-bit architectures as well?

It's less than ideal that printed Lisp expressions, especially those in customization files, are not interchangeable between different builds of the same version of Emacs.
