Richard, did you look at rs6000_hash_constant and toc_hash_eq in rs6000.c?
No.
I think they might need updating.
They do. There are some constants that need changing. Thanks.
For instance, there's the comment
/* Gotcha: One of these const_doubles will be in memory.
The other may be on the constant-pool chain.
So rtx_equal_p will think they are different... */
and I'm not sure all the related code is still correct.
That comment never made much sense since rtx_equal_p only considered
two CONST_DOUBLEs the same if they are at the same address for quite
a while (at least as long as GCC 2.8.1 and probably forever).
