I made a patch which fixes regressions on ARM platforms with disabled

unaligned access to vector are allowed. This leads to spurious vect.exp

yes -- I am thinking about this and other better hash functions.
Changing it to 64bit will cause profile format change and increase in
profile data size.

Btw, what will be the way to plug in an alternative hash function?
That is, there doesn't seem to be a separation of interface
and implementation in your patch (like with a template or a
base-class
you inherit from).
It's worth noting that merely changing the hash function from crc32 to
something that's 64 bit long is enough to make sure collisions does
not happen. Maybe it's worth the trouble?

I don't think existing profile data matter.
For perfect fresh profile, using external id has the chance of
collision. I have tested with a C++ symbol file with about 750k unique
symbol names, using crc32 based id yields 71 collisions --- the rate
is ~0.009%.
init_node_map will resolve
So there will be at most one hash implementation?
One per binary I expect. Modern hash functions are pretty good,
so it's unlikely that someone needs to come up with special
purpose hashes.
I found Bob Jenkins' spooky is rather good for this case (very
large incremential keys), but it is only
Why didn't you replace the tree.c uses BTW?
Patches were already quite big, but I'll add it.
Actually I handled them all in tree.c. Did you
mean something else?
I didn't convert all of tree-ssa-* and dwarf* so far,
and a few other places. This can be done step by step.
