Thanks, I knew this but for an optimization patch, we
need to prove that it actually improves (or doesn't degrade)
code for (N >= 5) targets. This IMHO requires significant effort.
But since there is interest on this, I can do simulator
test with latest version of the patch, but not in a position to
fix problems except sh-elf.

This would probably have to be tested on tree-ssa branch now, right?
Let me check what additional problems arise.

Yes you can: <URL:http://gcc.gnu.org/simtest-howto.html> tells
you how.
Certainly many of the target listed fail to build, but you
should be able to find five even without including your host
computer. Last I checked, arm-elf, m32r-elf, mips-elf,
mn10300-elf, v850-elf and sh-elf worked (perhaps others do, but
I don't test all the listed ones). Oh, you can test using MMIX
too; put Knuth's simulator named "mmix", linked from
<URL:http://www-cs-faculty.stanford.edu/~knuth/mmix-news.html>
somewhere in your PATH, use --target_board=mmixware-sim.

This was the last post.

Do let me know if you are interesred to use this. This has
not been checked in the mainline. For patches like this
to go into mainline, they should be tested for atleast 5 gcc
targets. I couldn't do that. But I can help, if you are
interested.
Best Regards,
Naveen Sharma.

They are first come first served. The first one spilled gets the first
available stack slot, etc.
There have been some proposals to sort them, offhand I don't know if
there are patches available anywhere for this.

Are the register spilled values laid out in memory following
some particular scheme or randomly?
