Can you try something for me? Can you set BOOT_CFLAGS to '-fno-strict-aliasing -O2 -g' and try
bootstrapping again as on PPC this is the way I was able to bootstrap tree-ssa (it is a known
problem)?

Nope, some thing.
I tried
make clean
make BOOT_CFLAGS="-fno-strict-aliasing -O2 -g" bootstrap
and got the same results as before.
My installed compiler is gcc 3.2.3 (Debian).

There has been a new merge from the trunk yesterday. Can you try with updated
sources?
(Yeah I know we're asking a lot of you, but then, SPARC machines are not as
popular as they used to be... :)
If that does not work, have you tried bootstrapping the trunk? You didn't tell
if that does work for you, and if it does not, then this doesn't have to be a
tree-ssa problem.
Thanks!

Mainline bootstraps without trouble, tree-ssa doesn't.

There have been some changes lately that might have fixed your problems, Can you try
bootstrapping again?

The bootstrap failed again. However, the tree-ssa branch did bootstrap on
hppa.

Pinski, James,
any news on this, does the branch bootstrap for you now? There have again
been many many changes^Himprovements on the branch since this was last
tested&reconfirmed.

tree-ssa bootstrapped for me today. I have no clue what fixed it.
This time I only enabled c, but otherwise things are the same.
