aarch64 does not run
I downloaded the aarch64 binaries to a ubuntu machine:
wink@ssi-primary:~$ uname -a
Linux ssi-primary 3.5.0-21-generic #32-Ubuntu SMP Tue Dec 11 18:51:59 UTC
2012 x86_64 x86_64 x86_64 GNU/Linux
And when I try to run gcc-4.7.3:
wink@ssi-primary:~$ ls -al
~/aarch64-toolchain/gcc-linaro-aarch64-linux-gnu-4.7+bzr115029-20121015+bzr2506_linux/bin/aarch64-linux-gnu-gcc-4.7.3

I get a file not found:

I must have done something real stupid, any help appreciated.

>* Start analysis on jump threading in GCC. What kind of analysis are you going to do? I have some helpful hints dealing with the jump threading in VRP. Really DOM should be removed fully as most if not all the other optimizers already do its job. Also you should do this analysis on the GCC list right away because Jeff Law and Steven Bosscher can help you understand why things are done currently the way they are done. You will gain more optimizations improving VRP rather than improving jump threading in general.
