how to obtain SSA form

[Andrea Callia D'Iddio]

hi all,

I'm trying to make some optimizations in gcc, and I need to manipulate
control flow graph when code is translated in SSA form. I wrote
optimization code, but I noticed that when my code is executed the
code isn't in SSA form, it's only in GIMPLE form. How can I obtain the
SSA form to apply my code? Is there an option from command line, or
any flag to be setted?

Thanks to all

Andrea
