g++ and SSA output

[maniac_ie]

Hey,

Just wondering if g++ supports SSA (single static assignment) output?

I'm using a Mac.

I've checked here
http://developer.apple.com/documentation/Darwin/Reference/ManPages/man1/i686-apple-darwin9-g++-4.0.1.1.html

and it should with the -fdump-tree-ssa switch but it wont output
the .ssa file for me with g++ or gcc

I'm using i686-apple-darwin9-gcc-4.0.1: and i686-apple-darwin9-g+
+-4.0.1:

Anybody any ideas?

Cheers,


Rob
