For the moment my plugin's 'view' is limited to a single function but
that should be something to improve.

documentation and help next week.
Thanks for your interest!

Hello,
sorry to answer that late (I didn't saw your mail in my mailbox + I
was preparing me for RMLL/Libre software meeting).
Your solution looks to be a nice one, I am goiing to try it and I will
post the result of my experiment. I was not aware of that hook.
Thanks!

I have looked at cp/mangle.c, which has some interesting function, for
exemple giving the mangle named from the corresponding tree, but in this
case, how can I get the tree?
If you have any idea, thanks!

I have written a new page on the wiki

What would be the better way to patch this?

Hello,
I would like to announce that I have been able to compile GCC while

It creates a pass after SSA and wo
