[tree-ssa] having problems recently

[Eyal Lebedinsky <eyal at eyal dot emu dot id dot au>]

As of the last week I am having problems. My main use if with mudflap,
where I started getting programs returning wrong results, and running
very slowly. I then rebuilt without mudflap (-O0 -g) and observed the
same problems. So maybe this is not a mudflap problem at all (I saw
no mudflap checkings for a while).

BTW, I am building off cvs.

I then decided to build with '-O3 -g' and this actually failed to
compile. I am attaching a small program that reproduces the failure.
Just change "mf=" to the path of the compiler.
