While I'm surely affected by these "bugs" (C++ with POOMA) and I'm looking
forward to some performance improvements with tree-ssa my experience with
tree-ssa for now is not so good in terms of time and memory consumption.
I'd rather suggest to go for a "quick" 3.5 release with rtlopt and maybe
new-ra merged, because while 3.4 is of superior quality compared to 3.3
for me, it quite seriously regressed in resulting performance. This is
mainly due to the new loop-unroller which is said to be "fixed" on rtlopt
branch.
Tree-ssa needs to go to something like stage 3 (or at least stage 2) for
some time before it looks ready for me.
Just my 2 euro-cents,
Richard.
