Re: Is there any plan for "data propagation from Tree SSA to RTL" to be in GCC mainline?

Wasn't there a GSoC project for this last year? And this year?
It'd be interesting to hear if anything came out of that...
Nothing came of that, unfortunately.
There are two patches, actually. The patch of propagating data
dependences to RTL is ready and working, it wasn't (at that time)
committed just because it was initially completed during stage3. The
patch for propagating alias info wasn't finished within the scope of
this year's GSoC, unfortunately, and I take it more as my fault than a
student's fault, as I failed to help him locally with organizing his work.
We are nevertheless trying to put some work into finishing this patch.
As it is not completed yet, I don't have a subject to discuss. I hope
that before the next stage1 we'll manage to finish the patches and to
unify them before submitting, as the mechanism they use for mapping MEMs
to trees is the same. If we'd not finish the second patch, we'll submit
the first one anyways.
Sorry for not writing this earlier -- I've had a few busy months (mostly
finishing and defending ph.d. thesis :)
