Vikram,
I didn't know that EQUIVALENCE is the only unsupported major Fortran
feature, as this bug says. Can you give me an update on the status of
the Fortran front-end and what the near-term goals are?
Ok. I was going to post something soon after 2.2 release, but let's do
it now.
LLVM 2.2 will contain (as a part of llvm-gcc 4.2) a port of gfortran
compiler to the LLVM rails. This port is mainly for trying/testing and
reporting bugs against it.
Currently I'm seeing 1-2 fails in polyhedron suite. One of them is due
to lack of EQUIVALENCE support. Another big missed feature is lack of
128bit codegen, but this is not a llvm-gfortran issue only.
Also, it was reported, that there had been 2-3 ICEs in CFP2006, I'm
going to fix them sometimes (or, at least to reduce them to the PRs).
I don't have any personal goals connected with gfortran - I really just
don't know the FORTRAN at all 
If there will be some questions one can surely feel free to ask them,
fill PRs, etc.
