[PATCH] D126465: [RISCV] Use knowledge of VLEN to avoid over-aligning the stack

[Philip Reames via Phabricator via llvm-commits]

I'm a bit confused by this patch.  Where does the VLEN > 32 bit come from?  All I kind find in the spec is that VLEN >= ELEN, and must be a power of 2.  Given ELEN only has to be 8, shouldn't the smallest VLEN also be 8?  This seems like an utterly useless configuration, but the spec seems to allow it?
