This patch reworks the support for dup NEON intrinsics as described in D48439.
Looks OK to me.
But file "test/CodeGen/vld_dup.c" looks weird/empty. I guess you're removing it?
Yep, this patch removes vld_dup.c as it duplicates part of what we have in arm-neon-vld.c. Clicking 'Show File Contents' below the file displays its contents. Thanks for reviewing!
