Subject: [llvm-commits] [PATCH] Optimize trunc store

Hi,

Please review the attached patch. When performing a truncating store, it is sometimes possible to rearrange the data in-register prior to saving to memory.  When we reorder the data in memory we prevent the need to save multiple scalars to memory, making a single regular store.

Thanks,
Nadav
