* Remove some instructions that existed to provide aliases to the assembler. ↵Craig Topper2013-10-081-1/+1
| | | | | | Can be done with InstAlias instead. Unfortunately, this was causing printer to use 'vmovq' or 'vmovd' based on what was parsed. To cleanup the inconsistencies convert all 'vmovd' with 64-bit registers to 'vmovq', but provide an alias so that 'vmovd' will still parse. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192171 91177308-0d34-0410-b5e6-96231b3b80d8
* X86: Do splat promotion later, so the optimizer can chew on it first.Benjamin Kramer2013-01-261-2/+2
| | | | | | | | | | | | This catches many cases where we can emit a more efficient shuffle for a specific mask or when the mask contains undefs. Once the splat is lowered to unpacks we can't do that anymore. There is a possibility of moving the promotion after pshufb matching, but I'm not sure if pshufb with a mask loaded from memory is faster than 3 shuffles, so I avoided that for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173569 91177308-0d34-0410-b5e6-96231b3b80d8

* Now that we have a canonical way to handle 256-bit splats:Bruno Cardoso Lopes2011-08-171-5/+5
| | | | | | | | | vinsertf128 $1 + vpermilps $0, remove the old code that used to first do the splat in a 128-bit vector and then insert it into a larger one. This is better because the handling code gets simpler and also makes a better room for the upcoming vbroadcast! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137807 91177308-0d34-0410-b5e6-96231b3b80d8
