LLVM backend for 6502
These are really immediate DUPs, and suffer from the same problem with long instructions with a high/2 variant (e.g. smull). By extending a MOVI (or DUP, before this patch), we can avoid an ext on the other operand of the long instruction, e.g. turning: ext.16b v0, v0, v0, #8 movi.4h v1, #0x53 smull.4s v0, v0, v1 into: movi.8h v1, #0x53 smull2.4s v0, v0, v1 While there, add a now-necessary combine to fold (VT NVCAST (VT x)). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@239799 91177308-0d34-0410-b5e6-96231b3b80d8 |
