Michael Liao 9d796db3e7 Add alternative support for FP_ROUND from v2f32 to v2f64 ... - Due to the current matching vector elements constraints in ISD::FP_EXTEND, rounding from v2f32 to v2f64 is scalarized. Add a customized v2f32 widening to convert it into a target-specific X86ISD::VFPEXT to work around this constraints. This patch also reverts a previous attempt to fix this issue by recovering the scalarized ISD::FP_EXTEND pattern and thus significantly reduces the overhead of supporting non-power-2 vector FP extend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165625 91177308-0d34-0410-b5e6-96231b3b80d8		2012-10-10 16:32:15 +00:00
