![]() On 32-bit targets we can't use the scalar instruction so we insert the scalar into a vector and use packed conversions. Previously we used either v4f32->v4i64 or v4f64->v4i64 to avoid some complexity creating target specific ISD opcodes for v4f32->v2i64. But this causes extra vzeroupper instructions and possibly frequency throttling on Intel CPUs. This patch changes this to create a 128-bit vector and uses a target specific ISD opcode if needed. |
