[LLVMdev] Vector-select status update
Hi, As of recently, the LLVM code-generator started supporting vector-select instructions (select instructions where the predicate operand is a vector of booleans). This support includes efficient sequences for targets which have dedicated blend instructions (such as SSE4 and AVX), a slower implementation using vector AND/OR/XOR instructions for unoptimized targets, and scalarization for
