9.21 Advanced SIMD operations not affected by flush-to-zero mode

Some Advanced SIMD instructions can be carried out on denormalized numbers even in flush-to-zero mode, without flushing the results to zero.

These instructions are as follows:

  • Copy, absolute value, and negate (VMOV, VMVN, V{Q}ABS, and V{Q}NEG).
  • Duplicate (VDUP).
  • Swap (VSWP).
  • Load and store (VLDR and VSTR).
  • Load multiple and store multiple (VLDM and VSTM).
  • Transfer between extension registers and AArch32 general-purpose registers (VMOV).
