8.15 VFP operations not affected by flush-to-zero mode

Some VFP 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:
  • Absolute value and negate (VABS and VNEG).
  • Load and store (VLDR and VSTR).
  • Load multiple and store multiple (VLDM and VSTM).
  • Transfer between extension registers and ARM general-purpose registers (VMOV).
