While developing iqtree_arm_neon, @joshlvmh found:

  • denormalized numbers are flushed to zero
  • only default NaNs are supported
  • the Round to Nearest rounding mode is selected
  • un-trapped exception handling selected for all floating-point exceptions.

_mm_setcsr should be supported to ensure consistent behavior.
