[Bug inline-asm/37188] New: There is no way to specify double precision floating point registers in inline asm arguments (VFP)

["siarhei dot siamashka at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Gcc manual, "5.38.4 Constraints for Particular Machines" section:

"ARM family??config/arm/arm.h?
          f        Floating-point register
          w        VFP floating-point register
          F        One of the floating-point constants 0.0, 0.5, 1.0, 2.0, 3.0,
4.0, 5.0 or
                   10.0
..."

Using "w" constraint allows to use single precision VFP floating point
registers. But this does not work for double precision.
