The reason this happens is simple. In vfp_get_double(), we have:
1: fmrrd r0, r1, d\dr
1: mrrc p11, 3, r0, r1, c\dr @ fmrrd r0, r1, d\dr
but in vfp_put_double(), we have:
1: fmdrr d\dr, r0, r1
1: mcrr p11, 3, r1, r2, c\dr @ fmdrr r1, r2, d\dr
Note the different registers. Change "r1, r2" to "r0, r1" and it
should work.
