An off by one error, which you got it right for aarch64.

As for ppc64le, I can't test it, but if anyone is interested, assuming abi
remains the same, I would say the only thing depends on the endianness is the
storing of float as int, in
x15.c
917 #if defined(__PPC64__)
918 /* +1 put the float in low bits in dv, but dd has to be D */
919 *dv=0; *(((float*)dv++)+1)=(float)(dd[dcnt++]=*(D*)xv);
There wouldn't be a +1.
