Or should I obtain the ARM compiler provided by ARM (which is not free unfortunately)? I don't think you said aarch64 before, did you? Why do you need libquadmath for aarch64? Isn't long double always 128-bits on aarch64, and therefore you don't need additional libquadmath routines to support 128-bit floats?
