GMP 6.2.1 core2 x86_64 assembler error "operands invalid for `movq'"

[Simon Sobisch]

Environment:


   Version:           GNU MP 6.2.1
   Host type:         core2-apple-darwin11.4.2
   ABI:               64

linked files:

config.status: linking ../mpn/x86_64/core2/popcount.asm to mpn/popcount.asm
config.status: linking ../mpn/x86_64/core2/hamdist.asm to mpn/hamdist.asm


make -k builds everything without an error but those two above fail (I 
think in gas), details see below.


When doing a research on this issue I recognized in
	mpn/x86/pentium4/sse/popcount.asm
a comment "movq avoided due to gas bug" (which is in since GMP 4.3).

Maybe it is possible do do something similar for popcount.asm and 
hamdist.asm in mpn/x86_64/core2 ?
