Actually the cited 4.0 sequence do not obey the const int x86_read_modify =
~(m_PENT | m_PPRO);
setting -march=athlon or using -Os makes the move go away. Additionally I get
following sequence out of 4.0 in SUSE distro:
movl term, %eax
movl 4012(%ebx), %ecx
movl 4028(%eax), %eax
imull %ecx, %eax
that also contains the extra memory move.
So I am going to close this as invalid.
