I believe only x86 and powerpc use the target specific feature (that I added for x86 in the 4.3 time frame, and then added to powerpc last year). In terms of target_flags and target_flags_explicit, the powerpc no longer uses this field, since we have more than 32 flag bits, and needed to move the flag processing to something that is HOST_WIDE_INT sized instead of int sized. So, it won't matter if you redefine the flag once again. I don't believe the x86 uses it either (for much the same reason). So, if it fixes the other ports, I would say it is ok (but I haven't looked in detail at it). -- Michael Meissner, IBM IBM, M/S 2506R, 550 King Street, Littleton, MA 01460, USA email: meiss...@linux.vnet.ibm.com, phone: +1 (978) 899-4797
