Yep, I meant the contents. > `memory' denotes the reservation bit I guess). No, memory normally means any crazy fetch or store, so gcc won't defer storing stuff and wont hold stuff in registers across your asm. "*mem" is the only actual change, so expressing that only it is fetched/stored should give better code. Though the actual current usages are simple enough that it probably doesn't make any difference. _______________________________________________ Guile-user mailing list Guile-user@gnu.org http://lists.gnu.org/mailman/listinfo/guile-user
