Andy, et al., In ScheduleDAGInstrs::buildSchedGraph, the code for handling stores has this: if (!ExitSU.isPred(SU)) // Push store's up a bit to avoid them getting in between cmp // and branches. ExitSU.addPred(SDep(SU, SDep::Artificial)); This code does not seem to be in any way specific to compares; and in any case, at least on the PPC A2, scheduling stores in between the compa...

Hi. This patchset implements ia64/pv_ops support which is the framework for virtualization support. Now all the comments so far have been addressed, but only a few exceptions. On x86 various ways to support virtualization were proposed, and eventually pv_ops won. So on ia64 the pv_ops strategy is appropriate too. Later I'll post the patchset which implements xen domU based on ia64/pv_ops.

Hi. This patchset implements ia64/pv_ops support which is the framework for virtualization support. Changes from take 5 are rebased to Linux 2.6.26-rc3, bug fix ivt.S paravirtualization and multi entry point support. I believe these patches can be applied to the linux ia64 repository.

Hi. The patch I send before was too large so that it was dropped from the maling list. I'm sending again with smaller size. This patch set is the xen paravirtualization of hand written assenbly code. And I expect that much clean up is necessary before merge. We really need the feed back before starting actual clean up as Eddie already said before. Eddie discussed how to clean up and suggested
