...ou use a plethora of tablegen tricks to handle all the variations on vector operations. I believe it's much more straightfoward to specify special constraints, like bypassing. It's fairly easy to extend certain opcodes with predicates (callbacks) that depend on immediate values or any other arbtrary info. See Javed and Florian's tutorial on the "new" machine model: https://www.youtube.com/watch?v=brpomKUynEA Itineraries are not strictly more powerful. The original motivation for the new machine description is that there were important issue constraints that weren't being co...

Hi, What is the best way to model a scheduler for a VLIW in-order architecture? I've looked at the Hexagon and R600 architectures and they are using itineraries. I wanted to understand the benefit in using itineraries over the per operand scheduling. I also found this thread from almost 2 years ago: http://lists.llvm.org/pipermail/llvm-dev/2016-April/098763.html At that time it seemed the

I''m currently researching an upgrade to (raid1-ed) btrfs from mostly reiserfs (which I''ve found quite reliable (even thru a period of bad ram and resulting system crashes) since data=ordered went in with 2.6.16 or whatever it was. (Thanks, Chris! =:^)) on multiple md/raid-1s. I have some questions that don''t appear to be addressed well on the wiki, yet, or where
