What if in the registration interface we had three options: skippable, not skippable, and run at OptLevel::None. We'd need some way to communicate the OptLevel::None to the pass, but that doesn't seem terrible. -Andy -----Original Message----- From: David Greene [mailto:dag at cray.com] Sent: Monday, October 01, 2018 7:01 AM To: Fedor Sergeev <fedor.s...

...kes sense for function *only*, and immediately breaks down everywhere else. Frankly, OptNone should take no role in this particular discussion, and I feel like so far it has because "We've always done it this way". Second, I don't completely subscribe to the arguments towards not-skippable passes. Fundamentally: Who decides whether a pass is skippable or not? _When_ is a pass skippable, when isn't it? Neither the Pass nor the PassManager may actually decide that. The only things that do are the pipeline builder and the bisecter. Pipeline builder here means the driver tool that c...

...check. However new pass manager does not support it IIUC. We can either follow the legacy structure of skipFunction()/Module(), put skippability check in each single pass for new pass manager. Or since there is no optnone support, we now may also create label on each pass to determine it is skippable or not, and then do the check at pass manager level. 3. No region/basicblock/callgraphscc pass support for new pass manager? In legacy pass manager, OptBisect will be checked by skip() function on certain types of passes. like skipRegion(), skipBasicBlocks(). But I did not see implementat...

There's a lot of great literature focused on how to apply statistical models in R. It would be gr...

I am trying to get TLS to work with Outlook 2007 and I've hit a small problem. Whenever I start it up, I get this error: "The server you are connected to is using a security certificate that cannot be verified. The target principal name is incorrect." (yes/no choice of trusting) I first tried with a wildcard cert (*.elisand.com), and then tried with mail.elisand.com - both certs

Greetings! As the generic Pass Instrumentation framework for new pass manager is finally *in*, I'm glad to start the discussion on implementation of -opt-bisect through that framework. As it has already been discovered while porting other features (namely, -time-passes) blindly copying the currently existing legacy implementation is most likely not a perfect way forward. Now is a chance

In case a repository of virt-builder references files (e.g. the index) that cannot be downloaded (network issues, 404, etc) then virt-builder errors out on this situation. This is not a nice situation, from an user POV. This series does some refactoring to allow to better handle downloading failures, and handle the failures gracefully in virt-builder. RFC because I'm not yet too convinced
