Hi, Tom, Considering the severity of this bug, I would like to go ahead to push the fix into release_50 branch. The fix has been tested in the trunk and by various people as well and I will also make sure all BPF tests passed before the push. Thanks!

...good to know the 4.0.x patch release schedule and how to contribute. I found this email containing backporting timeline for 4.0.1 (already done): http://lists.llvm.org/pipermail/llvm-dev/2017-March/111530.html >From email, it is not clear to me whether we have upcoming 4.0.2 or not.

Not it stopped working. Does anybody know what have changed recently? Thanks! Yonghong

...https://reviews.llvm.org/rL306685 Some BPF users want them since their product needs to work on old linux distribution which has older versions of LLVM. Could somebody (maybe Tom Stellard or others) help clarify whether it is possible and what is the procedure/timeline for backporting? Thanks! Yonghong

Hi, I've tagged the 5.0.1-rc2 release, go ahead and start testing and report your results. -Tom

...(createTLOF(getTargetTriple())), isLittle(isLittle) { ... } It does not create a separate Subtarget, and its getSubtargetImpl() tries to get the value from SubtargetMap. Is there any downside to keep BPFTargetMachine as is? Or it is worthwhile to implement it in a similar way to X86/ARM? Thanks!

...e non-None address space is specified in the type. Is this a bug? Or this is the expected behavior? I am asking since linux kernel has a lot of codes which did pointer arithmetic where pointers have address space attributes. (currently those address spaces are sparse tool checking only.) Thanks, Yonghong

...unit tests are not impacted as well as expected. I have applied the patch to the trunk. Besides your other work to support 32bit abi, it would be interesting to see how new 32bit register can be used in 64bit architecture which may help improve performance and/or reduce instruction count.

I'm sure this must be a nls() newbie question, but I'm stumped. I'm trying to do the example from Draper and Yang (1997). They give this snippet of S-Plus code: Specify the weight function: weight < - function(y,x1,x2,b0,b1,b2) { pred <- b0+b1*x1 + b2*x2 parms <- abs(b1*b2)^(1/3) (y-pred)/parms } Fit the model gmfit < -nls(~weight(y,x1,x2,b0,b1,b2),

Hi Sanjoy, Yes, that's exactly what we have been looking at recently here, but the region tags seem to make it possible to express the control flow as well, so I think we could start with reg ions+metadata, as Hal and Xinmin proposed, and then figure out what needs to be first class instructions. --Vikram Adve > On Jan 19, 2017, at 11:03 PM, Sanjoy Das <sanjoy at
