The way vring endianness is being handled currently obfuscates the code in vhost_init_used(). This patch tries to fix that by doing the following: - move the the code that adjusts endianness to a dedicated helper - export this helper so that backends explicitely call it No behaviour change.

Hi there, I have following equations to be solved for a and b: a/(a+b) = x1 ab/((a+b)^2 (a+b+1)) = x2 Is there any direct function available to solve them without disentangling them manually? Thanks for your help.

Regarding performance, I've made a simple coverage with counters and compared it with AsanCoverage. AsanCoverage produces code like this: mov 0xe86cce(%rip),%al test %al,%al je 48b4a0 # to call __sanitizer_cov ... callq 4715b0 <__sanitizer_cov> A simple counter-based thing (which just increments counters and does nothing else useful) produces this: incq 0xe719c6(%rip) The

I am fitting a logistic binomial model of the form glm(y ~ a*x,family=binomial) where a is a factor (with 5 levels) and x is a continuous predictor. To assess how much ``impact'' x has, I want to compare the fitted success probability when x = its maximum value with the fitted probability when x = its mean value. (The mean and the max are to be taken by level of the factor

TL;DR: See subject. That is all. ---- First off, I want to say I'm sorry for doing this. =/ There were several issues that led to this: 1) There were several micro-design problems with the APIs as implemented in the core libraries of LLVM. These then fanned out to all the uses of these libraries making fixing these issues challenging as well. The fixes were also not happening in a timely

Folks, Finally, Syslinux 5.10 has been released. This release includes a merge of the 4.10 development branch, which means that there's a new network stack availble, based on the lwIP embedded TCP/IP stack. The jump from the previous 5.01 release to 5.10 may be a little confusing, but a new network stack is such a large change that it deserved a significant bump in the version minor number.

Hi all, Thanks to everyone's hard work over the last few months, the last child of the AArch64/ARM64 merge issue (http://llvm.org/PR19392) has just been resolved. So I think it's time to finish the job. I'd like to delete the AArch64 target and move ARM64 into its place: for now we'll accept both aarch64 and arm64 triples in all places, and they will all be redirected to the

Hi Yaron, Overall this looks great. There are a couple of remaining holes. Specifically, MCJIT inherits implementations of the FindFunctionNamed and runStaticConstructorsDestructors methods from ExecutionEngine which use the old Modules vector, so you'll need to override these in MCJIT. (The implementations are fairly trivial.) Beyond that I just have a couple of questions. First,

Hi Andy, Here is the patch. it incorporates: 1) your latest patch to SVN. 2) mcjit-module-state-optimization.patch. 3) the PtrSet changes. Other than the OwnedModules implementation there were other differences between 1) and 2), especially in the Finalize* functions, so please review that I got the right code. I got bitten by subtle bugs arising from MCJIT inheriting from EE: First, MCJIT
