Hi David, I'm catching up on email at the moment so I don't know if you've done this, but patches should go to llvm-commits for review if you wouldn't mind. Thanks! -eric On Thu Dec 12 2013 at 8:39:19 AM, David Woodhouse <dwmw2 at infradead.org> wrote: > This attempts to address http://llvm.org/bugs/show_bug.cgi?id=18220 > It also fixes a test which was requiring

I am attempting to create an instruction which takes a single 64-bit immediate. This doesn't seem like a thing that would exist already (because who needs an instruction which just takes an immediate?) How might I implement this easily? Perhaps I could use a format which encodes a register, which is then unused? Thanks for the help. Gus -------------- next part -------------- An HTML

This attempts to address http://llvm.org/bugs/show_bug.cgi?id=18220 It also fixes a test which was requiring the *wrong* output. I'm relatively happy with this part, and it even solves most of the hard part of feature request for .code16 in bug 8684 — which was actually why I started prodding at this. But I could do with some help with the 16-bit signed relocation handling, which I've

The domain structure maintains several shadow mode stats, such as shadow page counts for l1 & l2, hl2 tables, snapshots, etc. These counts are not decremented properly when we free shadow pages.

tl;dr, I'd like to add my own instruction, but I'm running into problems due to my lack of x86 encoding/decoding understanding. Hello all. Currently, I'm working on adding my own x86 instruction. I have done this once before; the basic process I used was: 1. Find an unused opcode, e.g. 0xF1 in this table: http://ref.x86asm.net/coder32.html 2. Insert an instruction into

Hello, I've searched for an answer to no avail. I am wondering if anyone knows how to constrain certain correlations to be equal. I have family data with 2 twins per family plus up to 2 siblings. I would like to somehow constrain all the sibling correlations (twin-sib and sib-sib) to be the same while allowing the twin-twin correlation to be different. Here is some simulated code:

Hi, I'm working on a project that use llvm openrisc beckend (currently not part of the upstream). Right now I'm looking at a bug where llc generates memory instructions that has out-of-range displacement, for example l.sb 37668(r1), r2 in which 37668 is a 17 bit signed integer, but the instruction only allows 16 bit signed displacement. As a result, after running through the

Hi, It looks like the problem was with the RIP relative addressing. The original patch mistakenly removed the || DispForReloc part because I tough that the RIP relative addressing was done by the SIB encodings, but it is actually done by the shorter ones.

I am a novice R user, and I am having difficulty understanding R's influence plots. I am trying to remove outliers from a particular variable, "sib." I am able to generate influence plots and further outlier information such as below (which is a shortened example). For my analyses, I end up excluding the points R refers to, 7, 18, 26, and 105. However, my question is, how can I

Memory mapped and port I/O is currently broken under VMX when the partition is running in VM8086 mode. The reason is that the instruction decoding support uses 32-bit opcode/address decodes rather 16-bit decodes. This patch fixes that. In addition, the patch adds support for the "stos" instruction decoding because this is a frequently used way to clear MMIO areas such as the screen. As

Holding the vblk->lock across kick causes poor scalability in SMP guests. If one CPU is doing virtqueue kick and another CPU touches the vblk->lock it will have to spin until virtqueue kick completes. This patch reduces system% CPU utilization in SMP guests that are running multithreaded I/O-bound workloads. The improvements are small but show as iops and SMP are increased. Khoa Huynh
