Hi Henrique, I have tried using -mergereturn and inserting a free into the predecessors of dominance frontier of malloc block and it caused double free. It is possible for multiple free's to be inserted on the path from malloc to an exit. For example, in the following CFG: BB10 (malloc) / \ BB11 BB12 ... / \ / \

Thanks.

Try breaking the critical edges (-break-crit-edges). This way, a new block will be created between BB13 and BB11 (call this BB11.break) and BB15 and BB12 (call this BB12.break). The predecessors of the dominance frontier will, thus, be BB11.break, BB12.break, and BB14. When we enter through a block with a call to malloc(), we will end up in one of the blocks in the dominance frontier (kind of).

Greetings Flac-landers, I have a brand new puter with xp pro 2002 sp2. I downloaded flac-1.1.4b and installed, but when I ran the installed software, it told me that it was unable to run as I do not have mscomctl.ocx on my system. I searched my puter and indeed it is not on it anywhere. I looked all over the site for the prerequisites needed to install, but did not find them. Can someone

Hi Hisham, Most likely the basic blocks are the headers of two different loops. Try running viewCFG() on the function in question to see if this is the case.

Hello, I have a question regrading the analysis pass that generates loop info from an .ll code. My previous understanding was there will be just one loop header(in the loop info) for a particular loop. But, when i use isLoopHeader() member function from the loop info class I get 'true' return value for two different basic blocks. Note both basic blocks are loop conditional block(break

Hello CentOS users, in the recent time I keep getting the logwatch warnings from my 2 dedicated servers running CentOS 7.4.1708. I guess because of the numerous kernel updates (because of Spectre+Meltdown) in the near past? Could someone please suggest me, which files in my /boot partition would be safe to delete? I would like to avoid the situation of having to boot the rescue partiton etc.

There is some interest lately in making a self-contained grub2 boot image - call it pvgrub2, used for booting paravirtual domU in xen where a grub2 config is installed. First attempt------------------ I first tried using the grub2*.src.rpm from the C7 vault. I configured as shown belowhttps://blog.xenproject.org/2015/01/07/using-grub-2-as-a-bootloader-for-xen-pv-guests/ for headers, I used

Hi all, When compiling some programs using the Mips backend i'm getting this assert message on lib/CodeGen/LiveInterval.cpp:227: "Range is not entirely in interval!" I don't know yet if it's something that is missing on the backend code or why the range to be removed it outside the interval, does anyone have any clue? A more detailed output is attached. The program i tried

/etc/fstab needs the UUID for the filesystem volume; so if you use blkid, find the line with the filesystem type and label you used when you created the file system, and use the uuid listed after UUID= The grub.cfg should have a boot parameter mduuid which makes mdadm in the initramfs aware that it should assemble the array as soon as it can. It ought to be able to discover what it needs from

Hi I did the dd iso to my USB. all is fine. I can mount the second partition (which is not iso 9660) and edit the grub.cfg file. Question is what do I run after that so my new menu option appears ? grub2-install /dev/sdd Is that the correct command to get grub to notice my new file ? Assuming sdd is the USB disk of course. Thanks, jerry

Hi, I've stumbled upon a case where I think gvn does a bad (wrong) optimization. It's a bit messy to debug though so I'm not sure if I should just write a PR about it a let someone who knows the code look at it instead. Anyway, for the bug to trigger I need to run the following passes in the same opt invocation: -sroa -instcombine -simplifycfg -instcombine -gvn The problem

Hi, I was wondering whether it's possible to run libvirtd inside a chroot environment. The assumption is that only one instance of libvirtd would be running on the machine at a time, but still, inside chroot. Currently in my chroot env I have: - /dev/kvm added with mknod - /dev/vhost-net added with mknod - mounted:   - /dev/net   - /dev/shm   - /run/dbus When I run libvirtd in

I am running an Intel x64 machine using UEFI to boot an SSD. Installing the latest yum update which includes grub2 and kernel 4.18.0-193.14.2.el8_2.x86_64 renders the machine unbootable, blank screen where grub should be, no error messages, just hangs. After some hours I managed to modify another bootable partition (containing older software) and boot it from there. After that, I? found out

I had CentOS 6 installed on an MBR hard disk. I converted the disk to GPT (with UEFI) and installed CentOS 7 on a new partition. CentOS 7 itself seems to work properly. Grub from CentOS 7 automatically created an entry for CentOS 6, but I get an error if I try to boot CentOS 6. The menu entry is: menuentry 'CentOS release 6.10 (Final) (on /dev/sda7)' --class gnu-linux --class gnu

Hi! We have a problem that the dom0 very often does not boot and hangs in the hypervisor - see screenshot. The last message is: (XEN) Dom0 has maximum 16 VCPUs (afterwards xen should overwrite the memory) We are using the xen kernel from kernel.org git. Kernel is 2.6.32.24-xen with Xen 4.0.1 Hardware is HP DL380. Is this a known problem? Any hints what could be the problem and how we can
