similar to: IR with no optimization

Thanks for the reply. Yes I'm doing static analysis. I'm trying to do points-to analysis actually. I care about whether pointer values point to the same memory location. I'm not sure if this is better to be done by Clang or LLVM? How to dump the unoptimized IR? By compiling with -O0? Thank you.

Are you doing this to enable optimizations, or to detect bugs? If the former, dealing with LLVM IR is probably your best bet, and you may find this to be helpful: http://llvm.org/docs/AliasAnalysis.html. If the latter, you probably want to hook into clang's StaticAnalyzer. I'm not familiar with whether or not you'd be able to do AA with it, but AFAIK it retains the full C/C++ AST (LLVM

Hi, I am sending this e-mail once again because it probably has been lost in abyss of Xen-devel/LKLM list. Here is the second version of memory hotplug support for Xen guests patch. This one cleanly applies to git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git repository, xen/memory-hotplug head. Changes: - /sys/devices/system/memory/probe interface has been removed;

Hi all, This is a new release of bio-cgroup which provides an IO tracking mechanism. The patches can be applied to the kernel 2.6.30-rc1 and you can also download them from the following site. http://people.valinux.co.jp/~ryov/bio-cgroup/ What's bio-cgroup all about? ============================ With this feature, you can determine the owners of any type of I/Os. This makes

This patch series enhances the existing virtio-balloon with the following new features: 1) fast ballooning: transfer ballooned pages between the guest and host in chunks using sgs, instead of one by one; and 2) cmdq: a new virtqueue to send commands between the device and driver. Currently, it supports commands to report memory stats (replace the old statq mechanism) and report guest unused pages.

Hi! I created a bug report (https://llvm.org/bugs/show_bug.cgi?id=23712) for this failure but then I realized that my approach may be wrong. The following D source contains a lazy variable: void bar(lazy bool val) { val(); } The lazy variable val is translated to a delegate. The signature and the first IR lines are: define void @_D7opover23barFLbZv({ i8*, i1 (i8*)* } %val_arg) #0 {

Hi all, This is a new release of blkio-cgroup v11. Changes: - The function cgroup_get_from_page() is added which determines to which cgroup a given page belongs. This function is introduced from Vivek's io-controller patch. Thanks Vivek. - Fix a type mismatch of the refcount of io_context. The refcount has been changed to atomic_long_t. This patch can be applied to 2.6.31-rc7. The

Hi all, This is a new release of blkio-cgroup v10. This release reduces IO tracking overhead and fixes an issue that could cause a deadlock since lock_page_cgroup() is no longer used. Thank you KAMEZAWA-san for your suggestions and pointing out the issue. This patch can be applied to 2.6.31-rc3-mmotm0716 and 2.6.31-rc4.
