All, The code generator operand class, MachineOperand, has an 8-bit TargetFlags field that the individual targets can use as they please. X86 and ARM use it to encode linker magic on symbol operands. It has been mentioned a couple of times on this list that it is not safe to use TargetFlags on register operands. This is because many target-independent passes are manipulating register operands

Hello All, now that the BUG 14343: (s3: vfs_full_audit: Add missing fcntl entry in vfs_op_names[] array.) was fixed I wanted to try 4.12 again. This is the relevant config which has been running for years: vfs objects = acl_xattr full_audit shadow_copy2 full_audit:failure = none full_audit:success = pwrite write rename unlink full_audit:prefix = IP=%I|USER=%u|MACHINE=%m|VOLUME=%S

Good morning list, is there a failure in that manpage? (I'm running Samba version 4.17.6-Debian) The example shows: [records] path = /data/records vfs objects = full_audit full_audit:prefix = %u|%I full_audit:success = open opendir full_audit:failure = all !open full_audit:facility = LOCAL7 full_audit:priority = ALERT But: - opendir is not shown within complete set of Samba VFS operations.

Hi, The attached patch implements sub.ovf/mul.ovf intrinsics similarly to the recently added add.ovf intrinsics. These are useful for implementing some vm instructions like sub.ovf/mul.ovf in .NET IL efficiently. sub.ovf is supported in target independent lowering and on x86, while mul.ovf is only supported in the x86 backend. Please review

Hi, I've encountered a strange problem while using FreeBSD 6.0 for our local mirror (mirror.math.uni-bielefeld.de) and thus is providing access via ftp, http, rsync and cvsup (all local and remote). The system crashes periodically with a kernel panic (panic: sbdrop). The uptimes between two crashes are going from a few hours to a few weeks. The system is a i386, Intel Pentium 4 based with

Use para_fill instead of directly setting the APIC ops to the result of the vmi_get_function call - this allows one to implement a VMI ROM without implementing APIC functions, just using the native APIC functions. While doing this, I realized that there is a lot more cleanup that should have been done. Basically, we should never assume that the ROM implements a specific set of functions, and

I recently updated my Rannotate application. The interface has been completely redone and there are lots of new features. The basic idea is to create searchable and user annotatable documentation for the Ruby on Rails API (think php.net). Check it out at - http://rails.outertrack.com * What is Rannotate? Rannotate is a Rails application and RDoc YAML generator that work together to provide

So there is a logic error that would prevent us from ever using NOP = relocations, thus stopping any unnecessary callouts into a VMI ROM. It = doesn't affect us so much, but could conceivably affect open source = implementations of a VMI ROM in the future. It is not absolutely = critical, but it would be extremely nice to get it fixed in 2.6.21 so = there are no broken older kernels

Hi all, I noticed that the x86 backend tends to emit unnecessary vector insert instructions immediately after sse scalar fp instructions like addss/mulss. For example: ///////////////////////////////// __m128 foo(__m128 A, __m128 B) { _mm_add_ss(A, B); } ///////////////////////////////// produces the sequence: addss %xmm0, %xmm1 movss %xmm1, %xmm0 which could be easily optimized into

I had a previous install on another computer with the following, and EQ worked perfectly there, with the following configuration: Laptop: HP dv6355 Graphics: NVIDIA GeForce Go 6150 (UMA) Processor: AMD Turion 64 X2 (1.8 GHz) Memory: 2 GB OS: Ubuntu 8.04 Wine: 1.1.4 Unfortunately, the computer was formatted and given to someone else, so I can no longer compare the configurations or run any tests

There seems to be a bunch of code for making certain that gcc still works even if --enable-gcc isn't used, so I'm assuming that it's at least supposed to be a supported configuration, and hence this issue that I found should probably be looked at: If you compile llvm-gcc-4.2 _without_ --enable-gcc, and then try to compile the following program, you get a rather nasty RTL error.

Hello all: This seires is an update of last version of multiqueue support to add multiqueue capability to both tap and virtio-net. Some kinds of tap backends has (macvatp in linux) or would (tap) support multiqueue. In such kind of tap backend, each file descriptor of a tap is a qeueu and ioctls were prodived to attach an exist tap file descriptor to the tun/tap device. So the patch let qemu to

Hi Linus, Here's a set of patches to update paravirt_ops and Xen for 2.6.24 A quick overview of the patchset: paravirt_ops: Remove the monolithic paravirt_ops structure, and replace it with smaller structures of related functions. Also, clean up the handling of lazy mode to make it easier to implement. x86/mm/init.c: remove a chunk of dead code Xen: - remove duplicate includes -
