i1 true ^= -1 in DAG matcher?
..., so use a -1 for checking a true // 1-bit value. Which seems to reflect the same observation. Is this a bug or a feature?

Differentiate array access at IR level
Hi LLVM community, I am trying to differentiate access to different array elements, for example: for (int i = 1; i < 10; i++) { a[i] = a[i] + 10; b[i] = a[i - 1] * 2; } If it is possible to tell it loads/stores 3 different array elements: a[i], b[i] and a[i - 1] at IR level? Thanks for your time in advance! Best, Michael -------------- next part -------------- An HTML

How does dovecot determine users from /etc/passwd?
We're using dovecot on a help desk ticketing system. The system doesn't perform any cleanup of IMAP mailboxes so we have a regular cronjob doing this: /usr/bin/doveadm flags add -A '\Deleted' SEEN SENTBEFORE 12w && /usr/bin/doveadm expunge -A DELETED MAILBOX '*' Recently, doveadm has been reporting this: doveadm(nobody): Error: User initialization failed:

Sieve junks mail script creating links
My Junk mailbox is still filling up with hard linked emails. There are some junk mails with over 3000 hard linked files and over half a million files in the .Junk/cur folder. I had a handy script to remove them all by doing a find for inodes and sorting the list by age and keeping the olds hard link and removing all the others, but I now can?t find it :/ so I have just taken to periodically

Given one restrict pointer based on another, should they never alias?
We recently found an issue when using the full restrict implementation developed by Jeroen; it surfaces when compiling an obscure combination of std::valarray and std::indirect_array but I don't want to bore you with all the details. What it boils down to is this basic question about restrict: Given one restrict pointer based on another, should they never alias? As far as I understand the

amount of camelCase refactoring causing some downstream overhead
Hi Philip, While it's true we don't I think Valentin is reasonable in saying "hey, when people do this let's try to combine them if it makes sense". It's just being polite to everyone, especially if it doesn't risk the patches or upstream stability. I don't think there's a policy change being proposed, just a "hey, let's see what we can do in the

[PATCH 0/2] virtio-blk: improve handling of DMA mapping failures
Two patches are handling new edge cases introduced by doing DMA mappings (which can fail) in virtio core. I stumbled upon this while stress testing I/O for Protected Virtual Machines. I deliberately chose a tiny swiotlb size and have generated load with fio. With more than one virtio-blk disk in use I experienced hangs. The goal of this series is to fix those hangs.
