Should NaN payloads be preserved through compilation?
...immediates as native doubles, or explicitly accept that NaN payloads in immediates will not necessarily be preserved through compilation. The ability to have custom NaN payloads in immediates could be useful to the WebAssembly community, but if the consensus is that LLVM should not guarantee their preservation, that's fine too. What do you think? Thomas -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20181109/50c738b2/attachment.html>

Letter case not preserved
All files transferred to my Samba server end up with lower case on the Unix box. Case is not preserved from NT to Unix. For example, if I copy C:\Temp\MyFile to a directory on the Samba server, it ends up there as myfile. What am I missing? I browsed the FAQ's in the web pages, without success...

[LLVMdev] Add a new information and preserve it in LLVM
Hello, I am trying to add some thing into LLVM, while I encountered some problems. So my situation is that I have some information W, some transform passes may change it, after these passes, I need the new W. What I did is to create an analysis pass similar to scalar-evolution or loopinfo, I can get the information by using getAnalysis<W>(); and preserve this information W by using

Strange problem with samba 1.9.18p10 on Solaris 2.6
Hy, I have currently a big problem with Win95 clients generating files with invalid inode types. This only happens with Quark documents created from scratch. Example: ?rwxrwxrwt 1 falkenbe av 35638891 Jul 29 16:02 /vol04/pc_03/Deerberg/ctp_Deerberg/test07 after copying the file it really is a file !! -rwxrwxrwx 1 schoenhe av 35638891 Jul 29 16:00

cyrus2courier or cyrus2maildir.py, which to choose?
What's the best utility to use to convert mail folders from a cyrus 2.2.13-10, on a debian 4.0 Etch system, to folders that can be used by dovecot? The http://wiki.dovecot.org/Migration/Cyrus page isn't too clear on what's the difference. cyrus2courier says "It should be able to preserve message UIDs, flags and 26 first keywords." cyrus2maildir.py says "preserves

preserving pop3 mail uids
Is there some way that message uids can be preserved when converting uw-pop3 mbox mail to dovecot maildir format? We've tried perfect_maildir, mb2md and the convert-tool that comes with dovecot but so far have been unable to preserve the message uids, which for example go from 44333a8500000003 before the conversion to 4434621500000003 afterwards.

[LLVMdev] [RFC] Setting preserve-bc-use-list-order=true by default
A while back I finished up some work [1] that Chad started to preserve use-list-order in bitcode [2], hidden behind an "experimental" option called `-preserve-bc-use-list-order`. I then added a similar `-preserve-ll-use-list-order` option for LLVM assembly [3].

Case Sensitivity vs. Case Preservation
Hi John, I recently wrote a little internal article in HP to try to graphically show the difference between case sensitivity and case preservation (Unix is case sensitive, NT only 'preserves case'). Perhaps this will help you understand it better, and configure your Samba server to do what you want. It was originally a ms word document format, so you may have to fiddle around with the window size to make it really readable... Any co...

GlobalsAA from GVN
Hi James, Thanks for the help. From the log, I could infer that SLP vectorizer is not preserving alias analysis, preventing GVN from getting the info. Although the first function to get compiled has GlobalsAA available during GVN, rest of them do not as SLP vectorizer run on that function invalidates GlobalsAA which is a module pass. Is there a way to force re-computation of a particular

[PATCH] fix sftp to preserve permissions and uid/gid
Sftp fails to correctly preserve permissions when fetching a file. It adds write permission for the owner (presumably so it can write the file). Sftp also fails to preserve the uid/gid. Added code so that if is running as root, uid and gid are preserved. patch is based on Openssh 3.4p1. *** sftp-client.c@@\main\1 Tue Oct 1 17:26:20 2002 --- sftp-client.c Tue Nov 5 10:22:52 2002

[PM] I think that the new PM needs to learn about inter-analysis dependencies...
...eserve all dependencies. And if an analysis A starts using a new analysis B, then every pass that preserves a pass that transitively depends on A must be updated or else there are use-after-free bugs. Not to mention out-of-tree passes. Perhaps the worst part is that without some sort of transitive preservation (or the opposite, transitive invalidation (with the transitivity in the opposite direction)) these sorts of bugs are a dynamic property of both the pass pipeline and the code being run on. For example, the reproducer I reduced for this particular bug involved a situation where: 1. A pass had to pre...

Preservation of CallGraph (by BasicBlockPass, FunctionPass)
I'm not sure about the old pass manager, but I think the new pass manager solves this issue. See llvm::updateCGAndAnalysisManagerForFunctionPass where it updates the call graph to be in sync with edges deleted by function passes. So I suspect the right fix is to use the new pass manager. -- Sanjoy On Mon, May 7, 2018 at 7:32 AM, Björn Pettersson A via llvm-dev <llvm-dev at

rsync feature needed: preserve atime
Often we need to preserve the information atime conveys, but I have found no way to get rsync to preserve this, nor any hint it is being worked on. It would be great if 'rsync -t' also set atime not just mtime -- or maybe a new option is desired for atime. I don't know if the -X mentioned in "NEWS file from CVS" covers this: > Added the --xattrs (-X) option to preserver

[PATCH] Add --preserve-atime switch to rsync
In the past there have been discussions about adding a switch to rsync to preserve the atime on files being copied by rsync. I needed this function for a project I'm working on and decided to invent it. I've attached the diffs. Note that this has the limitations describe in previous emails, namely that preserving atime causes ctime to not be preserved. *** Patch follows *** ***
