Hi everyone, The WebAssembly backend recently had Bug 39448 <https://bugs.llvm.org/show_bug.cgi?id=39448> filed against it because NaN payloads in floating-point immediates are not preserved through compilation on 32-bit builds. I took a look and the corruption takes place when the immediates are converted from APFloats to be stored as native doubles in MCOperand. I assume this bug only appears in 32-bit builds because they are using x87 doubles that happen to not preserve all possible...

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...

...n 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 AU.addPreserved<W>();. Then the problem came, for the module pass, the information can’t be preserved. (I found this: To the best of my knowledge, the LLVM pass manager never preserves a FunctionPass analysis that is requested by a ModulePass; every time you call getAnalysis for a function, the FunctionPass...

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

...nalysis and preserves it. I am expecting MyAnalysis to be re-scheduled between MyCallGraphSCCPass and MyModulePass3 but it's not happening. If I set MyModulePass3 to not preserve MyAnalysis, then I see MyAnalysis re-scheduled after MyModulePass3. It seems like the fact that MyAnalysis is not preserved by MyCallGraphSCCPass is somehow not propagated outside the Call Graph SCC Pass Manager. Is there something wrong with that sequence ?

Are there any cases in which structure layout must be preserved besides for volatile accesses and if the data goes out to extern...

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

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...

...tal" mode, and turn `-preserve-bc-use-list-order` on by default. I've attached a patch that does this. Why? ==== Use-list order affects the output of some LLVM passes. A typical example is a pass that walks through basic block predecessors. The use-list order is deterministic, but not preserved when serializing the LLVM IR to bitcode or assembly. In rare (but frustrating) cases, this makes it difficult to reproduce a crash or miscompile from an intermediate result. For example, consider running an LTO build and serializing between the LTO optimization pipeline and the LTO codegen pipeli...

...in the CallGraph when doing the inlining. That will go away if I remove the setPreservesAll from the FPPassManager:: getAnalysisUsage (which I assume is too aggressive). Would it be correct to change the FPPassManager:: getAnalysisUsage to exclude "CallGraph Construction" from the set of preserved analyses, or am I missing something here? I assume that DeadInstElimination isn't preserving the CallGraph. Shouldn't that (automatically/dynamically) impact which analyses that are preserved from the BBPassManager and the FPPassManager for this pass structure? Regards, Björn ------------...

...39;t look good! I can understand 'filethree.txt' being converted to lower case; after all it is not an 8.3 filename, so it should fall under the auspices of the 'preserve case = no' option. But what about the other three? They are all good little 8.3 filenames. Why was case NOT preserved? Apparently, 'short preserve case' is dependent on 'preserve case'. That is to say, in order for 'short preserve case = yes' to work, 'preserve case = yes' must be set. Ok, lets move on to the case where we specify BOTH preserve case = yes and short preserve cas...

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.

.... Yay! This email is about one issue that I ran into testing the pipeline on test-suite. The issue arose in the wild as an interaction between lcssa and gvn. But the issue is extremely general. What happened is that BasicAA uses TargetLibraryInfo. If it makes a change, then LCSSA marks BasicAA as preserved (if it made no change, it would preserve all). The new PM then invalidates everything not marked as preserved by LCSSA. So it does not invalidate BasicAA but it does invalidate TargetLibraryInfo. Now BasicAA is holding dangling pointers to TargetLibraryInfo. GVN then goes to query BasicAA and thing...

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

...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.
