...is is by no means official yet, but I put together a proof-of-concept svn-to-git conversion of the NUT source tree: https://github.com/clepple/nut If you are interested in experimenting with the repository, feel free to clone it, but if we identify any problems with the Git import from SVN, be forewarned that I might blow away this repository and start over. In particular, I guessed at some of the preferred email addresses committers (based on the svn2cl.authors file), so yell if there are any corrections. I added a few of the most recent SVN branches and tags to the GitHub repository. They are...

I'm assuming that this is the DSA analysis in the poolalloc module.

...normal (not rocket science) business (80-20 rule) can be done just as well in R in comparison with tools like SAS, Matlab, etc. Q2) I haven't tried the processing routines for much larger data-sets assuming "size" is not a constraint nowadays. I know that I should try out ... but any forewarnings would help. Is it likely that something that works for my "desktop" dataset is quite as likely to work when scaled up to a "cloud dataset"? Assuming that I do the clearing out of unused objects, not running into infinite loops, etc? i.e. is there any problem with the "...

Hi, I'm rotating my PGP keys, so this is a forewarning that the key used to sign the next release of portable OpenSSH will be different to the one I've used in the past. Hopefully the gnupg incantations that I recited have resulted in a new key that is correctly cross-signed by my old one so there should be a trust path across the rollover. Th...

...ures 3. File bugs and/or create reviews to remove the flag from each of the tests. There are two reasons I prefer this approach. First, new tests are "correct by default" while we clean up the existing problematic tests. Second, out of tree work has an easy path forward and reasonable forewarning. They can add the flag temporarily and fix problematic tests when time permits, rather it suddenly breaking their CI whenever open source flips the switch. > I suggest you file a bug with the complete list of test failures that > non-overlapping CHECK-DAG finds.

No, I don't believe such a transform exists, but it should be pretty easy to write. Just be forewarned that you can't safely promote allocas to global variables when they're used in loops or in functions that can be called recursively. You must either check for these conditions or assume a priori that you code does not do these things. -- John T. > > Does anyone know if there a...

...mi-space collector with Cheney scan, using the included shadow stack support to track roots. I'm writing everything in C, using llvm-gcc's gcroot attribute in a test app to mark GC roots where appropriate, which seems to work fine when translating to LLVM IR (and finally an executable). Be forewarned that this attribute should be considered ‘experimental’ at best. > Implementing a GC is actually quite new to me, so perhaps that's where I'm getting confused. Anyways, suppose I have a function that has a pointer to a GC-tracked object as a parameter and a collection can be triggered...

Hello, I'm looking for a way to identify dependencies of function-pairs (memory-dependency, control-dependency...) in order to parallelize them. For aliasing problems I use the DataStructureAnalysis. To solve simple memory- and control-dependency problems I want to use memdep. But unfortunately I even fail with following simple C++ example... int a( int n) { return n; } int b( int n) {

...essfully compiled all of libc into LLVM bytecode yet. Some libc functions are compiled to LLVM bytecode (see llvm/runtime), but many others are not; for those, we link against the native libraries after code generation. You can try compiling the parts of libc you need to LLVM bytecode, but be forewarned that it'll be tedious. C libraries (glibc in particular) seem to be designed to make life difficult for people who want to compile them. -- John T. > > > Maybe it's possible using the lli interpreter (which is a lot slower, > I know), instead of the analyze tool? > &gt...

...names in the shorewall docs: "I personally recommend strongly against using DNS names in Shorewall configuration files. If you use DNS names and you are called out of bed at 2:00AM because Shorewall won''t start as a result of DNS problems then don''t say that you were not forewarned." Having been stung by this a few times over the years, I''m wondering if anyone has come up with a solution to this problem. Perhaps a conditional include file which will perform the lookups, and just ignore the rule if the dns lookup fails? Just wondering if someone has a crea...

Be forewarned, I am new to Linux. I am using Ubuntu 9.10 (Karmic Koala). I have installed wine (1.1.38) and I am able to run RollerCoaster Tycoon 3 both with and without a virtual desktop. It runs with no problems except for the fact that it does not receive keyboard commands! I have looked all over the In...

...t was ignorant of ownership and/or permissions). It would be great if rsync could verify that ownership settings actually took when they are set and report in the verbose output and/or logs if there is a discrepancy. This would help to aid those of us in setting up rsync-based backups and will forewarn us of related problems during full recovery of a backup. I hope this helps someone and/or aids the future development of rsync. -- MKoistinen -------------- next part -------------- HTML attachment scrubbed and removed

Hi, I'm doing llvm pass for OpenCL code which does some memory checking to verify that code does not access memory outside of the programs own statically allocated areas. To make dynamic check generation easier, I would like to collect all allocas and global variable definitions and create one big memory structure (for each global, local and private) containing all the allocated memory as
