Hi I just stumbled upon this paper. While i just skimmed over it it seems as if the authors say that their algorithm is more efficient than the llvm 2.3 algorithm? So i thought that might be interesting? http://pp.info.uni-karlsruhe.de/uploads/publikationen/braun09cc.pdf Disclaimer: I have no affiliation with the authors and stumbled in a slightly unrelated search over this paper.

The abstract clearly states they're counting the number of dynamic spills. That has almost nothing to do with performance. Someone would have to reproduce their experiment to verify that performance indeed improves. And alas, our field is notoriously unsc...

For spilling, I plan to use the Hack-Braun generalization of the furthest-first heuristic for SSA: http://pp.info.uni-karlsruhe.de/uploads/publikationen/braun09cc.pdf For coloring, there are a few different approaches you can take, e.g. dominator tree scan, puzzle-solving, or a modified graph coloring / coalescing heuristic like IRC. The best quality for the least amount of implementation effort is probably a dominator tree scan with register pref...

...ctly or indirectly. One approach is described in the paper "Register Spilling and Live-Range Splitting for SSA-Form Programs" by Matthias Braun and Sebastian Hack. It can be found here: http://pp.info.uni-karlsruhe.de/publication.php?id=braun09cc http://pp.info.uni-karlsruhe.de/uploads/publikationen/braun09cc.pdf This approach uses an approach similar to the BigBlock allocator (i.e. the MIN algorithm), but extends it from basic blocks to the whole CFG of a function and does it at the SSA level. The implementation is available as part of the libFirm project. Another research project can be fou...

Hi all, I'd like to kill off the bigblock register allocator. Is anyone still using it? Cheers, Lang.

The allocator you are building, is it the Hack's and Goos's polynomial time algorithm?

...al costs aren't propagated unlike R1 and R2. In fact, there is a rule "RM" proposed by Buchwald [1] that seeks to fix a very similar case to this. What do you think?

I can only reproduce on Windows, but reliably (both 4.0.0 and 4.0.2): $> R --vanilla x <- c(0L, -2e9:2e9) # > Segmentation fault Tried to reproduce on Linux but the above worked as expected. Not an issue merely with the length of the vector; for example, x <- rep_len(1:10, 1e10) works, though the altrep vector must be long to reproduce: x <- c(0L, -1e9:1e9) #ok Segmentation

Dear list-reader, by running the following script: library(zoo) sessionInfo() search() packageDescription("zoo") data(EuStockMarkets) dax <- as.zoo(EuStockMarkets[1:10, "DAX"]) daxr <- diff(log(dax)) identical(as.vector(qnorm(daxr)), qnorm(coredata(daxr))) qqnorm(coredata(daxr)) qqnorm(daxr) qqnorm() produces an error: > qqnorm(daxr) Fehler in if (xi == xj) 0L

Hello, I need some help running a somewhat old windows program on wine. I am trying to run powdercell (XRD refinement thingy), here you can find the homepage of the program (sorry it is in german): http://www.bam.de/de/service/publikationen/powder_cell.htm The only report about this program dates from 2008, and I can't really tell how successful it was: http://appdb.winehq.org/objectManager.php?sClass=version&iId=2366 Let's go to the specs. I am running wine 1.2.3 on an imac 2.7Ghz Intel Core i5. I created the directory w...

Also $ sudo chown -R xyz:staff ~/R # sudo su; su xyz; groups web-content staff Not just vim-R-plugin -problem anymore, more pkg -installation -prob, doubting perms/group -issue but fixed them in accordance by Dirk's hints.
