[LLVMdev] ADDE on HW that doesn't have flags?
...Yes. What I think should happen is flags need to be less of a hack. There are two cases, instruction ordering/binding uses, and hidden dataflow uses. Modeling flags as registers on processors that have flags is not something I am qualified to speak on (though I suspect it would put an unnecessary compuational burdon on the scheduler and RA, esp on x86), but seperating control and dataflow flags so that an arch can say dataflow flags are always registers would let legalize know that addc was <int, dataflowflag> and that on the arch dataflowflag == register, so it could handle fixing up the types...

Performance of the acoustic echo canceller
...nce in any other softphones and how well does it work? I have the recording files, anyone would be interesting in taking a look? I wonder if there is something wrong with my input, setup...BTW: did anyone ever try to port the algorithm to hardware? I will do some profiling and implement the most compuation expensive function in the Xilinx FPGA.I would really appecriate if anyone can share some experience or provide adavise and suggest! I like to contribute my work to the Speex project if my project turns out to be good end. Regards,William __________________________________________________________...

[LLVMdev] ADDE on HW that doesn't have flags?
Thanks - that solves both problems. In the future, HW may have built in ADDE support, but will likely still not have flags - it'll just read 3 registers and write two. Any thoughts there?

Vignettes and CRAN checks
I'l like to chime in on the subject of vignette checks. I have one vignette in the coxme library that would be better described as a white paper. It discusses the adequacy of the Laplace transform under various scenarios. It contains some substantial computations, so I'd like to mark it as "never ever run this" for both CRAN and my local builds, my next update of it will

pnorm how to decide lower-tail true or false
Hi to all, maybe the last question was not clear enough. I did not found any hints how to decide whether it should use lower.tail or not. As it is an extra R-feature ( written in http://finzi.psych.upenn.edu/R/Rhelp02a/archive/66250.html ) I do not find anything about it in any statistical books of me. Regards Carmen

Plotting patient drug timelines using ggplot2 (or some other means) -- Help!!!
Hello All, Want very much to learn how to plot patient drug timelines. Trouble is I need to figure out how to do this today. So not much time for me to struggle with it. Hoping someone can just help me out a bit. Below are some sample data and code that produces what I think is the beginning of a very nice graph. Need to alter the code to: 1. Get the lines for the drugs to appear on the
