Dear all, I tried to install gstat package and add the following compilation error : ------------------------> * Installing *source* package 'gstat' ... creating cache ./config.cache checking for gcc... gcc checking whether the C compiler (gcc ) works... yes checking whether the C compiler (gcc ) is a cross-compiler... no checking whether we are using GNU C... yes checking whether

Thanks, Andy. I'm not sure how to solve that or my case given the DAG's basic-block limit. Probably CodeGenPrepare or SelectionDAGBuilder...or we wait until after isel and try to split it up in a machine instruction pass. I filed my example here: https://bugs.llvm.org/show_bug.cgi?id=33013 Feel free to comment there and/or open a new bug for the FP_TO_UINT case. On Thu, May 11, 2017 at

Dear all, I did post a message about problems on installing a package (gstat) which ends with a compilation error: ** libs gcc -I/usr/lib/R/include -mieee-with-inexact -fPIC -g -O2 -c block.c -o block.o gcc -I/usr/lib/R/include -mieee-with-inexact -fPIC -g -O2 -c chfactor.c -o chfactor.o gcc -I/usr/lib/R/include -mieee-with-inexact -fPIC -g -O2 -c copy.c -o copy.o gcc

Hello, by checking the precision of a convolution algorithm, we found the following "inexactness": We work with R Version 1.8.1 (2003-11-21) on Windows systems (NT, 2000, XP). Try the code: ## Kolmogorov distance between two methods to ## determine P(Poisson(lambda)<=x) Kolm.dist <- function(lam, eps){ x <- seq(0,qpois(1-eps, lambda=lam), by=1) max(abs(ppois(x, lambda=lam)-...

Hello R-Community, I have the following matching problem: I have two data.frames, one with an observation every month (per company ID), and one with an observation every quarter (per company ID; note that quarter means fiscal quarter; therefore 1Q = Jan, Feb, Mar is not necessarily correct and also, a fiscal quarter is not necessarily 3 month long). For every month and company, I want to get the

Some clarification after getting feedback from Craig Topper…. It’s probably best to say in the documentation that the llvm.nearbyint and llvm.rint functions “assume the default rounding mode, roundToNearest”. This will allow the optimizer to transform them as if they were rounding to nearest without requiring backends to use an encoding that enforces roundToNearest as the rounding mode for these

Hi Petr, The following is different line of thought which is posted in different form, maybe you have some wise input on it. "I need to find Efficient(tracktable) deterministic algorithm for Matching Weighted Graphs with bounded degree. Now we all know Graph matching is non-tractable but when degree of vertex has upper bound are there any tractable algorithm? Does this special case comes

This email is just to summarize a bit of digging I did last night into our attribute inference.  Unfortunately, I'm not going to have time to implement any of the gaps I noticed, but I figured someone else out there might be interested. *Missing Attributes* argmemonly - influences AA, particularly relevant for libraries which wrap build in functions which are annotated, but don't

The forthcoming C standard ( http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2454.pdf, 7.12.9.8) defines new function, `roundeven`, which implements

That’s a very reasonable statement, but I’m not sure it corresponds to the way we have typically approached this sort of problem. In

Hi, I've installed a program made for windows that is developed by our company. I installed the system on Ubuntu (Dapper Drake) using Wine. All other functions work fine, but when I tried to view the reports that were made by Crystal Reports the program displays the message "Application-defined or object-defined error." Any advice on how to get this work??? Thanks! Here is a copy
