Hi R users: I don?t know if anybody have had the same problem with 'step()' funtion. If I type the commands ------------------------------------------------------------------------------- testData<-read.table("testData.dat",header=T) model1J<-glm(MCHNV~offset(Offset1),data=testData,family="poisson") step(model1J,direction="forward", scope=(list(upper=~IA+IM+altura+Region+Region:IA+Region:IM+Region:altura+offset(Offset1), lower=~offset(Offset1)))) --------------------------------------------------------------------...

...de may trigger assertions, crash, or miscompile when encountering such a modified GEP. I think it is unfeasible to change all code to properly handle the new form at once. 2. Johannes' interpretation is to add some kind of metadata to GEPs, in addition to the naive computation, such as: %offset1= mul i64. %i, %n %offset2 = add i64, %j, %offset1 %1 = getelementptr double, double* %A, inrange i64 %offset2 [ "multi-dim"(i64 %n) ] This was not obvious to me. The code above uses operand bundle syntax. During our discussing for this RFC we briefly discussed metadata, which unf...

Dear all: I have a shapefile in UTM coordinate system and I would like to transform it to Lat/Log coordinates (WSG84). The package PBSmapping contains function convUL to transform between the two coordinate systems when data is in the form of a data frame with attributes specifying the coordinate system. However, when shapefiles are imported using function read.shape (package maptools), a list

Hi I have asked the clang mailing list if it can be done in clang. However, i would like to also check if it can be done as a BC level transformation. I would like to address aggregates (structures, arrays) in a linear fashion and in terms of the simplest target type that is embedded in these data structures, So a 2 dimensional array becomes a single dimension array. A structure with a

Adding an intrinsic is easier than adding or extending an existing instruction, as suggested by

Hello, Persuant to feedback, http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-August/052927.html here is a new proposal for detailed struct assignment information. Here's the example showing the basic problem: struct bar { char x; float y; double z; }; void copy_bar(struct bar *a, struct bar *b) { *a = *b; } The solution I now propose here is to have front-ends describe the copy using

Hi Nick, I tried to rework changes as you requested. One of patches (0004 with extra assertions) has been removed. > + bool isEquivalentType(Type *Ty1, Type *Ty2) const { > + return cmpType(Ty1, Ty2) == 0; > + } > > Why do we still need isEquivalentType? Can we nuke this? Yup. After applying all the patches isEquivalentType will be totally replaced with cmpType. All

Hi, This is a proof of concept of GPU forwarding for Linux guest on Linux host. I'd like to get comments and suggestions from community before I put more time on it. To summarize what it is: 1. It's a solution to bring GPU acceleration for Linux vm guest on Linux host. It could works with different GPU although the current proof of concept only works with Intel GPU. 2. The basic idea

This patch series is based on the VM introspection patches (https://lore.kernel.org/kvm/20200721210922.7646-1-alazar at bitdefender.com/), extending the introspection API with EPT Views and Virtualization Exceptions (#VE) support. The purpose of this series is to get an initial feedback and to see if we are on the right track, especially because the changes made to add the EPT views are not small
