I am using pthreads. I was also wondering what will the llvm IR be for pthreads ?

...hen I change the order of the variables, the coefficient changes (see below). Can anyone point me to the reason R behaves this way? Is there anyway for me to force R to use all the variables? I checked the correlation matrices to makes sure there is no orthogonality between the variables.

Thanks a lot. A see the shared library in linux version. I initially tried doing this in cygwin where I dont see the shared library being built. Do u think it could have been cygwin that is the problem?

...t can convert decimal values into floating point numbers. i.e. say I have a decimal number 1110794174 (== 42355FBE in hex ) and (== 45.3435 as a float) essentially the mantissa and exponent representation needs to be used. Is there any way of doing this in llvm?

.... I tried the grep() but I get a message saying that the length of pattern >1 so only first element will be compared. But i want to check for each gene in the 100x100 matrix for its cluster number and then group it. I also tried the order() but it did not help either.

I believe because cygwin behaves like windows (it is just a posix layer over window) it doesn't have dynamic linking hence only static libraries have been built.

I am using opt , so i cm confused if i need to do this. On the other hand I modified my functionPass not to call TargetData , and I still get this error. My functionPass still calls Alias Analysis though.

...DIR/lib the LLVMHello.a and LLVMHello.la libraries are generated. But I am confused as to how to generate the .so library file from here. I am kinda new to compilers and hence the question I know is basic , but couldnt figure the answer out myself. Thanks a lot for your help.

Hi Sebastian, Sure! The bulk of LMDA was written by Aparna Kotha (CCd). It computes dependences between all instructions, computes the resulting direction vectors in the function, then associates them all with loops. At a high level, the dependence analysis consults with AliasAnalysis, and ScalarEvolution before resorting to attempting to understand the e...

...I use opt to load and run A , it gives the following error. LLVM ERROR: Bad TargetData ctor used. Tool did not specify a TargetData to use? I gather from some previous emails that this was not supported. Is it still not supported? and is there any way I can avoid this.

...he widths of values being written to a file using wrtite.fwf() ? For example, I used read.fwf(file, width.vector) to read a file. After making the necessary data manipulation, I want to write the data to a new file in the same width.vector format. Is there a way to specify this? Thanks in Advance Aparna [[alternative HTML version deleted]]

In order to generate shared libraries you need to have SHARED_LIBRARY and LOADABLE_MODULE defined in the Makefile.

Right. But there are 8 registers on the floating point stack from ST0 to ST7 and I think llvm is only using ST0 to ST6 in some code fragments. Could this be because of the assumption that X86::FP registers run from X86::FP0 to X86:FP6 ? --Aparna On Wed, May 25, 2011 at 2:28 PM, Jakob Stoklund Olesen <stoklund at 2pi.dk>wrote: > > On May 25, 2011, at 11:09 AM, aparna kotha wrote: > > > Hi Guys, > > > > I was working on some floating point intensive benchmarks and realize > that the floating point regist...

Hi All I am new to R and I am not sure of how this should be done. I have a matrix of 985x100 values and the class is data.frame. A sample of my dataset looks like this (Since its a huge dataset and it would make the screen look more complex, I am pasting only the first few rows and columns. V2 V3 V4 V5 V6 2 0.009953966 -0.01586103 -0.016227028
