I am making my first attempts at using some Fortran code with R, and so far it's going OK. To print from my Fortran programs, it seems I need subroutines dblepr, realpr and intpr. From the excellent "Writing R Extensions" document: "Three subroutines are provided to ease the output of information from FORTRAN code. subroutine dblepr(label, nchar, data, ndata)

Hi, Win95 version, trying to build multiv. Following error (no mention in faq etc, but someone may have mentioned it recently). Appreciate any help. ------- Building multiv.dll from multiv.a -------- echo LIBRARY multiv > multiv.def echo EXPORTS >> multiv.def nm multiv.a | sed -n "/^........ [DT] _/s/^........ [BCDRT] _/ /p" >> multiv.def gcc -mdll

Hi I've built a dll using Fortran code and can call it by either R or Fortran. Calling by the former gives me the wrong answer and the later gives the correct answer. From what I've read, it looks like I should use the subroutines DBLEPR, INTPR and REALPR to get values to show up in R which I hope will allow me to find the error. I've downloaded the R-2.12.0.tar.gz but have

Hi, everyone. This may be properly a fortran question rather than an R question. I'm trying to add a few print statements to otherwise working fortran code in one of the libraries so I can see what's going on in the code. I have no problem doing so on an SGI machine, but under LinuxPPC I've run into a problem. The code compiles and creates a shared object (.so), but when I issue

Hello Everyone, I want to raise a discussion about @llvm.experimental.guard intrinsic and reasons why we should give up using it. Here is an alternative approach to representation of guards that resolves some of fundamental flaws that the current guards have. Basically, this intrinsic was introduced to model the following situation: we want to check that some condition is true, and if it's

Hi Sanjoy, Thanks for feedback! As for memory effects, currently I use " inaccessiblememonly " for it. It allows to prove that it doesn't alias with any other load/store in the function, but doesn't allow CSE to eliminate it. It is not actually super-cool, because there is no way that we can safely hoist it out of loop (and sometimes we want to, for example to make unswitching).

Hello, I am trying to compile R using the Sun WorkShop 6.0 (Forte) compilers. I don't think I am having a problem with the compilers, but instead with figuring out how to modify the R configuration to use non-Gnu compilers. I found in your documentation that one should modify the config.site file to change compilers, compiler flags, library paths, etc. I made modifications in this file,
