Hi, I tried to compile the GCC front end of LLVM in a 16 CPU SMP machine with 64bit intel xeon CPUs. I tried with (GCC 4.1.0, 4.1.1, 4.1.2 versions). The LLVM compiles perfectly but when compiling the gcc front end the compiler crashes with a segmentation fault by reporting for memory leakages. Probably this is for the GCC's mailing list, but decided to ask if you know anything more about

Hi, I want to implement a new intrinsic in llvm that will denote a parallel section within a function. I followed the documentation for extending llvm (http://llvm.org/docs/ExtendingLLVM.html) but there is something about the working mechanism that is not clear for me. 1. Why do we have to add support for the C backend? Is this only necessary to transform the llvm assembly (bytecode) into C code

Hi, I try to compile LLVM and the GCC frontend for LLVM. The steps that I follow are first to compile LLVM and later to compile GCC front end. I tried to compile LLVM 1.8, 1.9 releases and the CVS versions. I tried to compile with different GCC compilers 3.4.0, 4.1.2 and 4.2.0 GCC compilers 3.4.0 and 4.2.0 fail compiling LLVM sources. GCC 4.1.2 works. I cannot compile GCC front end. When I

I want to see how OpenMP's parallel fit in the LLVM architecture, is it easy to implement or not. GCC is too heavy platform to work on.. Ferad -- Ferad Zyulkyarov Barcelona Supercomputing

Hi, I will try to explain by giving an example. Let's say that I have an intrinsic: int llvm.myintrinsic(int) I have a function: int myintrinsic_handler(int) When %var = call int %llvm.myintrinsic( int %arg ) is met in the code, I want the code generator put in its place: a call to function "myintrinsic_handler" (i.e. %var = call int %myintrinsic_handler( int %arg ) ) or

Yes, you I read that in the docs. Do you have a preferred gcc version that you would suggest me to work best. Unfortunately, version 3.4.2 that you suggest in your docs fails in compilation too. Thanks, Ferad -- Ferad Zyulkyarov Barcelona Supercomputing Center

GCC 4.1.x series is known not to compile LLVM. Its is well documented, avoid GCC 4.1.

I don't understand the following behavior for a simple S3 class. The auto-printing at the command line doesn't behave as I expect. I'm probably missing something, but it might be a bug. > print.testClass <- function(x, ...) cat("Class:", class(x), ":", x, "\n") > structure(1, class = "testClass") Class: testClass : 1 > print(1 *

Hello, I am the maintainer of the stringkernels package and have come across a problem with using S3 objects in my S4 classes. Specifically, I have an S4 class with a slot that takes a text corpus as a list of character vectors. tm (version 0.5) saves corpora as lists with a class attribute of c("VCorpus", "Corpus", "list"). I don't actually need the
