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

Probably it would be good if this issue is included in the readme file for gcc-front end. Regards, Ferad -- Ferad Zyulkyarov Barcelona Supercomputing Center

Hi Anton, > What's the version of binutils you're using? I've seen such messages > with 2.16 series, but they were only warnings... The version of binutils is 2.17 By the way. I will use the opportunity to ask you again :) I tried to compile with gcc 4.0.4. It successfully compile LLVM but fails compiling LLVM's gcc front end. The problem is architectural 32 and 64 bit.

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

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 want to ask for a small help for creating an instruction that calls e member method of an object. I suppose that this is not a headache but I am impatient in learning :) I would be very thankful if you can show me an example snippet code that does this in LLVM. Below is described my case. Let's say I have a class TestClass class TestClass { int testMethod(int a); } and I want to

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

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

Hi, > IntrinsicLowering already does this. It lets you lower intrinsics to > arbitrary LLVM calls, including calls to external functions. I will try to do that in IntrinscLowering class. May you point me an intrinsic implementation that lowers to an llvm call. Thanks for advices ans hints, Ferad -- Ferad Zyulkyarov Barcelona Supercomputing Center
