similar to: [LLVMdev] Instruction::getNext and Instruction::getPrev are private

Hi, I switched to the upcoming version 2.0 branch and porting my code from 1.9. Thanks there is not a lot to do. I found that Instruction::getNext and Instruction::getPrev are private. Is this intentional? If yes, what would you recommend instead using them? Thanks, Ferad

Hi Ferad! the change has been made with <http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of- Mon-20070416/047931.html> You have to use iterators now and "operator ++" etc. Hope this helps, cheers, Gabor

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

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 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.

Hi LLVM, I would like to apologize to all LLVM readers for receiving an inappropriate message from LLVM mail list originating from my mail account. Today I was acknowledged by the moderators of other mail lists for posting inappropriate material CCed also to people who I know. I suppose that my e-mail account was cracked and now I am tracing the logs. Once again, sorry for this inconvenience.

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

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 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

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

May you point me an intrinsic implementation that lowers to an llvm call. Thanks for advices ans hints, Ferad -- Ferad Zyulkyarov Barcelona Supercomputing Center

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 may be mistaken as I just took a quick look, but in ilist_node the function "getPrevNode()" actually calls a method on the previous node: NodeTy *getPrevNode() { NodeTy *Prev = this->getPrev(); // Check for sentinel. if (!Prev->getNext()) return 0; return Prev; } http://llvm.org/docs/doxygen/html/ilist__node_8h_source.html#l00058 Try checking if
