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

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 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 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

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

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

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

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.

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
