...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 similar cases. By the way, I compile it without problems in mu personal 32bit architecture PC with the same version of compiler (4.1.2) Regards, Ferad -- Ferad Zyulkyarov Barcelona Supercomputing Center

...t. The machine has intel xeon CPU that is physically 32 bit but has 64 extension x86_64 (or something like that, I am not exactly sure). The error message that I get is bellow.

...cific code (native) from the llvm bytecode? 3. Can I introduce an intrinsic that is actually a call to my function that implements the logic? I suppose it is possible but unfortunately I couldn't figure it out. For example, in GCC we can write an intrinsic that translates to a C code.

Please, may you give me the correct combinations of tools that give me successfully compiled and linked binary set. Thanks, Ferad -- Ferad Zyulkyarov Barcelona Supercomputing Center

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 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 Center

I think that when Ferad said "in GCC we can write an intrinsic that translates to a C code" meant that the intrinsic would be expanded to have a body much as I'm planning on doing in the this PR1297. To my understanding, IntrinsicLowering doesn't support expansion to a function with a body. Or, am I jus...

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
