[LLVMdev] Inserting pthread_create call into sequential code
Hi, I was working on multithreading a cross iteration loop. I want to insert a pthread_create function call and use other pthread functions into my LLVM IR. Issue is how do i get these functions using module->getOrInsertFunction("pthread_create"), since the function might not be there in IR and then insert function calls to these functions. So, crux is how do i call pthread...

libasan bug: pthread_create never returns
Hi all, We observed that under certain circumstances pthread_create() (libasan implemention) does not return. The conditions are the following: - address sanitizer enabled - main and child thread run on the same CPU (affinity) - real-time scheduling policy for both threads - different scheduling priority values (this includes the case of setting a real-time po...

[LLVMdev] lli -force-interpreter complains about external function
Hi Nick: Thanks for pointing me to libffi. Recompile LLVM with libffi does solve the problem of printf. But it still has other problems: 1) sinf() returns 0 in the interpreter, but returns correct value in JIT (see hellosin.c) 2) calling pthread_create cause lli to crash in the interpreter mode, but no problem in JIT (see phello.c). My questions are: i) can I call any arbitrary external function in the interpreter? ii) how do I specify the dynamic library (where the external function is implemented), when I call the interpreter? Thanks Xu hel...

NPTL problem on Centos 4.4
...39;ve been googling and not finding much that is helpful. At work I've got a multi-threaded program targeted at Linux. It compiles on RHEL 2.1 and 3, and is targeted at 2.1, 3, and 4. UP until today, the binary built on 3 has worked fine on 4. But on RHEL4 update 4 it dies a horrible death in pthread_create. I have reproduced the problem on Centos 4.4, where I am tyring to debug it. I thought it might be some newly-introduced binary incompatibility in the U4 update, so I recompiled it on Centos 4.4, and it does the same thing. This code has been running for 5 years both in-house and at dozens of cu...
