Hi! We are compiling a very large C project in llvm and trying to execute it in interpreter. There is a problem with executing the generated bitcode. We are using lli.exe and llvm-gcc.exe from official 2.6 LLVM release. We have localized the problem to following c code: -------------------- int f(unsigned char x) __attribute__((noinline)); int f(unsigned char x) { return x - 1; } int main()

...en crash if we are very unlucky), whereas on jit it is working fine. We are using interpreter because our code is crashing on jit too and when using the interpreter it is much easier to iron out the problems. Although as it seems at the current state the interpreter is quite unreliable. Thank you, Kristaps.

...__fixunsdfdi, __divdi3 etc. Currently we have attached our own implementations of these functions to overcome this problem. What would be the correct way to do this on Visual Studio? Why does JIT generate such function calls at all instead of native code that executes needed operation? Thank you, Kristaps.

Well, the answer is pretty obvious then. These calls are not generated by JIT. They are already in your bitcode - they are generated by llvm-gcc. The purpose of these calls were alreade explained by Eli. You should either

Hi! We are running llvm jit x86 on MS Visual Studio 2005. It seems there is a bug in asm code in function X86CompilationCallback in file X86JITInfo.cpp. Current code sets stack pointer to invalid value in instruction "and esp, 16". Depending on current stack pointer value it sometimes overwrites ecx and edx registers with next three lines. We have fixed this problem by changing this

I assume I am doing(or not) something extremely simple that is causing my XP boxes to not see my linux(FC4) Samba server in the 'My Network Places'. I can access the shares by 'Map Network Drive' and using the IP address(192.168.0.1). I have set the workgroup name 'DAMEN' in the lmhosts file. 192.168.0.1 DAMEN I have set the workgroup in the smb.conf file.

Hello! We are experiencing a problem with jit generated instructions for arm target (we have built llvm gcc for arm arch using the llvm sources fetched from llvm svn a few days ago). It triggers assert in MachineOperand::getImm method (isImm() && "Wrong MachineOperand accessor") when the bitcode from the testcase (c code below in this email) is being run. We have found out that

Hi, not really a problem, but it's annoying: when I run smbstatus on my PDC it shows the ip addresses, not the names of clients. The PDC is 3.0.21a, acting as a wins server (name resolution from the clients works fine), the clients are 3.0.14a samba and Windows XP. Has anyone seen this before and/or knows how to fix it?
