This is 32 bit machine. 64 bit will definitely won't work due to bunch of stuff unimplemented: dwarf builtins, stack layout description, etc. -- With best regards, Anton Korobeynikov.

Hi Bill, is this a 64 bit machine? If so, did you make any adjustments based on http://lists.cs.uiuc.edu/pipermail/llvmdev/2007-August/010489.html ? Thanks, Duncan.

Hi all, I'm compiling this trivial program on Darwin: int main(int argc, char **argv) { try { throw argc; } catch(int i) { return i; } return 0; } However, it segfaults when I run it. I've attached the .s files generated by LLVM and GCC, but it looks as if LLVM isn't generating a gxx_personality_v0 section (like it does for Unwind_Resume, et al). Is this what's

Hi Anton, You're already a part of the llvm development team by participating actively on the llvm development list :) If you wish we can put you on: http://llvm.cs.uiuc.edu/Developers.html Great to have you on the team, welcome! We (Jeff, Morten, Paolo, the rest of the team and I) are looking forward to cooperate with you and to push win32 and mingw versions even further to stable and

How can a frontend tell LLVM to put a function argument on stack/register/etc?

I tried to ask for 32 and that didn't seem to help. MallocInst also seemed to ignore the 16 byte directive. For now, I'm just issuing all my loads as unaligned and that's working ok.

Did anything ever come of the work on exception handling for x86_64? I'm having problems with exceptions on linux x86_64. Today, on x86_64 with a recently updated working copy of llvm, I tried calling a JITted function that calls an external function that throws: thrower.cpp: (which gets compiled into a dynamic library) extern "C" void throwexception() { throw 5; } My

Despite the align-16 directive on the > alloca instruction, it is not always aligning to a 16-byte boundary. The stack is not necessary 16 bytes aligned on linux/windows. The vector is really sotred aligned relative to %esp, but %esp value is not good. This is known problem
