[LLVMdev] GCC assembler rejects native code generated by LLVM
I successfully compiled CVS HEAD yesterday on my win32 machine using
Visual C++ Express (2005). I also have Mingw tools installed. I wrote
a simple hello world application and generated native assembly code
using llvm. When I tried to feed the code into GCC, it rejected it
with "junk at the end of line" error messages. Shouldn't GCC be able
to assemble this code? I realize win32 port

[LLVMdev] Exception handling in JIT
Hi everyone,
Here's a patch that enables exception handling when jitting. I've
copy/pasted _many_code from lib/Codegen/DwarfWriter.cpp, so we may need
to factorize it, but the functionality is there and I'm very happy with
it :)
lli should now be able to execute the output from llvm-gcc when using
exceptions (the UnwindInst instruction is not involved in this patch).
Just add the
