Yup, that'll do it. Although you might want to do a little optimization
otherwise you're going to get a lot of C code on

[LLVMdev] Convert C++ to C. What is 0x0p+0 ?
Hi:
I've been able to compile the attached "helloworld.c" file converted
from "helloworld.cpp".
My question is how does one usually use __main() and CODE_FOR_MAIN()
in tying up with the rest of the code?
Attached here are the original "helloworld.cpp" and "helloworld.c"
files.
Thanks.

[LLVMdev] C++ to C
After converting a piece of C++ code to C one of the functions that are
generated is this:
_ZStlsISt11char_traitsIcEERSt13basic_ostreamIcT_ES5_PKc
Where is it defined and where can I find the source for it? I need the
source to compile it with a C compiler (AMPC) that will convert the C
code to Java Bytecode. If the above function is in C++ then I need to
convert it to C first.
Here's the

Hi Reid:
I'm not using gcc for this purpose but another C compiler called AMPC.
It compiles C

Here's how you can do a single file (i.e., an unlinked executable):
llvmg++ -c infile.cpp -o - | llc -march=c -o infile.cbe.c
Reid might be able to tell you how to do it with a single command using
the llvmc tool.

This is a method/function from the standard C++ library. You can link
it in at the bytecode level with:
llvm-g++ -o output.bc <yourfile.bc> -lstdc++
You might also be able to do:

[LLVMdev] Convert C++ to C. What is 0x0p+0 ?
Hi:
I'm interested in using llvm to convert C++ code to C code.
I used the following command to do this:
% llvm-g++ -c foo.cpp -o - | llc -march=c -o foo.cbe.c
In the resulting file foo.cbe.c there are many occurences of '0x0p+0'.
What is it used for? Here's a code snippet from the file foo.cbe.c
if ((ltmp_126_2 > 0x0p+0)) {
goto ltmp_363_19;
} else {

How does the C back-end of LLVM differ from the one in gcc2c developed
by SUN several years ago?

[LLVMdev] Problem building LLVM-GCC 4.0 Front End
I've read and followed the README.LLVM file that comes with LLVM-GCC 4.0
Front End source, but got the following error when compiling:
configure: error: You must specify valid path to your LLVM tree with
--enable-llvm=DIR
make: *** [configure-gcc] Error 1
I've done the following in csh before hand:
$ setenv LLVMOBJDIR /home/napi/proj/c2jvm/llvm/llvm-gcc/obj
Where did I go wrong?

This is defined in the C++ standard library. You can get the demangled

$ c++filt _ZStlsISt11char_traitsIcEERSt13basic_ostreamIcT_ES5_PKc
