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 { goto

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

...__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.

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...

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

Need to know if anyone has compiled the libstdc++ to LLVM bitcode. If it's available please where could I download it from? Thanks. Napi
