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

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

Emil: Do you know where I could get libstdc++ that has been pre-compiled to LLVM bytecode? I know you have been trying to get it compiled, but if there's an older version of it that's available that will be useful to me already. With it I can use llc to get the C version and then compile it using AMPC. Thanks. Napi On Mon, 2006-11-20 at 10:21 +1100, Emil Mikulic wrote: > On Sat,
