I know that llvm can be used to convert c++ into c code. I was wondering if clang could do the same thing (seeing as clang was derived from llvm).
So can I use clang to convert c++ code into c code?
If you want to know why I want to do this here is my scenario:
PIC, which is a micro controller manufacturer, does not make c++ compilers, but does make c compilers for most of their products. I want to write in c++ and then as part of my build process, convert the c++ code into a temporary c file, which is then fed into the PIC compiler, and viola I have written c++ code for a PIC micro.
回答1:
Clang can read C++ and emit LLVM IR. You seem to be aware that LLVM can read IR and emit C (from your own link: http://llvm.org/releases/3.1/docs/FAQ.html#translatecxx). So Clang cannot directly emit C, but it can emit LLVM IR which you then turn around and convert to C. Two steps, and Clang is one of them.
