Dear Chris,

Thanks for your kind response!

The motivating of this work:

Clang can not build Linux https://bugs.llvm.org/show_bug.cgi?id=22830 and LLVMLinux patch was not be maintained? http://llvm.linuxfoundation.org/index.php/Main_Page
Clang analyzer Frontend can not static analysis glibc or Linux https://bugs.llvm.org/show_bug.cgi?id=31017 but analyzer checker is able to find the bugs for KDE :) http://www.leetcode.cn/2016/11/analyzing-code-for-kde-qt-open-source-components.html
For leaning GCC plugin, GIMPLE, LLVM IR, GCC PASS, LLVM PASS, CodeGen, etc. from llvm-gcc and dragonegg, thanks for your great job!

The usecase for dragonegg:

mips64-linux-gnu-gcc (WIP), arm-linux-gnu-gcc and x86 GCC Frontend -> GIMPLE -> LLVM IR -> Assembly or for KLEE
GCC Frontend -> GIMPLE -> Clang AST (WIP)

I am interested in some other frontend, such as flang-clang https://github.com/flang-compiler/clang/pull/28 and it is glad to learn from other developers :) https://gcc.gnu.org/ml/gcc/2017-09/msg00022.html

What is the usecase for dragonegg these days, now that Clang has great C++ support? Are you interested in Ada + LLVM or some other frontend? >> -Chris >>
