[llvm-dev] Dragon egg not recognizing Target ARM machine

Hello Team,

Good Morning!!

This is Vishnu Prasanth doing my master's thesis on improving llvm compiler
optimization.

Currently I am trying to build dragon egg and when I gave take, it is not
getting recognized for ARM machine.

Can you please help me with.

Below are the errors when I gave the below command inside dragon egg
directory

GCC=GCC_DIR/gcc LLVM_CONFIG=LLVM_DIR/install/bin/llvm-config make

You are aware that Dragon Egg is considered dead?

[llvm-dev] Dragon egg not recognizing Target ARM machine

Use llvm 3.5.2. It works for x86. May work for ARM.

That's the problem. LLVM 3.5 is so ancient it may or may not work, and
you'll be on your own either way; because virtually no-one else is using it.

Realistically you should be using Clang for C or C++ code, and probably
getting behind one of the thoroughly enjoyably unique Fortran front-ends if
that matters to you ($DEITY help you).
