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
