## A crude Makefile to compile LLVM-Liberty-Eiffel compiler: it requires C++
## linkage even if Eiffel is usually lowered/compiled to C.

## compiling chain will be: Eiffel source code -> bytecode (.bc) -> assembler (.s) -> executable:

## * from assembler to executable with "gcc -o a_file a_file.s" (perhaps now llvm-as will do)
## * from bytecode to assembly with "llc example.bc"
