eric/Lets_build_a_compiler: The GNU Modula-2 version of the "cradle", described in "Lets build a compiler" by Jack Crenshaw. The original version uses Pascal as programming language and generated 68000 assembly. I changed the language to Modula-2, and the generated assembly is AMD64. The assembly generated can be assembled, linked and executed. Commands to compile and assemble : gm2 -fiso -o cradle7 cradle7.mod nasm -f elf64 -g -F dwarf cradleasm7.asm -o cradleasm7.o ld cradleasm7.o -o cradleasm7 @ 3bdb4407c560808497544e3c670d471e8df180a0
