c4 - C in four functions

An exercise in minimalism.

Try the following:

gcc -o c4 c4.c  (you may need the -m32 option on 64bit machines)
./c4 hello.c
./c4 -s hello.c

./c4 c4.c hello.c
./c4 c4.c c4.c hello.c

c4x86 - JIT compiler for x86 in 86 lines

An exercise in bit-twiddling masochism.

x86 only, not self-hosted!

gcc -m32 c4x86.c -o c4x86
./c4x86 hello.c
./c4x86 c4.c hello.c
