Take some time to look over the opcodes/ part of binutils.  That's the
area where CGEN-generated assembler/disassembler kernels are put.  The
CGEN modules that do that work are all already in the cgen/*.scm files.

No, machine-generated files should be left alone.

It is not a simulator's job to create the executables you want to run
on it.  You need a toolchain, one way or another.  CGEN can help generate
the kernels of various associated tools, but there is still a considerable
amount of work involved in porting, say, gcc, gdb, and even the more minor
programs.
