notes
-
this requires gawk, because of functions and the builtin
strtonum -
since none of the awks can read binary, you first need to pipe the classfile through hexdump
-
example (see run.sh):
javac Add.java && hexdump -v -e '/1 "%01u "' Add.class | awk -f jvm.awk
-
example (see run.sh):
what can it do?
- not a lot (eg. call methods and basic operations, see Add.java)
