Hallo,
According to their proponents virtual machines such as JVM and CLR are
the solution to all our (programming) problems, of which portability
is but one.


Maybe it's just because when I learnt programming the p-machine was
considered an interesting oddity, but with the exception of code that
really must run unchanged on unknown platforms, I fail to see what do
I gain from a virtual machine that I don't already get from a good old
compiler/runtime support/standard library chain.


After all, isn't gcc the most ported virtual machine of all?


Now, this being the compiler forum, I'm interested in learning about
the advantages of virtual machines from the compiler writer
perspective.


Thank you,
Nicola Musatti
