Non deterministic compilers can be viewed in at least three ways:
Non-deterministic compile time:
The ibm pl8 compler used a non deterministic hash code algorithnm,
which effected compile time performance but not generated code.
Non-deterministic code generated:
The Fx32 translator that I built at dec (translated x86 to alpha
binary) was non-deterministic It had a time bound on translation, so
that the compiler would be allowed to do more work on a fast machine.
Non-deterministic code changes as the program exeuctes.
The sun hotspot java compiler, as well as many other jit compilers,
recompile more aggressively routines that took a long time, so the
generated code might vary based on program input.
