No.

We used to have a pretty strict defintion about what a compiler was, and
what an interpreter was.  You did the compile things at compile time,
and then you the the interpreter things at runtime.

No more.  We have Just in Time compilers.  They do their compiling
at run time.  Or perhaps 'there is no such thing as compile time
any more'.
