Most do. Yep, and that code runs optimally on just that one machine. Andrew is talking about using a common distribution and the JIT optimizing the execution for whatever machine it is run on. In essence, the JIT is the compiler back end, but because it is running in only one environment, your machine, it can optimize for exactly that one environment without any input from you. ...snip... >> The most advanced JITs will even recompile a routine >> that is live on the call stack. > > Modern processors should be able to block that. Active code on > the call stack is part of the typical method behind buffer > overflow exploits. You are confused. The term "buffer overflow" should be the clue. They depend on writing to code space by overflowing a buffer in data space and having that data write into the executable region. At no time does this exploit expect to be able to execute code "on the stack". The two concepts are totally unrelated. >> Compare this with native compilers that typically have no idea >> of which processor the code will be run on -- could be Pentium >> Pro, could be K8, could be Sandy Bridge -- and have to do the >> best they can. > > A compiler can query or be told what target to compile for.

You mean adding the specifics of the target optimization to the run time code? That would be *very* inefficient. Multiple code versions is not a matter of being lazy, it is a logistics nightmare. Most distributions have perhaps two versions, 32 bit and 64 bit. Imagine the trouble in managing some dozen or more variations! The users will never know which to download. Rick
