Additionally, changes within a compiler can be tested and implemented in real time. Software only needs to be recompiled to take affect. Hardware changes, on the other hand, require a long design and verification process that can easily last years. There is the problem in a nutshell. Changing one line of code in the compiler is as risky as a processor core revision and requires as many years of verification. You produce a new rev of the compiler and it has to work with a lot of legacy code out there. In practice each new rev of a non-EPIC compiler will break your code somewhere, generally in the area of the optimizations it performs. Which is why you tend to freeze the compiler version with the product version. The more people try and increase the performance of EPIC code by enhancing the compiler optimizations the more they will destabilize the existing codebase. I don't see a happy ending.
