Maybe people would flip the RUN_SLOW_ON_AMD flag to false. :-)

- sanxiyn 9y agoAnecdotally, changes to ICC are evaluated (by management) on two metrics: improvement on Intel CPU, but also improvement on Intel CPU minus improvement on AMD CPU. The end result is similar to RUN_SLOW_ON_AMD flag. If you think this cheesy, consider this: you are a manager of Intel compiler team. Someone implemented an optimization that improves performance by 1% on Intel, but 10% on AMD. Do you think it is a good change? The change will be no-brainer on GCC, but consideration for ICC is necessarily different.
