  1. The time the x86 emulator team found code so bad they fixed it during emulation from devblogs.microsoft.com
    88 by paulmooreparks 1h ago | |

    Article: 8 min

    The article discusses a story from Raymond Chen about an x86 emulator team that found a piece of code so inefficiently written that they fixed it during emulation by replacing the loop-based initialization with a tight loop. The original compiler generated 256 kilobytes of code to initialize just 64 kilobytes of data, which offended the team enough for them to add special code to their translator.

    • Inefficient code generation by compiler
    • Unrolling loop into individual instructions
    • Special code added to translator for optimization
    Quality:
    The article provides a clear and concise summary of the story, with no apparent bias or sensationalism.
