However, GPGPU-Sim should still work + with applications written for older versions of CUDA.) +- Fixed splash screen: was reporting incorrect version +- Fixed bug comparing strings in basic block formation code +- Fixed bug with additional basic block (which lead to incorrect postdominator + analysis on some benchmarks with recent versions of CUDA) +- Fixed "warning: "/*" within comment" when building. +- "Other general improvements" |
