C++ weekly: Racer finds 82 GPU kernel bugs, LLVMhammer slows Triton

This week's C++ roundup: the Racer tool symbolically checks PTX kernels against reference implementations and found 82 bugs across 23 libraries, 76 of them previously unknown. LLVMhammer demonstrated a specialized Rowhammer fault in Triton's LLVM-based pipeline, slowing correct GPU kernels by 4–16% on NVIDIA and AMD.
