Okay, this should use `SmallVector` as well, don't bother dividing by the size because the one reported from the ELF is absolute. Then just make the data inside `uint8_t`. https://github.com/llvm/llvm-project/pull/76587 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
