I'd use max_align_t directly, except that it got added in C++11, and this test should be able to run in C++98 and C++03. Using a large type instead of a char also makes it easier to avoid making two padding values that look different, but aren't actually all that different due to internal padding. Just starting at a high prime wouldn't fix this, as then I have to ensure that consecutive values are separated by at least sizeof(void *). http://reviews.llvm.org/D15539 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
