Marko Mäkelä cdaa1d768e MDEV-11349 (1/2) Fix some clang 4.0 warnings ... In functions that declare pointer parameters as nonnull, remove nullness checks, because GCC would optimize them away anyway. Use #ifdef instead of #if when checking for a configuration flag. Clang says that left shifts of negative values are undefined. So, use ~0U instead of ~0 in a number of macros. Some functions that were defined as UNIV_INLINE were declared as UNIV_INTERN. Consistently use the same type of linkage. ibuf_merge_or_delete_for_page() could pass bitmap_page=NULL to buf_page_print(), conflicting with the __attribute__((nonnull)).		2016-11-25 12:43:34 +02:00
