Author: manu Date: Mon May 25 12:42:55 2020 New Revision: 361449 URL: https://svnweb.freebsd.org/changeset/base/361449 Log: linuxkpi: Add __same_type and __must_be_array macros The same_type macro simply wraps around builtin_types_compatible_p which exist for both GCC and CLANG, which returns 1 if both types are the same. The __must_be_array macros returns 1 if the argument is an array. This is needed for DRM v5.3 Sponsored-by: The FreeBSD Foundation Reviewed by: hselasky Differential Revision: https://reviews.freebsd.org/D24953 Modified: head/sys/compat/linuxkpi/common/include/linux/compiler.h Modified: head/sys/compat/linuxkpi/common/include/linux/compiler.h ============================================================================== --- head/sys/compat/linuxkpi/common/include/linux/compiler.h Mon May 25 12:41:44 2020 (r361448) +++ head/sys/compat/linuxkpi/common/include/linux/compiler.h Mon May 25 12:42:55 2020 (r361449) @@ -111,4 +111,7 @@ #define _AT(T,X) ((T)(X)) +#define __same_type(a, b) __builtin_types_compatible_p(typeof(a), typeof(b)) +#define __must_be_array(a) __same_type(a, &(a)[0]) + #endif /* _LINUX_COMPILER_H_ */
