This patch set is a dependency of the generic red-black tree patch set, which I have now split up into three smaller sets. The major aim of this patch set is to cleanup compiler-gcc*.h and improve the manageability of of compiler features at various versions (when they are broken, etc.), and to add some needed features to bug.h (again, that are compiler-version-dependent). compiler-gcc*.h o Introduce GCC_VERSION - (e.g., gcc 4.7.1 becomes 40701) o Reorder all features based upon the version introduced (readability) o Change all version checks to use GCC_VERSION o Remove redundant __linktime_error o Introduce __flatten function attribute bug.h o Improve BUILD_BUG_ON(expr) - now generates compile-time error post-gcc-4.4 o Introduce BUILD_BUG_ON_NON_CONST(expr) macro, which simply wraps __builtin_constant_p and BUILD_BUG_ON o Documented (in BUILD_BUG_ON_NON_CONST doc-comments) the extensive discrepancies in the behavior of __builtin_constant_p throughout versions of gcc. o Introduce BUILD_BUG_ON_NON_CONST42 macro for compile-time-constant checks that are doomed to fail in older versions of gcc. -- To unsubscribe from this list: send the line "unsubscribe linux-sparse" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
