tools/lib/lockdep: drop leftover liblockdep headers

2021-12-09T17:37:49Z

Clean up remaining headers that are specific to liblockdep but lived in the shared header directory. These are all unused after the liblockdep code was removed in commit 7246f4dcaccc ("tools/lib/lockdep: drop liblockdep"). Note that there are still headers that were originally created for liblockdep, that still have liblockdep references, but they are used by other tools/ code at this point.

tools: Fix math.h breakage

2021-11-30T17:14:42Z

Commit 98e1385ef24b ("include/linux/radix-tree.h: replace kernel.h with the necessary inclusions") broke the radix tree test suite in two different ways; first by including math.h which didn't exist in the tools directory, and second by removing an implicit include of spinlock.h before lockdep.h. Fix both issues. Cc: Andy Shevchenko Signed-off-by: Matthew Wilcox (Oracle) Acked-by: Andy Shevchenko Signed-off-by: Linus Torvalds

tools lib: Adopt list_sort() from the kernel sources

2021-10-20T13:30:59Z

Add list_sort.[ch] from the main kernel tree. The linux/bug.h #include is removed due to conflicting definitions. Add check-headers and modify perf build accordingly.

objtool: Add frame-pointer-specific function ignore

2021-10-01T01:24:07Z

Add a CONFIG_FRAME_POINTER-specific version of STACK_FRAME_NON_STANDARD() for the case where a function is intentionally missing frame pointer setup, but otherwise needs objtool/ORC coverage when frame pointers are disabled.

tools: compiler-gcc.h: Guard error attribute use with __has_attribute

2021-09-13T22:51:41Z

When building objtool with HOSTCC=clang, there are several errors along the lines of orc_dump.c:201:28: error: unknown attribute 'error' ignored [-Werror,-Wunknown-attributes] This occurs after commit 4e59869aa655 ("compiler-gcc.h: drop checks for older GCC versions"), which removed the GCC_VERSION gating. The removed version check just so happened to prevent __compiletime_error() from being defined with clang because it pretends to be GCC 4.2.1 for compatibility but the error attribute was not added to clang until 14.0.0. Commit 815f0ddb346c ("include/linux/compiler*.h: make compiler-*.h mutually exclusive") and commit a3f8a30f3f00 ("Compiler Attributes: use feature checks instead of version checks") refactored the handling of attributes in the main kernel to avoid situations like this but that refactoring has never been done for the tools directory. Refactoring is a rather large undertaking and this has never been an issue before so instead, just guard the definition of __compiletime_error() with __has_attribute() so that there are no more errors.

compiler-gcc.h: drop checks for older GCC versions

compiler.h: drop fallback overflow checkers

2021-09-13T17:18:28Z

Once upgrading the minimum supported version of GCC to 5.1, we can drop the fallback code for !COMPILER_HAS_GENERIC_BUILTIN_OVERFLOW. This is effectively a revert of commit f0907827a8a9 ("compiler.h: enable builtin overflow checkers and add fallback code") Link: https://github.com/ClangBuiltLinux/linux/issues/1438#issuecomment-916745801 Suggested-by: Rasmus Villemoes Signed-off-by: Nick Desaulniers Acked-by: Kees Cook Reviewed-by: Nathan Chancellor Signed-off-by: Linus Torvalds
