[PATCH 0/3] selftests/futex: clang-inspired fixes

by John Hubbard

Hi, Here's a few fixes that are part of my effort to get all selftests building cleanly under clang. Plus one that I noticed by inspection. Enjoy! thanks, John Hubbard John Hubbard (3): selftests/futex: don't redefine .PHONY targets (all, clean) selftests/futex: don't pass a const char* to asprintf(3) selftests/futex: pass _GNU_SOURCE without a value to the compiler tools/testing/selftests/futex/Makefile | 2 -- tools/testing/selftests/futex/functional/Makefile | 2 +- tools/testing/selftests/futex/functional/futex_requeue_pi.c | 2 +- 3 files changed, 2 insertions(+), 4 deletions(-) base-commit: f03359bca01bf4372cf2c118cd9a987a5951b1c8 prerequisite-patch-id: b901ece2a5b78503e2fb5480f20e304d36a0ea27 -- 2.45.0

[PATCH v2] selftests/net: suppress clang's "variable-sized type not at the end" warning

by John Hubbard

When building with clang, via: make LLVM=1 -C tools/testing/selftest ...clang warns that "a variable sized type not at the end of a struct or class is a GNU extension". These cases are not easily changed, because they involve structs that are part of the API. Fortunately, however, the tests seem to be doing just fine (specifically, neither affected test runs any differently with gcc vs. clang builds, on my test system) regardless of the warning. So, all the warning is doing is preventing a clean build of selftests/net. Fix this by suppressing this particular clang warning for the selftests/net suite.

[PATCH v2] selftests/user_events: silence a clang warning: address of packed member

by John Hubbard

When building with clang, via: make LLVM=1 -C tools/testing/selftest ...clang warns about "taking address of packed member 'write_index' ". This is not particularly helpful, because the test code really wants to write to exactly this location, and if it ends up being unaligned, then the test won't work (and may segfault, depending on the CPU type). If that ever comes up, it will be obvious and can be fixed. But all it's doing now is prevent a clean clang build, so disable the warning.
