Further it adapts the Makefile to account for the fact that clang uses a different option to configure the stack alignment than gcc (-mstack-alignment=N vs -mpreferred-stack-boundary=N) Matthias Kaehlcke (3): kbuild: Add cc-option-no-kbuild macro x86/build: Use cc-option-no-kbuild for boot code compiler options x86/build: Specify stack alignment for clang arch/x86/Makefile | 25 +++++++++++++++++-------- scripts/Kbuild.include | 5 +++++ 2 files changed, 22 insertions(+), 8 deletions(-) -- 2.13.1.508.gb3defc5cc-goog
