Subject: [PATCH 0/4] Clean up UBSAN Makefile
Date: Fri, 2 Oct 2020 15:15:23 -0700 [thread overview]
Message-ID: <20201002221527.177500-1-keescook@chromium.org> (raw)
Hi,
This series attempts to address the issues seen with UBSAN's object-size
sanitizer causing problems under GCC. In the process, the Kconfig and
Makefile are refactored to do all the cc-option calls in the Kconfig.
Additionally start to detangle -Wno-maybe-uninitialized, and disable
UBSAN_TRAP under COMPILE_TEST for wider build coverage.
Thanks!
-Kees

ubsan: Move cc-option tests into Kconfig
ubsan: Disable object-size sanitizer under GCC
ubsan: Force -Wno-maybe-uninitialized only for GCC
ubsan: Disable UBSAN_TRAP for all*config
