From: Lukas Bulwahn Date: Wed, 7 May 2025 13:30:43 +0000 (+0200) Subject: Makefile.kcov: apply needed compiler option unconditionally in CFLAGS_KCOV X-Git-Tag: v6.16-rc1~95^2 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=582847f9702461b0a1cba3efdb2b8135bf940d53;p=thirdparty%2Fkernel%2Flinux.git Makefile.kcov: apply needed compiler option unconditionally in CFLAGS_KCOV Commit 852faf805539 ("gcc-plugins: remove SANCOV gcc plugin") removes the config CC_HAS_SANCOV_TRACE_PC, as all supported compilers include the compiler option '-fsanitize-coverage=trace-pc' by now. The commit however misses the important use of this config option in Makefile.kcov to add '-fsanitize-coverage=trace-pc' to CFLAGS_KCOV. Include the compiler option '-fsanitize-coverage=trace-pc' unconditionally to CFLAGS_KCOV, as all compilers provide that option now.
