.llvm.call-graph-profile section is added by clang when the kernel is built with profiles (e.g. -fprofile-sample-use= or -fprofile-use=). The section contains edge information derived from text sections, so .llvm.call-graph-profile itself doesn't need more analysis as the text sections have been analyzed. This change fixes the kernel build with clang and a sample profile which currently fails with: "FATAL: modpost: Please add code to calculate addend for this architecture" Signed-off-by: Denis Nikitin <denik@xxxxxxxxxxxx> Reviewed-by: Nick Desaulniers <ndesaulniers@xxxxxxxxxx> --- scripts/mod/modpost.c | 1 + 1 file changed, 1 insertion(+) diff --git a/scripts/mod/modpost.c b/scripts/mod/modpost.c index b29b29707f10..64bd13f7199c 100644 --- a/scripts/mod/modpost.c +++ b/scripts/mod/modpost.c @@ -761,6 +761,7 @@ static const char *const section_white_list[] = ".fmt_slot*", /* EZchip */ ".gnu.lto*", ".discard.*", + ".llvm.call-graph-profile", /* call graph */ NULL }; -- 2.42.0.rc1.204.g551eb34607-goog
