These 2 are used for the kernel and the lack of a declaration is causing problems. So add the declarations for these 2 builtins. At the same time also add one for '__builtin_custom_ini()' since this one may also be used in the kernel. Note: a better fix should be to move this to target-nios2.c Link: https://lore.kernel.org/lkml/20200609151329.GU23011@xsang-OptiPlex-9020/ Reported-by: kbuild test robot <lkp@xxxxxxxxx> Signed-off-by: Luc Van Oostenryck <luc.vanoostenryck@xxxxxxxxx> --- builtin.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/builtin.c b/builtin.c index debc22c036ec..5ed17700d422 100644 --- a/builtin.c +++ b/builtin.c @@ -613,4 +613,9 @@ void declare_builtins(void) declare_builtin("__builtin_bfin_csync", &void_ctype, 0, NULL); declare_builtin("__builtin_bfin_ssync", &void_ctype, 0, NULL); declare_builtin("__builtin_bfin_norm_fr1x32", &int_ctype, 0, &int_ctype, NULL); + + // Nios-II-specific + declare_builtin("__builtin_rdctl", &int_ctype, 0, &int_ctype, NULL); + declare_builtin("__builtin_wrctl", &void_ctype, 0, &int_ctype, &int_ctype, NULL); + declare_builtin("__builtin_custom_ini", &int_ctype, 0, &int_ctype, NULL); } -- 2.27.0
