As GCC often creates new attributes, generaly for specific usages irrelevant to what sparse is used for. The errors from these not-yet-known attributes create needless noise and annoyance for no benefits. This series aims at reduce this noise by doing 3 things: * change the error to a warning * add a new flag to disable or enable warnings from those attributes * by default set this flag as disabled Change from v1: - compile fix for a patch splitting leftover - each patch depends on the previous one Luc Van Oostenryck (3): Warn on unknown attributes instead of throwing errors Add a new warning flag: '-Wunknown-attribute' By default disable the new warning flag '-Wunknown-attribute' lib.c | 2 ++ lib.h | 1 + parse.c | 3 ++- validation/Wunknown-attribute-def.c | 8 ++++++++ validation/Wunknown-attribute-no.c | 9 +++++++++ validation/Wunknown-attribute-yes.c | 10 ++++++++++ 6 files changed, 32 insertions(+), 1 deletion(-) create mode 100644 validation/Wunknown-attribute-def.c create mode 100644 validation/Wunknown-attribute-no.c create mode 100644 validation/Wunknown-attribute-yes.c -- 2.10.1
