--- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
This should be easy with track macro expansion on, we'd just have
--- a/gcc/input.h
+++ b/gcc/input.h
@@ -60,6 +60,8 @@ extern location_t input_location;
#define in_system_header_at(LOC) \
((linemap_location_in_system_header_p (line_table, LOC)))
+#define from_macro_expansion_at(LOC) \
+ ((linemap_location_from_macro_expansion_p (line_table, LOC)))
void dump_line_table_statistics (void);
and then we could use from_macro_expansion_at and don't warn if it's true. But
the problem is with -ftrack-macro-expansion=0, since from_macro_expansion_at
wouldn't work :(.
