gcc10-pr94029.patch

The problem is that C FE finish_function uses input_location as
cfun->function_end_locus, but input_location isn't really updated very ofte=
n in
the C FE anymore, mostly in the line change hooks but that doesn't trigger =
here
because the macro arguments span across newline.
So, either like in the completely untested patch we can update input_locati=
on
somewhat more often, or we'd need to propagate the location_t of the closin=
g }
from c_parser_compound_statement_nostart to the callers.=
