--- Comment #40 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I must say I don't like -fbroken-callers option name too much, can we use
instead something like -ftail-call-workaround={0,1,2} /
-f{,no-}tail-call-workaround
where -ftail-call-workaround == -ftail-call-workaround=1 would be the default
(for now) and enabled only if resolve_symbol finds FL_PROCEDURE if_source ==
IFSRC_UNKNOWN symbols (remembered in some gfc_ns member and set on containing
procedure, not say containing BLOCK), -fno-tail-call-workaround ==
-ftail-call-workaround=0 would disable this and -ftail-call-workaround=2 would
be enabled no matter whether there are any FL_PROCEDURE IFSRC_UNKNOWN symbols
or not?
