Re: [patch, fortran] PR24784, PR28004 - about unused variables

Depending on the command-line arguments -Wall and -Wextra, gfortran gives different kinds of warnings for unused dummy arguments. In addition, sometimes the middle-end chimes in and emits a default warning as well (PR27484). Further, PR28004 requests a warning if dummy arguments of INTENT(out) are not set.

This patch addresses all this in a single sweep, the corrected warnings are
emitted on -Wall regardless of -Wextra (via warn_unused_variable). The
changes should be self explanatory, those in function.c probably need to be
approved by a C- or global maintainer?!

The function.c bits are ok. But you need a bootstrap & regtest for all default
languages if you touch a middle-end part, so please make sure that there are
no regressions for those.


Thanks,
Richard.
After Richards request, Fortran side is OK as well.
