Hello,
these patches correct diagnostics dealing with variables in specification
expressions.
The first patch is a testsuite change, which fixes invalid specification
expressions that the second patch would diagnose.
The second patch removes a spurious diagnostic when a dummy procedure is
involved, and enables more valid ones, as visible in the testcases from the
first patch.
The patch is not completely trivial, and fix what is not really a regression,
so it is more for stage1, I think.
Tested for regression on x86_64-pc-linux-gnu. Ok for master when stage1
opens?

This fixes a spurious invalid variable in specification expression error.
The problem is caused by improper restoration of formal_arg_flag to false
(instead of restoring it to its previous value). This happens with the
testcase from the PR where a dummy argument is itself a procedure with dummy
arguments. At the time that dummy procedure has been resolved, its dummy
arguments have been resolved and the flag has been reset to false. The
condition checking that flag when resolving the array spec expressions of
the next dummy then triggers the error.
The fix removes a condition disabling proper check of specification
expressions, together with the formal_arg_flag global variable associated
with it. As the specification expression checking code is dependent on the
current namespace, the latter is set before array spec resolution (and
restored after). Two new functions are introduced to select the right
namespace for that.
PR fortran/111781
gcc/fortran/ChangeLog:
* symbol.cc (gfc_get_procedure_ns, gfc_get_spec_ns): New functions.
* gfortran.h (gfc_get_procedure_ns, gfc_get_spec ns): Declare them.
(gfc_is_formal_arg): Remove.
* expr.cc (check_restricted): Remove the case where symbol is dummy
and declared in the current ns. Use gfc_get_spec_ns to get the
right namespace.
* resolve.cc (gfc_is_formal_arg, formal_arg_flag): Remove.
(gfc_resolve_formal_arglist): Set gfc_current_ns. Quit loop and
restore gfc_current_ns instead of early returning.
(resolve_symbol): Factor common array spec resolution code to...
(resolve_symbol_array_spec): ... this new function. Additionnally
set and restore gfc_current_ns.
gcc/testsuite/ChangeLog:
* gfortran.dg/spec_expr_8.f90: New test.
* gfortran.dg/spec_expr_9.f90: New test.
