Fortran: Testsuite, non-local references in nested functions.
Non-local references in nested functions are usually implemented
by using DWARF static link. This feature was added
with commit 63e43d3aedb8b1112899c2d0ad74cbbee687e5d6
(DWARF: handle non-local references in nested functions) but
a testcase was missing in Fortran.
2016-06-10 Bernhard Heckel <bernhard.heckel@intel.com>
gdb/Testsuite/Changelog:
* gdb.fortran/nested-funcs.exp: New.
* gdb.fortran/nested-funcs.f90: New.
