For a program compiled with gfortran the base type names are written as lower cases in the DWARF, and so GDB will display them as lower case. Additionally, in most places where GDB supplies its own type names (for example all of the types defined in f-lang.c in `build_fortran_types`), the type names are all lower case. An exception to this is where GDB prints the void type for Fortran. In this case GDB uses upper case. I'm not aware of any reason why this type should merit special attention, and it looks our of place when printing types, so this commit changes from 'VOID' to 'void' to match all the other types. gdb/ChangeLog: * f-lang.c (build_fortran_types): Change name of void type to lower case. * f-typeprint.c (f_type_print_base): Print the name of the void type, rather than a fixed string. * f-valprint.c (f_decorations): Use lower case void string. gdb/testsuite/ChangeLog: * gdb.fortran/exprs.exp (test_convenience_variables): Expect lower case void string.
