modified_type_die and add_type_attribute take two separate arguments for whether the type should be const and/or volatile. To help add more type modifiers pass the requested modifiers as one cv_quals argument to these functions. And introduce helper function decl_quals to extract additional cv_quals from declaration trees. DWARFv3 added restrict_type [PR debug/59051] and DWARFv5 has proposals for atomic_type and aligned_type. Which will be easier to implement based on this change. gcc/ChangeLog * dwarf2out.c (decl_quals): New function.

Add a new type:var variant to the guality.exp testsuite to check that gdb gets the correct type for a variable or function. To use it in a guality test add something like: /* { dg-final { gdb-test 50 "type:main" "int (int, char **)" } } */ Which will put a breakpoint at line 50 and check that the type of "main" equals "int (int, char **)" according to gdb. The test harness will make sure to squash all extra whitespace/newlines that gdb might use to make comparisons of large structs easy. gcc/testsuite/ChangeLog * lib/gcc-gdb-test.exp (gdb-test): Handle type:var for gdb ptype matching.
