2016-08-12[PR55641] drop spurious const_type from reference_type variablesAlexandre Oliva4-0/+30
Although C++ reference types, denoted by DW_TAG_reference_type in DWARFv2+ debug info, are unchangeable, we output names of reference type with DW_TAG_const_type, because internally we mark such variables as TREE_READONLY. That's an internal implementation detail that shouldn't leak to debug information. This patch fixes this. for gcc/ChangeLog PR debug/55641 * dwarf2out.c (decl_quals): Don't map TREE_READONLY to TYPE_QUAL_CONST in reference-typed decls. for gcc/testsuite/ChangeLog PR debug/55641 * g++.dg/debug/dwarf2/ref-1.C: New.

2016-08-12[PR49366] emit loc exprs for C++ non-virtual pmf template value parmsAlexandre Oliva11-1/+181
We used to emit, in debug information, the values bound to pointer to member function template parameters only when they were NULL or virtual member functions, because those can be represented with DW_AT_const_value. In order to represent the symbolic pointer to member function constants for non-virtual member functions, we'd need to be able to emit relocations for part of DW_AT_const_value, which we don't. The more viable alternative is to use DW_AT_location to represent such values, as slated for inclusion in DWARFv5, according to <URL:http://www.dwarfstd.org/ShowIssue.php?issue=130412.1>. With this patch, when we can't emit a DW_AT_const_value, we emit each "member" of the pointer to member function "record" as a DW_OP_stack_value DW_OP_piece, as long as the referenced member function is output in the same translation unit, otherwise we'd get relocations to external symbols, something to avoid in debug sections. for gcc/ChangeLog PR debug/49366 * dwarf2out.c (loc_list_from_tree_1): Expand some CONSTRUCTORs in DW_OP_pieces, just enough to handle pointers to member functions.
