re PR debug/37410 (DW_TAG_imported_module is not in its DW_TAG_lexical_block)
2008-09-30 Dodji Seketeli <dodji@redhat.com>
gcc/ChangeLog:
PR c++/37410
* dwarf2out.c (dwarf2out_imported_module_or_decl): Split this
function in two, making it call a new and reusable
dwarf2out_imported_module_or_decl() that takes the containing
BLOCK of the declaration in argument.
(dwarf2out_imported_module_or_decl_real): New function.
(decls_for_scope, gen_decl_die, dwarf2out_decl): Take
IMPORTED_DECL in account.
* tree.def: Added IMPORTED_DECL node type.
* tree.h: Added accessors for IMPORTED_DECL nodes.
* tree.c (init_ttree): Initialise IMPORTED_DECL node type.
gcc/cp/ChangeLog:
PR c++/37410
* cp-gimplify.c (cp_gimplify_expr): For each USING_STMT
make sure an IMPORTED_DECL node is added to the BLOCK_VARS list
of the innermost containing BLOCK.
gcc/testsuite/ChangeLog:
PR c++/37410
* g++.dg/debug/dwarf2/imported-module.C: New test.
