When re-testing lazy building of comp_unit_die I noticed that g++.dg/debug/dwarf2/typedef4.C starts to fail. Which is because with that patch we now emit a DIE for 'bool'. The funny thing is that we didn't do so before because the C++ FE calls debug_hooks->type_decl via #0 dwarf2out_decl (decl=0x7ffff7edea10) at /space/rguenther/src/svn/trunk/gcc/dwarf2out.c:20931 #1 0x000000000091d1ab in dwarf2out_type_decl (decl=0x7ffff7edea10, local=0) at /space/rguenther/src/svn/trunk/gcc/dwarf2out.c:20794 #2 0x00000000004e796f in record_builtin_type (rid_index=RID_INT, name=0x0, type=0x7ffff7ee8498) at /space/rguenther/src/svn/trunk/gcc/cp/decl.c:3280 #3 0x00000000007b6308 in c_common_nodes_and_builtins () at /space/rguenther/src/svn/trunk/gcc/c-family/c-common.c:4483 #4 0x00000000004e7fd9 in cxx_init_decl_processing () at /space/rguenther/src/svn/trunk/gcc/cp/decl.c:3436 #5 0x000000000063b970 in cxx_init () at /space/rguenther/src/svn/trunk/gcc/cp/lex.c:252 #6 0x0000000000c50284 in lang_dependent_init ( name=0x7fffffffe15b "/space/rguenther/src/svn/trunk/gcc/testsuite/g++.dg/debug/dwarf2/typedef4.C") at /space/rguenther/src/svn/trunk/gcc/toplev.c:2262 #7 0x0000000000c504b0 in do_compile () at /space/rguenther/src/svn/trunk/gcc/toplev.c:2393 which happens before(!) debug_hooks->init is called. Which of course leaves comp_unit_die NULL and thus is_cxx () return false. Huh. So to avoid regressing g++.dg/debug/dwarf2/typedef4.C this patch removes that bool special-case as it obviously didn't work anyways if bool wasn't used in the TU. What to do with the above initialization order problem I have no idea (maybe move debug_hooks->init before lang_hooks.init ()?). Bootstrapped on x86_64-unknown-linux-gnu, testing in progress. Ok for trunk? Thanks, Richard. 2010-09-21 Richard Guenther <rguenther@suse.de> * dwarf2out.c (dwarf2out_decl): Do not always generate a DIE for bool for C++.
