re PR middle-end/41257 (Bogus error '*.LTHUNK0' aliased to undefined symbol '_ZN1CD1Ev')
2009-09-04 Richard Guenther <rguenther@suse.de>
PR middle-end/41257
* (cgraph_finalize_compilation_unit): Move finalizing aliases
after emitting tunks. Move emitting thunks and ctors from ...
(cgraph_optimize): ... here. Remove redundant
cgraph_analyze_functions.
* varasm.c (find_decl_and_mark_needed): Remove no longer
necessary check.
(finish_aliases_1): Adjust check for thunk aliases.
* g++.dg/torture/pr41257.C: New testcase.
