re PR debug/27574 (MIssing debug info at -O0 for a local variable in a C++ constructor)
gcc/ChangeLog:
2008-11-12 Dodji Seketeli <dodji@redhat.com>
PR debug/27574
* cgraph.h: New abstract_and_needed member to struct cgraph_node.
* cgraphunit.c (cgraph_analyze_functions): Flag abstract functions
- which clones are reachable - as "abstract and needed".
* cgraph.c (cgraph_release_function_body): If a node is "abstract and needed",
do not release its DECL_INITIAL() content because that will be needed to emit
debug info.
gcc/testsuite/ChangeLog:
2008-11-12 Dodji Seketeli <dodji@redhat.com>
PR debug/27574
* g++.dg/debug/dwarf2/local-var-in-contructor.C: New test.
