analyzer: detect -Wanalyzer-allocation-size at call stmts [PR106203]
gcc/analyzer/ChangeLog:
PR analyzer/106203
* checker-event.h: Include "analyzer/event-loc-info.h".
(struct event_loc_info): Move to its own header file.
* diagnostic-manager.cc
(diagnostic_manager::emit_saved_diagnostic): Move creation of
event_loc_info here from add_final_event, and if we have a
stmt_finder, call its update_event_loc_info method.
* engine.cc (leak_stmt_finder::update_event_loc_info): New.
(exploded_node::detect_leaks): Likewise.
(exploded_node::detect_leaks): Pass nullptr as call_stmt arg to
region_model::pop_frame.
* event-loc-info.h: New file, with content taken from
checker-event.h.
* exploded-graph.h (stmt_finder::update_event_loc_info): New pure
virtual function.
* infinite-loop.cc (infinite_loop_diagnostic::add_final_event):
Update for change to vfunc signature.
* infinite-recursion.cc
(infinite_recursion_diagnostic::add_final_event): Likewise.
* pending-diagnostic.cc (pending_diagnostic::add_final_event):
Pass in the event_loc_info from the caller, rather than generating
it from a gimple stmt and enode.
* pending-diagnostic.h (pending_diagnostic::add_final_event):
Likewise.
* region-model.cc (region_model::on_longjmp): Pass nullptr as
call_stmt arg to region_model::pop_frame.
(region_model::update_for_return_gcall): Likewise, but pass
call_stmt.
(class caller_context): New.
(region_model::pop_frame): Add "call_stmt" argument. Use it
and the frame_region with a caller_context when setting
result_dst_reg's value so that any diagnostic is reported at the
call stmt in the caller.
(selftest::test_stack_frames): Pass nullptr as call_stmt arg to
region_model::pop_frame.
(selftest::test_alloca): Likewise.
* region-model.h (region_model::pop_frame): Add "call_stmt"
argument.
gcc/testsuite/ChangeLog:
PR analyzer/106203
* c-c++-common/analyzer/allocation-size-1.c (test_9): Remove
xfail.
* c-c++-common/analyzer/allocation-size-2.c (test_8): Likewise.
* gcc.dg/analyzer/allocation-size-multiline-4.c: New test.
* gcc.dg/plugin/analyzer_cpython_plugin.c
(refcnt_stmt_finder::update_event_loc_info): New.
