Hi.
There's one another ICE when calling fn_summary->get for a node
that's not present. Back-trace is:
(gdb) bt
#0 inline_to_all_callers (node=<cgraph_node * 0x7ffff698f5a0 "*.LTHUNK0"/2>,
data=0x7fffffffd690) at /home/marxin/Programming/gcc/gcc/ipa-inline.c:2260

The problematic symbol is:
(gdb) p node
$1 = <cgraph_node * 0x7ffff698f5a0 "*.LTHUNK0"/2>
(gdb) p node->debug()
*.LTHUNK0/2 (int B::*.LTHUNK0(int, int)) @0x7ffff698f5a0
Type: function definition analyzed alias cpp_implicit_alias
Visibility: prevailing_def_ironly artificial
References: _ZN1B1aEii/1 (alias)
Referring:
Availability: available
First run: 0
Function flags:
Called by: virtual int B::_ZTv0_n24_N1B1aEii(int, int)/3 (can throw external)
Calls:
Hope it's fine to use get_create and let the symbol be inlined?
Patch survives tests on x86_64-linux-gnu.
Ready for trunk?

* ipa-inline.c (inline_to_all_callers_1): Use ::get_create
at place where we can have a function that's not
in summary.
