Severity: normal

Target Milestone: ---
Hi GCC developers,
When I use Linaro GCC 7.2-2017.11 arm-linux-gnueabihf cross-compile
toolchain[1] to build L4Re and L4Linux[2]
Toolchain thrown such error:
/data/project/xiangzhai/l4re/l4/pkg/io/io/server/src/virt/vmsi.cc:28:1:
internal compiler error: in gimple_get_virt_method_for_vtable, at
gimple-fold.c:6467
}
^
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://gcc.gnu.org/bugs/> for instructions.
l4re/l4/pkg/io/io/server/src/virt/vmsi.cc:28 define a static variable in an
anonymous namespace[3]
26 namespace {
27 static Vi::Resource_factory_t<Vi::Msi_resource, Hw::Msi_resource>
__vmsifactory;
28 }
Linaro gcc-7.2.1/gcc/gimple-fold.c:6467 call gcc_assert[4]
6460 /* The virtual tables should always be born with constructors
6461 and we always should assume that they are avaialble for
6462 folding. At the moment we do not stream them in all cases,
6463 but it should never happen that ctor seem unreachable. */
6464 gcc_assert (init);
6465 if (init == error_mark_node)
6466 {
6467 gcc_assert (in_lto_p);
6468 /* Pass down that we lost track of the target. */
6469 if (can_refer)
6470 *can_refer = false;
6471 return NULL_TREE;
6472 }
I have no idea why `in_lto_p` is NULL?
Please give me some suggestion, thanks a lot!
