Hi, I have problems compiling xalan as part of spec2006 benchmark for aarch64, both native and cross. The issue arises when both -flto and -fprofile-generate are enabled during LTO. Compiling with the same flags for x86 has no problem. Also other projects for aarch64 compile with -flto and -fprofile-generate without problem.
lto1: internal compiler error: in add_symbol_to_partition_1, at
lto/lto-partition.c:210
204 /* Ensure that SAME_COMDAT_GROUP lists all allways added in a group. */
205 if (node->same_comdat_group)
206 for (node1 = node->same_comdat_group;
207 node1 != node; node1 = node1->same_comdat_group)
208 if (!node->alias)
209 {
210 bool added = add_symbol_to_partition_1 (part, node1);
211 gcc_assert (added);
212 }
213 return true;
214 }
Is this a known issue? How can I debug this? Do I need additional options?
Any hints?
I get this error:
