Decl_uid is re-assigned during LTO streaming and thus still unique.

How can distinguish DECL in LTO mode?

Hello, everyone.
Sorry to disturb you, but this question confused me several days, I have
searched the GCC source code cannot find the answers.

I know we can distinguish the different DECL tree using DECL_UID in a
translation unit. But when in LTO mode, lto1 combine some input fat object
files. How can I distinguish the different DECL tree may come from
two different object files?

Thanks.
