Yes, it's a problem of the linker in my testing environment. I've tried to
manually link it with a different linker, it can run successfully. And the
correct stub is generated

2472 a9c8 gcov_init_from_thumb:
2473 a9c8:   4778bx  pc
2474 a9ca:   46c0nop ; (mov r8, r8)
2475 a9cc:   ea45b   a6e8 __gcov_init

Did you try -fuse-ld=bfd to see if this problem appear in both linkers?

That's a bug in your linker, not in the compiler.
