Undo dynamic symbol state after regular object sym type mismatch We already handle the case of an object file first defining a symbol that a later shared library also defines where the symbol types are incompatible. This patch handles the reverse, when a later object file defines an incompatible symbol defined by an earlier shared library. bfd/ * elflink.c (_bfd_elf_merge_symbol): Undo dynamic linking state when a regular object file defines a symbol with incompatible type to that defined by an earlier shared lib. ld/ * testsuite/ld-elf/indirect5a.c, * testsuite/ld-elf/indirect5b.c, * testsuite/ld-elf/indirect5.map, * testsuite/ld-elf/indirect5.out: New test. * testsuite/ld-elf/indirect6a.c: Likewise. * testsuite/ld-elf/indirect.exp (check_dynamic_syms): New proc. Run new tests and check dynsyms. 2017-04-17 17:03:52 +08:00			`extern void foo (long *);`
