PR ld/21900: MIPS: Fix relocation processing with undefined symbols Currently, when `mips_elf_calculate_relocation' is asked to relocate an undefined symbol, it reports an error or a warning and immediately returns without performing the relocation. This is fine if the link fails, but if unresolved_syms_in_objects == RM_GENERATE_WARNING, the link will continue and output some unrelocated code, which is a regression from commit e7e2196da3f0 ("MIPS/BFD: Correctly report undefined relocations"). Fix this by continuing after calling the `undefined_symbol' hook unless this is an error condition. bfd/ PR ld/21900 * elfxx-mips.c (mips_elf_calculate_relocation): Only return after calling `undefined_symbol' hook if this is an error condition. Assume the value of 0 for the symbol requested otherwise. ld/ PR ld/21900 * testsuite/ld-mips-elf/undefined-warn.d: New test. * testsuite/ld-mips-elf/undefined.s: Add padding at the end. * testsuite/ld-mips-elf/mips-elf.exp: Run the new test. 2018-03-03 23:49:21 +08:00			`#objdump: -d --prefix-addresses --show-raw-insn`
