bfd/ * elf32-arm.c (elf32_arm_final_link_relocate): Don't convert ARM branch to an undef weak symbol into a jump to next instruction if a PLT entry will be created. testsuite/ * ld-arm/arm-elf.exp: Add 1 more test to check undef weak reference with PLT in ARM mode. * ld-arm/thumb2-bl-undefweak1.d, ld-arm/thumb2-bl-undefweak1.s: New files.
