* elf32-arm.c (elf32_arm_check_relocs): Use call_reloc_p, may_need_local_target_p and may_become_dynamic_p to classify the relocation type. Don't check info->symbolic or h->def_regular when deciding whether to record a potential dynamic reloc. Don't treat potential dynamic relocs as PLT references. (elf32_arm_gc_sweep_hook): Update to match. Assert that we don't try to make the PLT reference count go negative. ld/testsuite/ * ld-arm/arm-lib-plt-2a.s, ld-arm/arm-lib-plt-2b.s, ld-arm/arm-lib-plt-2.dd, ld-arm/arm-lib-plt-2.rd: New tests. * ld-arm/arm-elf.exp: Run them.
