case SYMBOL_TLSLE: - asm_fprintf (asm_out_file, ":tprel_lo12_nc:"); + if (aarch64_tls_size <= 12) + /* Make sure TLS offset fit into 12bit. */ + asm_fprintf (asm_out_file, ":tprel_lo12:"); + else + asm_fprintf (asm_out_file, ":tprel_lo12_nc:"); break; Use the existing classify_symbol mechanism we use throughout the aarch64 backend. Specifically rename SYMBOL_TLSLE as SYMBOL_TLSLE24 and introduce the 3 missing flavours then use the symbol classification to control behaviour such as this modifier selection. Cheers /Marcus
