* arm.h: Import complete list of official relocation names and numbers from AAELF. Define FAKE_RELOCs for old names. Remove a few old names no longer used anywhere. bfd: * elf32-arm.c: Wherever possible, use official reloc names from AAELF. (elf32_arm_howto_table, elf32_arm_tls_gd32_howto) (elf32_arm_tls_ldo32_howto, elf32_arm_tls_ldm32_howto) (elf32_arm_tls_le32_howto, elf32_arm_tls_ie32_howto) (elf32_arm_vtinherit_howto, elf32_arm_vtentry_howto) (elf32_arm_pc11_howto, elf32_arm_thm_pc9_howto, elf32_arm_got_prel) (elf32_arm_r_howto): Replace with elf32_arm_howto_table_1, elf32_arm_howto_table_2, and elf32_arm_howto_table_3. Add many new relocations from AAELF. (elf32_arm_howto_from_type): Update to match. (elf32_arm_reloc_map): Add entries for R_ARM_THM_JUMP24, R_ARM_THM_JUMP11, R_ARM_THM_JUMP19, R_ARM_THM_JUMP8, R_ARM_THM_JUMP6, R_ARM_GNU_VTINHERIT, and R_ARM_GNU_VTENTRY. (elf32_arm_reloc_type_lookup): Use elf32_arm_howto_from_type. (elf32_arm_final_link_relocate): Add support for R_ARM_THM_JUMP24, R_ARM_THM_JUMP19, R_ARM_THM_JUMP6. Remove case entries redundant with default. * reloc.c: Reorganize ARM relocations. Add Thumb assembler-internal relocations BFD_RELOC_ARM_T32_OFFSET_U8, BFD_RELOC_ARM_T32_OFFSET_IMM, BFD_RELOC_ARM_T32_IMMEDIATE. Add visible relocations BFD_RELOC_THUMB_PCREL_BRANCH7, BFD_RELOC_THUMB_BRANCH20, BFD_RELOC_THUMB_BRANCH25. Delete unused relocations BFD_RELOC_ARM_GOT12, BFD_RELOC_ARM_COPY. * bfd-in2.h, libbfd.h: Regenerate. opcodes: * arm-dis.c (thumb_opcodes): Add disassembly for V6T2 16-bit instructions. Adjust disassembly of some opcodes to match unified syntax. (thumb32_opcodes): New table. (print_insn_thumb): Rename print_insn_thumb16; don't handle two-halfword branches here. (print_insn_thumb32): New function. (print_insn): Choose among print_insn_arm, print_insn_thumb16, and print_insn_thumb32. Be consistent about order of halfwords when printing 32-bit instructions. gas: * hash.c (hash_lookup): Add len parameter. All callers changed. (hash_find_n): New interface. * hash.h: Prototype hash_find_n. * sb.c: Include as.h. (scrub_from_sb, sb_to_scrub, scrub_position): New statics. (sb_scrub_and_add_sb): New interface. * sb.h: Prototype sb_scrub_and_add_sb. * input-scrub.c (input_scrub_include_sb): Use sb_scrub_and_add_sb. * config/tc-arm.h (TC_FORCE_RELOCATION_LOCAL): Remove reference to BFD_RELOC_ARM_GOT12 which is never generated. * config/tc-arm.c: Rewrite, adding Thumb-2 support. gas/testsuite: * gas/arm/arm.exp: Convert all existing "gas_test" tests to "run_dump_test" tests. Run more tests unconditionally. Run new tests. * gas/arm/arch4t.s, gas/arm/arch6zk.s, gas/arm/arm3.s, gas/arm/arm6.s * gas/arm/arm7dm.s, gas/arm/bignum1.s, gas/arm/float.s * gas/arm/immed.s, gas/arm/iwmmxt.s, gas/arm/offset.s, gas/arm/thumb.s: Adjust to work as a dump test. * gas/arm/arch4t.d, gas/arm/arch6zk.d, gas/arm/arm3.d, gas/arm/arm6.d * gas/arm/arm7dm.d, gas/arm/bignum1.d, gas/arm/float.d * gas/arm/immed.d, gas/arm/iwmmxt.d, gas/arm/offset.d, gas/arm/thumb.d: New files. * gas/arm/armv1-bad.l, gas/arm/armv1-bad.s: Remove tests for diagnostics that don't happen in the first pass anymore. * gas/arm/iwmmxt-bad.l, gas/arm/r15-bad.l, gas/arm/req.l * gas/arm/vfp-bad.l: Update expected diagnostics. * gas/arm/pic.d: Update expected reloc name. * gas/arm/thumbv6.d: CPY no longer appears in disassembly. * gas/arm/r15-bad.s: Avoid two-argument mul. * gas/arm/req.s: Adjust comments. * gas/arm/maverick.d, gas/arm/maverick.s: Avoid inappropriate use of PC. * gas/arm/macro-1.d, gas/arm/macro1.s * gas/arm/t16-bad.l, gas/arm/t16-bad.s * gas/arm/tcompat.d, gas/arm/tcompat.s * gas/arm/tcompat2.d, gas/arm/tcompat2.s * gas/arm/thumb32.d, gas/arm/thumb32.s New test pair. ld/testsuite: * ld-arm/mixed-app.d: Adjust expected disassembly a little.
