dn_table, mav_mvf_table, mac_mvd_table, mav_mvfx_table,
mav_mvax_table, mav_dspc_table): Initialise new field.
(insert_reg_alias): Initialise new field.
(md_pseudo_table): Add "unreq" entry.
(s_unreq): New function: Undo the effects of a previous .req.
* doc/c-arm.texi: Document new pseudo op.
* NEWS: Mention new feature.
* testsuite/gas/arm/req.s: New test file. Check .req and .unreq psuedo ops.
* testsuite/gas/arm/req.l: Expected error output from req.s test.
* testsuite/gas/arm/copro.d: Set target architecture for objdump so that the
test will work on architectures which cannot encode higher arm architecture
types in their file headers.
* testsuite/gas/arm/arm.exp: Run new req.s test.
Skip thumb instruction test for PE targets which do not support
thumb relocations.
* testsuite/gas/elf/elf.exp: Skip special handling of section2 test for XScale
targets - it is no longer needed.
* config/tc-arm.c (ARM_CEXT_XSCALE): Replaces ARM_EXT_XSCALE. All
uses changed.
(ARM_CEXT_MAVERICK): Similarly.
(ARM_ANY): Now means any core instruction.
(CPU_DEFAULT): Default to ARM_ANY.
(uses_apcs_26, atcps, support_interwork, uses_apcs_float)
(pic_code): Declare for all object types. Make type int.
(legacy_cpu, legacy_fpu, mcpu_cpu_opt, mcpu_fpu_opt, march_cpu_opt)
(march_fpu_opt, mfpu_opt): Declare.
(md_longopts): Tidy up conditional definitions.
(arm_opts, arm_cpus, arm_archs, arm_fpus, arm_extensions)
(arm_long_opts): New tables.
(arm_parse_cpu, arm_parse_arch, arm_parse_fpu): New functions.
(arm_parse_extension): New function.
(md_parse_option): Rewrite using new table-driven system.
(md_show_usage): Use new table-driven system.
(md_begin): Calculate cpu_variant from command line option data.
* doc/as.texinfo (ARM ISA options): Docuement new ARM-specific
command-line options.
* doc/c-arm.texi: Likewise.
Testsuite:
* gas/arm/vfp1.d: Use new command-line options.
* gas/arm/vfp1xD.d: Likewise.
* gas/arm/arm.exp (vfp-bad): Likewise.
* gas/arm/maverick.d: Likewise.
* doc/as.texinfo: Fix spelling and cross-references.
* doc/c-arm.texi: Fix typos. Say that `;' is a line separator
character for all systems, not just GNU/Linux. Make it explicit
that `-k' doesn't affect code generation, just ELF flags.
