Have the assembler prepare for linker relaxation by default. This
means that users will be able to make use of linker relaxation without
having to adjust the assembler flags, this can make life easier when
compiling libraries.
Having this on by default in the assembler should make no difference to
the assembler code produced, however, some of the debug information will
be slightly less compressed.
A few tests needed to be updated as a result of this change as they
relied on linker relaxation support being off by default.
I've tightened up the definition of which sections can be relaxed on AVR
as part of this commit, the assembler used to think that all
non-debugging sections could be relaxed, when in reality only code
sections can be relaxed for AVR. The previous definition was not
dangerous, just over cautious. The new tighter definition allows an
extra test (gas/testsuite/gas/all/forward.d) to continue to pass.
gas/ChangeLog:
* config/tc-avr.c (struct avr_opt_s): Change link_relax to
no_link_relax, extend comment.

The AVR target uses a bit in the elf header flags to indicate if the
object was assembled ready for linker relaxation. Previously this flag
was always set, even when the object was not assembled ready for linker
relaxation.
This patch moves setting of the flag into the assembler, and sets it
only when the assembler is preparing the file for linker relaxation.

For conditional branches that need more than one trampoline to reach its
target assembler couldn't always find suitable trampoline because
post-loop condition check was placed inside the loop, resulting in
premature loop termination. Move check outside the loop.
This fixes the following build errors seen when assembling huge files
produced by gcc:
Error: jump target out of range; no usable trampoline found
Error: operand 1 of 'j' has out of range value '307307'

The construct being added to the cond.s test case otherwise triggered

support (include) files that can be used for both assembler .include
and compiler #include directives.
The write.c change is to make gas report an error if reg_section
symbols should leak in future. The tc-i386.c change is the real fix.
Note that the error isn't the most helpful, "redefined symbol cannot
be used on reloc", but I'm not inclined to improve what is really an
internal gas error. reg_section symbols shouldn't leak..

form arch@testname.l .

(ISA_MIPS32R6): New define.
(ISA_MIPS64R6): New define.
(CPU_MIPS32R6): New define.
(CPU_MIPS64R6): New define.
(cpu_is_member): Add cases for CPU_MIPS32R6, and CPU_MIPS64R6.
ld/
* ldmain.c (get_emulation): Add support for -mips32r6 and -mips64r6.
opcodes/
* mips-dis.c (mips_arch_choices): Add entries for mips32r6 and
mips64r6.
(parse_mips_dis_option): Allow MSA and virtualization support for
mips64r6.
(mips_print_arg_state): Add fields dest_regno and seen_dest.
(mips_seen_register): New function.
(print_insn_arg): Refactored code to use mips_seen_register
function. Add support for OP_SAME_RS_RT, OP_CHECK_PREV and
OP_NON_ZERO_REG. Changed OP_REPEAT_DEST_REG case to print out
the register rather than aborting.
(print_insn_args): Add length argument. Add code to correctly
calculate the instruction address for pc relative instructions.
(validate_insn_args): New static function.
(print_insn_mips): Prevent jalx disassembling for r6. Use
validate_insn_args.
(print_insn_micromips): Use validate_insn_args.
all the arguments are valid.
* mips-formats.h (PREV_CHECK): New define.
* mips-opc.c (decode_mips_operand): Add support for -a, -b, -d, -s,
-t, -u, -v, -w, -x, -y, -A, -B, +I, +O, +R, +:, +\, +", +;
(RD_pc): New define.
(FS): New define.
(I37): New define.
(I69): New define.
(mips_builtin_opcodes): Add MIPS R6 instructions. Exclude recoded
MIPS R6 instructions from MIPS R2 instructions.
gas/
* config/tc-arm.c (aeabi_set_public_attributes): Update intended_arch based
on the info we got during parsing.
(arm_handle_align): Make sure the p2align expanding logic under thumb
unchanged.

opcodes/
* arm-dis.c (print_arm_address): Negate the GPR-relative offset
returned if the U bit is set.
2014-08-21 Paul Brook <paul@codesourcery.com>
gas/testsuite/
* gas/arm/arch7a-mp.d: Adjust according to `print_arm_address'
offset fix.
* gas/arm/arch7r-mp.d: Likewise.
