ef5a96d564 Remove ppc860, ppc750cl, ppc7450 insns from common ppc.
Back in the day support for these processors was added, we probably
didn't want to waste PPC_OPCODE bits on minor variations.  I've had a
complaint that disassembly of mfspr/mtspr was wrong for power8.  This
patch fixes that problem.

Note that since -m860/-m850/-m821 are new gas options enabling the
mpc8xx specific mfspr/mtspr variants it is possible that this change
will break some mpc8xx assembly code.  ie. you might need to modify
makefiles to pass -m860 to gas.

include/opcode/
	* ppc.h (PPC_OPCODE_750, PPC_OPCODE_7450, PPC_OPCODE_860): Define.
opcodes/
	* ppc-opc.c (PPC750, PPC7450, PPC860): Define using PPC_OPCODE_*.
	* ppc-dis.c (ppc_opts): Add 821, 850 and 860 entries.  Add
	PPC_OPCODE_7450 to 7450 entry.  Add PPC_OPCODE_750 to 750cl entry.
gas/
	* config/tc-ppc.c (md_show_usage): Add -m821, -m850, -m860.
	* doc/c-ppc.texi (PowerPC-Opts): Likewise.

ef10c3ace0 Use strtab with GC and suffix merging for .strtab
This patch uses ELF strtab with GC and suffix merging support to create
ELF .strtab section.  There is some small memory overhead to use ELF
strtab:

It reduces the .strtab size by 350 bytes, about 2%

Saving on libc.so from glibc is much more since libc.so has many alias
symbols with the same suffix.  For x32 glibc,

 [82] .strtab STRTAB 0+ 81b348 0159e7 00 0 0 1

support for this insruction varient here:

    https://sourceware.org/ml/binutils/2012-02/msg00221.html

Looking at this closer, I see that the insert_ls() function is misnamed
(since it's attached to the ESYNC operand, not the LS operand) but more
importantly, it is silently modifying the LS operand value behind the
users back when the LS operand is either invalid or is incompatible with
the new ESYNC operand.  The ISA 2.07 doc has an Assembler Note that clearly
states that assemblers that support the ESYNC operand should report all
invalid uses of LS and ESYNC.  This patch changes the assembler to
error out on invalid and incompatible operand usage.

11a0cf2ec0 Allow for optional operands with non-zero default values.
ISA 2.07 (ie, POWER8) added the rfebb instruction which takes one operand
with the value of either a 0 or 1.  It also defines an extended mnemonic
with no operands (ie, "rfebb") that is supposed to be equivalent to "rfebb 1".
I implemented rfebb's lone operand with PPC_OPERAND_OPTIONAL, but the
problem is, optional operands that are ommitted always default to the
value 0, which is wrong in this case.  I have added support for allowing
non-zero default values by adding an additional flag PPC_OPERAND_OPTIONAL_VALUE
that specifies that the default operand value to be used is stored in the
SHIFT field of the operand field immediately following this one.

This fixes the rfebb issue.  I also fixed the mftb and mfcr instructions
so they use the same mechanism.  This allows us to flag invalid uses of
mfcr where we explicitly pass in a zero FXM value, like the use in a2.[sd].

d025d5e5b5 gas: Don't use frag_align but use plain padding to align .debug_aranges.
out_debug_aranges uses frag_align to make sure the addresses start
out aligned. Using frag_align will call frag_var[_init], which will
end up calling TC_FRAG_INIT. On arm and aarch64 TC_FRAG_INIT will
generate a $d mapping symbol for the .debug_aranges to show that at
that point a sequence of data items starts.

Such a symbol pointing into a non-allocated debug section will confuse
eu-strip -g. And it seems inefficient and wrong in general to have
additional mapping symbols for debug sections, which won't contain
actual code in the first place.

Just keep track of the aranges header size and use plain padding to
align the addresses which avoids generating any mapping symbols on
aarch64 and arm.

Includes a testcase for aarch64 that PASS with this patch and shows
the extra $d mapping symbol in .debug_aranges before.

dc302c0061 Add hwsync extended mnemonic.
This commit adds a new extended menmonic for "sync 0" (same as "sync").
The ISA documentation doesn't explicitly mention hwsync as an extended

the operation that gets performed when the sync's L field is 0.
This is only enabled for POWER4 and later.

5db04b0965 Support AMD64/Intel ISAs in assembler/disassembler
AMD64 spec and Intel64 spec differ in direct unconditional branches in
64-bit mode.  AMD64 supports direct unconditional branches with 16-bit
offset via the data size prefix, which truncates RIP to 16 bits, while
the data size prefix is ignored by Intel64.

This patch adds -mamd64/-mintel64 option to x86-64 assembler and
-Mamd64/-Mintel64 option to x86-64 disassembler.  The most permissive
ISA, which is AMD64, is the default.

GDB can add an option, similar to

(gdb) help set disassembly-flavor
Set the disassembly flavor.
The valid values are "att" and "intel", and the default value is "att".

to select which ISA to disassemble.

8dcea93252 Add -mshared option to x86 ELF assembler
This patch adds -mshared option to x86 ELF assembler.  By default,
assembler will optimize out non-PLT relocations against defined non-weak
global branch targets with default visibility.  The -mshared option tells
the assembler to generate code which may go into a shared library
where all non-weak global branch targets with default visibility can
be preempted.  The resulting code is slightly bigger.  This option
only affects the handling of branch instructions.

This Linux kernel patch is needed to create a working x86 Linux kernel if
it hasn't been applied:

dc58915f3a xtensa: fix gas trampolines regression
Extra condition 'abs (addr - trampaddr) < J_RANGE / 2' for trampoline
selection results in regressions: when relaxable jump is little longer
than J_RANGE so that single trampoline makes two new jumps, one longer
than J_RANGE / 2 and one shorter, correct trampoline cannot be found.

Drop that condition.

On ELF target, the assembler normally generates code which can go into a
shared library where non-weak symbols can be preempted.  The -mno-shared

smaller.  This option mainly affects the handling of branch instructions.
