a47622ac1b Allow both signed and unsigned fields in PowerPC cmpli insn
There are legitimate reasons to allow a signed value in a cmpli insn
field, for example to test for a "stw r1,lock@sdarel(r13)" instruction
in user code, a kernel might use
	subis r3,r3,STW_R1_0R13@ha	# subtract off high part
	cmplwi r3,lock@sdarel		# is low part accessing lock?
Since the lock@sdarel may take a range of -32768 to 32767,
the allowed range of cmpli immediate must be at least [-32768,65535].

	insn as a bitfield; Use complain_overflow_bitfield.

397998fc32 Support fusion for ELFv2 stubs
Power8 fuses addis,addi and addis,ld sequences when the target of the
addis is the same as the addi/ld.  Thus
    addis r12,r2,xxx@ha
    addi r12,r12,xxx@l / ld r12,xxx@l(r12)
is faster than
    addis r11,r2,xxx@ha
    addi r12,r11,xxx@l / ld r12,xxx@l(r11)
So use the form that allows fusion in plt call and branch stubs.

f6c7c3e8b7 Referencing a function's address on PowerPC64 ELFv2
ELFv2 needs to create plt entries in a non-PIC executable for an
address reference to a function defined in a shared object.  It's
possible that an object file has no features that distinguish it as
ELFv1 or ELFv2, eg. an object only containing data.  Such files need
to be handled like those that are known to be ELFv2.
However, this unnecessarily creates plt entries for the analogous
ELFv1 case, so arrange to set output abi version earlier, and use the
output abi version to further distinguish ambiguous input files.

bfd/
	* elf64-ppc.c (ppc64_elf_check_relocs): Account for possibly
	needed plt entries when taking the address of functions for
	abiversion == 0 (ie. unknown) as well as abiversion == 2.

	ppc64_elf_process_dot_syms.  Set output abiversion from input and
	input abiversion from output, if either is not set.

b80eed39e2 Better overflow checking for powerpc64 relocations
R_PPC64_ADDR16 is used in three contexts:
- .short data relocation
- 16-bit signed insn fields, eg. addi
- 16-bit unsigned insn fields, eg. ori
In the first case we want to allow both signed and unsigned 16-bit
values, the latter two ought to error if the field exceeds the range
of values allowed for 16-bit signed and unsigned integers
respectively.  These conflicting requirements meant that ld had to
choose the least restrictive overflow checks, and thus it is possible
to construct testcases where an addi field overflows but is not
reported by ld.  Many relocations dealing with 16-bit insn fields have
this problem.  What's more, some relocations that are only ever used
for signed fields of instructions woodenly copied the lax overflow
checking of R_PPC64_ADDR16.

bfd/
	* elf64-ppc.c (ppc64_elf_howto_raw): Use complain_overflow_signed
	for R_PPC64_ADDR14, R_PPC64_ADDR14_BRTAKEN, R_PPC64_ADDR14_BRNTAKEN,

	R_PPC64_REL16 entries.  Use complain_overflow_dont for R_PPC64_TOC.

	fields in instructions to signed/unsigned according to whether
	the field takes a signed or unsigned value.

	for a number of relocations.  Modify overflow test for 16-bit
	fields in instructions to signed/unsigned according to whether
	the field takes a signed or unsigned value.

8b974ba3e8 Simplify ppc64 code setting toc_off.
Every function has a nominal toc pointer value, even if it isn't used,
so set toc_off for every code section to the value used in that object
file.  The thinking here was that if a code section didn't use the toc
it could use the previous object file's toc pointer value.  It can,
but doing so is only a gain if functions in that section are called
mostly from previous objects sharing the same toc.  We lose if the
functions in question are called mostly from the current object or
following objects, and it's a good bet they will probably mostly be
called from the current object.

	* elf64-ppc.c (ppc64_elf_next_input_section): Always set toc_off

f9c6b9078c Report overflow on PowerPC64 @h and @ha relocations.
This changes the behaviour of @h and @ha on PowerPC64 to report errors
on 32-bit overflow.  The motivation for this change is that on
PowerPC64, most uses of @h and @ha modifiers and their corresponding
relocations are to build up 32-bit offsets.  We'd like to know when
such offsets overflow.  Only rarely do people use @h or @ha with the
high 32-bit modifiers to build a 64-bit constant.  Those uses will now
need to use two new modifiers, @high and @higha, if the constant isn't
known at assembly time.  For now, we won't report overflow at assembly
time..

This also fixes an error when applying some of the HIGHER and HIGHEST
relocations.
