bffebb6ba5 Copy st_other for linker script symbol assignments
This fixes a problem seen on powerpc64le ELFv2 when creating a
function symbol alias with ld --defsym.  st_other needs to be copied
from the source symbol to the alias in order to set up the local entry
offset for the alias.  I decided to make this change in the generic
ELF code rather than in elf64-ppc.c since it looks like other targets
that use st_other bits might benefit too.

caa4096e84 Don't call bfd_link_hash_table_free
Freeing the linker hash table is a royal pain.  It can't be freed
before the _bfd_write_contents call in bfd_close, because some target
bfd_write_contents functions access the hash table.  It can't be freed
after bfd_close either, since bfd_alloc memory holding side data
structures disappears (PR17047).  Clearly the only place it can be freed
is actually in bfd_close.  This patch doesn't do that, but kills off
the existing means of freeing the hash table via a bfd target xvec call.

5979d6b69b Handle VDSO section headers past end of page
When a VDSO gets large enough that it doesn't entirely fit in one page,
but not so large that the part described by the program header exceeds
one page, then gdb/BFD doesn't read the section headers and symbol
table information.  This patch cures that by passing the size of the
vdso to BFD, and fixes a number of other issues in the BFD code.

	headers.  Handle zero p_align throughout.  Default loadbase to
	zero.  Add comments.  Rename contents_size to high_offset, and

5446cbdf82 ppc476 icache bug workaround
This implements a work-around for an icache bug on 476 that can cause
execution of stale instructions when control falls through from one
page to the next.  The idea is to prevent such fall-through by
replacing the last instruction on a page with a branch to a patch
area containing the instruction, then branch to the next page.

The patch also fixes a number of bugs in the existing support for long
branch trampolines.

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.

dc294be54c fix PR symtab/15597
This patch fixes gdb PR symtab/15597.

The bug is that the .gnu_debugaltlink section includes the build-id of
the alt file, but gdb does not use it.

This patch fixes the problem by changing gdb to do what it ought to
always have done: verify the build id of the file found using the
filename in .gnu_debugaltlink; and if that does not match, try to find
the correct debug file using the build-id and debug-file-directory.

This patch touches BFD.  Previously, gdb had its own code for parsing
.gnu_debugaltlink; I changed it to use the BFD functions after those
were introduced.  However, the BFD functions are incorrect -- they
assume that .gnu_debugaltlink is formatted like .gnu_debuglink.
However, it it is not.  Instead, it consists of a file name followed
by the build-id -- no alignment, and the build-id is not a CRC.

Fixing this properly is a bit of a pain.  But, because
separate_alt_debug_file_exists just has a FIXME for the build-id case,
I did not fix it properly.  Instead I introduced a hack.  This leaves
BFD working just as well as it did before my patch.

I'm willing to do something better here but I could use some guidance
as to what.  It seems that the build-id code in BFD is largely punted
on.

FWIW gdb is the only user of bfd_get_alt_debug_link_info outside of
BFD itself.

I moved the build-id logic out of elfread.c and into a new file.
This seemed cleanest to me.

Writing a test case was a bit of a pain.  I added a couple new
features to the DWARF assembler to handle this.

	* config/tc-mips.c: Add support for MIPS r5900
	Add M_LQ_AB and M_SQ_AB to support large values for instructions lq and sq.
	* config/tc-mips.c (can_swap_branch_p, get_append_method): Detect some conditional short loops to fix a bug on the r5900 by NOP in the branch delay slot.
	* config/tc-mips.c (M_MUL): Support 3 operands in multu on r5900.
	* config/tc-mips.c (M_TRUNCWS): Support trunc.w.s on r5900 in MIPS ISA I.
	* config/tc-mips.c (s_mipsset): Force 32 bit floating point on r5900.
	* configure.in: Detect CPU type when target string contains r5900 (e.g. mips64r5900el-linux-gnu).

	* config/tc-mips.c (mips_ip): Check parameter range of instructions mfps and mtps on r5900.

	* elf/mips.h: Add MIPS machine variant number for r5900 which is compatible with old Playstation 2 software.
	* opcode/mips.h: Add support for r5900 instructions including lq and sq.

	* configure.tgt: Support ELF files for Sony Playstation 2 (for ps2dev and ps2sdk).
	* emulparams/elf32lr5900n32.sh: Create linker script for Sony Playstation 2 ELF files using MIPS ABI n32.
	* emulparams/elf32lr5900.sh: Create linker script for Sony Playstation 2 ELF files using MIPS ABI o32.

	* opcodes/mips-opc.c: Add support for MIPS r5900 CPU.
	Add support for 128 bit MMI (Multimedia Instructions).
	Add support for EE instructions (Emotion Engine).
	Disable unsupported floating point instructions (64 bit and undefined compare operations).
	Enable instructions of MIPS ISA IV which are supported by r5900.
	Disable 64 bit co processor instructions.
	Disable 64 bit multiplication and division instructions.
	Disable instructions for co-processor 2 and 3, because these are not supported (preparation for later VU0 support (Vector Unit)).
	Disable cvt.w.s because this behaves like trunc.w.s and the correct execution can't be ensured on r5900.
	Add trunc.w.s using the opcode encoding of cvt.w.s on r5900. This will confuse less developers and compilers.
