H.J. Lu 5d69120bff i386: Set CHECK_RELOCS_AFTER_OPEN_INPUT to yes
All linker targets based on elf32-i386 should check relocations after
opening all inputs since this is how elf32-i386 works.

	* emulparams/i386lynx.sh (CHECK_RELOCS_AFTER_OPEN_INPUT): Set
	to yes.
	* emulparams/i386moss.sh (CHECK_RELOCS_AFTER_OPEN_INPUT):

Alan Modra 954b63d4c8 Implement -z dynamic-undefined-weak
-z nodynamic-undefined-weak is only implemented for x86.  (The sparc
backend has some support code but doesn't enable the option by
including ld/emulparams/dynamic_undefined_weak.sh, and since the
support looks like it may be broken I haven't enabled it.)  This patch
adds the complementary -z dynamic-undefined-weak, extends both options
to affect building of shared libraries as well as executables, and
adds support for the option on powerpc.

Alexey Neyman 4b5900d8b8 PowerPC: incorrect library search order
First, need to match against just the CPU name, not the whole triplet.
Otherwise, the test picks up "*le-*" pattern from x86_64-apple-darwin
triplet.

Second, it should be testing for $target, not $host. Host may be
little endian by default, and the sysroot directory layout shouldn't
depend on whether it is built on LE or BE machine.

	cpu, not host.

Palmer Dabbelt 10ddfe62f8 Don't use "_gp" on RISC-V, use "_global_pointer$" instead
"_gp" could conflict with ABI-complient code.  While it's probably OK
because MIPS uses this name, we figured it'd be good to clean this up
before a release with RISC-V in it.

Graham Markall 07ccf83cf5 [ARC] Add new linker emulation for nps
The arc700 nps variant uses some specific named sections to
facilitate its CMEM based instructions, which operate on memory
regions fixed at specific addresses.

This commit adds the arclinux_nps emulation, which is based on the
arclinux emulation. The new emulation uses the OTHER_SECTIONS
variable in the emulation parameters script to provide symbols
mapping to various locations in the CMEM space on nps.

The accompanying test ensures that all symbols are provided at the
correct address in the linker script.

  * Makefile.am: Add earclinux_nps.c target and add to
  ALL_EMULATION_SOURCES.
  * Makefile.in: Likewise, regenerated.
  * configure.tgt: Add arclinux_nps as an extra emulation for

Palmer Dabbelt 6ec11ab97a Remove some custom sections from RISC-V's default linker scripts
This was added so compressed loads could have smaller offsets for
accessing the data section, but the result was that writable sections
ended up in INITIAL_READONLY_SECTIONS.  This is a bad idea.  The fix is
to just remove this micro-optimization.

Thanks to Alan Morda for finding the problem!

Andrew Burgess 1a295c62e0 ld/arc: Make little endian default choice for linker scripts
When building with --enable-targets=all the target string is not set to
something that matches the pattern arc*-*, and so the script used to
decide if we should build big or little endian linker script currently
exits with an error.

This commit makes little endian linker script be the default, which will
be used when building for all targets, this matches the behaviour from
before I made the endianness switchable, when we only ever built little
endian linker scripts anyway.

ld/ChangeLog:

	* emulparams/arc-endianness.sh: Make little endian default choice.

Andrew Burgess 9a5f28ae28 ld/arc: Fix linker for big-endian arc targets
This aims to bring the linker for big-endian arc targets into line with
the linker for (the default) little endian arc targets.

The bulk of the changes are to extend the target pattern in the test
files from 'arc-*...' to 'arc*-*...' and so match both big and little
endian arc targets.

In the ld/emulparams/ directory the existing scripts checked for a
variable ARC_ENDIAN to switch between big and little endian targets,
however, this variable is never set up.

So, a new script snippet is introduced which sets up ARC_ENDIAN based on
the value of target, this snippet is then included from all of the
existing arc scripts.

The existing big-endian variants of all the scripts, which existed, but
were never used, are deleted in this commit.

H.J. Lu aec6b87e0b [x86] Resolve non-PIC undefweak symbols in executable
For i386 and x86-64, non-PIC references to undefined weak symbols are
resolved without dynamic relocation when creating executable.  Resolved
undefined weak symbols are removed from the dynamic symbol table in
executable.  One exception is on i386, we need resolved undefined weak
symbols in the dynamic symbol table in PIE if input relocatable files
contain branchs without PLT so that we can branch to 0 with dynamic
relocation in text section.

This makes behaviors of dynamic executable and position independent
executable predictable with mixed PIC and non-PIC references to undefined
weak symbols.  If all references to undefined weak symbols are PIC,
dynamic relocations against undefined weak symbols will be generated
in executable unless -z nodynamic-undefined-weak is passed to linker.

H.J. Lu 889c2a6796 Add -z noextern-protected-data to ld for ELF/x86
Address of protected data defined in the shared library may be external,
i.e., due to copy relocation.  By default, linker backend checks if
relocations against protected data symbols are valid for building shared
library and issues an error if relocation isn't allowed.  The new option
override linker backend default.  When -z noextern-protected-data is used,
updates on protected data symbols by another module won't be visibile
to the resulting shared library.  This option is specific to ELF/i386
and ELF/x86-64.

The changes to reorder sections for better relro protection on powerpc64,

Alan Modra 5ad18f16ab Reorder more powerpc64 sections again for -z relro
.toc1 is the second level TOC section used by gcc's -mminimal-toc.  It
too should be read-only after relocation.  Also, the last patch
description mentioned .sbss moving but didn't actually do that, so fix
that problem.  .tocbss (whatever that is) was before .sbss previously,
so move that one too.

Alan Modra 23283c1be0 Reorder more powerpc64 sections for -z relro
This moves .got too, which requires .sdata and .sbss to move with it,
because these sections share addressing via the toc pointer and with
small-model code must be within a 16-bit signed offset.  .plt, .iplt
and .branch_lt must also be moved since they are addressed via a
32-bit offset from the toc pointer, and we might have a very large
.data section.

This change means we may have some bss style sections before the data
segment, necessitating another PT_LOAD header.  Also, since _edata is
defined at the end of the data segment it's possible with an empty
.data to have _edata at the end of .plt which looks a little unusual
since .plt is a bss style section.  That should only happen rarely in
real world binaries, but does occur in the ld testsuite.

H.J. Lu dd7e64d45b Optimize out i386/x86-64 JUMP_SLOT relocation
When there are both PLT and GOT references to the same function symbol,
linker will create a GOTPLT slot for PLT entry and a GOT slot for GOT
reference.  A run-time JUMP_SLOT relocation is created to update the
GOTPLT slot and a run-time GLOB_DAT relocation is created to update the
GOT slot.  Both JUMP_SLOT and GLOB_DAT relocations will apply the same
symbol value to GOTPLT and GOT slots, respectively, at run-time.

This optimization combines GOTPLT and GOT slots into a single GOT slot
and removes the run-time JUMP_SLOT relocation.  It replaces the regular
PLT entry:

	indirect jump	[GOTPLT slot]
	push		relocation index
	jump		PLT0

with an GOT PLT entry with an indirect jump via the GOT slot:

	indirect jump	[GOT slot]
	nop

and resolves PLT reference to the GOT PLT entry.

We must avoid this optimization if pointer equality is needed since
we don't clear symbol value in this case and the dynamic linker won't
update the GOT slot.  Otherwise, the resulting binary will get into an
infinite loop at run-time.

Alan Modra 93d1b056cb Rewrite ppc32 backend .sdata and .sdata2 handling
1) _SDA_BASE_ and _SDA2_BASE_ and defined automatically, in a similar
   manner to the way _GLOBAL_OFFSET_TABLE_ is handled.  It's a little
   more complicated to remove the symbols because _SDA_BASE_ needs to
   be there if either .sdata or .sbss is present, and similarly for
   _SDA2_BASE.
2) The linker created .sdata and .sdata2 sections used for
   R_PPC_EMB_SDAI16 and R_PPC_EMB_SDA2I16 pointers are created early.
   Nowadays we strip unneeded sections from the output, so it isn't
   necessary to delay creating the sections.
3) The output section for targets of various SDA relocs is now checked
   as per the ABI(s).  We previously allowed .sdata.foo and similar,
   most likely because at some stage we were checking input sections.

Also, the patch fixes a long-standing bug in size_input_sections
that affects the values of symbols defined in stripped input
sections.

Nick Clifton 5063daf735 This patch adds a default manifest in to the final links performed by the Cygwin and MinGW targets.
The manifest is necessary in order for the linked binaries to be executed in a Windows 8 environment.

The manifest is added using a linker script so that this feature will be compiler-neutral.  The resource
merging code in the linker means that if an application provides its own manifest then the default
manifest will be ignored.

H.J. Lu 0ff2b86e7c Create the second PLT for BND relocations
Intel MPX introduces 4 bound registers, which will be used for parameter
passing in x86-64.  Bound registers are cleared by branch instructions.
Branch instructions with BND prefix will keep bound register contents.
This leads to 2 requirements to 64-bit MPX run-time:

1. Dynamic linker (ld.so) should save and restore bound registers during
symbol lookup.
2. Change the current 16-byte PLT0:

  ff 35 08 00 00 00	pushq  GOT+8(%rip)
  ff 25 00 10 00	jmpq  *GOT+16(%rip)
  0f 1f 40 00		nopl   0x0(%rax)

and 16-byte PLT1:

  ff 25 00 00 00 00    	jmpq   *name@GOTPCREL(%rip)
  68 00 00 00 00       	pushq  $index
  e9 00 00 00 00       	jmpq   PLT0

which clear bound registers, to preserve bound registers.

We use 2 new relocations:

to mark branch instructions with BND prefix.

When linker sees any R_X86_64_PC32_BND or R_X86_64_PLT32_BND relocations,
it switches to a different PLT0:

  ff 35 08 00 00 00	pushq  GOT+8(%rip)
  f2 ff 25 00 10 00	bnd jmpq *GOT+16(%rip)
  0f 1f 00		nopl   (%rax)

to preserve bound registers for symbol lookup and it also creates an
external PLT section, .pl.bnd.  Linker will create a BND PLT1 entry
in .plt:

  68 00 00 00 00       	pushq  $index
  f2 e9 00 00 00 00     bnd jmpq PLT0
  0f 1f 44 00 00        nopl 0(%rax,%rax,1)

and a 8-byte BND PLT entry in .plt.bnd:

  f2 ff 25 00 00 00 00  bnd jmpq *name@GOTPCREL(%rip)
  90			nop

Otherwise, linker will create a legacy PLT1 entry in .plt:

  68 00 00 00 00       	pushq  $index
  e9 00 00 00 00        jmpq PLT0
  66 0f 1f 44 00 00     nopw 0(%rax,%rax,1)

and a 8-byte legacy PLT in .plt.bnd:

  ff 25 00 00 00 00     jmpq  *name@GOTPCREL(%rip)
  66 90                 xchg  %ax,%ax

The initial value of the GOT entry for "name" will be set to the the
"pushq" instruction in the corresponding entry in .plt.  Linker will
resolve reference of symbol "name" to the entry in the second PLT,
.plt.bnd.

Prelink stores the offset of pushq of PLT1 (plt_base + 0x10) in GOT[1]
and GOT[1] is stored in GOT[3].  We can undo prelink in GOT by computing
the corresponding the pushq offset with

GOT[1] + (GOT offset - &GOT[3]) * 2

Since for each entry in .plt except for PLT0 we create a 8-byte entry in
.plt.bnd, there is extra 8-byte per PLT symbol.

We also investigated the 16-byte entry for .plt.bnd.  We compared the
8-byte entry vs the the 16-byte entry for .plt.bnd on Sandy Bridge.
There are no performance differences in SPEC CPU 2000/2006 as well as
micro benchmarks.

Pros:
	No change to undo prelink in dynamic linker.
	Only 8-byte memory overhead for each PLT symbol.
Cons:
	Extra .plt.bnd section is needed.
	Extra 8 byte for legacy branches to PLT.
	GDB is unware of the new layout of .plt and .plt.bnd.

H.J. Lu f6f6c6790a Skip directories with LIBPATH_SUFFIX_SKIP suffix
On Linux/x86-64, when binutils is configured with --libdir=/usr/lib64,
genscripts.sh treats /usr/lib64 as the default search directory.  It
puts /usr/lib64 in linker scripts for all emulations, like

---
/* Script for -z combreloc: combine and sort reloc sections */
OUTPUT_FORMAT("elf32-i386", "elf32-i386",
	      "elf32-i386")
OUTPUT_ARCH(i386)
ENTRY(_start)

Mike Frysinger 594d8fa8e9 strip off +x bits on non-executable/script files
These files are source files and have no business being +x.  We couldn't
easily fix it in CVS (you need login+write access to the raw rcs files),
but we can fix this w/git.
