Will Newton 7572ca8989 ld/ARM: Increase maximum page size to 64kB
Increase the maximum page size to 64kB and align the TEXT_START_ADDR
to a 64kB boundary. This brings AArch32 in line with AArch64 and
improves compatability under certain conditions.

2014-07-08  Will Newton  <will.newton@linaro.org>

	* elf32-arm.c (ELF_MAXPAGESIZE): Increase the default
	value to 64kB and remove custom setting for NaCl.

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)
SEARCH_DIR("/usr/x86_64-redhat-linux/lib32");
SEARCH_DIR("/usr/i386-redhat-linux/lib32"); SEARCH_DIR("/usr/lib6432");
SEARCH_DIR("/usr/local/lib32"); SEARCH_DIR("/lib32");
SEARCH_DIR("/usr/lib32"); SEARCH_DIR("/usr/i386-redhat-linux/lib");
SEARCH_DIR("/usr/lib64"); SEARCH_DIR("/usr/local/lib");
SEARCH_DIR("/lib"); SEARCH_DIR("/usr/lib");
---

/usr/lib6432 is odd and /usr/lib64 is wrong.  This patch changes
genscripts.sh to check LIBPATH_SUFFIX_SKIP if it is defined.  It
skips directories with LIBPATH_SUFFIX_SKIP suffix.

	PR ld/16456
	* genscripts.sh: Don't search directory with LIBPATH_SUFFIX_SKIP
	suffix.
	* emulparams/elf32_x86_64.sh (LIBPATH_SUFFIX_SKIP): Set to 64

	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.
