The new macOS 10.12 way of loading dylib (placing them at the end of the currently
loaded segments) requires that Valgrind needs to know where the last segment was loaded.
A new structure (load_info_t) has been created to store all this information and easily
carry it around.
Changes:
- dyld text address is relative instead of absolute (macOS 10.12)
- Handle dylinker's offset (macOS 10.12)
- Handle the executable requesting a non-default stack address (macOS 10.12)
- Refactor to use load_info_t structure (all macOS)

Rerunning valgrind under valgrind shows that interp_name and interp_args
memory was freed twice.
=> reworked the way interp_name and interp_args are freed:
* free them in VG_(ii_create_image) (linux/darwin/solaris)
* everywhere else, when overriden, first free the current value
* everywhere where interp_name or interp_args are freed, set them to NULL
With this, re-selfhosting valgrind shows no leak and no corruption
for interp_name and interp_args.

SUNWDTRACE program header. Newer Solaris no longer utilizes
this program header as a scratchspace for DTrace fasttrap
provider, before libc is loaded.
For the time being, it serves as a space for initial thread
pointer.

With this patch, MIPS32 Valgrind compiled with -mfpxx can handle all types
(regarding FP_ABI flag) of MIPS32 ELFs.
- Functions arch_elf_pt_proc() and arch_check_elf() are added to elf reader
according to linux/fs/binfmt_elf.c from Linux 4.1;
- Processing .MIPS.abiflags section and initializing appropriate FPU mode
for MIPS32 are added;
- Emulation of prctl(GET/SET_FP_MODE) sys-calls are implemented for MIPS32.

Initial data segment is established (see initimg-solaris.c for rationale):
- directly during client program image initialization,
- or on demand when the executed program is the runtime linker itself,
after it has loaded its target dynamic executable (see PRE(sys_mmapobj)),
or when the first brk() syscall is made.
More preparatory work for ldsoexec support.

Not so; relative path works just fine.

POWER PC, add the functional Little Endian support, patch 2
The IBM POWER processor now supports both Big Endian and Little Endian.
The ABI for Little Endian also changes. Specifically, the function
descriptor is not used, the stack size changed, accessing the TOC
changed. Functions now have a local and a global entry point. Register
r2 contains the TOC for local calls and register r12 contains the TOC
for global calls. This patch makes the functional changes to the
Valgrind tool. The patch makes the changes needed for the
none/tests/ppc32 and none/tests/ppc64 Makefile.am. A number of the
ppc specific tests have Endian dependencies that are not fixed in
this patch. They are fixed in the next patch.
Per Julian's comments renamed coregrind/m_dispatch/dispatch-ppc64-linux.S
to coregrind/m_dispatch/dispatch-ppc64be-linux.S Created new file for LE
coregrind/m_dispatch/dispatch-ppc64le-linux.S. The same was done for
coregrind/m_syswrap/syscall-ppc-linux.S.

POWER PC, add initial Little Endian support
The IBM POWER processor now supports both Big Endian and Little Endian.
This patch renames the #defines with the name ppc64 to ppc64be for the BE
specific code. This patch adds the Little Endian #define ppc64le to the
Additionally, a few functions are renamed to remove BE from the name if the
function is used by BE and LE. Functions that are BE specific have BE put
in the name.
The goals of this patch is to make sure #defines, function names and
variables consistently use PPC64/ppc64 if it refers to BE and LE,
PPC64BE/ppc64be if it is specific to BE, PPC64LE/ppc64le if it is LE
specific. The patch does not break the code for PPC64 Big Endian.
The test files memcheck/tests/atomic_incs.c, tests/power_insn_available.c
and tests/power_insn_available.c are also updated to the new #define
definition for PPC64 BE.

expected to be loaded (as expressed in the ELF headers) and where it was
actually loaded, and not (as valgrind was doing) the absolute value of the
load address for the interpreter.
Note that when prelink is not in use the two are normally the same, as the
intpreter (like all shared libraries) is normally linked with a zero load
address. When prelinked that is no longer true.
With that fixed, the hack to patch out AT_BASE to avoid confusing gdb on
systems where prelink is in use is no longer needed.
