If small reent is enabled (_REENT_SMALL is defined) then malloc() was
used in __register_exitproc() even if user requested it to be disabled
(_ATEXIT_DYNAMIC_ALLOC is defined). With this fix, function fails when
_ATEXIT_DYNAMIC_ALLOC is defined and whole static storage is already
used.

GCC for ARC has been updated to provide consistent naming of preprocessor
definitions for different optional architecture features:
* __ARC_BARREL_SHIFTER__ instead of __Xbarrel_shifter for
-mbarrel-shifter
* __ARC_LL64__ instead of __LL64__ for -mll64
* __ARCEM__ instead of __EM__ for -mcpu=arcem
* __ARCHS__ instead of __HS__ for -mcpu=archs
* etc (not used in newlib)
This patch updates assembly routines for ARC to use new definitions instead
of a deprecated ones. To ensure compatibility with older compiler new
definitions are also defined in asm.h if needed, based on deprecated
preprocessor definitions.

Currently, double precision math functions in newlib/libm/machine/arm detect whether neon instructions can be used for double precision computation by checking the architecture version (>= 8) and the availability of floating-point instructions. However, these instructions would not be available if targeting fpv5-sp-d16 as the FPU, which by definition does not have 64bit float instructions. This patch adds a check that __ARM_FP advertises 64bit float instructions.

The patch adds strlen.S to contain the complementary preprocessor
logic to strlen-stub.c intended to provide #inclusion of alternative
.S implementations.
Initially we just include the existing strlen-armv7.S implementation.
We rewrite _ISA_ARMV7 in both strlen.S and strlen-stub.c to use the
underlying existing underlying defintion from arm_asm.h in order to
avoide including that file, this is in effect the first step towards a
move to ACLE predefines only.

Regression testing newlib in conjunction with libgloss and
--enable-multilib can result in incompatible multilib versions of
newlib and libgloss being used during link.
This manifests on ARM target when newlib regression is run using a
GCC configured using --with-multilib-list=aprofile
With this configuration many of the multilib variants built are
mutually incompatible.
The issue is that the newlib dejagnu foo iterates each multilib
variant and correctly chooses the appropriate newlib variant but
always chooses the root/base libgloss variant.
The implementation of newlib/testsuite/lib/flags.exp contains the
following fragment:
set target_build_path "$objdir/$multibuildtop.."
The effect of this fragment is to explicitly select the root version
of libgloss, irrespective of the current multilib.
Digging around in VC it appears that the original implementation of
multlib magic came into the tree back in 2002 with:
6e9d950a (Thomas Fitzsimmons 2002-05-01 17:06:25 +0000 39)
In this initial version of multilib support, newlib was multilib
capable, but libgloss was not multilib capable, hence the necessity to
explicitly select the root libgloss version.
Subsequently flags.exp was modified to support out of tree testing:
cec1d3b4 (Jeff Johnston 2005-07-05 00:11:50 +0000 25)
This change is orthogonal to this issue, its effect is to exit early
in none multilib configurations.
Subsequently libgloss gained --enable-multilib support, the relevant
change is:
https://sourceware.org/ml/newlib/2006/msg00440.html
commit 00a4b31ad08aef361c5d74125ece410b4c285975
Author: Jeff Johnston <jjohnstn@redhat.com>
Date: Wed May 10 20:51:41 2006 +0000
This change enabled multilib support throughout libgloss, but ommitted
to adjust the flag.exp behaviour which anchors the libgloss multilib
selection to the base version.
The attached patch adjusts flags.exp to select the current multilib
variant of libgloss.
2015-11-06 Marcus Shawcroft <marcus.shawcroft@arm.com>
* testsuite/lib/flags.exp (libgloss_link_flags): Drop multilibtop
from target_build_path.

Align makedoc's iscommand() with it's documentation, and don't allow commands to
contain a space. A command is a line containing only a sequence of capital
letters or '_', followed by optional spaces.
This prevents "IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE" (the only line in the license text which consists of only
capitals and spaces, without any punctuation) from being interepreted as a
makedoc command, leading to:
"Can't find IMPLIED"
"warning, IMPLIED is not recognised"
being emitted by makedoc, (which is normally un-noticed because makedoc's stderr
is redirected to a .ref file)

makedoc defines a command as 'all upper case, and alone on a line'.
A few QUICKREF lines currently violate this by having some additional text after
the QUICKREF.
So, currently, these lines are treated as an unknown command.
This is benign as QUICKREF currently does nothing but produce some ignored
output on stderr. I'm not sure what the intent of QUICKREF is.

The unused INTERNAL_DEFINITION, INTERNAL_FUNCTION and INTERNAL commands are
defined in terms of the non-existent built-in 'func'

times, as it parses doc.str.
This is normally un-noticed because makedoc's stderr is redirected to a .ref
file.
Fix these unused command definitions to something with equivalent lack of
effect, but without generating an error.

* newlib/libc/machine/aarch64/memcpy.S (memcpy):
Further tuning for performance.
|
|
ARM newlib has various strcmp implementations that use .cfi_*
directives to generate unwind information.
The effect of this is that the generated objects contain .eh_frame
sections. However, ARM uses its own unwind info format, not
.eh_frame, which is generated by ARM-specific directives, not .cfi_*.
The .eh_frame sections are useless, but also not removed by strip and
may be loaded into memory at runtime.
This patch fixes this by using .cfi_sections .debug_frame (as in
glibc) so that the directives generate .debug_frame instead.
.debug_frame is useful for the debugger, can be removed by strip, and
is not loaded into memory at runtime.

The patch cleans up the auto configury mechanism used to select
different implementations of memchr for various architecture versions.
The approach here is to remove the selection of memchr within automake
and instead use complimentary logic in memchr-stub.c and memchr.S to
choose between the gerneric memchr.c implementation or one of the
architecture specific implementations.
This patch also changes the selection criteria inline with the
previous proposal here:
https://sourceware.org/ml/newlib/2015/msg00752.html
but using the ACLE predefines.
Regressed for armv7-a armv5 armv8-a, correct selection of memcpy
implementation by manual inspection of a test program built for these
three architectures.
