Anton Kolesov 668033eb9f arc: Fix strcmp for big endian without barrel shifter
strcmp.S contained invalid guard for code that used barrel-shifter optional
instruction - it was checking for !ARC601 instead of whether barrel shifter
is present. While it is true that ARC601 doesn't have barrel shifter, so
does some other ARC EM configurations.

Corinna Vinschen a68ca43b90 Redefine locale info in struct _reent for per-thread locales
The _reent members _current_category and _current_locale are not
used at all.  _current_locale is set to "C" in various points of
the code but its value is just as unused as _current_category.

This patch redefines these members without changing the size of the
structure to allow for an implementation of per-thread locales per
POSIX-1.2008 (i.e. uselocale and usage of the per-thread locale in
subsequent function calls).

Wilco Dijkstra e7b1ee2ea6 Add rawmemchr
Marcus Shawcroft wrote:

Sure, I've attached the patch.

Wilco

Add a simple rawmemchr implementation. Use strlen for rawmemchr(s, '\0') as it is the
fastest way to search for '\0', and use memchr with an infinite size for other cases.
This is 3x faster for large sizes.

ChangeLog:
2016-04-22  Wilco Dijkstra  <wdijkstr@arm.com>

        * newlib/libc/machine/aarch64/Makefile.in: Add rawmemchr.S and
        rawmemchr-stub.c.
        * newlib/libc/machine/aarch64/Makefile.am: Likewise.
        * newlib/libc/machine/aarch64/rawmemchr.S (rawmemchr): Add rawmemchr.
        * newlib/libc/machine/aarch64/rawmemchr-stub.c (rawmemchr): Likewise.

Corinna Vinschen 72ded59447 Make sure to have full configuration info in sys/_types.h.
The following testcase:

  $ cat > test.c <<EOF
  #include <sys/select.h>
  #include <sys/time.h>
  EOF
  $ gcc -c test.c

emits the following error:

  /usr/include/sys/reent.h:276:3: error: expected specifier-qualifier-list befor
e ‘_fpos64_t’
     _fpos64_t _EXFNPTR(_seek64, (struct _reent *, _PTR, _fpos64_t, int));
     ^

The reason is that the load order from sys/select.h includes sys/_types.h
before sys/config.h has been included from anywhere else.  sys/_types.h
defines _fpos64_t only if __LARGE64_FILES is defined, but it never is in
this scenario.  So sys/_types.h has to make sure to get the configuration
info by itself.

Sebastian Huber 3ad9b2fcba Provide __size_t via <sys/_types.h>
Various FreeBSD source and header files need a typedef __size_t via
<sys/_types.h>.  Unfortunately the GCC provided <stddef.h> uses

	#if (defined (__FreeBSD__) && (__FreeBSD__ >= 5)) \
	  || defined(__DragonFly__) \
	  || defined(__FreeBSD_kernel__)
	/* __size_t is a typedef on FreeBSD 5, must not trash it. */
	#elif defined (__VMS__)
	/* __size_t is also a typedef on VMS.  */
	#else
	#define __size_t
	#endif

and therefore defines __size_t on Newlib targets which would trash a
__size_t typedef.  Include <stddef.h> before <sys/_types.h> in
<sys/types.h> and undefine __size_t in <sys/_types.h> as a workaround.

Sebastian Huber 8a5af1a184 Use __machine_*_t_defined for internal types
Newlib defines defaults for internal types via <sys/_types.h> and uses
<machine/_types.h> to let targets define their own type if necessary.

Previously for example

	#ifndef __dev_t_defined
	typedef short __dev_t;
	#endif

However, the __*_t_defined pattern conflicts with the glibc type guard
pattern for user types, e.g. dev_t in this example.  Introduce a
__machine_*_t_defined pattern for internal types (defined by
<machine/_types.h>, used by <sys/_types.h>).  For example

	#ifndef __machine_dev_t_defined
	typedef short __dev_t;
	#endif

Sebastian Huber 477463a201 Eliminate use of Newlib-specific <machine/types.h>
This change solves a glibc/BSD compatibility problem.

glibc and BSD use double underscore types for internal types.  The Linux
port of Newlib uses some glibc provided internal type definitions which
are not protected by guard defines, e.g. __off_t.  To avoid a conflict
Newlib uses single underscore types for some internal types, e.g.
_off_t.  However, for BSD compatibility we have to define the internal
types with double underscore names in <sys/_types.h>.

The header file <machine/types.h> is Newlib-specific.  It was used
instead of <sys/_types.h> to provide the internal type definitions
_CLOCK_T, _TIME_T_, _CLOCKID_T_, _TIMER_T_, and __suseconds_t.  Move
these definitions to <sys/_types.h> (there exist two instances of this
file, one for Linux and one for all other targets).  This makes the
_HAVE_SYSTYPES configuration define obsolete (could possibly break the
__RDOS__ target).  Use the standard <sys/_types.h> include throughout.

Move __loff_t defintion to default (non-Linux) <sys/_types.h>.  Define
it via _off64_t to avoid a dependency on the compiler.

Provide the __off_t definition via default (non-Linux) <sys/_types.h>
based on _off_t for all systems except Cygwin.  For Cygwin use _off64_t.
Define off_t via __off_t.

Provide the __pid_t definition via default (non-Linux) <sys/_types.h>.
This prevents a potential __pid_t and pid_t incompatibility.  Add BSD
guard defines for pid_t.

Yaakov Selkowitz 722e363c4d math: guard BSD finite/isinf/isnan functions properly in math.h
Now that we have properly functioning feature test macros, the BSD
floating-point classification functions can go into math.h instead of
the non-standard ieeefp.h, and not under the C99 guard:

http://man7.org/linux/man-pages/man3/finite.3.html

The isnan function was in earlier versions of SUS but removed starting with
POSIX.1-2001, compare:

http://pubs.opengroup.org/onlinepubs/007908799/xsh/math.h.html
http://pubs.opengroup.org/onlinepubs/009695399/basedefs/math.h.html

Note that the isinf and isnan functions (but not the variants) conflict
with functions by the same name in C++11, hence they (and only they)
need to be hidden:

Apart from some self-written additions (exp10l, finite{f,l}, isinf{f,l},
isnan{f,l}, pow10l) the files are taken from the Mingw-w64 math lib.
Minor changes were required, e.g. substitue _WIN64 with __x86_64__ and
fixing __FLT_RPT_DOMAIN/__FLT_RPT_ERANGE for Cygwin.

Cygwin:
	* math: New subdir with math functions.
	* Makefile.in (VPATH): Add math subdir.
	(MATH_OFILES): List of object files collected from building files in
	math subdir.
	(DLL_OFILES): Add $(MATH_OFILES).

	* common.din: Add new functions from math subdir.
	* i686.din: Align to new math subdir.  Remove functions now commonly
	available.
	* x86_64.din: Ditto.
	* math.h: math.h wrapper to define mingw structs used in some files in
	math subdir.
	* include/cygwin/version.h: Bump API minor version.

newlib:
	* libc/include/complex.h: Add prototypes for complex long double
	functions.  Only define for Cygwin.
	* libc/include/math.h: Additionally enable prototypes of long double
	functions for Cygwin.  Add Cygwin-only prototypes for dreml, sincosl,
	exp10l and pow10l.  Explain why we don't add them to newlib.

While C++11 was the first version of the standard to use C99 functionality,
TR1 (for C++03) also does, and G++ does not distinguish between C++98 and
C++03, or when TR1 is in use.  Therefore, while not strictly correct for
"pure" C++98, enabling C99 for all C++ usage is the simplest solution (and

Cygwin provides currently its own implementation of the arc4random

Yaakov Selkowitz 6ba26630e0 Feature test macros overhaul: sys/features.h
This is the complete rework of the feature tests macros for better
compatibility with GNU libc, primarily based on the Linux man pages
documentation:

http://man7.org/linux/man-pages/man7/feature_test_macros.7.html

The previous implementation was flawed in its approach that macros were
often used to hide symbols if defined (e.g. !defined __STRICT_ANSI__ or
!defined _POSIX_SOURCE), whereas the approach of glibc is that these macros
make symbols available when defined (e.g. defined _BSD_SOURCE, or as used
internally, #if __BSD_VISIBLE).  As much open-source software is written
with glibc in mind, this necessitated patching numerous packages just to
compile.

In particular, __STRICT_ANSI__ (which is defined by gcc -ansi or -std=c*)
was given too much importance.  This implementation limits the influence
of __STRICT_ANSI__ to controlling the default when no other feature test
macros are defined, and to the inclusion of <alloca.h> in <stdlib.h> as
documented.  These are the only places where __STRICT_ANSI__ should be
tested.

The following macros are now accepted: _ATFILE_SOURCE, _BSD_SOURCE,
_DEFAULT_SOURCE, _ISOC99_SOURCE, _ISOC11_SOURCE, _LARGEFILE_SOURCE,
_SVID_SOURCE, _XOPEN_SOURCE_EXTENDED.

The existing __*_VISIBLE internal macros have been kept mostly
compatible with the original BSD implementation, with some changes to
the criteria which controls them.  Several more macros in this style
have been added where needed for concision or accuracy.

Enabling C++11 or newer in the compiler also enables C99 and C11
functions.  Doing so should help move away from the need to define
_GNU_SOURCE in g++ for _GLIBCXX_USE_C99 support as on Linux:

Pieter du Preez 264b817b8e Define the newlib version macros in one place: _newlib_version.h.
Currently, the newlib version information needs to be updated in two places:
 - newlib/acinclude.m4
 - newlib/libc/include/sys/features.h

The goal of this patch is to:
 - supply a single location for defining the newlib version
   information: newlib/acinclude.m4
 - define __NEWLIB__, __NEWLIB_MINOR__ and __NEWLIB_PATCHLEVEL__
   This is in line with what gcc does for its version macros. See:
   https://gcc.gnu.org/onlinedocs/cpp/Common-Predefined-Macros.html

This patch moves the definition of the _NEWLIB_VERSION, __NEWLIB__
and __NEWLIB_MINOR__ macros from newlib/libc/include/sys/features.h,
to the newly generated newlib/_newlib_version.h file. Additionally,
the __NEWLIB_PATCHLEVEL__ macro was created, for completeness.

In order to stay backwards compatible, newlib/_newlib_version.h gets
included by newlib/newlib.h and newlib/libc/include/sys/features.h.

Note: This patch does _not_ include the modifications to the following
files, as these should all be generated any way.
      *Makefile.in,
      *aclocal.m4,
      *configure

So intermediate one-arg macro will be enough to expand args before
final _sbrk_r expansion:

#define _SBRK_R(X) _sbrk_r(X)

Anton Kolesov 06537f05d4 ARC: Use new definitions for optional ARC CPU features
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.

Thomas Preud'homme 5b9873fa72 Check for 64 FP instructions availability in libm before using them
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.

        * libm/machine/arm/s_ceil.c: Also check that 64bit FP instructions are
        available in the guard.

Marcus Shawcroft bcd5e8e3f9 [ARM] Adding strlen.S
The patch adds strlen.S to contain the complementary preprocessor

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

Marcus Shawcroft 52f5864096 [ARM] Refactor strlen.c #if nesting.
This patch flattens the condition code selection used in strlen in an
attempt to make the guarding condition for each alternative

makes it easier to maintain complementary logic between the
alternative 'C' and assembler implementations.

Marcus Shawcroft 332a6236a2 Fix multilib libgloss selection.
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 00a4b31ad0
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.

Jon Turney 1129ef019f makedoc: Don't interpret license text as a command
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)

Jon Turney 81a7c8c37f doc: Fix some inconsistent QUICKREF lines
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.

Jon Turney 0c02db4d28 makedoc: Fix INTERNAL(|DEFINITION|FUNCTION) command definitions
The unused INTERNAL_DEFINITION, INTERNAL_FUNCTION and INTERNAL commands are
defined in terms of the non-existent built-in 'func'

This causes every single invocation of makedoc to output "Can't find func" three

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.

Joseph Myers e6459123e4 Avoid .eh_frame in ARM newlib.
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.

Marcus Shawcroft d18f1fc8a3 Reorganize memchr selection.
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

Corinna Vinschen e6d9af11f1 strlen-armv7.S: Fix preprocessor check
Hi!

I've got the situation, that the function strlen() occurs twice in libc.a
(building newlib for ARM-V7a and Size-Optimized).

In newlib/libc/machine/arm/strlen.c there are the pre-processor stetements ...
#if defined (__OPTIMIZE_SIZE__) || defined (PREFER_SIZE_OVER_SPEED) || \
  (defined (__thumb__) && !defined (__thumb2__))
/*...*/
#else

#if !(defined(_ISA_ARM_7) || defined(__ARM_ARCH_6T2__))
/*...*/
#endif

and in newlib/libc/machine/arm/strlen-armv7.S the "exclude" begins with

/* NOTE: This ifdef MUST match the ones in arm/strlen.c
   We fallback to the one in arm/strlen.c for size optimised or
   for older architectures. */
#if defined(_ISA_ARM_7) || defined(__ARM_ARCH_6T2__) && \
    !(defined (__OPTIMIZE_SIZE__) || defined (PREFER_SIZE_OVER_SPEED) || \
      (defined (__thumb__) && !defined (__thumb2__)))

But this is not completely contrary to arm/strlen.c (see above)!

To fix the logical statement in arm/strlen-armv7.S there are parentheses needed

James Greenhalgh 4eca8ea0cf Always declare "kill" in include/sys/signal.h
Hi,

As I mentioned recently [1], newlib is providing a "kill" symbol to link
against, without declaring "kill" in signal.h. This is confusing for the
libgfortran build, which tries to link against kill (which succeeds), then
tries to use it (which triggers -Werror=implicit-function-declaration).

This patch implements my suggestion in that thread - making the declaration
of 'kill' in libc/include/sys/signal.h unconditional.

I've tested this by building a modified libgfortran on AArch64/ARM to see
that the Werror goes away, and the libgfortran build succeeds.

Is something like this OK for newlib? If so, can someone please commit
it on my behalf, as I have no commit access here.

Otherwise, what is your preferred direction for me to take this patch?

Thanks,
James

So it seems this problem has been around for a while, and looks like it
is due to a change in texi2dvi in texinfo 5.0 or late 4.x, see [1].

I guess it's not very noticeable since it only occurs when doing 'make
dvi', which doesn't happen by default.

Attached is a different and perhaps cleaner workaround to the one in
that thread.

Hi Richard,

ARM's machine/param.h that is included in "#include <machine/param.h>",
before the 'ifndef' already defines HZ to be 100. This file was already
there, it was just not being used. I understand that this 'ifndef' might
be confusing, though I decided to add it to mimic the behavior of the
default sys/param.h.

There is however an unrelated issue with this patch, a typo in the
"#define NOFILE" that crept in there due to some copy pasting when
splitting the patch.

Here is a fixed version.

BR,
Andre

We use texinfo nodes beginning with an underscore in several other places, so
revert this ancient workaround for a no longer existing bug, and use the makedoc
generated texinfo for reentrant versions of syscalls, rather than handwritten
documentation.

Also alphabetically sort these functions.

Also add documentation for _execve_r, _getpid_r, _kill_r and _times_r functions,
whose non-reentrant versions are documented as stubs

v2:
Keep _open64_r, _lseek64_r and _fstat64_r functions under texinfo conditional STDIO64
Add _stat64_r function likewise.

Notes:

1. The handwritten prototypes give the reentrancy structure pointer as of type
void *, rather than the presumably more correct struct __reent *

2. The fcntl, gettimeofday, mkdir and rename functions are not documented as
stubs, so I haven't added the reentrant versions either

If the newlib .info files are installed using install-info, 'info libc' and
'info libm' don't work.

This seems to be due to the formatting of the directory entry line not being
quite right, so fix that.

Also use @direntry texinfo command, rather than writing .info directory entry
literally.

Also use @dircategory texinfo command to place into 'Newlib' category, rather
than ending up in 'Miscellaneous'
