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

This is an optimized memset for AArch64.  Memset is split into 4 main

destination and use an unrolled loop processing 64 bytes per
iteration.  Memsets of zero of more than 256 use the dc zva
instruction, and there are faster versions for the common ZVA sizes 64
or 128.  STP of Q registers is used to reduce codesize without loss of

Jon TURNEY 6c2b184277 Use makedoc generated texinfo documentation for reentrant syscalls
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

Marcus Shawcroft c7806ef76a [AArch64] Reverting recent optimized memset(). 2015-07-15 13:34:58 +01:00
Wilco Dijkstra 3263f90ef7 [AArch64] Optimized memset.
This is an optimized memset for AArch64.  Memset is split into 4 main
cases: small sets of up to 16 bytes, medium of 16..96 bytes which are
fully unrolled.  Large memsets of more than 96 bytes align the
destination and use an unrolled loop processing 64 bytes per
iteration.  Memsets of zero of more than 256 use the dc zva
instruction, and there are faster versions for the common ZVA sizes 64
or 128.  STP of Q registers is used to reduce codesize without loss of
performance.

Wilco Dijkstra b295f6ba44 [AArch64] Optimized memcpy.
This is an optimized memcpy for AArch64.  Copies are split into 3 main
cases: small copies of up to 16 bytes, medium copies of 17..96 bytes
which are fully unrolled.  Large copies of more than 96 bytes align
the destination and use an unrolled loop processing 64 bytes per
iteration.  In order to share code with memmove, small and medium
copies read all data before writing, allowing any kind of overlap.  On
a random copy test memcpy is 40.8% faster on A57 and 28.4% on A53.

Wilco Dijkstra 9503c7f275 [AArch64] Optimized memmove.
This is an optimized memmove for AArch64.  All copies of up to 96
bytes and all backward copies are done by the new memcpy.  The only
remaining case is large forward copies which are done in the same way
as the memcpy loop, but copying from the end rather than the start.

Yaakov Selkowitz 79e419de62 Rework handling of basename variants
As a commonly-included header, the #define basename in <string.h> can
affect code which uses "basename" for its own purposes (e.g. struct
members or C++ namespaced functions).  When such cases occur and some
code includes <string.h> and some not, then errors result.  OTOH,
<libgen.h> is rarely used, and that's where the renaming occurs in
glibc, so code using <libgen.h> should already be safe.

* libc/include/libgen.h (basename): Define as __xpg_basename
for source compatibility with glibc.
Declare with __ASMNAME("basename") for ABI compatibility.
* libc/include/string.h (basename): Define as basename for
source compatibility with glibc.
Declare with __ASMNAME("__gnu_basename") for ABI compatibility.

Jon TURNEY 44e5c14e08 Fix newlib texinfo source so 'info libc' and 'info libm' work
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'

newlib/ChangeLog:

2015-03-13  Jon TURNEY  <jon.turney@dronecode.org.uk>
