a8b5de7ff5 Don't display trailing '.' in _dcvt
In the two helper functions that _dcvt calls for 'f' and 'e' mode, if
there are no digits to display after the decimal point, don't add one.

towards the 'ndigits' limit.

256f1171ac newlib: Build internal strtold code only if HAVE_LONG_DOUBLE defined
Commit fbace81684f8cbb80a2048c01dc545af247f5cb7
("Import correctly working strtold from David M. Gay.")
introduced two new files, strtorx.c and strtodg.c.  The functions
are only called from strtold.c.  However, while strtold.c is only
built if HAVE_LONG_DOUBLE is defined, the patch erroneously added
the two new files to GENERAL_SOURCES unconditionally.

Fix this by building both files only if HAVE_LONG_DOUBLE has been
defined.

35555851d7 newlib: strtold: use __builtin_nanl to avoid libm dependency
Commit 6c212a8b7873703c4f98c6b68579b234918be83a
("Fix strtod ("nan") and strtold ("nan") returns wrong negative NaN")
introduced an unconditional dependency to nanl and, in turn, to libm.

Rather than including nanl in libc as well, just call __builtin_nanl
from here.  Requires GCC 3.3 or later.

3b6994ec5f stdlib: Use __get_numeric_locale instead of __localeconv_l for decimal_point
The string/float conversion functions need to get the locale decimal

into lconv form from __get_numeric_locale), use __get_numeric_locale

c8d4c99ecd Fix strtof ("-nan") returns positive NaN
strtof ("-nan") returned positive NaN instead of negative NaN.
strtod ("-nan") and strtold ("-nan") return negative NaN.

Linux glibc has been fixed
that strto{f|d|ld} ("-nan") returns negative NaN.
https://sourceware.org/bugzilla/show_bug.cgi?id=23007

This commit makes strtof preserves the negative sign bit
when parsing "-nan" like glibc.

6c212a8b78 Fix strtod ("nan") and strtold ("nan") returns wrong negative NaN
The definition of qNaN for x86_64 and i386 was wrong.
strto{d|ld} ("nan") returned wrong negative NaN
instead of correct positive NaN
since it used the wrong definition.

On the other hand, strtof ("nan") returns correct positive NaN
since it uses nanf ("") instead of the wrong definition.

This commit makes strto{d|ld} ("nan") uses {nan|nanl} ("")
like strtof ("nan") using.
So strto{d|ld} ("nan") returns positive NaN.

27652b608d strtod: Convert 64 bit double to 64 bit int during computation
The gdtoa implementation uses the type long, defined as Long, in lots
of code.  For historical reason newlib defines Long as int32_t instead.

This works fine, as long as floating point exceptions are not enabled.
The conversion to 32 bit int can lead to a FE_INVALID situation.

Example:

  const char *str = "121645100408832000.0";
  char *ptr;

  feenableexcept (FE_INVALID);
  strtod (str, &ptr);

This leads to the following situation in strtod

  double aadj;
  Long L;

  [...]
  L = (Long)aadj;

For instance, on x86_64 the code here is

  cvttsd2si %xmm0,%eax

At this point, aadj is 2529648000.0 in our example.  The conversion to
32 bit %eax results in a negative int value, thus the conversion is
invalid.  With feenableexcept (FE_INVALID), a SIGFPE is raised.

Fix this by always using 64 bit ints here if double is not a 32 bit type
to avoid this type of FP exceptions.

f70d9ae6ad Use enum __packed in favour of -fshort-enums
Some architectures like ARM encode the short enum option state in the
object file and the linker checks that this option is consistent for all
objects of an executable.  In case applications use -fno-short-enums,
then this leads to linker warnings.  Use the enum __packed attribute for
the relevent enums to avoid the -fshort-enums compiler option.  This
attribute is at least available on GCC, LLVM/clang and the Intel
compiler.

fa55c610fa Only define static locks in multithreaded mode
Newlib build system defines __SINGLE_THREAD__ to allow concurrency code
to be only compiled when newlib is configured for multithread. One such
example are locks which become useless in single thread mode. Although
most static locks are indeed guarded by !defined(__SINGLE_THREAD__),
some are not.

This commit adds these missing guards to __dd_hash_mutex,
__atexit_recursive_mutex, __at_quick_exit_mutex and __arc4random_mutex.
It also makes sure locking macros in lock.h are noop in single thread
mode.
