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

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.

The file libgloss/rl78/write.c currently contains code which outputs
\r when \n is seen. The code will then output the \n as well.
This patch removes the bit of code that tests for \n and then outputs
\r.
I made this change to fix some failures in gdb.base/call-ar-st.exp. In
that test, I see two carriage returns followed by a newline. One CR is
output by the libgloss code. The other is output by the terminal driver.
The total list of failures fixed (using the default rl78 multilib) are:
FAIL: gdb.base/call-ar-st.exp: print print_double_array(double_array) (timeout)
FAIL: gdb.base/call-ar-st.exp: print print_char_array(char_array) (timeout)

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.

available in the guard.

* mount.cc (mount_info::from_fstab_line): Support mounting the current
user's temp folder as /tmp/. This is particularly useful a feature
when Cygwin's own files are write-protected.
* pathnames.xml: document the new usertemp file system type
Detailed explanation:
In the context of Windows, there is a per-user directory for temporary
files, by default specified via the environment variable %TEMP%. Let's
allow to use that directory for our /tmp/ directory.
With this patch, we introduce the special filesystem type "usertemp":
By specifying
none /tmp usertemp binary,posix=0 0 0
in /etc/fstab, the /tmp/ directory gets auto-mounted to the directory
specified by the %TEMP% variable.
This feature comes handy in particularly in scenarios where the
administrator might want to write-protect the entire Cygwin directory
yet still needs to allow users to write into the /tmp/ directory.
This is the case in the context of Git for Windows, where the
Cygwin (MSys2) root directory lives inside C:\Program Files and hence
/tmp/ would not be writable otherwise.
