ef9faf1385 Fix libm feholdexcept namespace (bug 17748).
Continuing the fixes for C90 libm functions calling C99 fe* functions,
this patch fixes the case of feholdexcept by making it a weak alias of
__feholdexcept and making the affected code call __feholdexcept.

Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch).  Also tested for ARM
(soft-float) that feholdexcept failures disappear from the
linknamespace test failures (fesetenv, fsetround and feupdateenv
remain to be addressed to complete fixing bug 17748).

	[BZ #17748]
	* include/fenv.h (__feholdexcept): Declare.  Use
	libm_hidden_proto.
	* math/feholdexcpt.c (feholdexcept): Rename to __feholdexcept and
	define as weak alias of __feholdexcept.  Use libm_hidden_weak.

4841e6a6c2 Use libc calls defined by fenv_private.h to implement several fenv functions
rather than duplicating functionality. To make this work for softfp builds,
ensure functions in fenv_private are not conditionally compiled.

2014-06-24  Wilco  <wdijkstr@arm.com>

	* sysdeps/arm/fegetround.c (fegetround): Call get_rounding_mode.
	* sysdeps/arm/feholdexcpt.c (feholdexcept): Call libc_feholdexcept_vfp.
	* sysdeps/arm/fesetround.c (fesetround): Call libc_fesetround_vfp.
	* sysdeps/arm/fgetexcptflg.c (fegetexceptflag):
	Call libc_fetestexcept_vfp.
	* sysdeps/arm/ftestexcept.c (fetestexcept): Call libc_fetestexcept_vfp.
	* sysdeps/arm/fenv_private.h: Move libc_*_vfp functions outside of
	__SOFTFP__ ifdef so that they can be built for softfp.

c6bfe5c4d7 Move arm from ports to libc.
I've moved the ARM port from ports to the main sysdeps hierarchy.
Beyond the README update, the move of the files was simply

git mv ports/sysdeps/arm sysdeps/arm
git mv ports/sysdeps/unix/arm sysdeps/unix/arm
git mv ports/sysdeps/unix/sysv/linux/arm sysdeps/unix/sysv/linux/arm

and in addition to the ChangeLog entries here, I put a note at the top
of ports/ChangeLog.arm similar to that at the top of
ChangeLog.powerpc.  There is deliberately no NEWS change, as I think
it makes the most sense to put in a general note above all ports
having moved if we can achieve that for 2.20.

Tested that disassembly of installed shared libraries for arm is the
same before and after this patch, except for data (not instructions)
in ld.so (there are assertions in sysdeps/arm/dl-machine.h, and the
path by which that file is found, and so by which it appears in the
assertion message, changes as a result of the move).

	* sysdeps/arm: Move directory from ports/sysdeps/arm.
	* sysdeps/unix/arm: Move directory from ports/sysdeps/unix/arm.
	* sysdeps/unix/sysv/linux/arm: Move directory from
	ports/sysdeps/unix/sysv/linux/arm.
	* README: Update listing for arm-*-linux-gnueabi.

ports/ChangeLog.arm:
	* sysdeps/arm: Move directory to ../sysdeps/arm.
	* sysdeps/unix/arm: Move directory to ../sysdeps.arm.
	* sysdeps/unix/sysv/linux/arm: Move directory to
	../sysdeps/unix/sysv/linux/arm.
