Many POSIX systems have the bad habit of not restarting interrupted
syscalls. On these systems it's up to the user to check for an error
with errno == EINTR and restart manually. This patch does this for
libgfortran, so that GFortran users don't have to do it.

rs6000-c.c (rs6000_cpu_cpp_builtins): Split -mfloat128 into -mfloat128-type that enables the IEEE 128-bit floating...

[gcc]
2016-10-06  Michael Meissner  <meissner@linux.vnet.ibm.com>

	* config/rs6000/rs6000-c.c (rs6000_cpu_cpp_builtins): Split
	-mfloat128 into -mfloat128-type that enables the IEEE 128-bit
	floating point type infrastructre, and -mfloat128 that enables the
	keyword.  Define __FLOAT128__ if -mfloat128, and __FLOAT128_TYPE__
	if -mfloat128-type.  Define __ibm128 to be long double by default.
	* config/rs6000/rs6000.c (rs6000_debug_reg_global): Print whether
	the IEEE 128-bit floating point type infrastructure should
	automatically be enabled.
	(rs6000_init_hard_regno_mode_ok): Switch to use -mfloat128-type
	instead of -mfloat128 to enable KFmode.
	(rs6000_option_override_internal): Split the option -mfloat128
	into -mfloat128-type and -mfloat128.  On Linux PowerPC 64-bit
	systems, automatically set -mfloat128-type, but don't enable it on
	other operating systems.  Move setting the long double size and
	IEEE quad support before the IEEE 128-bit floating point changes.
	(rs6000_init_builtins): Do not create a unique type for __ibm128
	if long double is IBM extended double, instead rely on __ibm128
	being defined as 'long double'.  If -mfloat128-type and not
	-mfloat128, create the KFmode type with an undocumented __ieee128
	keyword.
	(rs6000_init_libfuncs): Use -mfloat128-type instead of
	-mfloat128 for tests about the types, but keep tests for
	-mfloat128 to enable the keyword support.

	-mfloat128-hardware, which was missing.
	* config/rs6000/rs6000.opt (-mfloat128): Split -mfloat128 into
	-mfloat128 and -mfloat128-type:
	(-mfloat128-type): Likewise.
