Hi,

This patch (diff-mcall) fixes big-endian assumptions for -mcall-aixdesc
and various others.

Thanks,
Bill


2014-03-19  Bill Schmidt  <wschmidt@linux.vnet.ibm.com>

	Backport from mainline r207658
	2014-02-06  Ulrich Weigand  <Ulrich.Weigand@de.ibm.com>

	* config/rs6000/sysv4.h (ENDIAN_SELECT): Do not attempt to enforce
	big-endian mode for -mcall-aixdesc, -mcall-freebsd, -mcall-netbsd,
	-mcall-openbsd, or -mcall-linux.
	(CC1_ENDIAN_BIG_SPEC): Remove.
	(CC1_ENDIAN_LITTLE_SPEC): Remove.
	(CC1_ENDIAN_DEFAULT_SPEC): Remove.
	(CC1_SPEC): Remove (always empty) %cc1_endian_... spec.
	(SUBTARGET_EXTRA_SPECS): Remove %cc1_endian_big, %cc1_endian_little,
	and %cc1_endian_default.
	* config/rs6000/sysv4le.h (CC1_ENDIAN_DEFAULT_SPEC): Remove.
