Subject: [ARM] Remove deprecated mwords-little-endian.
X-Git-Tag: releases/gcc-5.1.0~6476
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8adb5dc735298d2113de33ce442831f4dab9d215;p=thirdparty%2Fgcc.git

[ARM] Remove deprecated mwords-little-endian.

	* config/arm/arm.opt (mwords-little-endian): Delete.
	* config/arm/arm.h (TARGET_CPU_CPP_BUILTINS): Remove handling
	of TARGET_LITTLE_WORDS.
	(WORDS_BIG_ENDIAN): Define to BYTES_BIG_ENDIAN.
	* config/arm/arm.c (arm_option_override): Remove TARGET_LITTLE_WORDS
	warning.
	* doc/invoke.texi: Remove references to -mwords-little-endian.
