Subject: arm: remove error in CPP_SPEC when -mlittle-endian and -mbig-endian are used together
X-Git-Tag: upstream/12.2.0~7880
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4a322345cab10879162a2ddf659fb0f873ba0182;p=platform%2Fupstream%2Fgcc.git

arm: remove error in CPP_SPEC when -mlittle-endian and -mbig-endian are used together

arm.h has had this error message since 1997, but it is no longer
needed since option parsing has been improved: -mXXX-endian is handled
via arm.opt and updates the BIG_END mask. So, the last
instance of -mXXX-endian on the command line wins.

Tested on many arm* configurations, with no impact on the testsuite results.

	gcc/
	* config/arm/arm.h (CPP_SPEC): Remove error message about
	-mlittle-endian/-mbig-endian conflict.
