X-Git-Tag: releases/gcc-4.4.0~2117
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=9d92695c19c6d3082e6cc91db95e7263b06fd83c;p=thirdparty%2Fgcc.git

octeon-exts-2.c: Compile it with -meb.

	* gcc.target/mips/octeon-exts-2.c: Compile it with -meb.
	* gcc.target/mips/octeon-exts-5.c: New test.
	* gcc.target/mips/octeon-bbit-3.c: Compile with -meb.  Add
