Subject: [PATCH] Fix for testsuite failure

2017-11-16  Raghunath Lolur  <raghunath.lolur@kpit.com>

	* gcc.dg/pr56275.c: If SSE is disabled, ensure that
	"-mfpmath" is not set to use SSE. Set "-mfpmath=387".
	* gcc.dg/pr68306.c: Likewise
	* gcc.dg/pr68306-2.c: Likewise
	* gcc.dg/pr68306-3.c: Likewise
	* gcc.dg/pr69634.c: Likewise
	* gcc.target/i386/amd64-abi-1.c: Likewise
	* gcc.target/i386/funcspec-6.c: Likewise
	* gcc.target/i386/interrupt-387-err-1.c: Likewise
	* gcc.target/i386/isa-14.c: Likewise
	* gcc.target/i386/pr44948-2b.c: Likewise
	* gcc.target/i386/pr53425-1.c: Likewise
	* gcc.target/i386/pr53425-2.c: Likewise
	* gcc.target/i386/pr55247.c: Likewise
	* gcc.target/i386/pr59644.c: Likewise
	* gcc.target/i386/pr62120.c: Likewise
	* gcc.target/i386/pr70467-1.c: Likewise
	* gcc.target/i386/warn-vect-op-1.c: Likewise

If -Wall, -Werror are used during compilation various test cases fail
to compile.

If SSE is disabled, be sure to -mfpmath=387 to resolve this.

This patch removes the changes to Changelog from the original patch.
This will help us avoid conflicts.
