poky/meta/recipes-devtools/gcc/gcc-7.3/no-sse-fix-test-case-failures.patch
Mark Hatle 82f139e003 gcc: Fix test case issue when SSE is not enabled 
Whenever "-mno-sse" is used, "-mfpmath" should be set to 387.

The test case should be modified accordingly as below:

/* { dg-additional-options "-mno-sse -mfpmath=387 " { target { i?86-*-* x86_64-*-* } } } */

Subject: [PATCH] Fix for testsuite failure

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.
