2017-07-31Compile pr79793-[12].c with -mtune=genericH.J. Lu3-2/+7
pr79793-1.c and pr79793-2.c are failed when GCC is configured with --with-cpu=slm since lea is used to adjust stack, instead of sub/add. This patch uses -mtune=generic to always generate sub and add. * gcc.target/i386/pr79793-1.c: Compile with -mtune=generic. * gcc.target/i386/pr79793-2.c: Likewise. From-SVN: r250745
