            * config.gcc (amdgcn-*-*): Add gfx1030 and gfx1100 to
            TM_MULTILIB_CONFIG.
            * doc/install.texi (Configuration amdgcn-*-*): Mention gfx1030/gfx1100.
            * doc/invoke.texi (AMD GCN Options): Add gfx1030 and gfx1100 to

    libgomp/ChangeLog:
    
            * testsuite/libgomp.c/declare-variant-4.h: Add variant functions
            for gfx1030 and gfx1100.
            * testsuite/libgomp.c/declare-variant-4-gfx1030.c: New test.
            * testsuite/libgomp.c/declare-variant-4-gfx1100.c: New test.
