        PR middle-end/44102
        * cfgcleanup.c (try_optimize_cfg): When removing trivially empty
        bb with no successors, move footer whenever in IR_RTL_CFGLAYOUT
        mode, not just when CLEANUP_CFGLAYOUT, and when in IR_RTL_CFGRTL
        add BARRIER after previous bb if needed.

        * g++.dg/ext/asmgoto1.C: New test.

Added:
    trunk/gcc/testsuite/g++.dg/ext/asmgoto1.C
