        Description

        The compiler directive BreakAtExecute now can only instruct C2 to generate the os::breakpoint. It has no effect for C1.

        Currently, C1 has its own control option: C1Breakpoint. It will generate MacroAssembler::int3() at all VEPs of nmethods. On the other hand, BreakAtExecute appears in the compiler directives can be method-specific.

        C1 is capable of generating a LIR, but it's not in use right now.
        void breakpoint() { append(new LIR_Op0(lir_breakpoint)); }
