I believe that PTRACE_GETHBPREGS with a value of 0 returns that hardware stoppoint info on arm, and the byte representing the number of available hardware watchpoints will be 0 if they aren't supported. Not sure if there's a simpler way. https://reviews.llvm.org/D24629 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
