from a process and hooked it up to the new packet that was recently added to our GDB remote executable named debugserver. Now Process has the following new calls: virtual Error Process::GetMemoryRegionInfo (lldb::addr_t load_addr, MemoryRegionInfo &range_info); virtual uint32_t GetLoadAddressPermissions (lldb::addr_t load_addr); Only the first one needs to be implemented by subclasses that can add this support. Cleaned up the way the new packet was implemented in debugserver to be more useful as an API inside debugserver. Also found an error where finding a region for an address actually will pick up the next region that follows the address in the query so we also need ot make sure that the address we requested the region for falls into the region that gets returned. llvm-svn: 144976
