Centralized a lot of the status information for processes,
threads, and stack frame down in the lldb_private::Process,
lldb_private::Thread, lldb_private::StackFrameList and the
lldb_private::StackFrame classes. We had some command line
commands that had duplicate versions of the process status
output ("thread list" and "process status" for example).
Removed the "file" command and placed it where it should
have been: "target create". Made an alias for "file" to
"target create" so we stay compatible with GDB commands.
We can now have multple usable targets in lldb at the
same time. This is nice for comparing two runs of a program
or debugging more than one binary at the same time. The
new command is "target select <target-idx>" and also to see
a list of the current targets you can use the new "target list"
command. The flow in a debug session can be:
(lldb) target create /path/to/exe/a.out
(lldb) breakpoint set --name main
(lldb) run
... hit breakpoint
(lldb) target create /bin/ls
(lldb) run /tmp
Process 36001 exited with status = 0 (0x00000000)
(lldb) target list
Current targets:
target #0: /tmp/args/a.out ( arch=x86_64-apple-darwin, platform=localhost, pid=35999, state=stopped )
* target #1: /bin/ls ( arch=x86_64-apple-darwin, platform=localhost, pid=36001, state=exited )
(lldb) target select 0
Current targets:
* target #0: /tmp/args/a.out ( arch=x86_64-apple-darwin, platform=localhost, pid=35999, state=stopped )
target #1: /bin/ls ( arch=x86_64-apple-darwin, platform=localhost, pid=36001, state=exited )
(lldb) bt
* thread #1: tid = 0x2d03, 0x0000000100000b9a a.out`main + 42 at main.c:16, stop reason = breakpoint 1.1
frame #0: 0x0000000100000b9a a.out`main + 42 at main.c:16
frame #1: 0x0000000100000b64 a.out`start + 52
Above we created a target for "a.out" and ran and hit a
breakpoint at "main". Then we created a new target for /bin/ls
and ran it. Then we listed the targest and selected our original
"a.out" program, so we showed two concurent debug sessions
going on at the same time.

Added auto completion for architecture names and for platforms.
Modified the OptionGroupOptions to be able to specify only some of the options that should be appended by using the usage_mask in the group defintions and also provided a way to remap them to a new usage mask after the copy. This allows options to be re-used and also targetted for specific option groups. Modfied the CommandArgumentType to have a new eArgTypePlatform enumeration. Taught the option parser to be able to automatically use the appropriate auto completion for a given options if nothing is explicitly specified in the option definition. So you don't have to specify it in the option definition tables. Renamed the default host platform name to "host", and the default platform hostname to be "localhost". Modified the "file" and "platform select" commands to make sure all options and args are good prior to creating a new platform. Also defer the computation of the architecture in the file command until all options are parsed and the platform has either not been specified or reset to a new value to avoid computing the arch more than once. Switch the PluginManager code over to using llvm::StringRef for string comparisons and got rid of all the AccessorXXX functions in lieu of the newer mutex + collection singleton accessors. llvm-svn: 129483 |

Added two new classes for command options:
lldb_private::OptionGroup
lldb_private::OptionGroupOptions
OptionGroup lets you define a class that encapsulates settings that you want
to reuse in multiple commands. It contains only the option definitions and the
ability to set the option values, but it doesn't directly interface with the
lldb_private::Options class that is the front end to all of the CommandObject
option parsing. For that the OptionGroupOptions class can be used. It aggregates
one or more OptionGroup objects and directs the option setting to the
appropriate OptionGroup class. For an example of this, take a look at the
CommandObjectFile and how it uses its "m_option_group" object shown below
to be able to set values in both the FileOptionGroup and PlatformOptionGroup
classes. The members used in CommandObjectFile are:
OptionGroupOptions m_option_group;
FileOptionGroup m_file_options;
PlatformOptionGroup m_platform_options;
Then in the constructor for CommandObjectFile you can combine the option
settings. The code below shows a simplified version of the constructor:
CommandObjectFile::CommandObjectFile(CommandInterpreter &interpreter) :
CommandObject (...),
m_option_group (interpreter),
m_file_options (),
m_platform_options(true)
{
m_option_group.Append (&m_file_options);
m_option_group.Append (&m_platform_options);
m_option_group.Finalize();
}
We append the m_file_options and then the m_platform_options and then tell
the option group the finalize the results. This allows the m_option_group to
become the organizer of our prefs and after option parsing we end up with
valid preference settings in both the m_file_options and m_platform_options
objects. This also allows any other commands to use the FileOptionGroup and
PlatformOptionGroup classes to implement options for their commands.
Renamed:
virtual void Options::ResetOptionValues();
to:
virtual void Options::OptionParsingStarting();
And implemented a new callback named:
virtual Error Options::OptionParsingFinished();
This allows Options subclasses to verify that the options all go together
after all of the options have been specified and gives the chance for the
command object to return an error. It also gives a chance to take all of the
option values and produce or initialize objects after all options have
completed parsing.
Modfied:
virtual Error
SetOptionValue (int option_idx, const char *option_arg) = 0;
to be:
virtual Error
SetOptionValue (uint32_t option_idx, const char *option_arg) = 0;
(option_idx is now unsigned).

Added more platform support. There are now some new commands:
platform status -- gets status information for the selected platform platform create <platform-name> -- creates a new instance of a remote platform platform list -- list all available platforms platform select -- select a platform instance as the current platform (not working yet) When using "platform create" it will create a remote platform and make it the selected platform. For instances for iPhone OS debugging on Mac OS X one can do: (lldb) platform create remote-ios --sdk-version=4.0 Remote platform: iOS platform SDK version: 4.0 SDK path: "/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0" Not connected to a remote device. (lldb) file ~/Documents/a.out Current executable set to '~/Documents/a.out' (armv6). (lldb) image list [ 0] /Volumes/work/gclayton/Documents/devb/attach/a.out [ 1] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/dyld [ 2] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/libSystem.B.dylib Note that this is all happening prior to running _or_ connecting to a remote platform. Once connected to a remote platform the OS version might change which means we will need to update our dependecies. Also once we run, we will need to match up the actualy binaries with the actualy UUID's to files in the SDK, or download and cache them locally. This is just the start of the remote platforms, but this modification is the first iteration in getting the platforms really doing something. llvm-svn: 127934 |
