Greg Clayton 3bcdfc0ec1 <rdar://problem/12798131>
Cleaned up the option parsing code to always pass around the short options as integers. Previously we cast this down to "char" and lost some information. I recently added an assert that would detect duplicate short character options which was firing during the test suite.

This fix does the following:
- make sure all short options are treated as "int"
- make sure that short options can be non-printable values when a short option is not required or when an option group is mixed into many commands and a short option is not desired
- fix the help printing to "do the right thing" in all cases. Previously if there were duplicate short character options, it would just not emit help for the duplicates
- fix option parsing when there are duplicates to parse options correctly. Previously the option parsing, when done for an OptionGroup, would just start parsing options incorrectly by omitting table entries and it would end up setting the wrong option value

Jim Ingham 4f465cff8a Change the Thread constructor over to take a Process& rather than a ProcessSP. We can't create Threads with a NULL ProcessSP, so it makes no sense to use the SP.
Then make the Thread a Broadcaster, and get it to broadcast when the selected frame is changed (but only from the Command Line) and when Thread::ReturnFromFrame 
changes the stack.
Made the Driver use this notification to print the new thread status rather than doing it in the command.
Fixed a few places where people were setting their broadcaster class by hand rather than using the static broadcaster class call.

Jim Ingham cfc0935ed9 Added an lldb_private & equivalent SB API to send an AsyncInterrupt to the event loop.
Convert from calling Halt in the lldb Driver.cpp's input reader's sigint handler to sending this AsyncInterrupt so it can be handled in the 
event loop.
If you are attaching and get an async interrupt, abort the attach attempt.
Also remember to destroy the process if get interrupted while attaching.
Getting this to work also required handing the eBroadcastBitInterrupt in a few more places in Process WaitForEvent & friends.

Jim Ingham 64e7ead1d8 Clean up the usage of "MasterPlan" status in ThreadPlans. Only user-initiated plans
should be MasterPlans that want to stay on the plan stack.  So make all plans NOT
MasterPlans by default and then have the SB API's and the CommandObjectThread step
commands set this explicitly.

Also added a "clean up" phase to the Thread::ShouldStop so that if plans get stranded
on the stack, we can remove them.  This is done by adding an IsPlanStale method to the
thread plans, and if the plan can know that it is no longer relevant, it returns true,
and the plan and its sub-plans will get discarded.

Greg Clayton 4463399b0d Added a new packet to our GDB remote protocol:
QListThreadsInStopReply
	
This GDB remote query command can enable added a "threads" key/value pair to all stop reply packets so that we always get a list of all threads in each stop reply packet. It increases performance if enabled (the reply to the "QListThreadsInStopReply" is "OK") by saving us from sending to command/reply pairs (the "qfThreadInfo" and "qsThreadInfo" packets), and also helps us keep the current process state up to date.

Johnny Chen d45a9c32c2 Previous check-ins allow to hit the arm hardware watchpoint, with a workaound to handle the issue
that the inferior cannot execute past the watchpoint-triggering instruction.

The solution is disable the watchpoint before resuming the inferior and make it hardware single step;
when the inferior stops again due to single step, re-enable the watchpoint and disable the single step
to make the inferior able to continue again without obstacle.

Greg Clayton a9f7b79dfe <rdar://problem/10605072>
Added the ability to override command line commands. In some cases GUI interfaces
might want to intercept commands like "quit" or "process launch" (which might cause
the process to re-run). They can now do so by overriding/intercepting commands
by using functions added to SBCommandInterpreter using a callback function. If the
callback function returns true, the command is assumed to be handled. If false
is returned the command should be evaluated normally.

Adopted this up in the Driver.cpp for intercepting the "quit" command.

Greg Clayton d9e416c0ea The second part in thread hardening the internals of LLDB where we make
the lldb_private::StackFrame objects hold onto a weak pointer to the thread
object. The lldb_private::StackFrame objects the the most volatile objects
we have as when we are doing single stepping, frames can often get lost or
thrown away, only to be re-created as another object that still refers to the
same frame. We have another bug tracking that. But we need to be able to 
have frames no longer be able to get the thread when they are not part of
a thread anymore, and this is the first step (this fix makes that possible
but doesn't implement it yet).

Also changed lldb_private::ExecutionContextScope to return shared pointers to
all objects in the execution context to further thread harden the internals.

Greg Clayton 46fb558df1 Added optional calls to lldb_private::Process for getting memory region info
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.

Jason Molenda 3dc8583c96 Remove the QAddressIsExecutable packet I added last night.
Add a more general purpose qMemoryRegionInfo packet which can
describe various attributes about a memory region.  Currently it
will return the start address, size, and permissions (read, write,
executable) for the memory region.  It may be possible to add
additional attributes in the future such as whether the region is
designated as stack memory or jitted code a la vmmap.

I still haven't implemented the lldb side of the code to use this
packet yet so there may be unexpected behavior - but the basic implementation looks
about right.  I'll hook it up to lldb soon and fix any problems that crop up.

llvm-svn: 144175
2011-11-09 08:03:56 +00:00
Jason Molenda 1f3966bebd Add "QAddressIsExecutable" packet to debugserver. Used to test
whether a given address is in an executable region of memory or
not.  I haven't written the lldb side that will use this packet it
hasn't been tested yet but it's a simple enough bit of code.

I want to have this feature available for the unwinder code.  When
we're stopped at an address with no valid symbol context, there are
a number of questions I'd like to ask --

  is the current pc value in an executable region (e.g. did they
  jump to unallocated/unexecutable memory?  we know how to unwind
  from here if so.)

  Is the stack pointer or the frame pointer the correct register
  to use to find the caller's saved pc value?

Once we're past the first frame we can trust things like eh_frame
and ABI unwind schemes but the first frame is challenging and having
a way to check potential addresses to see if they're executable or
not would help narrow down the possibilities a lot.

Greg Clayton dce502ede0 Fixed the Xcode project building of LLVM to be a bit more user friendly:
- If you download and build the sources in the Xcode project, x86_64 builds
  by default using the "llvm.zip" checkpointed LLVM.
- If you delete the "lldb/llvm.zip" and the "lldb/llvm" folder, and build the
  Xcode project will download the right LLVM sources and build them from 
  scratch
- If you have a "lldb/llvm" folder already that contains a "lldb/llvm/lib"
  directory, we will use the sources you have placed in the LLDB directory.
  
Python can now be disabled for platforms that don't support it. 

Changed the way the libllvmclang.a files get used. They now all get built into
arch specific directories and never get merged into universal binaries as this
was causing issues where you would have to go and delete the file if you wanted
to build an extra architecture slice.

in order to distinguish the real single step exception from a watchpoint exception
which uses the same exc_type of EXC_BREAKPOINT and exc_code of EXC_I386_SGL.

This is done by checking the debug status register to find out whether the watchpoint
data break event has fired, and, if yes, stuff the data break address into the exception's
exc_sub_code field on the debugserver side for lldb to consume on the other end.
