Fixing an issue where Unicode characters in an NSString were printed as escape sequences by the summary provider shipping with LLDB - Added relevant test case code. Bonus points for identifying the source of the quotes :-)

Fixing an issue where saying 'po foo' made both the summary and the description for foo come out. If one is po'ing something they most probably only care about the description - We will not omit the summary

Converted commented out printf statements for dynamic type logging to use the log for "log enabe lldb types".

with recent Clang.  Clang is now stricter about
presence of complete types and about use of the
"template" keyword in C++ for template-dependent
types.

indicates that the section is thread specific. Any functions the load a module
given a slide, will currently ignore any sections that are thread specific.

lldb_private::Section now has:

bool
Section::IsThreadSpecific () const
{
    return m_thread_specific;
}

void
Section::SetIsThreadSpecific (bool b)
{
    m_thread_specific = b;
}

The ELF plug-in has been modified to set this for the ".tdata" and the ".tbss"
sections.

Eventually we need to have each lldb_private::Thread subclass be able to 
resolve a thread specific section, but for now they will just not resolve. The
code for that should be trivual to add, but the address resolving functions
will need to be changed to take a "ExecutionContext" object instead of just
a target so that thread specific sections can be resolved.

1 - sections only get a valid VM size if they have SHF_ALLOC in the section flags
2 - symbol names are marked as mangled if they start with "_Z"

Also fixed the DWARF parser to correctly use the section file size when extracting the DWARF.

Synthetic values are now automatically enabled and active by default. SBValue is set up to always wrap a synthetic value when one is available.
A new setting enable-synthetic-value is provided on the target to disable this behavior.
There also is a new GetNonSyntheticValue() API call on SBValue to go back from synthetic to non-synthetic. There is no call to go from non-synthetic to synthetic.
The test suite has been changed accordingly.
Fallout from changes to type searching: an hack has to be played to make it possible to use maps that contain std::string due to the special name replacement operated by clang
Fixing a test case that was using libstdcpp instead of libc++ - caught as a consequence of said changes to type searching

llvm-svn: 153495

Fixed type lookups to "do the right thing". Prior to this fix, looking up a type using "foo::bar" would result in a type list that contains all types that had "bar" as a basename unless the symbol file was able to match fully qualified names (which our DWARF parser does not). 

This fix will allow type matches to be made based on the basename and then have the types that don't match filtered out. Types by name can be fully qualified, or partially qualified with the new "bool exact_match" parameter to the Module::FindTypes() method.

This fixes some issue that we discovered with dynamic type resolution as well as improves the overall type lookups in LLDB.

If creation of watchpoint failed on the device, make sure the list maintained by the target reflects that by cleaning it up.

Patched LLVM to handle generic i386 relocations.
This avoids some sudden termination problems on

"Invalid CPU type!"

Adding a new API call IsTypeComplete() to SBType. This call is meant to check if the type has been previously completed or not (which is mostly interesting from a performance point of view)

Adding a test case that checks that we do not complete types before due time. This should help us track cases similar to the cascading data formatters.

Fixed up the command so that it doesn't dump the first arguments when run from the command line which was causing this script to dump the script itself.

parse the output from "log enable --timestamp ...." and converts it to be relative
to the first timestamp and shows the time deltas between log lines. This can also
be used as a stand along script outside of lldb:

./delta.py log.txt

llvm-svn: 153288

Fixed a performance regression when dynamic types are enable where we would ask a C++ type if it can possibly be dynamic. Previously we would force the type to complete itself and then anwwer the question definitively. Now we ask the type if it is already complete and only definitively answer the question for completed types and just say "yes" for non-complete C++ types. We also always now answer yes for Objective C classes and do not complete those types either.

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.

This is the feature that allowed the user to have things like:

class Base { ... };
class Derived : public Base { ... };

and have formatters defined for Base work automatically for Derived.

This feature turned out to be too expensive since it requires completing types.

This patch takes care of removing cascading (other than typedefs chain cascading), updating the test suite accordingly, and adding required Cocoa class names to keep the AppKit formatters working

them both installed with the LLVM MC version being the default. I renamed the
name of the LLVM MC disassembler plug-in to "llvm-mc" and the LLVM enhanced
disassembly plug-in to "llvm-edis" and they can both be installed for now.

To use the "llvm-edis" disassembler, you can just specify it while disassembling:

(lldb) disassemble --plugin llvm-edis --name main
(lldb) disassemble --plugin llvm-mc --name main

This will allow us to compare the output of the two disassembler and eventually
deprecate the old one when the new one is ready. But it does use the new disassembler
by default so we continue to test it on a daily basis.

llvm-svn: 153231

However, the debugserver cannot get past the instruction which triggered the watchpoint.
So a workaround is in place for the time being which disables the triggered watchpoint
before resuming.

Lots of commented out printf's remain in the source which needs to be cleaned up.
