Refactorings of watchpoint creation APIs so that SBTarget::WatchAddress(), SBValue::Watch(), and SBValue::WatchPointee()
now take an additional 'SBError &error' parameter (at the end) to contain the reason if there is some failure in the
operation. Update 'watchpoint set variable/expression' commands to take advantage of that.
Update existing test cases to reflect the API change and add test cases to verify that the SBError mechanism works for
SBTarget::WatchAddress() by passing an invalid watch_size.

boxed expressions returning numbers and strings.
I also added boxed expressions to our testcases, and
enabled boxed expressions when libarclite is linked into
the inferior.
llvm-svn: 157026
Also changed the defaults for SBThread::Step* to not delete extant plans.
Also added some test cases to test more complex stepping scenarios.

Switch over to the "*-apple-macosx" for desktop and "*-apple-ios" for iOS triples.
Also make the selection process for auto selecting platforms based off of an arch much better.
llvm-svn: 156354
Cleaned up the lldb.utils.symbolication, lldb.macosx.heap and lldb.macosx.crashlog. The lldb.macosx.heap can now build a dylib for the current triple into a temp directory and use it from there.

We are introducing a new Logger class on the Python side. This has the same purpose, but is unrelated, to the C++ logging facility
The Pythonic logging can be enabled by using the following scripting commands:
(lldb) script Logger._lldb_formatters_debug_level = {0,1,2,...}
0 = no logging
1 = do log
2 = flush after logging each line - slower but safer
3 or more = each time a Logger is constructed, log the function that has created it
more log levels may be added, each one being more log-active than the previous
by default, the log output will come out on your screen, to direct it to a file:
(lldb) script Logger._lldb_formatters_debug_filename = 'filename'
that will make the output go to the file - set to None to disable the file output and get screen logging back
Logging has been enabled for the C++ STL formatters and for Cocoa class NSData - more logging will follow
synthetic children providers for classes list and map (both libstdcpp and libcxx) now have internal capping for safety reasons
this will fix crashers where a malformed list or map would not ever meet our termination conditions
to set the cap to a different value:
(lldb) script {gnu_libstdcpp|libcxx}.{map|list}_capping_size = new_cap (by default, it is 255)
you can optionally disable the loop detection algorithm for lists
(lldb) script {gnu_libstdcpp|libcxx}.list_uses_loop_detector = False

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.
llvm-svn: 153563
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

Patched LLVM to handle generic i386 relocations.
This avoids some sudden termination problems on
i386 where the JIT would exit() out reporting
"Invalid CPU type!"
llvm-svn: 153467
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.

relocations (LLVM revision 153147). Now when
we report section locations in the target process,
LLVM will apply both those relocations whose
targets are in that section and those relocations
which reside in that section and point to other
sections.

Changes to synthetic children:
- the update(self): function can now (optionally) return a value - if it returns boolean value True, ValueObjectSyntheticFilter will not clear its caches across stop-points
this should allow better performance for Python-based synthetic children when one can be sure that the child ValueObjects have not changed
- making a difference between a synthetic VO and a VO with a synthetic value: now a ValueObjectSyntheticFilter will not return itself as its own synthetic value, but will (correctly)
claim to itself be synthetic
- cleared up the internal synthetic children architecture to make a more consistent use of pointers and references instead of shared pointers when possible
- major cleanup of unnecessary #include, data and functions in ValueObjectSyntheticFilter itself
- removed the SyntheticValueType enum and replaced it with a plain boolean (to which it was equivalent in the first place)
Some clean ups to the summary generation code
Centralized the code that clears out user-visible strings and data in ValueObject
More efficient summaries for libc++ containers
llvm-svn: 153061
- Clang now completes all Objective-C objects (if
they are not already complete, and they have
external lexical sources) during structure
layout, avoiding a LLDB crash.
- The Clang Decl printer handles reference types
correctly. This prevents LLDB from crashing
when expression logging is enabled.
