didn't need to be indexed.

Updated the MappedHash.h (generic Apple accelerator table) and the DWARF
specific one (HashedNameToDIE.h) to be up to date with the latest and
greatest hash table format.

Parameterize the iteration count used when running benchmarks, instead of hard-coded inside the test case.
Add a '-y count' option to the test driver for this purpose.  An example:

 $  ./dotest.py -v -y 25 +b -p TestDisassembly.py

bring the debugger to the desired state.

This patch makes BenchBase inherit from TestBase, instead of Base (which is a parent class of
TestBase).  This is so that we can also enjoy the Pythonic way of bringing the lldb debugger
to a desired state before running the benchmark and collect statistics.

to use the "const char *".

Also modified the expression parser to not crash when a function type fails
to copy into the expression AST context.

process IDs, and thread IDs, but was mainly needed for for the UserID's for
Types so that DWARF with debug map can work flawlessly. With DWARF in .o files
the type ID was the DIE offset in the DWARF for the .o file which is not
unique across all .o files, so now the SymbolFileDWARFDebugMap class will
make the .o file index part (the high 32 bits) of the unique type identifier
so it can uniquely identify the types.

    child=None, child_prompt=None, use_cmd_api=False

By default, expect a pexpect spawned child and child prompt to be
supplied (use_cmd_api=False).  If use_cmd_api is true, ignore the child
and child prompt and use self.runCmd() to run the hooks one by one.

Modify existing client to reflect the change.

so we don't have to lookup types in a type list by ID.

Changed the DWARF parser to remove the "can externally complete myself" bits
from the type when we are in the process of completing the type itself to
avoid an onslaught of external visible decl requests from the 
clang::ExternalASTSource.

this patch introduces a new command script import command which takes as input a filename for a Python script and imports the module contained in that file. the containing directory is added to the Python path such that dependencies are honored. also, the module may contain an __lldb_init_module(debugger,dict) function, which gets called after importing, and which can somehow initialize the module's interaction with lldb

    watchpoint modify -c 'global==5'

modifies the last created watchpoint so that the condition expression
is evaluated at the stop point to decide whether we should proceed with
the stopping.

Also add SBWatchpont::SetCondition(const char *condition) to set condition
programmatically.

Test cases to come later.

out the latest LLDB, LLVM and Clang and makes sure
they work okay together.  The buildbot is currently
Mac OS X only because it uses xcodebuild.

Right now, the portion that runs the LLDB test
suite is commented out because of code-signing
problems (specifically, on Mac OS 10.7 a UI dialog
appears asking for the user's permission to attach
to the inferior process).

You can use the buildbot like this:

./scripts/buildbot.py -b /tmp/lldb-build -l /tmp/lldb.log

/tmp/lldb-build and /tmp/lldb.log should not exist
when the script is run.

/tmp/lldb-build is a temporary directory and is
removed at the end of a normal execution.

/tmp/lldb.log is a log file that sticks around.

The buildbot does not require built versions of anything;
it will do the building itself.
