Main changes in this patch include:
- cleanup plug-in interface and use ConstStrings for plug-in names
- Modfiied the BSD Archive plug-in to be able to pick out the correct .o file when .a files contain multiple .o files with the same name by using the timestamp
- Modified SymbolFileDWARFDebugMap to properly verify the timestamp on .o files it loads to ensure we don't load updated .o files and cause problems when debugging
The plug-in interface changes:
Modified the lldb_private::PluginInterface class that all plug-ins inherit from:
Changed:
virtual const char * GetPluginName() = 0;
To:
virtual ConstString GetPluginName() = 0;
Removed:
virtual const char * GetShortPluginName() = 0;
- Fixed up all plug-in to adhere to the new interface and to return lldb_private::ConstString values for the plug-in names.
- Fixed all plug-ins to return simple names with no prefixes. Some plug-ins had prefixes and most ones didn't, so now they all don't have prefixed names, just simple names like "linux", "gdb-remote", etc.

Allow command script import to load packages.
e.g.:
egranata$ ./lldb
(lldb) command script import lldb.macosx.crashlog
"crashlog" and "save_crashlog" command installed, use the "--help" option for detailed help
"malloc_info", "ptr_refs", "cstr_refs", and "objc_refs" commands have been installed, use the "--help" options on these commands for detailed help.
The "unwind-diagnose" command has been installed, type "help unwind-diagnose" for detailed help.
(lldb)
./lldb
(lldb) command script import theFoo
I am happy
(lldb) fbc
àèìòù
(lldb)
egranata$ ls theFoo/
__init__.py theBar.py
egranata$ cat theFoo/__init__.py
import lldb
import theBar
def __lldb_init_module(debugger, internal_dict):
print "I am happy"
debugger.HandleCommand("command script add -f theFoo.theBar.theCommand fbc")
return None
egranata$ cat theFoo/theBar.py
#encoding=utf-8
def theCommand(debugger, command, result, internal_dict):
result.PutCString(u"àèìòù")
return None

AppendMessage("") is called. This idiom is used in a handful of places
right now (e.g. to put space between different threads in 'bt all') but
the empty newline is being omitted instead of emitted.

std::string
Module::GetSpecificationDescription () const;
This returns the module as "/usr/lib/libfoo.dylib" for normal files (calls "std::string FileSpec::GetPath()" on m_file) but it also might include the object name in case the module is for a .o file in a BSD archive ("/usr/lib/libfoo.a(bar.o)"). Cleaned up necessary logging code to use it.

Patch by Yacine Belkadi!
When __GLIBC__ is defined, optind gets initialized to 0. So for the first parsed
option, parse_start is 0, too. If this option has no argument (Like "--continue"
of "process attach"), then the position stored is 0, instead of 1. This prevents
the completion later on in Options::HandleOptionCompletion() because the opt_pos
doesn't match the cursor_index.
Fix that by getting the option's position from the value of optind, as it's done
for the other types of options.
Re-enable test_process_attach_dash_dash_con() on Linux.
No regressions detected on Mac OS X (in TestCompletion.py)

LLDB now can use a single dash for all long options for all commands form the command line and from the command interpreter. This involved just switching all calls from getopt_long() to getopt_long_only().

Make lldb_private::RegularExpression thread safe everywhere. This was done by removing the m_matches array from the lldb_private::RegularExpression class and putting it into the new lldb_private::RegularExpression::Match class. When executing a regular expression you now have the option to create a lldb_private::RegularExpression::Match object and pass a pointer in if you want to get parenthesized matching. If you don't want any matching, you pass in NULL. The lldb_private::RegularExpression::Match object is initialized with the number of matches you desire. Any matching strings are now extracted from the lldb_private::RegularExpression::Match objects. This makes the regular expression objects thread safe and as a result many more regex objects were turned into static objects that end up using a local lldb_private::RegularExpression::Match object when executing.

Symbol table function names should support lookups like symbols with debug info.
To fix this I:
- Gutted the way FindFunctions is used, there used to be way too much smarts only in the DWARF plug-in
- Made it more efficient by chopping the name up once and using simpler queries so that SymbolFile and Symtab plug-ins don't need to do as much
- Filter the results at a higher level
- Make the lldb_private::Symtab able to chop up C++ mangled names and make as much sense out of them as possible and also be able to search by basename, fullname, method name, and selector name.

LLDB is crashing when logging is enabled from lldb-perf-clang. This has to do with the global destructor chain as the process and its threads are being torn down.
All logging channels now make one and only one instance that is kept in a global pointer which is never freed. This guarantees that logging can correctly continue as the process tears itself down.

With this notion, if parties outside the ScriptInterpreter itself need to acquire a lock on script APIs, they can do so by a pattern like this:
{
auto lock = interpeter->AcquireInterpreterLock();
// do whatever you need to do...
} // lock will automatically be released here
This might be useful for classes that use the Python convenience objects (e.g. PythonDictionary) to ensure they keep the underlying interpreter in a safe and controlled condition while they call through the C API functions
Of course, the ScriptInterpreter still manages its internal locking correctly when necessary :-)

ValueObjects themselves use DumpValueObjectOptions as the currency for the same purpose
The code to convert between these two units was replicated (to varying degrees of correctness) in several spots in the code
This checkin provides one and only one (and hopefully correct :-) entry point for this conversion

resolved command, which it should not do. It should adopt whatever context the
regular expression command was called with. This was causing regular expression
commands run inside breakpoint commands to adopt the currently selected context,
not the one coming from the breakpoint that we hit.

Made the "--reverse" option to "source list" also be able to use the "--count". This helps us implement support for regexp source list command:
(lldb) l -10
Which gets turned into:
(lldb) source list --reverse --count 10
Also simplified the code that is used to track showing more source from the last file and line.
llvm-svn: 176961
Calculate "can branch" using the MC API's rather than our hand-rolled regex'es.
As extra credit, allow setting the disassembly flavor for x86 based architectures to intel or att.

The notion of Crossref command has long been forgotten, and there is nothing using CommandObjectCrossref in the current LLDB codebase
However, this was causing a conflict with process plugins and command aliases ending up in an infinite loop under situations such as:
(lldb) command alias monitor process plugin packet monitor
(lldb) process att -n Calendar
Process 28709 stopped
Executable module set to "/Applications/Calendar.app/Contents/MacOS/Calendar".
Architecture set to: x86_64-apple-macosx.
(lldb) command alias monitor process plugin packet monitor
This fixes the loop (and consequent crash) by disposing of Crossref commands and related code

- generate-vers.pl has to be called by cmake to generate the version number
- parallel builds not yet supported; dependency on clang must be explicitly specified
Tested on Linux.
- Building on Mac will require code-signing logic to be implemented.
- Building on Windows will require OS-detection logic and some selective directory inclusion
Thanks to Carlo Kok (who originally prepared these CMakefiles for Windows) and Ben Langmuir
who ported them to Linux!

Be more user-friendly about not having scripting enabled:
a) if Python was built-out then tell people about it explicitly
b) if we are told to use none as a scripting language, then tell people about that too
This should limit the cases where the semi-cryptic error message "there is no embedded script interpreter in this mode." actually shows

Added a new "env" regular expression alias. If "env" is typed on its own "settings show target.env-vars" will be run. Otherwise it can be used to set and environment variable: "env FOO=BAR".

(lldb) b *0x1234
You can still of course just specify an address:
(lldb) b 0x1234
Also now we accept the '&' before function names to indicate to not to skip the function prologue like GDB supports. To see how this works:
(lldb) settings set interpreter.expand-regex-aliases 1
(lldb) b &main
breakpoint set --name 'main' --skip-prologue=0
Breakpoint 1: where = a.out`main at main.c:20, address = 0x0000000100000b60
(lldb) b main
breakpoint set --name 'main'
Breakpoint 2: where = a.out`main + 54 at main.c:21, address = 0x0000000100000b96
llvm-svn: 174695
Added a regular expression command called "_regexp-list" which mimics the GDB "line" command in the following forms:
LINENUM, to list around that line in current file,
FILE:LINENUM, to list around that line in that file,
FUNCTION, to list around beginning of that function,
*ADDRESS, to list around the line containing that address.
ADDRESS, same as above, but don't require a '*' as long as ADDRESS is hex
