Jonas Devlieghere 15eacd741f [Reproducers] Change how reproducers are initialized.
This patch changes the way the reproducer is initialized. Rather than
making changes at run time we now do everything at initialization time.
To make this happen we had to introduce initializer options and their SB
variant. This allows us to tell the initializer that we're running in
reproducer capture/replay mode.

Because of this change we also had to alter our testing strategy. We
cannot reinitialize LLDB when using the dotest infrastructure. Instead
we use lit and invoke two instances of the driver.

Another consequence is that we can no longer enable capture or replay
through commands. This was bound to go away form the beginning, but I
had something in mind where you could enable/disable specific providers.
However this seems like it adds very little value right now so the
corresponding commands were removed.

Finally this change also means you now have to control this through the
driver, for which I replaced --reproducer with --capture and --replay to
differentiate between the two modes.

Pavel Labath 10c63835ad Fix windows build broken by r347846
The changed order of includes caused compile errors on MSVC due to
snprintf macro definition. snprintf should available since VS2015, and
the rest of the code seems to be able to use snprintf just fine without
this macro, so this removes it from the lldb driver as well.

Pavel Labath 7b968969db Remove getopt includes from the driver
They are not needed now that we use LLVMOption for command-line parsing
thank you, Jonas).  This also allows us to avoid linking of lldbHost
into the driver which was breaking liblldb encapsulation.

(Technically, there is still a lldb/Host/windows/windows.h include which
is needed on windows, but this is a header-only wrapper for <windows.h>,
so it is not necessary to link lldbHost for that. But ideally, that
should go away too.)

Jonas Devlieghere cef2af0f3c [driver] Fix --core/-c and add test
Because the optarg variable was shadowed we didn't notice we weren't
extracting the value from the option. This patch fixes that and renames
the variable to prevent this from happening in the future.

I also added two tests to check the error output for --core and --file
when the given value doesn't exist.

Jonas Devlieghere 68ed93d252 [Reproducers] Improve reproducer API and add unit tests.
When I landed the initial reproducer framework I knew there were some
things that needed improvement. Rather than bundling it with a patch
that adds more functionality I split it off into this patch. I also
think the API is stable enough to add unit testing, which is included in
this patch as well.

Other improvements include:

 - Refactor how we initialize the loader and generator.
 - Improve naming consistency: capture and replay seems the least ambiguous.
 - Index providers by name and make sure there's only one of each.
 - Add convenience methods for creating and accessing providers.

Jonas Devlieghere 00eae5ea31 [Driver] Use libOption with tablegen.
This patch modifies the lldb driver to use libOption for option parsing.
It allows us to decouple option parsing from option processing which is
important when arguments affect initialization. This was previously not
possible because the debugger need to be initialized as some option
interpretation (like the scripting language etc) was handled by the
debugger, rather than in the driver.

Stefan Granitz 6e6b4ac18e [CMake] Streamline code signing for debugserver and pass entitlements to extended llvm_codesign
Summary:
Use llvm_codesign to sign debugserver with entitlements.
Set global LLVM_CODESIGNING_IDENTITY from LLDB_CODESIGN_IDENTITY (if given).
Pass through ENTITLEMENTS from add_lldb_executable to add_llvm_executable.
Handle reconfigurations correctly.

We have a lot of cases, make them explicit:

(1) build and sign debugserver, if all conditions apply:
* LLDB_NO_DEBUGSERVER=OFF (default)
* On Darwin: LLDB_USE_SYSTEM_DEBUGSERVER=OFF (default)
* On Darwin: LLVM_CODESIGNING_IDENTITY == lldb_codesign

(2) use system debugserver, if on Darwin and any of:
* LLDB_USE_SYSTEM_DEBUGSERVER=ON and found on system (explicit case)
* LLVM_CODESIGNING_IDENTITY != lldb_codesign and found on system (fallback case)

(3) debugserver will not be available, in case of:
* LLDB_NO_DEBUGSERVER=ON
* On Darwin: LLVM_CODESIGNING_IDENTITY != lldb_codesign and not found on system

(4) error state, in case of:
* LLDB_USE_SYSTEM_DEBUGSERVER=ON and not found on system
* LLDB_USE_SYSTEM_DEBUGSERVER=ON and LLDB_NO_DEBUGSERVER=ON

Jason Molenda a9796ede39 Enable listening for EXC_RESOURCE events, and format mach
event as a thread stop reason if we receive one, using 
some macros to decode the payload.  

Patch originally written by Fred Riss, with a few small changes
by myself.

Writing a test for this is a little tricky because the 
mach exception data interpretation relies on header macros
or function calls - it may change over time and writing
a gdb_remote_client test for this would break as older 
encoding interpretation is changed.  I'll tak with Fred
about this more, but neither of us has been thrilled with
the kind of tests we could write for it.

Reid Kleckner 4dc0b1ac60 Fix clang -Wimplicit-fallthrough warnings across llvm, NFC
This patch should not introduce any behavior changes. It consists of
mostly one of two changes:
1. Replacing fall through comments with the LLVM_FALLTHROUGH macro
2. Inserting 'break' before falling through into a case block consisting
   of only 'break'.

We were already using this warning with GCC, but its warning behaves
slightly differently. In this patch, the following differences are
relevant:
1. GCC recognizes comments that say "fall through" as annotations, clang
   doesn't
2. GCC doesn't warn on "case N: foo(); default: break;", clang does
3. GCC doesn't warn when the case contains a switch, but falls through
   the outer case.

I will enable the warning separately in a follow-up patch so that it can
be cleanly reverted if necessary.

Aleksandr Urakov 709426b33a [PDB] Restore AST from PDB symbols
Summary:
This patch adds an implementation of retrieving of declarations and declaration
contexts based on PDB symbols.

PDB has different type symbols for const-qualified types, and this
implementation ensures that only one declaration was created for both const
and non-const types, but creates different compiler types for them.

The implementation also processes the case when there are two symbols
corresponding to a variable. It's possible e.g. for class static variables,
they has one global symbol and one symbol belonging to a class.

PDB has no info about namespaces, so this implementation parses the full symbol
name and tries to figure out if the symbol belongs to namespace or not,
and then creates nested namespaces if necessary.

Jason Molenda b0d33e9b3c Re-instate a bit of code that was commented out in r188246 which
reads an ObjectFileMachO's string table in one chunk.  Originally
this was commented out because binaries in the system's shared cache
all share a mega-string table and so reading the entire mega-strtab
for each binary was a performance problem.

In the reinstated code, I add a check that the binary we're reading
from memory is not in the shared cache (there isn't a constant in
<mach-o/loader.h> for this bit yet; we hardcode the value in one
other place in ObjectFileMachO alread).  For binaries that we're
reading out of memory that are NOT in the shared cache, reading 
the string table in one chunk is a big performance improvement.

Also have debugserver send up the flags value for binaries in its
response to the jGetLoadedDynamicLibrariesInfos request.

lldb-framework truly does depend on lldb-suite (liblldb + related tools).

In this change I want to invert their dependency. This will mean that lldb and
finish_swig will depend on lldb-framework in a framework build, and lldb-suite
otherwise. Instead of adding conditional logic everywhere to handle this, I
introduce LLDB_SUITE_TARGET to handle it.
