Jason Molenda 52560ba105 Change TestExec.py from creating an i386+x86_64 fat binary
on darwin systems and re-execing itself, to creating two
separate test programs; lldb runs the first program and it
exec's the second.  

Support for compiling for i386 is going away.

Stella Stamenova 9d6fabf9e3 [lit] Split test_set_working_dir TestProcessLaunch into two tests and fix it on Windows
Summary:
test_set_working_dir was testing two scenario: failure to set the working dir because of a non existent directory and succeeding to set the working directory. Since the negative case fails on both Linux and Windows, the positive case was never tested. I split the test into two which allows us to always run both the negative and positive cases. The positive case now succeeds on Linux and the negative case still fails.
During the investigation, it turned out that lldbtest.py will try to execute a process launch command up to 3 times if the command failed. This means that we could be covering up intermittent failures by running any test that does process launch multiple times without ever realizing it. I've changed the counter to 1 (though it can still be overwritten with the environment variable).
This change also fixes both the positive and negative cases on Windows. There were a few issues:
1) In ProcessLauncherWindows::LaunchProcess, the error was not retrieved until CloseHandle was possibly called. Since CloseHandle is also a system API, its success would overwrite any existing error that could be retrieved using GetLastError. So by the time the error was retrieved, it was now a success.
2) In DebuggerThread::StopDebugging TerminateProcess was called on the process handle regardless of whether it was a valid handle. This was causing the process to crash when the handle was LLDB_INVALID_PROCESS (0xFFFFFFFF).
3) In ProcessWindows::DoLaunch we need to check that the working directory exists before launching the process to have the same behavior as other platforms which first check the directory and then launch process. This way we also control the exact error string.

Pavel Labath 0e33a0cd58 DebugNamesDWARFIndex: Implement DWARFDeclContext variant of GetTypes method
This method is used to find complete definitions of a type when one

Since it is only accessed from DWARFASTParserClang, it was not

Leonard Mosescu e1bb51789d Add a new SBTarget::LoadCore() overload which surfaces errors if the load fails
There was no way to find out what's wrong if SBProcess SBTarget::LoadCore(const char *core_file) failed. 
Additionally, the implementation was unconditionally setting sb_process, so it wasn't even possible to check if the return SBProcess is valid.

This change adds a new overload which surfaces the errors and also returns a valid SBProcess only if the core load succeeds:

SBProcess SBTarget::LoadCore(const char *core_file, SBError &error);

Pavel Labath 663773857f dotest: make inline tests compatible with -f
Summary:
This is split off from D47265 where I needed to be able to invoke every test
with -f. That patch is kinda dead now, but this part seems like a good
cleanup anyway.

The problem with inline tests was in the way we were adding methods to
the class, which left them with an incorrect __name__ property. This
prevented dotest from finding them with -f.

I fix this with (what I think is) the correct way of dynamically
creating classes -- passing the list of methods during type construction
instead of fixing up the class afterwards. Among other things this has
the advantage of not needing to do anything special for debug info
variants. As our test method will be visible to the metaclass, it will
automagically do the multiplication for us.

James Y Knight 9c2d52014c Fix support for distinguishing archive members by timestamp on Darwin.
On Darwin, the binary's symbol table points to debug info in object
files -- potentially object files within a static library. Such a
library may have multiple entries with the same name, distinguished
only by timestamp.

The code was already _attempting_ to handle this case (see the code in
ObjectContainerBSDArchive::Archive::FindObject which disambiguates via
timestamp). But, unfortunately, while the timestamp was taken into
account on the _first_ lookup, the result was then cached in a map
keyed only off of the path.

Added the timestamp to the cache, and added a test case.

Frederic Riss 9cd4def1c6 Fix Module::FindTypes to return the correct number of matches.
In r331719, I changed Module::FindTypes not to limit the amount
of types returned by the Symbol provider, because we want all
possible matches to be able to filter them. In one code path,
the filtering was applied to the TypeList without changing the
number of types that gets returned. This is turn could cause
consumers to access beyond the end of the TypeList.

This patch fixes this case and also adds an assertion to
TypeList::GetTypeAtIndex to catch those obvious programming
mistakes.

Triggering the condition in which we performed the incorrect
access was not easy. It happened a lot in mixed Swift/ObjectiveC
code, but I was able to trigger it in pure Objective C++ although
in a contrieved way.

Frederic Riss 1739b7d076 Really test type lookup in TestCppTypeLookup.py
Summary:
... and fix one bug found this way. Currently, the test works not because
types are looked up correctly, but because by injecting local variables
we also materialize the types for Clang. If we disable the local variable
injection, then one check fails.

The reason of the failure is that FindTypes is run with max_matches==1
and this value is passed down to the symbol lookup functions. When the
search is performed only on the basename (like it's the case for an
entity defined in the root namespace), then the search will stop after
having found one match on the basename. But that match might be in a
namespace, we were really just looking up the basename in the accelerator
tables.

The solution is to not pass max_matches down, but to search without a
limit and let RemoveMismatchedTypes do its job afterwards. Note the
patch includes 2 hunks with the same change, but only the latter is
tested. I couldn't find a way to create a testcase for the other
branch of the if ('image lookup -t' allows me to get there, but it
only ever returns one type anyway).

Jason Molenda b81afd6598 Fix the .experimental. settings feature so that we don't return an error
if an experimental setting has been removed/is missing.

Add tests for the .experimental. settings behaviors -- that they correctly
forward through to the real setting if it has become a real setting,
that they don't generate errors when a settig has been removed.

As Pavel notes in https://reviews.llvm.org/D45348, the way I'm suppressing
errors in the setting is not completely correct - if any of the setting
path components include "experimental", a missing setting would be declared
a non-error.  So

settings set target.experimental.setting-that-does-not-exist true

would not generate an error, which is correct.  But as Pavel notes, 

settings set setting-does-not-exist.experimental.run-stopped true

should generate an error because the unknown name occurs before the
"experimental".  The amount of change to do this correctly hasn't

This fixes a bug where

  (lldb) target var g_ptr

would populate the global variables list with exactly one entry
because SymbolFileDWARF::ParseVariables() was invoked with a list of
DIEs pre-filtered by name, such that a subsequent call to

  (lldb) fr var --show-globals

would only list that one variable, because CompileUnit::m_variables
was already initialized, fooling CompileUnit::GetVariableList().

CompileUnit::GetVariableList() grabs the *complete* list of variables
via (SymbolFileDWARF, ...)::ParseVariablesForContext and that still
calls CompileUnit::SetVariableList(variables) which acts as the
caching mechanism.
