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).

This patch fixes an issue where we weren't looking for exact matches in the expression parser and also fixed the type lookup logic in the Module.cpp. Tests added to make sure we don't regress.

Summary:
We would fail to resolve (and thus display the value of) any
templated type which contained a template template argument even
though we don't really use template arguments.
This patch adds minimal support for template template arguments,
but I doubt we need any more than that.

- use more goodies from Makefile.rules to correctly build a 32-bit
binary.
- avoid hardcoding typeof(nil) in the test.
This should partially fix the linux bot. There is still one assertion
failure remaining, which I'll have to investigate separately, as I am
not experiencing it locally.

New tests should run the make syntax voodoo $@ and $<
instead of hardcoding the names. We should also document
how to write one, it's on my list.

Instead of applying the sledgehammer of refusing to insert any
C++ symbol in the ASTContext, try to validate the decl if what
we have is an operator. There was other code in lldb which was
responsible for this, just not really exposed (or used) in this
codepath. Also, add a better/more comprehensive test.

Summary:
When in a gmodules-like debugging scenario, you can have a parent decl context
that gets imported from an external AST. When this happens, we must be careful
to complete this type before adding children to it, otherwise it sometimes
results in a crash.

gcc will say that the type of "this" is "T * const", clang "T *".
Compare the unqualified type names to erase the difference between the
two, as the constness is not a part of this test.
FWIW, I think that the gcc behavior makes more sense here.

There's a bug in FindTypes, it ignores the exact flag if you pass a name that doesn't begin with
:: and pass eTypeClassAny for the type.
In this case we always know that the name we get from the vtable name is absolute so we can
work around the bug by prepending the "::". This doesn't fix the FindTypes bug.

This patch is the result of a discussion on lldb-dev, see
http://lists.llvm.org/pipermail/lldb-dev/2018-January/013111.html for
background.
For each test (should be eventually: each test configuration) a
separate build directory is created and we execute
make VPATH=$srcdir/path/to/test -C $builddir/path/to/test -f $srcdir/path/to/test/Makefile -I $srcdir/path/to/test
In order to make this work all LLDB tests need to be updated to find
the executable in the test build directory, since CWD still points at
the test's source directory, which is a requirement for unittest2.
Although we have done extensive testing, I'm expecting that this first
attempt will break a few bots. Please DO NOT HESITATE TO REVERT this
patch in order to get the bots green again. We will likely have to
iterate on this some more.

TestLibcxxListLoop - fails because the evil "define private public"
trick does not work with gmodules. The purpose of the test is not to
test debug info parsing so I just mark it as no_debug_info_testcase.
In the long term it may be interesting to write a mock std::list which
will allow us to test bad inputs to data formatters more easily.
TestGModules - seems to be a genuine bug. Filed pr36107 and xfailed.

This test stresses expression evaluation support for template functions.
Currently the support is rudimentary, and running this test causes assertion
failures in clang. This test cannot be XFAIL'ed because the test harness
treats assertion failures as unexpected events. For now, the test must be
skipped.

This fixes a bug in -gmodules DWARF handling when debugging without a .dSYM bundle
that was particularly noticable when debugging LLVM itself.
Debugging without clang modules and DWO handling should be unaffected by this patch.

Two tests were failing because the debugger was picking up multiply
defined internal symbols from the system libraries. This is a bug, as
there should be no ambiguity because the tests are defining variables
with should shadow these symbols, but lldb is not smart enough to figure
that out.
I work around the issue by renaming the variables in these tests, and in
exchange I create a self-contained test which reproduces the issue
without depending on the system libraries.
This increases the predictability of our test suite.

I tested on x86-64 and Jason on embedded architectures.

Summary:
This flag is on by default for darwin and freebsd, but off for linux.
Without it, clang will sometimes not emit debug info for types like
std::string. Whether it does this, and which tests will fail because of
that depends on the linux distro and c++ library version.
A bunch of tests were already setting these flags manually, but here
instead I take a whole sale approach and enable this flag for all tests.
Any test which does not want to have this flag (right now we have one
such test) can turn it off explicitly via
CFLAGS_EXTRAS+=$(LIMIT_DEBUG_INFO_FLAGS)
This fixes a bunch of data formatter tests on red-hat.

This reapplies https://reviews.llvm.org/D35740 with a tweak to find
the section by name rather than type. Section types don't distinguish
between regular sections and their DWO counterparts.

The DWO handling code can get confused by clang modules which also use
skeleton CUs to point to the object file with the full debug
info. This patch detects whether an object is a "real" DWO or a clang
module and prevents LLDB from interpreting clang modules as DWO. This
fixes the regression in TestWithModuleDebugging.

Templates can end in parameter packs, like this
template <class T...> struct MyStruct
{ /*...*/ };
LLDB does not currently support these parameter packs;
it does not emit them into the template argument list
at all. This causes problems when you specialize, e.g.:
template <> struct MyStruct<int>
{ /*...*/ };
template <> struct MyStruct<int, int> : MyStruct<int>
{ /*...*/ };
LLDB generates two template specializations, each with
no template arguments, and then when they are imported
by the ASTImporter into a parser's AST context we get a
single specialization that inherits from itself,
causing Clang's record layout mechanism to smash its
stack.
This patch fixes the problem for classes and adds
tests. The tests for functions fail because Clang's
ASTImporter can't import them at the moment, so I've
xfailed that test.

Many times a user wants to access a type when there's a variable of
the same name, or a variable when there's a type of the same name.
Depending on the precise context, currently the expression parser
can fail to resolve one or the other.
This is because ClangExpressionDeclMap has logic to limit the
amount of information it searches, and that logic sometimes cuts
down the search prematurely. This patch removes some of those early
exits.
In that sense, this patch trades performance (early exit is faster)
for correctness.
I've also included two new test cases showing examples of this
behavior – as well as modifying an existing test case that gets it
wrong.
llvm-svn: 301273
The test fails because an older clang did not emit the required debug
info (I am not sure when this got added, but clang-3.7 certainly did not
work yet). The actual platform has nothing to do with this.
