This test streamlines our use of variables that are expected by
Makefile.rules throughout the test suite. Mostly it replaced
potentially dangerous overrides and updates of variables like CFLAGS
with safe assignments to variables reserved for this purpose like
CFLAGS_EXTRAS.

Summary:
Instead of each test case knowing its depth relative to the test root,
we can just have dotest add the folder containing Makefile.rules to the
include path.
This was motivated by r370616, though I have been wanting to do this
ever since we moved to building tests out-of-tree.
The only manually modified files in this patch are lldbinline.py and
plugins/builder_base.py. The rest of the patch has been produced by this
shell command:

Apparently inline tests stop running anything after an empty line
behind an self.expect, which is a very good approach that could
never cause people to write tests that never run.
This patch removes all the empty lines so that all this test
is actually run. Also fixes the broken expects that only passed
because they weren't run before.

Today I discovered the skipLongRunningTest decorator and to my surprise
all the tests were passing without the decorator. They don't seem to be
that expensive either, they take a few seconds but we have tests that
take much longer than that. As such I propose to remove the decorator
and enable them by default.

Summary:
Our IR rewriting infrastructure currently fails when it encounters a variable which has no metadata associated.
This causes dynamic_cast to fail as in this case IRForTarget considers the type info pointers ('@_ZTI...') to be
variables without associated metadata. As there are no variables for these internal variables, this is actually
not an error and dynamic_cast would work fine if we didn't throw this error.
This patch fixes this by removing this diagnostics code. In case we would actually hit a variable that has no
metadata (but is supposed to have), we still have the error in the expression log so this shouldn't make it
harder to diagnose any missing metadata errors.
This patch should fix dynamic_cast and also adds a bunch of test coverage to that language feature.

Summary:
The change https://reviews.llvm.org/D55575 modified ClangASTContext::CreateParameterDeclaration to call decl_ctx->addDecl(decl); this caused a regression since the existing code in DWARFASTParserClang::ParseChildParameters is called with the containing DeclContext. So when end up with cases where we are parsing a parameter for a member function and the parameter is added to the CXXRecordDecl as opposed to the CXXMethodDecl. This example is given in the regression test TestBreakpointInMemberFuncWNonPrimitiveParams.py which without this fix in a modules build leads to assert on setting a breakpoint in a member function with non primitive parameters. This scenario would be common when debugging LLDB or clang.

Summary:
We currently don't support offsetof in the expression evaluator as it is implemented as a macro
(which then calls __builtin_offsetof) in stddef.h. The best solution would be to include that
header (or even better, import Clang's builtin module), but header-parsing and
(cross-platform) importing modules is not ready yet.
Until we get this working with modules I would say we add the macro to our existing macro list
as we already do with other macros from stddef.h/stdint.h. We should be able to drop all of them
once we can import the relevant modules by default.

Add a function to flatten the nested aggregate type
Differential Revision: https://reviews.llvm.org/D62702
Patch by Wanyi Ye <kusmour@gmail.com>
llvm-svn: 362543
Summary:
In r259902, LLDB started injecting all the locals in every expression
evaluation. This fixed a bunch of issues, but also caused others, mostly
performance regressions on some codebases. The regressions were bad
enough that we added a setting in r274783 to control the behavior and
we have been shipping with the setting off to avoid the perf regressions.
This patch changes the logic injecting the local variables to only inject
the ones present in the expression typed by the user. The approach is
fairly simple and just scans the typed expression for every local name.
Hopefully this gives us the best of both world as it just realizes the
types of the variables really used by the expression.
Landing this requires the 2 other issues I pointed out today to be addressed
but I wanted to gather comments right away.

Summary:
When we encounter a templated function in the debug information, we
were creating an AST that looked like this:
FunctionTemplateDecl 0x12980ab90 <<invalid sloc>> <invalid sloc> foo<int>
|-TemplateTypeParmDecl 0x12980aad0 <<invalid sloc>> <invalid sloc> class depth 0 index 0 T
|-FunctionDecl 0x12980aa30 <<invalid sloc>> <invalid sloc> foo<int> 'int (int)' extern
| |-TemplateArgument type 'int'
| `-ParmVarDecl 0x12980a998 <<invalid sloc>> <invalid sloc> t1 'int'
`-FunctionDecl 0x12980aa30 <<invalid sloc>> <invalid sloc> foo<int> 'int (int)' extern
|-TemplateArgument type 'int'
`-ParmVarDecl 0x12980a998 <<invalid sloc>> <invalid sloc> t1 'int'
Note that the FunctionTemplateDecl has 2 children which are identical (as
in have the same address). This is not what Clang is doing:
FunctionTemplateDecl 0x7f89d206c6f8 </tmp/template.cpp:1:1, line:4:1> line:2:5 foo
|-TemplateTypeParmDecl 0x7f89d206c4a8 <line:1:10, col:19> col:19 referenced typename depth 0 index 0 T
|-FunctionDecl 0x7f89d206c660 <line:2:1, line:4:1> line:2:5 foo 'int (T)'
| `-ParmVarDecl 0x7f89d206c570 <col:9, col:11> col:11 t1 'T'
`-FunctionDecl 0x7f89d206cb60 <line:2:1, line:4:1> line:2:5 used foo 'int (int)'
|-TemplateArgument type 'int'
`-ParmVarDecl 0x7f89d206ca68 <col:9, col:11> col:11 t1 'int':'int'
The 2 chidlren are different and actually repesent different things: the first
one is the unspecialized version and the second one is specialized. (Just looking
at the names shows another major difference which is that we create the parent
with a name of "foo<int>" when it should be just "foo".)
The fact that we have those 2 identical children confuses the ClangImporter
and generates an infinite recursion (reported in https://llvm.org/pr41473).
We cannot create the unspecialized version as the debug information doesn't
contain a mapping from the template parameters to their use in the prototype.
This patch just creates 2 different FunctionDecls for those 2 children of the
FunctionTemplateDecl. This avoids the infinite recursion and allows us to
call functions. As the XFAILs in the added test show, we've still got issues
in our handling of templates. I believe they are mostly centered on the fact
that we create do not register "foo" as a template, but "foo<int>". This is
a bigger change that will need changes to the debug information generation.
I believe this change makes sense on its own.

Add a convenience 'expectedFailureNetBSD' decorator and mark all tests
currently failing on NetBSD with it. Also skip a few tests that hang
the test suite. This should establish a baseline for the test suite
and get us closer to enabling tests on buildbot. This will help us
catch regressions while we still have a lot of work to do to get tests
working.
It seems that there are also some flaky tests. I am going to address
them later on.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

This patch changes the behavior when printing C++ function references:
where we previously would get a <could not determine size>, there is
now a <no summary available>. It's not clear to me whether this is a
bug or an omission, but it's one step further than LLDB previously
got.
