The Linux xfail decorator was removed in r272326 with the claim that the
test "runs reliably on the linux x86 buildbot." It also runs reliably on
FreeBSD for me.

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.
llvm-svn: 308905
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.

This works on SVN but is a bit fragile on the Swift branch.
I'm adding the test to both, so we have this path covered.

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.

Fails with all versions of arm/aarch64 gcc available on ubuntu 16.04/14.04.
Passes with Linaro GCC version >= 4.8 but fails with >= 5.0. But There are other regressions when we use Linaro GCC.

The debug info emitted by clang for static variables improved by
rL286302 and it exposed an incorrect test expactation because now LLDB
able to displays more data 9thanks to better debug info) then before.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

Clang on ARM64 was making the three Function methods with identical bodies have
one implementation that was shared. That threw off the count of breakpoints, since
we don't count as separate locations three functions with the same address.
I also cleaned up the test case while I was at it.

Summary:
referencing a user-defined operator new was triggering an assert in clang because we were
registering the function name as string "operator new", instead of using the special operator
enum, which clang has for this purpose. Method operators already had code to handle this, and now
I extend this to cover free standing operator functions as well. Test included.

It's always hard to remember when to include this file, and
when you do include it it's hard to remember what preprocessor
check it needs to be behind, and then you further have to remember
whether it's windows.h or win32.h which you need to include.
This patch changes the name to PosixApi.h, which is more appropriately
named, and makes it independent of any preprocessor setting.
There's still the issue of people not knowing when to include this,
because there's not a well-defined set of things it exposes other
than "whatever is missing on Windows", but at least this should
make it less painful to fix when problems arise.
This patch depends on LLVM revision r278170.

Summary:
One of the tests there does not work with gcc, so I'm spinning that off into a separate test, so
that we can XFAIL it with more granularity.
I am also renaming the test to reflect the fact that it no longer tests only integer arguments.

We were checking for integer types only before this. So I added the ability for CompilerType objects to check for integer and enum types.
Then I searched for places that were using the CompilerType::IsIntegerType(...) function. Many of these places also wanted to be checking for enumeration types as well, so I have fixed those places. These are in the ABI plug-ins where we are figuring out which arguments would go in where in regisers/stack when making a function call, or determining where the return value would live. The real fix for this is to use clang to compiler a CGFunctionInfo and then modify the code to be able to take the IR and a calling convention and have the backend answer the questions correctly for us so we don't need to create a really bad copy of the ABI in each plug-in, but that is beyond the scope of this bug fix.
Also added a test case to ensure this doesn't regress in the future.

Prior to this we would display the typename for "TestObj<-1>" as "TestObj<4294967295>" when we showed the type. Expression parsing could also fail because we would fail to find the mangled name when evaluating expressions.
The issue was we were losing the signed'ness of the template integer parameter in DWARFASTParserClang.cpp.

This enables a couple of tests which have been shown to run reliably on the
linux x86 buildbot. If you see a failure after this commit, feel free to add
the xfail back, but please make it as specific as possible (i.e., try to make
it not cover i386/x86_64 with clang-3.5, clang-3.9 or gcc-4.9).

If a lldbinline test's source file changed language, then the Makefile wasn't
updated. This was a problem if the Makefile was checked into the repository.
Now lldbinline.py always regenerates the Makefile and asserts if the
newly-generated version is not the same as the one already there. This ensures
that the repository will never be out of date without a buildbot failing.

Some compilers do not mark up C++ functions as extern "C" in the DWARF, so LLDB
has to fall back (if it is about to give up finding a symbol) to using the base
name of the function.
This fix also ensures that we search by full name rather than "auto," which
could cause unrelated C++ names to be found. Finally, it adds a test case.

Remove XFAIL from some tests that now pass.
Add XFAIL to some tests that now fail.
Fix a crasher where a null pointer check isn't guarded.
Properly handle all types of errors in SymbolFilePDB.
llvm-svn: 269454
1. Fixed semicolon placement in the lambda in the test itself.
2. Fixed lldbinline tests in general so that we don't attempt tests on platforms that don't use the given type of debug info. (For example, no DWO tests on Windows.) This fixes one of the two failures on Windows. (TestLambdas.py was the only inline test that wasn't XFailed or skipped on Windows.)
3. Set the error string in IRInterpreter::CanInterpret so that the caller doesn't print (null) instead of an explanation. I don't entirely understand the error, so feel free to suggest a better wording.
4. XFailed the test on Windows. The interpreter won't evaluate the lambda because the module has multiple function bodies. I don't exactly understand why that's a problem for the interpreter nor why the problem arises only on Windows.

In templated const functions, trying to run an expression would produce the
error
error: out-of-line definition of '$__lldb_expr' does not match any declaration
in 'foo' member declaration does not match because it is const qualified
error: 1 error parsing expression
which is no good. It turned out we don't actually need to worry about "const,"
we just need to be consistent about the declaration of the expression and the
FunctionDecl we inject into the class for "this."
Also added a test case.
