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that the repository will never be out of date without a buildbot failing.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.

Summary:
using stdio in tests does not work on windows, and it is not completely reliable on linux.
Avoid using stdio in this test, as it is not necessary for this purpose.

TestBSDArchives.py and TestWatchLocation.py fail due to unicode error and bug has already been reported for arm and macOSx.
TestConstVariables.py fails because lldb cant figure out frame variable type when used in expr.

m_decl_objects is problematic because it assumes that each VarDecl has a unique
variable associated with it. This is not the case in inline contexts.
Also the information in this map can be reconstructed very easily without
maintaining the map. The rest of the testsuite passes with this cange, and I've
added a testcase covering the inline contexts affected by this.

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.

This reverts commit r267833 as it breaks the build. It looks like some work in progress got

whole patch and let author resumbit it after fixing the build error.

Some older versions of clang emitted bit offsets that were negative and these bitfields would have their bitfield-ness stripped off and it would cause a clang assertion in clang assertions were enabled. I updated the bitfield C test to make sure we don't regress.

A number of test cases were failing on big-endian systems simply due to
byte order assumptions in the tests themselves, and no underlying bug
in LLDB.
These two test cases:
tools/lldb-server/lldbgdbserverutils.py
python_api/process/TestProcessAPI.py
actually check for big-endian target byte order, but contain Python errors
in the corresponding code paths.
These test cases:
functionalities/data-formatter/data-formatter-python-synth/TestDataFormatterPythonSynth.py
functionalities/data-formatter/data-formatter-smart-array/TestDataFormatterSmartArray.py
functionalities/data-formatter/synthcapping/TestSyntheticCapping.py
lang/cpp/frame-var-anon-unions/TestFrameVariableAnonymousUnions.py
python_api/sbdata/TestSBData.py (first change)
could be fixed to check for big-endian target byte order and update the
expected result strings accordingly. For the two synthetic tests, I've
also updated the source to make sure the fake_a value is always nonzero
on both big- and little-endian platforms.
These test case:
python_api/sbdata/TestSBData.py (second change)
functionalities/memory/cache/TestMemoryCache.py
simply accessed memory with the wrong size, which wasn't noticed on LE
but fails on BE.

This test sets the compiler optimization level to -O1 and
makes some assumptions about how local frame vars will be
stored (i.e. in registers). These assumptions are not always
true.
I did a first-pass set of improvements that:
(1) no longer assumes that every one of the target locations has
every variable in a register. Sometimes the compiler
is even smarter and skips the register entirely.
(2) simply expects one of the 5 or so variables it checks
to be in a register.
This test probably passes on a whole lot more systems than it
used to now. This is certainly true on OS X.
