Currently, lit tests don't set neither the module cache for building
inferiors nor the module cache used by lldb when running tests.
Furthermore, we have several places where we rely on the path to the
module cache being always the same, rather than passing the correct
value around. This makes it hard to specify a different module cache
path when debugging a a test.
This patch reworks how we determine and pass around the module cache
paths and fixes the omission on the lit side. It also adds a sanity
check to the lit and dotest suites.

read by dotest. This approach is deprecated, as stated in the dotest

This removes the curses result formatter which appears to be broken.
Passing --curses to dotest.py screws up my terminal and doesn't run any

Currently, we return all the entries such that their decl_ctx pointer >= decl_ctx provided.
Instead, we should return only the ones that decl_ctx pointer == decl_ctx provided.

Patch by Guilherme Andrade <guiandrade@google.com>.
llvm-svn: 370374
Summary:
The only reason for this function's existance is so that we could pass
the correct size into the DWARFExpression constructor. However, there is
no harm in passing the entire data extractor into the DWARFExpression,
since the same code is performing the size determination as well as the
subsequent parse. So, if we get malformed input or there's a bug in the
parser, we'd compute the wrong size anyway.
Additionally, reducing the number of entry points into the location list
parsing machinery makes it easier to switch the llvm debug_loc(lists)
parsers.
While inside, I added a couple of tests for invalid location list
handling.

This removes support for reading the LLDB_TEST_ARGUMENTS environment
variable and instead requires all arguments to be specified as part of
the invocation. This ensures that dotest.py invocations are easily

I was looking at the session directory logic for unrelated reasons and

Now that all supported build systems create a valid dotest.py
invocation, we no longer need to guess the directory where any of the
llvm tools live. Additionally, the current logic is incomplete: it
doesn't try to find any other tools than FileCheck, such as dsymutil for
example.
If no FileCheck is provided, we should print a warning and skip the
tests that need it, but that's not part of this patch.

This patch removes the -q (quiet) flag and changing the default
behavior. Currently the flag serves two purposes that are somewhat
contradictory, as illustrated by the difference between the argument
name (quiet) and the configuration flag (parsable). On the one hand it
reduces output, but on the other hand it prints more output, like the
result of individual tests. My proposal is to guard the extra output
behind the verbose flag and always print the individual test results.

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.

The refactoring patch for the option completion broke the completion
for ambiguous long options. As this feature was also untested (as
testing ambiguous options with the current test methods is impossible),
I just noticed now. This patch restores the old behavior and adds a

A new SPI was added to the objc runtime to get class names without
any demangling; AppleObjCRuntimeV2::ParseClassInfoArray was using
the original prototype name but had not been updated for the final
name yet, so lldb was falling back to the old function and doing
extra work for classes that were demangled. This commit fixes that.

Setting DYLD_INSERT_LIBRARIES to the Asan runtime and DYLD_LIBRARY_PATH
to the LLVM shared library dir causes the test suite to crash with a
segfault. We see this on the LLDB sanitized bot [1] on GreenDragon. I've
spent some time investigating, but I'm not sure what's going on (yet).
Originally I thought this was because we were building compiler-rt and
were loading an incompatible, just-built Asan library. However, the
issue persists even without compiler-rt. It doesn't look like the Asan
runtime is opening any other libraries that might be found in LLVM's
shared library dir and talking to the team confirms that. Another
possible explanation is that we're loading lldb form a place we don't
expect, but that doesn't make sense either, because DYLD_LIBRARY_PATH is
always set without the crash. I tried different Python versions and
interpreters but the issue persist.
As a (temporary?) workaround I propose not setting DYLD_LIBRARY_PATH
when DYLD_INSERT_LIBRARIES is set so we can turn the Asan bot on again
and get useful results.

pexpect gives as raw data going to a terminal. This means that if the
completed line does not fit the emulated line, the returned data will
contain line breaks. On my machine these line breaks happened to be
inside the "iohandler/completion" string that the test was searching
for.
Work around this by telling pexpect to emulate a very wide terminal.

Otherwise dotest doesn't run the test and just lets it always pass.

There are numorous flaws about the name conflict handling, this patch
attempts fixes them. Changes in details:
* HandleNameConflict return with a false DeclarationName
Hitherto we effectively never returned with a NameConflict error, even
if the preceding StructuralMatch indicated a conflict.
Because we just simply returned with the parameter `Name` in
HandleNameConflict and that name is almost always `true` when converted to
`bool`.
* Add tests which indicate wrong NameConflict handling
* Add to ConflictingDecls only if decl kind is different
Note, we might not indicate an ODR error when there is an existing record decl
and a enum is imported with same name. But there are other cases. E.g. think
about the case when we import a FunctionTemplateDecl with name f and we found a
simple FunctionDecl with name f. They overload. Or in case of a
ClassTemplateDecl and CXXRecordDecl, the CXXRecordDecl could be the 'templated'
class, so it would be false to report error. So I think we should report a
name conflict error only when we are 100% sure of that. That is why I think it
should be a general pattern to report the error only if the kind is the same.
* Fix failing ctu test with EnumConstandDecl
In ctu-main.c we have the enum class 'A' which brings in the enum
constant 'x' with value 0 into the global namespace.
In ctu-other.c we had the enum class 'B' which brought in the same name
('x') as an enum constant but with a different enum value (42). This is clearly
an ODR violation in the global namespace. The solution was to rename the
second enum constant.
* Introduce ODR handling strategies

On the command line we usually insert a space after a completion to indicate that
the completion was successful. After the completion API refactoring, this also
happens with directories which essentially breaks file path completion (as
adding a space terminates the path and starts a new arg). This patch restores the old
behavior by again allowing partial completions. Also extends the iohandler
and SB API tests as the implementation for this is different in Editline
and SB API.

Summary:
The DWARFExpression methods have a lot of arguments. This removes two of
them by removing the ability to slice the expression via two offset+size
parameters. This is a functionality that it is not always needed, and
when it is, we already have a different handy way of slicing a data
extractor which we can use instead.
