Highlighing junk data on VSCode can send a query for evaluate which
fails. In particular cases on Windows, this the error message can end
up as a c-string of [-35,-35,-35,-35,...]. Attempting to emplace this
as the error message causes an assert failure.
Prior to emplacing the error message, confirm that it is valid UTF8 to
eliminate errors such as mentione above.

2. GCC doesn't warn on "case N: foo(); default: break;", clang does
3. GCC doesn't warn when the case contains a switch, but falls through

Differential Revision: https://reviews.llvm.org/D52069
llvm-svn: 342266
Summary:
This patch adds an implementation of retrieving of declarations and declaration
contexts based on PDB symbols.
PDB has different type symbols for const-qualified types, and this
implementation ensures that only one declaration was created for both const
and non-const types, but creates different compiler types for them.
The implementation also processes the case when there are two symbols
corresponding to a variable. It's possible e.g. for class static variables,
they has one global symbol and one symbol belonging to a class.
PDB has no info about namespaces, so this implementation parses the full symbol
name and tries to figure out if the symbol belongs to namespace or not,
and then creates nested namespaces if necessary.

llvm-svn: 333639
This teaches lldb-test how to launch a process, set up an IRMemoryMap,
and issue memory allocations in the target process through the map. This
makes it possible to test IRMemoryMap in a targeted way.
This has uncovered two bugs so far. The first bug is that Malloc
performs an adjustment on the pointer returned from AllocateMemory (for
alignment purposes) which ultimately allows overlapping memory regions
to be created. The second bug is that after most of the address space on
the host side is exhausted, Malloc may return the same address multiple
times. These bugs (and hopefully more!) can be uncovered and tested for
with targeted lldb-test commands.
At an even higher level, the motivation for addressing these bugs is
that they can lead to strange user-visible failures (e.g, variables
assume the wrong value during expression evaluation, or the debugger
crashes). See my third comment on this swift-lldb PR for an example:
https://github.com/apple/swift-lldb/pull/652
I hope lldb-test is the right place to add this testing harness. Setting
up a gtest-style unit test proved too cumbersome (you need to recreate
or mock way too much debugger state), as did writing end-to-end tests
(it's hard to write a test that actually hits a buggy path).
With lldb-test, it's easy to read/generate the test input and parse the
test output. I'll attach a simple "fuzz" tester which generates failing
test cases to the Phab review. Here's an example:
```
Command: malloc(size=1024, alignment=32)
Malloc: address = 0xca000
Command: malloc(size=64, alignment=16)
Malloc: address = 0xca400

Summary:
For lldb-server, it is sufficient to parse only the native object file
format for its target OS (no other file can be loaded into a running
process). This moves the object file initialization code into specific
initializer classes: lldb-test and liblldb get all object files;
lldb-server gets only one of them. For this to work, I've needed to
create a special SystemInitializer for use in lldb-server, instead of it
calling directly into the common one.
This reduces the size of lldb-server by about 2%, which is not
earth-shattering, but it's an easy win, and it helps.

This patch restructures part of LLDB's testing configuration:
1. I moved the test dependencies up the chain so every dotest dependency
becomes a lit dependency as well. It wouldn't make sense for dotest to
have other dependencies when it's being run by lit. Lit on the other
hand can still specify extra dependencies.
2. I replaced as much generator expressions with variables as possible.
This is consistent with the rest of LLVM and doesn't break generators
that support multiple targets (MSVC, Xcode). This wasn't a problem
before, but now we need to expand the dotest arguments in the lit
configuration and there's only one test suite even with multiple
targets.

no need anymore for it to located under `test/`.

Summary:
lldb-test already had the ability to dump all symbol information in a
module. This is interesting, but it can be too verbose, and it also does
not use the same APIs that lldb uses to query symbol information. The
last part is interesting to me now, because I am about to add DWARF v5
debug_names support, which needs to implement these APIs.
This patch adds a set of arguments to lldb-test, which modify it's
behavior from dumping all symbols to dumping only the requested
information:
- --find={function,namespace,type,variable} - search for the given
kind of objects.
- --name - the name to search for.
- --regex - whether to treat the "name" as a regular expression. This is
not available for all lookup types (we do not have the required APIs
for namespaces and types).
- --context - specifies the context, which can be used to restrict the
search. This argument takes a variable name (which must be defined and
be unique), and we then use the context that this variable is defined
in as the search context.
- --function-flags={auto,full,base,method,selector} - a set of flags to
further restrict the search for function symbols.
Together, these flags and their combinations cover the main SymbolFile
entry points which I will need to modify for the accelerator table
support, and so I plan to do most of the regression testing this way.
(I've also found this a useful tool for exploration of what the given
APIs are supposed to do.)
I add a couple of tests to demonstrate the usage of the usage of the
various options, and also an xfailed test which demonstrates a bug I
found while playing with this. The only requirement for these tests is
the presence of lld -- the should run on any platform which is able to
build lldb.
These tests use c++ code as input, but this isn't a requirement. It is also
possible to use IR, assembly or json to create the test module.

The Args class is used in plenty of places besides the command
interpreter (e.g., anything requiring an argc+argv combo, such as when
launching a process), so it needs to be in a lower layer. Now that the
class has no external dependencies, it can be moved down to the Utility
module.
This removes the last (direct) dependency from the Host module to
Interpreter, so I remove the Interpreter module from Host's dependency
list.

Summary:
In one of the 2 places the LC_BUILD_VERSION load command is handled, there
is a bug preventing us from actually handling them (the address where to
read the load command was not updated). This patch factors reading the
deployment target load commands into a helper and adds testing for the 2
code paths calling the helper.
The testing is a little bit complicated because the only times those load
commands matter is when debugging a simulator process. I added a new
decorator to check that a specific SDK is available. The actual testing was
fairly easy once I knew how to run a simulated process.

Summary:
When a MIG routine returns KERN_FAILURE, the demux function will release any OOL resources like ports. In this case, task_port and thread_port will be released twice, potentially resulting in use after free of the ports.
I don't think we can test this in any useful way

Instead of building debugserver when building lldb, I'd rather pass
LLDB_CODESIGN_IDENTITY="" to cmake and use the one already on my system.
However, on one of my machines I only have the CommandLineTools installed, and
so the hardcoded path to the system debugserver does not work for me.
Additionally, we should verify the LLDB framework exists on the machine before
trying to set the path to debugserver. This allows us to warn the user at
configure time that a system debugserver can't be found if they choose not to
build it themselves.
