Alex Langford 7dfb095b88 [lldb-vscode] correctly handle multiple sourceMap entries
Summary:
`lldb-vscode` concatenates a string of sourceMap entries
specified in the config, but fails to put a space between
each entry, which causes the settings command to fail.
This patch adds a space between each mapping.

Lawrence D'Anna 2fce1137c7 Convert FileSystem::Open() to return Expected<FileUP>
Summary:
This patch converts FileSystem::Open from this prototype:

Status
Open(File &File, const FileSpec &file_spec, ...);

to this one:

llvm::Expected<std::unique_ptr<File>>
Open(const FileSpec &file_spec, ...);

This is beneficial on its own, as llvm::Expected is a more modern
and recommended error type than Status.  It is also a necessary step
towards https://reviews.llvm.org/D67891, and further developments
for lldb_private::File.

Pavel Labath 8865ebb509 SystemInitializer: Use Targets.def to selectively initialize ABI plugins
This avoids having to define additional macros in the cmake file, and
and also makes the logic in the cpp files more compact. It is also
easily extendible to other plugin types (instruction emulation?) that
should only be initialized if the corresponding llvm target is built.

Thanks to Ilya Birukov for pointing me to this file.

tests but no passing tests. This will not affect the situation where
there are failures or unexpected passes, because those report a non-zero

Jonas Devlieghere 7fa72881d4 [Dwarf] Make dw_tag_t a typedef for llvm::dwarf::Tag instead of uint16_t.
Currently dw_tag_t is a typedef for uint16_t. This patch changes makes
dw_tag_t a typedef for llvm::dwarf::Tag. This enables us to use the full
power of the DWARF utilities in LLVM without having to do the cast every
time. With this approach, we only have to do the cast when reading the
ULEB value.

Raphael Isemann 6f9f8f411f [lldb][modern-type-lookup] Add two basic tests for modern-type-lookup
The story so far: LLDB's modern type lookup mode has no (as in, 0%) test
coverage. It was supposed to be tested by hardcoding the default to 'true' and then running
the normal LLDB tests, but to my knowledge no one is doing that. As a around 130 tests
seem to fail with this mode enabled, we also can't just enable it globally for now.

As we touch the surrounding code all the time and also want to refactor parts of it, we
should be a bit more ambitious with our testing efforts.

So this patch adds two basic tests that enable this mode and do some
basic expression parsing which should hopefully be basic enough to not
break anywhere but still lets us know if this mode works at all (i.e. setting up the
ExternalASTMerger in LLDB, using its basic import functionality to move declarations
around and do some lookups).

Pavel Labath d0b44dbefd Have ABI plugins vend llvm MCRegisterInfo data
Summary:
I was recently surprised to learn that there is a total of 2 (two) users
of the register info definitions contained in the ABI plugins. Yet, the
defitions themselves span nearly 10kLOC.
The two users are:
 - dwarf expression pretty printer
 - the mechanism for augmenting the register info definitions obtained
   over gdb-remote protocol (AugmentRegisterInfoViaABI)

Both of these uses need the DWARF an EH register numbers, which is
information that is already available in LLVM. This patch makes it
possible to do so.

It adds a GetMCRegisterInfo method to the ABI class, which every class
is expected to implement. Normally, it should be sufficient to obtain
the definitions from the appropriate llvm::Target object (for which I
provide a utility function), but the subclasses are free to construct it
in any way they deem fit.

We should be able to always get the MCRegisterInfo object from llvm,
with one important exception: if the relevant llvm target was disabled
at compile time. To handle this, I add a mechanism to disable the
compilation of ABI plugins based on the value of LLVM_TARGETS_TO_BUILD
cmake setting. This ensures all our existing are able to create their
MCRegisterInfo objects.

The new MCRegisterInfo api is not used yet, but the intention is to make
use of it in follow-up patches.

was well-intended, it (presumably) unintentionally removed the logic to

using the just-built debugserver.

This patch partially recovers the old behavior: when
LLDB_USE_SYSTEM_DEBUGSERVER is set we don't build debugserver and just
copy over the system one.
