Jonas Devlieghere 57e0ef131b [lldb] Make it a fatal error when %lldb cannot be substituted
Refuse to run the shell tests when %lldb cannot be substituted. This
prevents the test from silently running again the `lldb` in your PATH.

I noticed because when this happens, %lldb-init gets substituted with
lldb-init, which does not exists.

Jonas Devlieghere 73af341beb [lldb] Capture and load home directory from the reproducer.
When replaying the reproducer, lldb should source the .lldbinit file
that was captured by the reproducer and not the one in the current home
directory. This requires that we store the home directory as part of the
reproducer. By returning the virtual home directory during replay, we
ensure the correct virtual path gets constructed which the VFS can then
find and remap to the correct file in the reproducer root.

This patch adds a new HomeDirectoryProvider, similar to the existing
WorkingDirectoryProvider. As the home directory is not part of the VFS,
it is stored in LLDB's FileSystem instance.

ObjectFile::BaseAddress() is designed to be overridden by all classes and is for mach-o, ELF and COFF plug-ins. They find the header base adddress and return that as a section offset address.

David Blaikie f7a49d2aa6 [WIP][DebugInfo] Lazily parse debug_loclist offsets
Parsing DWARFv5 debug_loclist offsets when a CU is parsed is weighing
down memory usage of symbolizers that don't need to parse this data at
all. There's not much benefit to caching these anyway - since they are
O(1) lookup and reading once you know where the offset list starts (and
can do bounds checking with the offset list size too).

In general, I think it might be time to start paying down some of the
technical debt of loc/loclist/range/rnglist parsing to try to unify it a
bit more.

eg:

* Currently DWARFUnit has: RangeSection, RangeSectionBase, LocSection,
  LocSectionBase, LocTable, RngListTable, LoclistTableHeader (be nice if
  these were all wrapped up in two variables - one for loclists, one for
  rnglists)

* rnglists and loclists are handled differently (see:
  LoclistTableHeader, but no RnglistTableHeader)

* maybe all these types could be less stateful - lazily parse what they
  need to, even reparsing rather than caching because it doesn't seem
  too expensive, for instance. (though admittedly so long as it's
  constantcost/overead per compilatiton that's probably adequate)

* Maybe implementing and using a DWARFDataExtractor that can be
  sub-ranged (so we could slice it up to just the single contribution) -
  though maybe that's not so useful because loc/ranges need to refer to
  it by absolute, not contribution-relative mechanisms

Pavel Labath 67cdb899c6 [lldb/Utility] Simplify and generalize Scalar class
The class contains an enum listing all host integer types as well as
some non-host types. This setup is a remnant of a time when this class
was actually implemented in terms of host integer types. Now that we are
using llvm::APInt, they are mostly useless and mean that each function
needs to enumerate all of these cases even though it treats most of them
identically.

I only leave e_sint and e_uint to denote the integer signedness, but I
want to remove that in a follow-up as well.

Removing these cases simplifies most of these functions, with the only
exception being PromoteToMaxType, which can no longer rely on a simple
enum comparison to determine what needs to be promoted.

This also makes the class ready to work with arbitrary integer sizes, so
it does not need to be modified when someone needs to add a larger
integer size.

case, clang will hit an assertion when adding a member to an incomplete

It turns out we already had code to handle a similar situation arising
in the -gmodules scenario. This extends the code to handle
-flimit-debug-info as well, and reorganizes bits of other code handling

Raphael Isemann c2f9454a16 [lldb] Add SBModule::GarbageCollectAllocatedModules and clear modules after each test run
Right now the only places in the SB API where lldb:: ModuleSP instances are
destroyed are in SBDebugger::MemoryPressureDetected (where it's just attempted
but not guaranteed) and in SBDebugger::DeleteTarget (which will be removed in
D83933). Tests that directly create an lldb::ModuleSP and never create a target
therefore currently leak lldb::Module instances. This triggers the sanity checks
in lldbtest that make sure that the global module list is empty after a test.

This patch adds SBModule::GarbageCollectAllocatedModules as an explicit way to
clean orphaned lldb::ModuleSP instances. Also we now start calling this method
at the end of each test run and move the sanity check behind that call to make
this work. This way even tests that don't create targets can pass the sanity
check.

This fixes TestUnicodeSymbols.py when D83865 is applied (which makes that the
sanity checks actually fail the test).

Raphael Isemann c57ea1b48f [lldb] Get lldb-server platform's --socket-file working again
`lldb-server platform --socket-file /any/path` currently always fails to create
the socket file.  This stopped working after D67424 which changed the
input variables of `writeFileAtomically` slightly. We're expected to
pass in a temporary path template (`/tmp/foo-%%%%%`) and the final
path we want to write. Instead we currently pass in the never set
`temp_file_path` as the temporary path (which will make this function always
fail) and pass in the temp_file_spec's path as the final path (which is actually
the template path such as `/tmp/foo-%%%%%`) instead of the actual path
we want to write (e.g. `/tmp/foo`).

correct type. This patch changes that to search for an entry of the

Shu Anzai de9e85026f [lldb] Display autosuggestion part in gray if there is one possible suggestion
This is relanding D81001. The patch originally failed as on newer editline
versions it seems CC_REFRESH will move the cursor to the start of the line via
\r and then back to the original position. On older editline versions like
the one used by default on macOS, CC_REFRESH doesn't move the cursor at all.
As the patch changed the way we handle tab completion (previously we did
REDISPLAY but now we're doing CC_REFRESH), this caused a few completion tests
to receive this unexpected cursor movement in the output stream.
This patch updates those tests to also accept output that contains the specific
cursor movement commands (\r and then \x1b[XC). lldbpexpect.py received an
utility method for generating the cursor movement escape sequence.

Original summary:

I implemented autosuggestion if there is one possible suggestion.
I set the keybinds for every character. When a character is typed, Editline::TypedCharacter is called.
Then, autosuggestion part is displayed in gray, and you can actually input by typing C-k.
Editline::Autosuggest is a function for finding completion, and it is like Editline::TabCommand now, but I will add more features to it.

Testing does not work well in my environment, so I can't confirm that it goes well, sorry. I am dealing with it now.

Raphael Isemann bbe3c479a6 [lldb] Fix a crash when tab-completion an empty line in a function with only one local variable
When LLDB sees only one possible completion for an input, it will add a trailing
space to the completion to signal that to the user. If the current argument is
quoted, that also means LLDB needs to add the trailing quote to finish the
current argument first.

In case the user is in a function with only one local variable and is currently
editing an empty line in the multiline expression editor, then we are in the
unique situation where we can have a unique completion for an empty input line.
(In a normal LLDB session this would never occur as empty input would just list
all the possible commands).

In this special situation our check if the current argument needs to receive a
trailing quote will crash LLDB as there is no current argument and the
completion code just unconditionally tries to access the current argument. This
just adds the missing check if we even have a current argument before we check
if we need to add a terminating quote character.

Raphael Isemann dd0fdf8030 [lldb] Add support for checking children in expect_expr
expect_expr currently can't verify the children of the result SBValue.

This patch adds the ability to check them. The idea is to have a CheckValue
class where one can specify what attributes of a SBValue should be checked.
Beside the properties we already check for (summary, type, etc.) this also
has a list of children which is again just a list of CheckValue object (which
can also have children of their own).

The main motivation is to make checking the children no longer based
on error-prone substring checks that allow tests to pass just because
for example the error message contains the expected substrings by accident.

I also expect that we can just have a variant of `expect_expr` for LLDB's
expression paths (aka 'frame var') feature.
