Raphael Isemann f974d64b37 [lldb] Deduplicate copy-pasted TypeSystemMap::GetTypeSystemForLanguage
There are two implementations for `TypeSystemMap::GetTypeSystemForLanguage`
which are both identical beside one taking a `Module` and one taking a `Target`
(and then passing that argument to the `TypeSystem::CreateInstance` function).

This merges both implementations into one function with a lambda that wraps the
different calls to `TypeSystem::CreateInstance`.

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.

Pavel Labath 40d774265b [lldb/Utility] Simplify Scalar::PromoteToMaxType
The function had very complicated signature, because it was trying to
avoid making unnecessary copies of the Scalar object. However, this
class is not hot enough to worry about these kinds of optimizations. My
making copies unconditionally, we can simplify the function and all of
its call sites.

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.

shafik 25bbceb047 [LLDB] Fix how ValueObjectChild handles bit-fields stored in a Scalar in UpdateValue()
When bit-field data was stored in a Scalar in ValueObjectChild during UpdateValue()
it was extracting the bit-field value. Later on in lldb_private::DumpDataExtractor(…)
we were again attempting to extract the bit-field. Which would then not obtain the
correct value. This will remove the extra extraction in UpdateValue().
We hit this specific case when values are passed in registers, which we could only
reproduce in an optimized build.

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.

Adrian McCarthy 479f5bfdb0 [LLDB] Improve PDB discovery
When loading a PE/COFF target, the associated PDB file often wasn't
found.  The executable module contains a path for the associated PDB
file, but people often debug from a different directory than the one
their build system uses.  (This is especially common in post-mortem
and cross platform debugging.)

Suppose the COFF executable being debugged is `~/proj/foo.exe`, but
it was built elsewhere and refers to `D:\remote\build\env\foobar.pdb`,
LLDB wouldn't find it.

With this change, if no file exists at the PDB path, LLDB will look
in the executable directory for a PDB file that matches the name of
the one it expected (e.g., `~/proj/foobar.pdb`).  If found, the PDB
is subject to the same matching criteria (GUIDs and age) as would
have been used had it been in the original location.

This same-directory-as-the-binary rule is commonly used by debuggers
on Windows.

 - Add the _python suffix to Python specific functions/targets.
 - Fix a dependency issue that would check the binding instead of

Note that this patch also changes where the bindings are generated,
which might affect downstream projects that check them in.

were adding them in the add_unittest function, but over time we've
accumulated libraries (which don't go through add_unittest) building on

Making this a part of the library interface enables them to be managed

is just pure sugar that should be ignored. If we don't ignore it (as we do now),
LLDB will fail to read values from record fields that have a
SubstTemplateTypeParm type.

Only way to produce such a type in LLDB is to either use the `import-std-module`
setting to get a template into the expression parser or just create your own
template directly in the expression parser which is what we do in the test.

Fangrui Song a6db64ef4a [ELF] Allow sections after a non-SHF_ALLOC section to be covered by PT_LOAD
GNU ld allows sections after a non-SHF_ALLOC section to be covered by PT_LOAD
(PR37607) and assigns addresses to non-SHF_ALLOC output sections (similar to
SHF_ALLOC NOBITS sections. The location counter is not advanced).

This patch tries to fix PR37607 (remove a special case in
`Writer<ELFT>::createPhdrs`). To make the created PT_LOAD meaningful, we cannot
reset dot to 0 for a middle non-SHF_ALLOC output section. This results in
removal of two special cases in LinkerScript::assignOffsets. Non-SHF_ALLOC
non-orphan sections can have non-zero addresses like in GNU ld.

The zero address rule for non-SHF_ALLOC sections is weakened to apply to orphan
only. This results in a special case in createSection and findOrphanPos, respectively.

`getCompilerVersion` assumes that `clang --version` prints out a string like `version [0-9\.]+`.
If clang is built from trunk, the version line might look like `clang version trunk (123abc)`.

Since there isn't any way of knowing by the commit id alone whether one commit is newer or older than another git commit (or clang version), assume that clang with a version id like this is very close to trunk. For example, any tests with `@skipIf(compiler="clang", compiler_version=['<', '8'])` should be run.

Jordan Rupprecht fcb0d8163a [lldb/test] Use realpath consistently for test root file paths.
LLDB tests assume that tests are in the test tree (the `LLDB_TEST_SRC` env variable, configured by `dotest.py`).
If this assertion doesn't hold, tests fail in strange ways. An early place this goes wrong is in `compute_mydir` which does a simple length-based substring to get the relative path. Later, we use that path to chdir to. If the test file and test tree don't agree in realpath-ness (and therefore length), this will be a cryptic error of chdir-ing to a directory that does not exist.

The actual discrepency is that the places we look for `use_lldb_suite.py` don't use a realpath, but `dotest.py` does (see initialization of `configuration.testdirs`).

It doesn't particularly matter whether we use realpath or abspath to canonicalize things, but many places end up with implicit dependencies on the canonicalized pwd being a realpath, so make them realpath consistently. Also, in the `compute_mydir` method mentioned, raise an error if the path types don't agree.

In these two cases, use of `os.path.realpath` is problematic:

- The name of the compiler is significant [1] . For testing purposes, we might
  provide a compiler called "clang" which is actually a symlink to some build
  script (which does some flag processing before invoking the real clang). The
  destination the symlink may not be called "clang", but we still want it to be
  treated as such.
- When using a build system that puts build artifacts in an arbitrary build
  location, and later creates a symlink for it (e.g. creates a
  "<lldb root>/lldbsuite/test/dotest.py" symlinks that points to
  "/build/artifact/<hash>/dotest.py"), looking at the realpath will not match
  the "test" convention required here.

Jason Molenda abf546dd4f debguserver's type sniffer to only treat .app things that end in .app
On an iOS device, if debugserver is left to figure out how to launch
the binary provided, it looks at the filename to see if it contains
".app" and asks FrontBoard to launch it.  However, if this is actually
a command line app with the characters ".app" in the name, it would
end up trying to launch that via the FrontBoard calls even though it
needed to be launched via posix_spawn.  For instance, a command line
program called com.application.tester.

Jim suggested this patch where we only send binaries that end in ".app"
to FrontBoard.

Often debugsever is invoked with a --launch command line argument to
specify the launch method, and none of this code is hit in that
instance.

Jordan Rupprecht be198e03eb [lldb][test] Move registers-target-xml-reading target to the correct test location.
This test was added in D74217 (and the `.categories` file later added in ccf1c30cde) around the same time I moved the test tree from `lldb/packages/Python/lldbsuite/test` to `lldb/test/API` (D71151). Since this got lost in the move, it isn't running. (I introduced an intentional syntax error, and `ninja check-lldb` passes).

I moved it to the correct location, and now it runs and passes -- locally, at least -- as `ninja check-lldb-api-tools-lldb-server-registers-target-xml-reading`.

Tatyana Krasnukha da0bba5c9a [lldb/Breakpoint] Rename StoppointLocation to StoppointSite and drop its relationship with BreakpointLocation
Both of BreakpointLocation and BreakpointSite were inherited from StoppointLocation. However, the only thing
they shared was hit counting logic. The patch encapsulates those logic into StoppointHitCounter, renames
StoppointLocation to StoppointSite, and stops BreakpointLocation's inheriting from it.

Tatyana Krasnukha ebaa8b1c60 [lldb] Don't use hardware index to determine whether a breakpoint site is hardware
Most process plugins (if not all) don't set hardware index for breakpoints. They even
are not able to determine this index.

This patch makes StoppointLocation::IsHardware pure virtual and lets BreakpointSite
override it using more accurate BreakpointSite::Type.

It also adds assertions to be sure that a breakpoint site is hardware when this is required.

Jonas Devlieghere 4add853647 [lldb] Improve platform handling in CreateTargetInternal
Currently, `target create` has no --platform option. However,
TargetList::CreateTargetInternal which is called under the hood, will
return an error when either no platform or multiple matching platforms
are found, saying that a platform should be specified with --platform.

This patch adds the platform option, but that doesn't solve either of
these errors.

 - If more than one platform matches, specifying the platform isn't
   going to fix that. The current code will only look at the
   architecture instead. I've updated the error message to ask the user
   to specify an architecture.

 - If no architecture is found, specifying a new one via platform isn't
   going to change that either because we already try to find one that
   matches the given architecture.
