Bruno Cardoso Lopes f56ef90e26 [CMAKE][c-index-test] Honor CMAKE_OSX_SYSROOT to compute include dir for libxml2
On MacOS, if CMAKE_OSX_SYSROOT is used and the user has command line tools
installed, we currently get the include path for libxml2 as
/usr/include/libxml2, instead of ${CMAKE_OSX_SYSROOT}/usr/include/libxml2.

Make it consistent on MacOS by prefixing ${CMAKE_OSX_SYSROOT} when
possible.

Zachary Turner 08426e1f9f Refactor ExecuteAndWait to take StringRefs.
This simplifies some code which had StringRefs to begin with, and
makes other code more complicated which had const char* to begin
with.

In the end, I think this makes for a more idiomatic and platform
agnostic API.  Not all platforms launch process with null terminated
c-string arrays for the environment pointer and argv, but the api
was designed that way because it allowed easy pass-through for
posix-based platforms.  There's a little additional overhead now
since on posix based platforms we'll be takign StringRefs which
were constructed from null terminated strings and then copying
them to null terminate them again, but from a readability and
usability standpoint of the API user, I think this API signature
is strictly better.

Shoaib Meenai db5781a78f [cmake] Support LLD for CLANG_ORDER_FILE
LLD also supports order files using the `--symbol-ordering-file` option.
As the name would suggest, the order file format is slightly different
from gold; gold's order files specify section names, whereas LLD's
specify symbol names. Assuming you have an order file in the correct
format though, we should support using it with LLD.

Switch the check to actually use LLVM's linker detection rather than
just checking for the presence of the gold executable, since we might
have a gold executable present but be using LLD (or bfd for that matter)
as our linker.

Jonas Devlieghere b48447a1d6 [diagtool] Add diagtool to install target.
Although not very well known, diagtool is an incredibly convenient
utility for dealing with diagnostics.
Particularly useful are the "tree" and "show-enabled" commands:

 - The former prints the hierarchy of diagnostic (warning) flags and
   which of them are enabled by default.
 - The latter can be used to replace an invocation to clang and will
   print which diagnostics are disabled, warnings or errors.
   For instance: `diagtool show-enabled -Wall -Werror /tmp/test.c` will
   print that -Wunused-variable (warn_unused_variable) will be treated as
   an error.

This patch adds them to the install target so it gets shipped with the
LLVM release. It also adds a very basic man page and mentions this
change in the release notes.

libclang exposes the type of 'int (Foo);' (a global variable of type int

Nirav Dave 6c0665e221 [MC] Change AsmParser to leverage Assembler during evaluation
Teach AsmParser to check with Assembler for when evaluating constant
expressions.  This improves the handing of preprocessor expressions
that must be resolved at parse time. This idiom can be found as
assembling-time assertion checks in source-level assemblers. Note that
this relies on the MCStreamer to keep sufficient tabs on Section /
Fragment information which the MCAsmStreamer does not. As a result the
textual output may fail where the equivalent object generation would
pass. This can most easily be resolved by folding the MCAsmStreamer
and MCObjectStreamer together which is planned for in a separate
patch.

Currently, this feature is only enabled for assembly input, keeping IR
compilation consistent between assembly and object generation.

Richard Smith b5f8171a1b PR37189 Fix incorrect end source location and spelling for a split '>>' token.
When a '>>' token is split into two '>' tokens (in C++11 onwards), or (as an
extension) when we do the same for other tokens starting with a '>', we can't
just use a location pointing to the first '>' as the location of the split
token, because that would result in our miscomputing the length and spelling
for the token. As a consequence, for example, a refactoring replacing 'A<X>'
with something else would sometimes replace one character too many, and
similarly diagnostics highlighting a template-id source range would highlight
one character too many.

Fix this by creating an expansion range covering the first character of the
'>>' token, whose spelling is '>'. For this to work, we generalize the
expansion range of a macro FileID to be either a token range (the common case)
or a character range (used in this new case).

Erik Verbruggen c068e9094a [libclang] Only mark CXCursors for explicit attributes with a type
All attributes have a source range associated with it. However, implicit
attributes are added by the compiler, and not added because the user
wrote something in the input. So no token type should be set to
CXCursor_*Attr.

The problem was visible when a class gets marked by e.g.
MSInheritanceAttr, which has the full CXXRecordDecl's range as its
own range. The effect of marking that range as CXCursor_UnexposedAttr
was that all cursors for the record decl, including all child decls,
would become CXCursor_UnexposedAttr.

Instead, pass the original SourceLocation which preserves all information, and
update consumers to match current behavior.

This allows us to fix two bugs in clangd that need the spelling location.

I presume WorkingDir is somehow changed to /usr/lib or /usr/include and
clang_getFileName() returns a path relative to WorkingDir.

clang_File_tryGetRealPathName() returns "/usr/include/c++/7.3.0/string"
which is more useful for the indexer in this case.

Alex Lorenz 045c514fb4 Recommit r329442: Generate Libclang invocation reproducers using a new
-cc1gen-reproducer driver option

The recommit fixes:
- An MSAN failure (CCPrintOptions wasn't initialized in the Driver)
- Ensures that the strings in the libclang invocation files are escaped

Original message:

This commit is a follow up to the previous work that recorded Libclang invocations
into temporary files: r319702.

It adds a new -cc1 mode to clang: -cc1gen-reproducer. The goal of this mode is to generate
Clang reproducer files for Libclang tool invocation. The JSON format in the invocation
files is not really intended to be stable, so Libclang and Clang should be of the same version
when generating reproducers.
The new mode emits the information about the temporary files and Libclang-specific information
to stdout using JSON.

Alex Lorenz 1e720916fa Generate Libclang invocation reproducers using a new -cc1gen-reproducer
driver option

This commit is a follow up to the previous work that recorded Libclang invocations
into temporary files: r319702.

It adds a new -cc1 mode to clang: -cc1gen-reproducer. The goal of this mode is to generate
Clang reproducer files for Libclang tool invocation. The JSON format in the invocation
files is not really intended to be stable, so Libclang and Clang should be of the same version
when generating reproducers.
The new mode emits the information about the temporary files and Libclang-specific information
to stdout using JSON.

Alexander Kornienko d10d790044 Allow the creation of human-friendly ASTDumper to arbitrary output stream
Summary:
`ASTPrinter` allows setting the ouput to any O-Stream, but that printer creates source-code-like syntax (and is also marked with a `FIXME`). The nice, colourful, mostly human-readable `ASTDumper` only works on the standard output, which is not feasible in case a user wants to see the AST of a file through a code navigation/comprehension tool.

This small addition of an overload solves generating a nice colourful AST block for the users of a tool I'm working on, [[ http://github.com/Ericsson/CodeCompass | CodeCompass ]], as opposed to having to duplicate the behaviour of definitions that only exist in the anonymous namespace of implementation TUs related to this module.

This meant the logic to guess Objective-C from the contents

code to work with.

With this fix, we now correctly read in the contents of the
file if possible with -dump-config.

I had to update the lit config for test/Format/ because
the default config ignores .h files.

Summary:
Introduce clang_getCursorPrettyPrinted() for pretty printing
declarations. Expose also PrintingPolicy, so the user gets more
fine-grained control of the entities being printed.

The already existing clang_getCursorDisplayName() is pretty limited -
for example, it does not handle return types, parameter names or default
arguments for function declarations. Addressing these issues in
clang_getCursorDisplayName() would mean to duplicate existing code
(e.g. clang::DeclPrinter), so rather expose new API to access the
existing functionality.

Sam McCall bb2cf63b32 [CodeComplete] Add an option to omit results from the preamble.
Summary:
Enumerating the contents of a namespace or global scope will omit any
decls that aren't already loaded, instead of deserializing them from the
PCH.

This allows a fast hybrid code completion where symbols from headers are
provided by an external index. (Sema already exposes the information
needed to do a reasonabl job of filtering them).
Clangd plans to implement this hybrid.

This option is just a hint - callers still need to postfilter results if
they want to *avoid* completing decls outside the main file.

Summary:
DC may sometimes be NULL and getContainerInfo(DC, Container) will dereference a null pointer.

Default template arguments (the following example and many test files in https://github.com/nlohmann/json)
may cause null pointer dereference.

```c++
template <typename>
struct actor;

template <template <typename> class Actor = actor>
struct terminal;
```

In tools/libclang/CXIndexDataConsumer.cpp#L203

    handleReference(ND, Loc, Cursor,
                    dyn_cast_or_null<NamedDecl>(ASTNode.Parent),
                    ASTNode.ContainerDC, ASTNode.OrigE, Kind);

`dyn_cast_or_null<NamedDecl>(ASTNode.Parent)` is somehow a null pointer and in tools/libclang/CXIndexDataConsumer.cpp:935

  ContainerInfo Container;
  getContainerInfo(DC, Container);

The null DC is casted `ContInfo.cursor = getCursor(cast<Decl>(DC));` and SIGSEGV.

Sam McCall e83ae11ccc [Index] Reduce size of SymbolInfo struct.
Summary:
This is currently 16 bytes, the patch reduces it to 4.
(Building with clang on linux x84, I guess others are similar)

The only subfield that might need a bigger type is SymbolPropertySet,
I've moved it to the end of the struct so if it grows, SymbolInfo will
only be 8 bytes.

With a full index of namespace-scope symbols from the LLVM project (200k)
loaded into clangd, this saves ~2MB of RAM.
