Serge Pavlov 52525730a1 Clean up use of C allocation functions
If the value returned by `malloc`, `calloc` or `realloc` is not checked
for null pointer, this change replaces them for `safe_malloc`,
`safe_calloc` or `safe_realloc`, which are defined in the namespace `llvm`.
These function report fatal error on out of memory.

In the plain C files, assertion statements are added to ensure that memory
is successfully allocated.

The aim of this change is to get better diagnostics of OOM on Windows.

Fangrui Song 31b97194e6 [libclang] Add `CXSymbolRole role` to CXIdxEntityRefInfo
Summary:
CXIdxEntityRefInfo contains the member `CXIdxEntityRefKind kind;` to
differentiate implicit and direct calls. However, there are more roles
defined in SymbolRole. Among them, `Read/Write` are probably the most
useful ones as they can be used to differentiate Read/Write occurrences
of a symbol for document highlight in a text document.

Jonathan Coe 45ef5036c9 [libclang] Add PrintingPolicy for pretty printing declarations
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.

happens during parsing, the file is preserved and the client will be able to use
it to generate a reproducer for the crash.

Dave Lee 1a532c9e1d [index] Generate class & metaclass manglings for objc
Summary:
ObjC classes have two associated symbols, one for the class and one for the

This change overloads `CodegenNameGenerator::getAllManglings` to produce both
class and metaclass symbols.

While this function is called by `clang_Cursor_getCXXManglings`, it's only
called for CXXRecordDecl and CXXMethodDecl, and so libclang's behavior is
unchanged.

Erik Verbruggen 346066b68c [libclang] Allow to suspend a translation unit.
A suspended translation unit uses significantly less memory but on the
other side does not support any other calls than
clang_reparseTranslationUnit to resume it or
clang_disposeTranslationUnit to dispose it completely.

This helps IDEs to reduce the memory footprint. The data that is freed
by a call to clang_suspendTranslationUnit will be re-generated on the
next (re)parse anyway. Used with a preamble, this allows pretty fast
resumption of the translation unit for further use (compared to disposal
of the translation unit and a parse from scratch).

Manuel Klimek 016c024ca4 Optionally demote fatal errors to non-fatal errors.
This behavior is enabled when the new CXTranslationUnit_KeepGoing
option is passed to clang_parseTranslationUnit{,2}. It is geared
towards use by IDEs and similar consumers of the clang-c API where
fatal errors may arise when parsing incomplete code mid-edit, or
when include paths are not properly configured yet. In such situations
one still wants to get as much information as possible about a TU.
Previously, the semantic analysis would not instantiate templates
or report additional fatal errors after the first fatal error was
encountered.

Erik Verbruggen 8f9d180f09 Show inclusions from a preamble in clang_getInclusions.
When reparsing a translation unit with preamble generation turned on,
no includes are found. This is due to the fact that all SLocs from
AST/PCH files are skipped as they are 'loaded', and inclusions from a
preamble are also 'loaded'. So, in case a file has a preamble, it first
needs to process those loaded inclusions, and then check for any local
inclusions. This latter one is for any includes that are not part of the
preamble, like includes half-way through a file.

This fixes PR24748.

Benjamin Kramer 5c248d89f3 [libclang] Add a flag to create the precompiled preamble on the first parse.
Summary:
The current default is to create the preamble on the first reparse, aka
second parse. This is useful for clients that do not want to block when
opening a file because serializing the preamble takes a bit of time.
However, this makes the reparse much more expensive and that may be on the
critical path as it's the first interaction a user has with the source code.

YouCompleteMe currently optimizes for the first code interaction by parsing
the file twice when loaded. That's just unnecessarily slow and this flag
helps to avoid that.
