Nico Weber 0abcafd8a4 Make clang/test/Index/pch-from-libclang.c pass in more places
- fixes the test on macOS with LLVM_ENABLE_PIC=OFF
- together with D57343, gets the test to pass on Windows
- makes it run everywhere (it seems to just pass on Linux)

The main change is to pull out the resource directory computation into a
function shared by all 3 places that do it. In CIndexer.cpp, this now works no
matter if libclang is in lib/ or bin/ or statically linked to a binary in bin/.

Alex Lorenz 977ffd7b8f [libclang] CoroutineBody/Coreturn statements are UnexposedStmts and not Exprs
This change ensures that the libclang CXCursor represents the CoroutineBody
and the Coreturn statement using the appropriate CXCursor_UnexposedStmt kind
instead of CXCursor_UnexposedExpr. The problem with CXCursor_UnexposedExpr is
that the consumer functions assumed that CoroutineBody/Coreturn statements
were valid expressions and performed an invalid downcast to Expr causing
assertion failures or other crashes.

Haojian Wu ef87c26796 [AST] Unify the code paths of traversing lambda expressions.
Summary:
This supposes to be a non-functional change. We have two code paths when
traversing lambda expressions:

1) traverse the function proto typeloc when parameters and return type
are explicit;
2) otherwise fallback to traverse parameter decls and return type loc
individually;

This patch unifies the code path to always traverse parameters and
return type, rather than relying on traversing the full type-loc.

Change in r337953 violated the contract for `CXTranslationUnit_KeepGoing`:

> Do not stop processing when fatal errors are encountered.

Use different approach to fix long processing times with multiple inclusion
cycles. Instead of stopping preprocessing for fatal errors, do this after
reaching the max allowed include depth and only for the files that were
processed already. It is likely but not guaranteed those files cause a cycle.

Ilya Biryukov ebf0a6d75d [CodeComplete] Do not complete self-initializations
Summary:
Removes references to initialized variable from the following completions:

    int x = ^;

Handles only the trivial cases where the variable name is completed
immediately at the start of initializer or assignment, more complicated
cases aren't covered, e.g. these completions still contain 'x':

    // More complicated expressions.
    int x = foo(^);
    int x = 10 + ^;
    // Other kinds of initialization.
    int x{^};
    int x(^);
    // Constructor initializers.
    struct Foo {
      Foo() : x(^) {}
      int x;
    };

We should address those in the future, but they are outside of the scope of
this initial change.

Michael Kruse dc5ce72afa Append new attributes to the end of an AttributeList.
Recommit of r335084 after revert in r335516.

... instead of prepending it at the beginning (the original behavior
since implemented in r122535 2010-12-23). This builds up an
AttributeList in the the order in which the attributes appear in the
source.

The reverse order caused nodes for attributes in the AST (e.g. LoopHint)
to be in the reverse order, and therefore printed in the wrong order in
-ast-dump. Some TODO comments mention this. The order was explicitly
reversed for enable_if attribute overload resolution and name mangling,
which is not necessary anymore with this patch.

The change unfortunately has some secondary effect, especially on
diagnostic output. In the simplest cases, the CHECK lines or expected
diagnostic were changed to the the new output. If the kind of
error/warning changed, the attributes' order was changed instead.

This unfortunately causes some 'previous occurrence here' hints to be
textually after the main marker. This typically happens when attributes
are merged, but are incompatible to each other. Interchanging the role
of the the main and note SourceLocation will also cause the case where
two different declaration's attributes (in contrast to multiple
attributes of the same declaration) are merged to be reverse. There is

declaration's attribute list, sometimes new attributes are added to a

Michael Kruse ea31f0e4b8 Append new attributes to the end of an AttributeList.
... instead of prepending it at the beginning (the original behavior
since implemented in r122535 2010-12-23). This builds up an
AttributeList in the the order in which the attributes appear in the
source.

The reverse order caused nodes for attributes in the AST (e.g. LoopHint)
to be in the reverse, and therefore printed in the wrong order by
-ast-dump. Some TODO comments mention this. The order was explicitly
reversed for enable_if attribute overload resolution and name mangling,
which is not necessary anymore with this patch.

The change unfortunately has some secondary effects, especially for
diagnostic output. In the simplest cases, the CHECK lines or expected
diagnostic were changed to the the new output. If the kind of
error/warning changed, the attribute's order was changed instead.

It also causes some 'previous occurrence here' hints to be textually
after the main marker. This typically happens when attributes are
merged, but are incompatible. Interchanging the role of the the main
and note SourceLocation will also cause the case where two different
declaration's attributes (in contrast to multiple attributes of the
same declaration) are merged to be reversed. There is no easy fix
because sometimes previous attributes are merged into a new
declaration's attribute list, sometimes new attributes are added to a
previous declaration's attribute list. Since 'previous occurrence here'
pointing to locations after the main marker is not rare, I left the
markers as-is; it is only relevant when the attributes are declared in
the same declaration anyway, which often is on the same line.

Sven van Haastregt 4700faa28e [OpenCL] Add separate read_only and write_only pipe IR types
SPIR-V encodes the read_only and write_only access qualifiers of pipes,
so separate LLVM IR types are required to target SPIR-V.  Other backends
may also find this useful.

These new types are `opencl.pipe_ro_t` and `opencl.pipe_wo_t`, which
replace `opencl.pipe_t`.

This replaces __get_pipe_num_packets(...) and __get_pipe_max_packets(...)
which took a read_only pipe with separate versions for read_only and
write_only pipes, namely:

 * __get_pipe_num_packets_ro(...)
 * __get_pipe_num_packets_wo(...)
 * __get_pipe_max_packets_ro(...)
 * __get_pipe_max_packets_wo(...)

These separate versions exist to avoid needing a bitcast to one of the
two qualified pipe types.

Ilya Biryukov b3510c4254 [CodeComplete] Fix completion at the end of keywords
Summary:
Make completion behave consistently no matter if it is run at the
start, in the middle or at the end of an identifier that happens to
be a keyword or a macro name. Since completion is often ran on
incomplete identifiers, they may turn into keywords by accident.

For example, we should produce same results for all of these
completion points:

    // ^ is completion point.
    ^class
    cla^ss
    class^

Previously clang produced different results for the last case (as if
the completion point was after a space: `class ^`).

This change also updates some offsets in tests that (unintentionally?)
relied on the old behavior.

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,

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.

Ilya Biryukov 659cffeec4 [Sema] Add implicit members even for invalid CXXRecordDecls
Summary:
It should be safe, since other code paths are already generating
implicit members even in invalid CXXRecordDecls (e.g. lookup).

If we don't generate implicit members on CXXRecordDecl's completion,
they will be generated by next lookup of constructors. This causes a
crash when the following conditions are met:
  - a CXXRecordDecl is invalid,
  - it is provided via ExternalASTSource (e.g. from PCH),
  - it has inherited constructors (they create ShadowDecls),
  - lookup of its constructors was not run before ASTWriter serialized
    it.

This may require the ShadowDecls created for inherited constructors to
be removed from the class, but that's no longer possible since class is
provided by ExternalASTSource.

See provided lit test for an example.

This is the right behavior for the existing callsite in ASTDumper, but I think

While here:
 - remove an unused test file accidentally added in r322371.

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.

Erich Keane bb322555af For Linux/gnu compatibility, preinclude <stdc-predef.h> if the file is available
As reported in llvm bugzilla 32377.
Here’s a patch to add preinclude of stdc-predef.h.

The gcc documentation says “On GNU/Linux, <stdc-predef.h> is pre-included.” See https://gcc.gnu.org/gcc-4.8/porting_to.html;

The preinclude is inhibited with –ffreestanding.

Basically I fixed the failing test cases by adding –ffreestanding which inhibits this behavior.

I fixed all the failing tests, including some in extra/test, there's a separate patch for that which is linked here

Note: this is a recommit after a test failure took down the original (r318669)

Alex Lorenz 690f0e2f4e [libclang] Record code-completion invocations to a temporary file when
requested by client

This is a follow up to r319702 which records parsing invocations.

These files are not emitted by default, and the client has to specify the
invocation emission path first.
