Mandeep Singh Grang c205d8cc8d [clang] Change std::sort to llvm::sort in response to r327219
r327219 added wrappers to std::sort which randomly shuffle the container before
sorting.  This will help in uncovering non-determinism caused due to undefined
sorting order of objects having the same key.

To make use of that infrastructure we need to invoke llvm::sort instead of
std::sort.

Yuka Takahashi 41789e46a6 [Bash-autocompletion] Pass all flags in shell command-line to Clang
Previously, we passed "#" to --autocomplete to indicate to enable cc1
flags. For example, when -cc1 or -Xclang was passed to bash, bash
executed `clang --autocomplete=#-<flag they want to complete>`.

However, this was not a good implementation because it depends -Xclang
and -cc1 parsing to shell. So I changed this to pass all flags shell
has, so that Clang can handle them internally.

I had to change many testcases because API spec changed quite a lot.

Joel E. Denny 4925445958 [Attr] Fix parameter indexing for several attributes
The patch fixes a number of bugs related to parameter indexing in
attributes:

* Parameter indices in some attributes (argument_with_type_tag,
  pointer_with_type_tag, nonnull, ownership_takes, ownership_holds,
  and ownership_returns) are specified in source as one-origin
  including any C++ implicit this parameter, were stored as
  zero-origin excluding any this parameter, and were erroneously
  printing (-ast-print) and confusingly dumping (-ast-dump) as the
  stored values.

* For alloc_size, the C++ implicit this parameter was not subtracted
  correctly in Sema, leading to assert failures or to silent failures
  of __builtin_object_size to compute a value.

* For argument_with_type_tag, pointer_with_type_tag, and
  ownership_returns, the C++ implicit this parameter was not added
  back to parameter indices in some diagnostics.

This patch fixes the above bugs and aims to prevent similar bugs in
the future by introducing careful mechanisms for handling parameter
indices in attributes.  ParamIdx stores a parameter index and is
designed to hide the stored encoding while providing accessors that
require each use (such as printing) to make explicit the encoding that
is needed.  Attribute declarations declare parameter index arguments
as [Variadic]ParamIdxArgument, which are exposed as ParamIdx[*].  This
patch rewrites all attribute arguments that are processed by
checkFunctionOrMethodParameterIndex in SemaDeclAttr.cpp to be declared
as [Variadic]ParamIdxArgument.  The only exception is xray_log_args's
argument, which is encoded as a count not an index.

Alexey Bataev cbecfdfefe [OpenMP] Fix trailing space when printing pragmas, by Joel. E. Denny
Summary:
-ast-print prints omp pragmas with a trailing space.  While this
behavior is likely of little concern to most users, surely it's
unintentional, and it's annoying for some source-level work I'm
pursuing.  This patch focuses on omp pragmas, but it also fixes
init_seg and loop hint pragmas because they share implementation.

The testing strategy here is to add usually just one '{{$}}' per
relevant -ast-print test file.  This seems to achieve good code
coverage.  However, this strategy is probably easy to forget as the
tests evolve.  That's probably fine as this fix is far from critical.
The main goal of the testing is to aid the initial review.

This patch also adds a fixme for "#pragma unroll", which prints as
"#pragma unroll (enable)", which is invalid syntax.

Richard Smith 33bddbd64b Make attribute instantiation instantiate all attributes, not just the first of
each kind.

Attribute instantiation would previously default to instantiating each kind of
attribute only once. This was overridden by a flag whose intended purpose was
to permit attributes from a prior declaration to be inherited onto a new
declaration even if that new declaration had its own copy of the attribute.
This is the wrong behavior: when instantiating attributes from a template, we
should always instantiate all the attributes that were written on that
template.

This patch renames the flag in the Attr class (and TableGen sources) to more
clearly identify what it's actually for, and removes the usage of the flag from
template instantiation. I also removed the flag from AlignedAttr, which was
only added to work around the incorrect suppression of duplicate attribute
instantiation.

This patch adds support to the attribute tablegen for specifying a [[]] attribute is allowed in C mode. This patch also adds the annotate attribute to the list of double square bracket attributes we support in C mode.

Eventually, I anticipate that this logic will be reversed (you have to opt out of allowing an attribute in C rather than opting in), but I want to see how the design plays out as more attributes are considered.

This patch changes the name of TargetArch to TargetSpecific
(since it checks much more than just Arch), makes "Arch" optional, adds
support for ObjectFormat, better documents the TargetSpecific type, and
changes IFunc over to a TargetSpecificAttr.

Aaron Ballman adf66b6174 Determine the attribute subject for diagnostics based on declarative information in DeclNodes.td. This greatly reduces the number of enumerated values used for more complex diagnostics; these are now only required when the "attribute only applies to" diagnostic needs to be generated manually as part of semantic processing.
This also clarifies some terminology used by the diagnostic (methods -> Objective-C methods, fields -> non-static data members, etc).

Many of the tests needed to be updated in multiple places for the diagnostic wording tweaks. The first instance of the diagnostic for that attribute is fully specified and subsequent instances cut off the complete list (to make it easier if additional subjects are added in the future for the attribute).

Changes all existing attributes that currently use GNU<"attr"> and CXX11<"clang", "attr> spellings to instead use the Clang<"attr"> spelling.

No additional tests are necessary because the existing tests already use both spellings for the attributes converted to the new spelling. No functional changes are expected.

There was one instance where an unnecessary 'stringstream' was being used,
so that has been removed as well to unblock the stringref replacing string fix.

Yuka Takahashi 66256906c3 [Bash-autocompletion] Show HelpText with possible flags
Summary:
`clang --autocomplete=-std` will show
```
-std:   Language standard to compile for
-std=   Language standard to compile for
-stdlib=        C++ standard library to use
```
after this change.

However, showing HelpText with completion in bash seems super tricky, so
this feature will be used in other shells (fish, zsh...).

Summary:
File path wasn't autocompleted after `-fmodule-cache-path=[tab]`, so
fixed this bug by checking if $flags contains only a newline or not.

Yuka Takahashi 33cf63b7f2 [Bash-autocompletion] Auto complete cc1 options if -cc1 is specified
Summary:
We don't want to autocomplete flags whose Flags class has `NoDriverOption` when argv[1] is not `-cc1`.

Another idea for this implementation is to make --autocomplete a cc1
option and handle it in clang Frontend, by porting --autocomplete
handler from Driver to Frontend, so that we can handle Driver options
and CC1 options in unified manner.

Alex Lorenz 24952fbc6f Add #pragma clang attribute support to the external_source_symbol attribute
Prior to this commit the external_source_symbol attribute wasn't supported by
#pragma clang attribute for the following two reasons:

- The Named attribute subject hasn't been supported by TableGen.
- There was no way to specify a subject match rule for #pragma clang attribute
 that could operate on a set of attribute subjects (e.g. the ones that derive
 from NamedDecl).

This commit fixes the two issues and thus adds external_source_symbol support to
#pragma clang attribute.

The original commit message is displayed below:

The new '#pragma clang attribute' directive can be used to apply attributes to
multiple declarations. An attribute must satisfy the following conditions to
be supported by the pragma:
- It must have a subject list that's defined in the TableGen file.
- It must be documented.
- It must not be late parsed.
- It must have a GNU/C++11 spelling.

Erich Keane a32910da1a Correct class-template deprecation behavior-REDUX
Correct class-template deprecation behavior

Based on the comment in the test, and my reading of the standard, a deprecated warning should be issued in the following case:
template<typename T> [[deprecated]] class Foo{}; Foo<int> f;

This was not the case, because the ClassTemplateSpecializationDecl creation did not also copy the deprecated attribute.

Note: I did NOT audit the complete set of attributes to see WHICH ones should be copied, so instead I simply copy ONLY the deprecated attribute.
