Aaron Ballman 12b9f6535b Factored some function-like type reasoning out of SemaDeclAttr and onto Decl itself. This allows for more declarative subjects in attribute tablegen where the attribute appertains to something function-like, but not strictly a FunctionDecl.

Aaron Ballman 36a5350e51 Distinguish between attributes explicitly written at the request of the user, and attributes implicitly generated to assist in bookkeeping by the compiler. This is done so by table generating a CreateImplicit method for each attribute.
Additionally, remove the optional nature of the spelling list index when creating attributes. This is supported by table generating a Spelling enumeration when the spellings for an attribute are distinct enough to warrant it.

Kostya Serebryany 317e2c499d replace LeakSanitizerIsTurnedOffForTheCurrentProcess with __lsan_is_turned_off, but this time hide it under __has_feature(address_sanitizer); also include <sanitizer/lsan_interface.h>

Aaron Ballman 09e98ffa5b When determining the attribute's parsed kind, pay attention to the syntax used. This fixes bugs where an attribute has differing GNU and Declspec spellings, but they are treated as the same. Eg) __declspec(aligned) when it should be __attribute__((aligned)), and __attribute__((align)) when it should be __declspec(align).

Aaron Ballman 0fa06d879a __has_attribute now understands target-specific attributes. So when you ask whether an ARM target has the "interrupt" attribute, it will return true for ARM and MSP430 targets, and false for others.

Aaron Ballman ab7691c4ce Removing the notion of TargetAttributesSema and replacing it with one where the parsed attributes are responsible for knowing their target-specific nature, instead of letting Sema figure it out. This is necessary so that __has_attribute can eventually determine whether a parsed attribute applies to the given target or not.

Alp Toker 96af9886ef Revert "Disable LeakSanitizer in TableGen binaries, see PR18325"
To declare or define reserved identifers is undefined behaviour in standard
C++. This needs to be addressed in compiler-rt before it can be used in LLVM.

See the list discussion for details.

This reverts commit r198858.

Aaron Ballman 15b27b97b7 Removing a bit of custom parsing functionality used by the thread safety analysis APIs. Now using tablegen to determine whether an attribute's arguments should be parsed in an unevaluated context instead of relying on a separate, hard-coded list of attributes.

DeLesley Hutchins c4a82438a7 Update RecursiveASTVisitor so that it visits attributes. This is currently

Aaron Ballman 3e424b5070 Teach the diagnostics engine about the Attr type to make reporting on semantic attributes easier (and not require hard-coded strings). This requires a getSpelling() function on the Attr class, which is table-driven. Updates a handful of cases where a hard-coded string was being used to test the functionality out. Updating associated test cases for the improved quoting.

Hao Liu 4b850c5e0d revert r196152.
This is a duplicate implementation.
E.g. this patch defines:
     float64_t vabd_f64(float64_t a, float64_t b)
But there is already a similar intrinsic "vabdd_f64" with the same types.
Also, this intrinsic will be conflicted to the vector type intrinsic as following(Which is implemented by me and will be committed to trunk):
     float64x1_t vabd_f64(float64x1_t a, float64x1_t b).
Two functions shouldn't have a same name in arm_neon.h.
According to ARM ACLE document, such vabd_f64 with float64_t is not existing.
So I revert this commit.

Aaron Ballman 74eeeae3d3 Laying the basic groundwork for table generating the diagnostics for attribute subjects. This makes some modifications to the way subjects are listed in Attr.td, and updates the attr emitter to handle the new constructs.
I have disabled some attribute subject lines on purpose in Attr.td;
this part is a WIP with the goal being to restore those subjects
incrementally. By commenting them out, it leaves the original behavior
the same as before for those attributes and so those are not
functionality changes.

I've manually checked that the handlers for all these attributes can in fact
cope with an identifier as the argument. This is still somewhat terrible; we
should move more fully towards picking the parsing rules based on the
attribute, and make the Parse -> Sema interface more type-safe.

The individual group and subgroups tables are now two large tables. The option table stores an index into these two tables instead of pointers. This reduces the size of the options tabe since it doesn't need to store pointers. It also reduces the number of relocations needed.

Jim Grosbach d10f1c04aa ARM: Improve codegen for vget_low_* and vget_high_ intrinsics.
These intrinsics use the __builtin_shuffle() function to extract the
low and high half, respectively, of a 128-bit NEON vector. Currently,
they're defined to use bitcasts to simplify the emitter, so we get code
like:
uint16x4_t vget_low_u32(uint16x8_t __a) {
  return (uint32x2_t) __builtin_shufflevector((int64x2_t) __a,
                                              (int64x2_t) __a,
                                              0);
}

While this works, it results in those bitcasts going all the way through
to the IR, resulting in code like:
  %1 = bitcast <8 x i16> %in to <2 x i64>
  %2 = shufflevector <2 x i64> %1, <2 x i64> undef, <1 x i32>
  %zeroinitializer
  %3 = bitcast <1 x i64> %2 to <4 x i16>

We can instead easily perform the operation directly on the input vector
like:

uint16x4_t vget_low_u16(uint16x8_t __a) {
  return __builtin_shufflevector(__a, __a, 0, 1, 2, 3);
}

Not only is that much easier to read on its own, it also results in
cleaner IR like:

  %1 = shufflevector <8 x i16> %in, <8 x i16> undef,
                     <4 x i32> <i32 0, i32 1, i32 2, i32 3>

This is both easier to read and easier for the back end to reason
about effectively since the operation is obfuscating the source with
bitcasts.

Douglas Gregor d2472d4cdb Use attribute argument information to determine when to parse attribute arguments as expressions.
This change partly addresses a heinous problem we have with the
parsing of attribute arguments that are a lone identifier. Previously,
we would end up parsing the 'align' attribute of this as an expression
"(Align)":

 template<unsigned Size, unsigned Align>
 class my_aligned_storage
 {
   __attribute__((align((Align)))) char storage[Size];
 };

while this would parse as a "parameter name" 'Align':

 template<unsigned Size, unsigned Align>
 class my_aligned_storage
 {
   __attribute__((align(Align))) char storage[Size];
 };

The code that handles the alignment attribute would completely ignore
the parameter name, so the while the first of these would do what's
expected, the second would silently be equivalent to

 template<unsigned Size, unsigned Align>
 class my_aligned_storage
 {
   __attribute__((align)) char storage[Size];
 };

i.e., use the maximal alignment rather than the specified alignment.

Address this by sniffing the "Args" provided in the TableGen
description of attributes. If the first argument is "obviously"
something that should be treated as an expression (rather than an
identifier to be matched later), parse it as an expression.

Introduce a spelling index to Attr class, which is an index into the attribute spelling list of an attribute defined in Attr.td. 
This index will determine the actual spelling used by an attribute, as it incorporates both the syntax and naming of the attribute.
When constructing an attribute AST node, the spelling index is computed based on attribute kind, scope (if it's a C++11 attribute), and
name, then passed to Attr that will use the index to print itself.

Each option has a set of prefixes. When matching an argument such as

a lower_bound search for "funroll-loops" is done against the option table by
option name. From there each option prefix + option name combination is tested
against the argument.

This allows us to support Microsoft style options where both / and - are valid
prefixes. It also simplifies the cases we already have where options come in
both - and -- forms. Almost every option for gnu-ld happens to have this form.

Dmitri Gribenko 7acbf00f96 Comment AST: TableGen'ize all command lists in CommentCommandTraits.cpp.
Now we have a list of all commands.  This is a good thing in itself, but it
also enables us to easily implement typo correction for command names.

With this change we have objects that contain information about each command,
so it makes sense to resolve command name just once during lexing (currently we
store command names as strings and do a linear search every time some property
value is needed).  Thus comment token and AST nodes were changed to contain a
command ID -- index into a tables of builtin and registered commands.  Unknown
commands are registered during parsing and thus are also uniformly assigned an
ID.  Using an ID instead of a StringRef is also a nice memory optimization
since ID is a small integer that fits into a common bitfield in Comment class.

This change implies that to get any information about a command (even a command
name) we need a CommandTraits object to resolve the command ID to CommandInfo*.
Currently a fresh temporary CommandTraits object is created whenever it is
needed since it does not have any state.  But with this change it has state --
new commands can be registered, so a CommandTraits object was added to
ASTContext.

Also, in libclang CXComment has to be expanded to include a CXTranslationUnit
so that all functions working on comment AST nodes can get a CommandTraits
object.  This breaks binary compatibility of CXComment APIs.

Now clang_FullComment_getAsXML(CXTranslationUnit TU, CXComment CXC) doesn't
need TU parameter anymore, so it was removed.  This is a source-incompatible
change for this C API.

This patch introduces some magic in tablegen to create a "Pedantic" diagnostic
group which automagically includes all warnings that are extensions.  This
allows a user to suppress specific warnings traditionally under -pedantic used
an ordinary warning flag.  This also allows users to use #pragma to silence
specific -pedantic warnings, or promote them to errors, within blocks of text
(just like any other warning).

-Wpedantic is NOT an alias for -pedantic.  Instead, it provides another way
to (a) activate -pedantic warnings and (b) disable them.  Where they differ
is that -pedantic changes the behavior of the preprocessor slightly, whereas
-Wpedantic does not (it just turns on the warnings).

The magic in the tablegen diagnostic emitter has to do with computing the minimal
set of diagnostic groups and diagnostics that should go into -Wpedantic, as those
diagnostics that already members of groups that themselves are (transitively) members
of -Wpedantic do not need to be included in the Pedantic group directly.  I went
back and forth on whether or not to magically generate this group, and the invariant
was that we always wanted extension warnings to be included in -Wpedantic "some how",
but the bookkeeping would be very onerous to manage by hand.

-no-pedantic (and --no-pedantic) is included for completeness, and matches many of the
same kind of flags the compiler already supports.  It does what it says: cancels out
-pedantic.  One discrepancy is that if one specifies --no-pedantic and -Weverything or
-Wpedantic the pedantic warnings are still enabled (essentially the -W flags win).  We
can debate the correct behavior here.

Along the way, this patch nukes some code in TextDiagnosticPrinter.cpp and CXStoredDiagnostic.cpp
that determine whether to include the "-pedantic" flag in the warning output.  This is
no longer needed, as all extensions now have a -W flag.

This patch also significantly reduces the number of warnings not under flags from 229
to 158 (all extension warnings).  That's a 31% reduction.

Dmitri Gribenko ec92531c29 Implement AST classes for comments, a real parser for Doxygen comments and a
very simple semantic analysis that just builds the AST; minor changes for lexer
to pick up source locations I didn't think about before.

Comments AST is modelled along the ideas of HTML AST: block and inline content.

* Block content is a paragraph or a command that has a paragraph as an argument
  or verbatim command.
* Inline content is placed within some block.  Inline content includes plain
  text, inline commands and HTML as tag soup.

Alexis Hunt 7b28cdb3da Improve the specification of spellings in Attr.td.
Note that this is mostly a structural patch that handles the change from the old
spelling style to the new one. One consequence of this is that all AT_foo_bar
enum values have changed to not be based off of the first spelling, but rather
off of the class name, so they are now AT_FooBar and the like (a straw poll on
IRC showed support for this). Apologies for code churn.

Most attributes have GNU spellings as a temporary solution until everything else
is sorted out (such as a Keyword spelling, which I intend to add if someone else
doesn't beat me to it). This is definitely a WIP.

I've also killed BaseCheckAttr since it was unused, and I had to go through
every attribute anyway.

Rafael Espindola 7f90b7d4c2 Fix our handling of visibility in explicit template instantiations.
* Don't copy the visibility attribute during instantiations. We have to be able
  to distinguish

 struct HIDDEN foo {};
 template<class T>
 DEFAULT void bar() {}
 template DEFAULT void bar<foo>();

from

 struct HIDDEN foo {};
 template<class T>
 DEFAULT void bar() {}
 template void bar<foo>();

* If an instantiation has an attribute, it takes precedence over an attribute
  in the template.

* With instantiation attributes handled with the above logic, we can now
  select the minimum visibility when looking at template arguments.

Michael Han 4a04517329 Refactor Clang sema attribute handling.
This submission improves Clang sema handling by using Clang tablegen
to generate common boilerplate code. As a start, it implements AttributeList
enumerator generation and case statements for AttributeList::getKind.

A new field "SemaHandler" is introduced in Attr.td and by default set to 1
as most of attributes in Attr.td have semantic checking in Sema. For a small
number of attributes that don't appear in Sema, the value is set to 0.

Also there are a small number of attributes that only appear in Sema but not
in Attr.td. Currently these attributes are still hardcoded in Sema AttributeList.

Bob Wilson bd646de67f Relax type checking for a few Neon intrinsics. <rdar://problem/10538555>
Not long ago, I tightened up the type checking for pointer arguments of
Neon intrinsics to match the specifications provided by ARM.  One consequence
was that it became impossible to access the unaligned versions of a few
Neon load/store operations.  Since there are just a few of these intrinsics
where it makes a difference, I think it's better to relax the type checking
than to either introduce new non-standard unaligned intrinsics or to disallow
intrinsics for the unaligned operations.

Bob Wilson 89d14247ff Fix Neon builtin pointer argument checking for "sret" builtins.
The code for checking Neon builtin pointer argument types was assuming that
there would only be one pointer argument.  But, for vld2-4 builtins, the first
argument is a special sret pointer where the result will be stored.  So,
instead of scanning all the arguments to find a pointer, have TableGen figure
out the index of the pointer argument that needs checking.  That's better than
scanning all the arguments regardless.  <rdar://problem/10448804>

Bob Wilson e4d7723b87 Check pointer types for arguments of Neon load/store macros. rdar://9958031
The Neon load/store intrinsics need to be implemented as macros to avoid
hiding alignment attributes on the pointer arguments, and the macros can
only evaluate those pointer arguments once (in case they have side effects),
so it has been hard to get the right type checking for those pointers.
I tried various alternatives in the arm_neon.h header, but it's much more
straightforward to just check directly in Sema.
