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. 
llvm-svn: 198897
 2014-01-09 22:57:44 +00:00
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.

Chandler Carruth 5553d0d4ca Sort all the #include lines with LLVM's utils/sort_includes.py which

DeLesley Hutchins c4a82438a7 Update RecursiveASTVisitor so that it visits attributes. This is currently 
important for thread safety attributes, which contain expressions that were
not being visited, and were thus invisible to various tools.  There are now
Visit*Attr methods that can be overridden for every attribute.

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.

Aaron Ballman 64e6986e39 Allow target-specific attributes to share a spelling between different attributes via the ParseKind field. Attributes will be given a common parsed attribute identifier (the AttributeList::AT_* enum), but retain distinct Attr subclasses. 
This new functionality is used to implement the ARM and MSP430 interrupt attribute.

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.

There seem to be quite a few references to the old macro __ARM_NEON__ on the

yet), but the canonical name does not have the trailing underscores so we

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.

When running a make-based command, SATestBuild tries to append a -jN flag

Craig Topper d80c17e060 Merge diagnostic group tables to reduce data size and relocation entries. 
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.

My build shows this reducing DiagnosticsIDs.o and the clang binary by ~20.5K. It also removes ~400 relocation entries from DiagnosticIDs.o.

Tim Northover 2fe823a6c3 AArch64: initial NEON support 
Patch by Ana Pazos

- Completed implementation of instruction formats:
AdvSIMD three same
AdvSIMD modified immediate
AdvSIMD scalar pairwise

- Completed implementation of instruction classes
(some of the instructions in these classes
belong to yet unfinished instruction formats):
Vector Arithmetic
Vector Immediate
Vector Pairwise Arithmetic

- Initial implementation of instruction formats:
AdvSIMD scalar two-reg misc
AdvSIMD scalar three same

- Intial implementation of instruction class:
Scalar Arithmetic

- Initial clang changes to support arm v8 intrinsics.
Note: no clang changes for scalar intrinsics function name mangling yet.

- Comprehensive test cases for added instructions
To verify auto codegen, encoding, decoding, diagnosis, intrinsics.

Jordan Rose c7b992edcf [analyzer] SATestBuild: Don't require reference results to have logs. 
The Logs directory isn't used for testing, so it's filtered out ahead of
time. However, there's then no reason to include it in version control at
all. Don't error if it's not present.

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.
