Carlo Bertolli e77d6e0e4d [OpenMP] Initial implementation of parse and sema for composite pragma 'distribute parallel for'
http://reviews.llvm.org/D21564

This patch is an initial implementation for #distribute parallel for.
The main differences that affect other pragmas are:

The implementation of 'distribute parallel for' requires blocking of the associated loop, where blocks are "distributed" to different teams and iterations within each block are scheduled to parallel threads within each team. To implement blocking, sema creates two additional worksharing directive fields that are used to pass the team assigned block lower and upper bounds through the outlined function resulting from 'parallel'. In this way, scheduling for 'for' to threads can use those bounds.
As a consequence of blocking, the stride of 'distribute' is not 1 but it is equal to the blocking size. This is returned by the runtime and sema prepares a DistIncrExpr variable to hold that value.
As a consequence of blocking, the global upper bound (EnsureUpperBound) expression of the 'for' is not the original loop upper bound (e.g. in for(i = 0 ; i < N; i++) this is 'N') but it is the team-assigned block upper bound. Sema creates a new expression holding the calculation of the actual upper bound for 'for' as UB = min(UB, PrevUB), where UB is the loop upper bound, and PrevUB is the team-assigned block upper bound.

Richard Smith 03a4aa3d00 Re-commit r273548, reverted in r273589, with a fix to not produce
-Wfor-loop-analysis warnings for a for-loop with a condition variable. In such
a case, the loop condition variable is modified on each iteration of the loop
by definition.

Original commit message:

Rearrange condition handling so that semantic checks on a condition variable
are performed before the other substatements of the construct are parsed,
rather than deferring them until the end. This allows better error recovery
from semantic errors in the condition, improves diagnostic order, and is a
prerequisite for C++17 constexpr if.

Ben Craig 4067e35fae [Analyzer] Don't cache report generation ExplodedNodes
During the core analysis, ExplodedNodes are added to the
ExplodedGraph, and those nodes are cached for deduplication purposes.

After core analysis, reports are generated. Here, trimmed copies of
the ExplodedGraph are made. Since the ExplodedGraph has already been
deduplicated, there is no need to deduplicate again.

This change makes it possible to add ExplodedNodes to an
ExplodedGraph without the overhead of deduplication. "Uncached" nodes
also cannot be iterated over, but none of the report generation code
attempts to iterate over all nodes. This change reduces the analysis
time of a large .C file from 3m43.941s to 3m40.256s (~1.6% speedup).
It should slightly reduce memory consumption. Gains should be roughly
proportional to the number (and path length) of static analysis
warnings.

This patch enables future work that should remove the need for an
InterExplodedGraphMap inverse map. I plan on using the (now unused)
ExplodedNode link to connect new nodes to the original nodes.

Rafael Espindola c9d336e549 Restructure the propagation of -fPIC/-fPIE.
The PIC and PIE levels are not independent. In fact, if PIE is defined
it is always the same as PIC.

This is clear in the driver where ParsePICArgs returns a PIC level and
a IsPIE boolean. Unfortunately that is currently lost and we pass two
redundant levels down the pipeline.

This patch keeps a bool and a PIC level all the way down to codegen.

Sanjay Patel a4d156980e [x86] AVX FP compare builtins should require AVX target feature (PR28112)
This is a fix for PR28112:
https://llvm.org/bugs/show_bug.cgi?id=28112

The FP comparison intrinsics that take an immediate parameter (rather than specifying
a comparison predicate in the function name) were added with AVX; these are macros in
avxintrin.h. This patch makes clang behavior match gcc (error if a program tries to use 
these without -mavx) and matches the Intel documentation, eg:
VCMPPS: m128 _mm_cmp_ps(m128 a, __m128 b, const int imm)

'V' means this is intended to only work with the AVX form of the instruction.

Saleem Abdulrasool 88879e6559 Driver: introduce and use `-isystem-after` for cross-windows
This mirrors the many other -i*after options to insert a new system search
directory at the end of the search path.  This makes it possible to actually
inject a search path after the resource dir.  This option is similar in spirit
to the /imsvc option in the clang-cl driver.  This is needed to properly use the
driver for Windows targets where the clang headers wrap some of the system
headers.

This concept is actually useful on other targets (e.g. Linux) and would be
really easy to support on the core toolchain.

John Brawn 771721cb35 Don't use static variables in LambdaCapture
When static variables are used in inline functions in header files anything that
uses that function ends up with a reference to the variable. Because
RecursiveASTVisitor uses the inline functions in LambdaCapture that use static
variables any AST plugin that uses RecursiveASTVisitor, such as the
PrintFunctionNames example, ends up with a reference to these variables. This is
bad on Windows when building with MSVC with LLVM_EXPORT_SYMBOLS_FOR_PLUGINS=ON
as variables used across a DLL boundary need to be explicitly dllimported in
the DLL using them.

This patch avoids that by adjusting LambdaCapture to be similar to before
r263921, with a capture of either 'this' or a VLA represented by a null Decl
pointer in DeclAndBits with an extra flag added to the bits to distinguish
between the two. This requires the use of an extra bit, and while Decl does
happen to be sufficiently aligned to allow this it's done in a way that means
PointerIntPair doesn't realise it and gives an assertion failure. Therefore I
also adjust Decl slightly to use LLVM_ALIGNAS to allow this.

Alexey Bataev 86e786bd17 [MSVC] Late parsing of in-class defined member functions in template
classes.

MSVC actively uses unqualified lookup in dependent bases, lookup at the
instantiation point (non-dependent names may be resolved on things
declared later) etc. and all this stuff is the main cause of
incompatibility between clang and MSVC.

Clang tries to emulate MSVC behavior but it may fail in many cases.
clang could store lexed tokens for member functions definitions within
ClassTemplateDecl for later parsing during template instantiation.

It will allow resolving many possible issues with lookup in dependent
base classes and removing many already existing MSVC-specific
hacks/workarounds from the clang code.

Adam Nemet 2de463ece3 Add loop pragma for Loop Distribution
Summary:
This is similar to other loop pragmas like 'vectorize'.  Currently it
only has state values: distribute(enable) and distribute(disable).  When
one of these is specified the corresponding loop metadata is generated:

  !{!"llvm.loop.distribute.enable", i1 true/false}

As a result, loop distribution will be attempted on the loop even if
Loop Distribution in not enabled globally.  Analogously, with 'disable'
distribution can be turned off for an individual loop even when the pass
is otherwise enabled.

There are some slight differences compared to the existing loop pragmas.

1. There is no 'assume_safety' variant which makes its handling slightly
different from 'vectorize'/'interleave'.

2. Unlike the existing loop pragmas, it does not have a corresponding
numeric pragma like 'vectorize' -> 'vectorize_width'.  So for the
consistency checks in CheckForIncompatibleAttributes we don't need to
check it against other pragmas.  We just need to check for duplicates of
the same pragma.

Samuel Antao c1ffba5062 [CUDA][OpenMP] Create generic offload toolchains
Summary:
This patch introduces the concept of offloading tool chain and offloading kind. Each tool chain may have associated an offloading kind that marks it as used in a given programming model that requires offloading. 

It also adds the logic to iterate on the tool chains based on the kind. Currently, only CUDA is supported, but in general a programming model (an offloading kind) may have associated multiple tool chains that require supporting offloading.

This patch does not add tests - its goal is to keep the existing functionality.

This patch is the first of a series of three that attempts to make the current support of CUDA more generic and easier to extend to other programming models, namely OpenMP. It tries to capture the suggestions/improvements/concerns on the initial proposal in  http://lists.llvm.org/pipermail/cfe-dev/2016-February/047547.html. It only tackles the more consensual part of the proposal, i.e.does not address the problem of intermediate files bundling yet.

Taking the address of a packed member is dangerous since the reduced

Devin Coughlin 160f19cdda [analyzer] Add checker to verify the correct usage of the MPI API
This commit adds a static analysis checker to verify the correct usage of the MPI API in C
and C++. This version updates the reverted r271981 to fix a memory corruption found by the
ASan bots.

Three path-sensitive checks are included:
- Double nonblocking: Double request usage by nonblocking calls without intermediate wait
- Missing wait: Nonblocking call without matching wait.
- Unmatched wait: Waiting for a request that was never used by a nonblocking call

Examples of how to use the checker can be found at https://github.com/0ax1/MPI-Checker

Faisal Vali 67b04465c0 Fix cv-qualification of '*this' captures and nasty bug PR27507
The bug report by Gonzalo (https://llvm.org/bugs/show_bug.cgi?id=27507 -- which results in clang crashing when generic lambdas that capture 'this' are instantiated in contexts where the Functionscopeinfo stack is not in a reliable state - yet getCurrentThisType expects it to be) - unearthed some additional bugs in regards to maintaining proper cv qualification through 'this' when performing by value captures of '*this'.

This patch attempts to correct those bugs and makes the following changes:

   o) when capturing 'this', we do not need to remember the type of 'this' within the LambdaScopeInfo's Capture - it is never really used for a this capture - so remove it.
   o) teach getCurrentThisType to walk the stack of lambdas (even in scenarios where we run out of LambdaScopeInfo's such as when instantiating call operators) looking for by copy captures of '*this' and resetting the type of 'this' based on the constness of that capturing lambda's call operator.

This patch has been baking in review-hell for > 6 weeks - all the comments so far have been addressed and the bug (that it addresses in passing, and I regret not submitting as a separate patch initially) has been reported twice independently, so is frequent and important for us not to just sit on. I merged the cv qualification-fix and the PR-fix initially in one patch, since they resulted from my initial implementation of star-this and so were related. If someone really feels strongly, I can put in the time to revert this - separate the two out - and recommit.  I won't claim it's immunized against all bugs, but I feel confident enough about the fix to land it for now.

Ben Craig 330c0b6c8c Preallocate ExplodedNode hash table
Rehashing the ExplodedNode table is very expensive. The hashing
itself is expensive, and the general activity of iterating over the
hash table is highly cache unfriendly. Instead, we guess at the
eventual size by using the maximum number of steps allowed. This
generally avoids a rehash. It is possible that we still need to
rehash if the backlog of work that is added to the worklist
significantly exceeds the number of work items that we process. Even
if we do need to rehash in that scenario, this change is still a
win, as we still have fewer rehashes that we would have prior to
this change.

For small work loads, this will increase the memory used. For large
work loads, it will somewhat reduce the memory used. Speed is
significantly increased. A large .C file took 3m53.812s to analyze
prior to this change. Now it takes 3m38.976s, for a ~6% improvement.

George Burgess IV beca4a3338 [Sema] Teach CheckPlaceholderExpr about unaddressable functions.
Given the following C++:

```
void foo();
void foo() __attribute__((enable_if(false, "")));

bool bar() {
  auto P = foo;
  return P == foo;
}
```

We'll currently happily (and correctly) resolve `foo` to the `foo`
overload without `enable_if` when assigning to `P`. However, we'll
complain about an ambiguous overload on the `P == foo` line, because
`Sema::CheckPlaceholderExpr` doesn't recognize that there's only one
`foo` that could possibly work here.

This patch teaches `Sema::CheckPlaceholderExpr` how to properly deal
with such cases.

Grepping for other callers of things like
`Sema::ResolveAndFixSingleFunctionTemplateSpecialization`, it *looks*
like this is the last place that needed to be fixed up. If I'm wrong,
I'll see if there's something we can do that beats what amounts to
whack-a-mole with bugs.

Diagnostics that happen during driver time do not have color output support

Make the driver behave like CC1. There are tests that already check for these

to enable easier and more efficient implementation of the
Standard Library's is_assignable trait.
As of Visual Studio 2015 Update 3, the VC Standard Library
implementation uses the new intrinsic unconditionally.

The implementation is pretty straightforward due to the previously
existing is_nothrow_assignable and is_trivially_assignable.
We handle __is_assignable via the same code as the other two except
that we skip the extra checks for nothrow or triviality.

David Majnemer cd3ebfe293 [MS ABI] Implement __declspec(empty_bases) and __declspec(layout_version)
The layout_version attribute is pretty straightforward: use the layout
rules from version XYZ of MSVC when used like
struct __declspec(layout_version(XYZ)) S {};

The empty_bases attribute is more interesting.  It tries to get the C++
empty base optimization to fire more often by tweaking the MSVC ABI
rules in subtle ways:
1. Disable the leading and trailing zero-sized object flags if a class
   is marked __declspec(empty_bases) and is empty.

   This means that given:
   struct __declspec(empty_bases) A {};
   struct __declspec(empty_bases) B {};
   struct C : A, B {};

   'C' will have size 1 and nvsize 0 despite not being annotated
   __declspec(empty_bases).

2. When laying out virtual or non-virtual bases, disable the injection
   of padding between classes if the most derived class is marked
   __declspec(empty_bases).

   This means that given:
   struct A {};
   struct B {};
   struct __declspec(empty_bases) C : A, B {};

   'C' will have size 1 and nvsize 0.

3. When calculating the offset of a non-virtual base, choose offset zero
   if the most derived class is marked __declspec(empty_bases) and the
   base is empty _and_ has an nvsize of 0.

   Because of the ABI rules, this does not mean that empty bases
   reliably get placed at offset 0!

   For example:
   struct A {};
   struct B {};
   struct __declspec(empty_bases) C : A, B { virtual ~C(); };

   'C' will be pointer sized to account for the vfptr at offset 0.
   'A' and 'B' will _not_ be at offset 0 despite being empty!
   Instead, they will be located right after the vfptr.

   This occurs due to the interaction betweeen non-virtual base layout
   and virtual function pointer injection: injection occurs after the
   nv-bases and shifts them down by the size of a pointer.

Yaxun Liu f7449a179b [OpenCL] Add to_{global|local|private} builtin functions.
OpenCL builtin functions to_{global|local|private} accepts argument of pointer type to arbitrary pointee type, and return a pointer to the same pointee type in different addr space, i.e.

global gentype *to_global(gentype *p);
It is not desirable to declare it as

global void *to_global(void *);
in opencl header file since it misses diagnostics.

This patch implements these builtin functions as Clang builtin functions. In the builtin def file they are defined to have signature void*(void*). When handling call expressions, their declarations are re-written to have correct parameter type and return type corresponding to the call argument.

In codegen call to addr void *to_addr(void*) is generated with addrcasts or bitcasts to facilitate implementation in builtin library.

Summary:
MONITORX/MWAITX instructions provide similar capability to the MONITOR/MWAIT
pair while adding a timer function, such that another termination of the MWAITX
instruction occurs when the timer expires. The presence of the MONITORX and 
MWAITX instructions is indicated by CPUID 8000_0001, ECX, bit 29.

The MONITORX and MWAITX instructions are intercepted by the same bits that
intercept MONITOR and MWAIT. MONITORX instruction establishes a range to be
monitored. MWAITX instruction causes the processor to stop instruction
execution and enter an implementation-dependent optimized state until
occurrence of a class of events.

Opcode of MONITORX instruction is "0F 01 FA". Opcode of MWAITX instruction is
"0F 01 FB". These opcode information is used in adding tests for the
disassembler.

These instructions are enabled for AMD's bdver4 architecture.

would come from changing the type of ASTContext::DeclAttrs from
DenseMap<Decl*,AttrVec*> to DenseMap<Decl*,AttrVec>), and it turns out to be
impractical to avoid the allocation there, because we expose the address of the
attribute vector in ways that are hard to fix.

Adrian McCarthy e4b26fc7a7 Get default -fms-compatibility-version from cl.exe's version
-fms-compatibility-version was defaulting to 18 (VS 2013), which is a pain if your environment is pointing to version 19 (VS 2015) libraries.

If cl.exe can be found, this patch uses its version number as the default instead. It re-uses the existing code to find the Visual Studio binaries folder and WinAPI methods to check its version. You can still explicitly specify a compatibility version on the command line. If you don't have cl.exe, this should be a no-op and you'll get the old default of 18.

This affected the tests, which assumed that if you didn't specific a version, that it would default to 18, but this won't be true for all machines. So a couple test cases had to be eliminated and a couple others had to be tweaked to allow for various outputs.

Bruno Cardoso Lopes b3a0fa4863 [ModuleMap][CrashReproducer] Collect headers from inner frameworks
(1) Collect headers under inner frameworks (frameworks inside other
other frameworks).
(2) Make sure we also collect the right header files inside them.

More info on (2):

Consider a dummy framework module B, with header Frameworks/B/B.h. Now
consider that another framework A, with header Frameworks/A/A.h, has a
layout with a inner framework Frameworks/A/Frameworks/B/B.h, where the
"B/B.h" part is a symlink for Frameworks/B/B.h. Also assume that
Frameworks/A/A.h includes <B/B.h>.

When parsing header Frameworks/A/A.h, framework module lookup is
performed in search for B, and it happens that
"Frameworks/A/Frameworks/B/B.h" path is registered in the module instead
of real "Frameworks/B/B.h". This occurs because
"Frameworks/A/Frameworks/B/B.h" is scanned first by the FileManager,
when looking for inner framework modules under Frameworks/A/Frameworks.
This makes Frameworks/A/Frameworks/B/B.h the default cached named inside
the FileManager for the B.h file UID.

This leads to modules being built without consistent paths to underlying
header files. This is usually not a problem in regular compilation flow,
but it's an issue when running the crash reproducer. The issue is that
clangs collect "Frameworks/A/Frameworks/B/B.h" but not
"Frameworks/B/B.h" into the VFS, leading to err_mmap_umbrella_clash. So
make sure we also collect the original header.

Instead, we consider value-dependent enable_if conditions to always

(specifically, all of the parts that don't expect type dependence to

is enabled on Linux on i386/X86 as well as SystemZ.
This is also the second attempt in commiting this feature. The first attempt

Gabor Horvath 1b3f8db8b6 [ASTMatchers] New matcher forFunction
Summary: Matcher proposed in the review of checker misc-assign-operator (name pending). Its goal is to find the direct enclosing function declaration of a statement and run the inner matcher on it. Two version is attached in this patch (thus it will not compile), to be decided which approach to take. The second one always chooses one single parent while the first one does a depth-first search upwards (thus a height-first search) and returns the first positive match of the inner matcher (thus it always returns zero or one matches, not more). Further questions: is it enough to implement it in-place, or ASTMatchersInternals or maybe ASTMatchFinder should be involved?

Akira Hatanaka 10aced824a [Parser] Clear the TemplateParamScope bit of the current scope's flag
if we are parsing a template specialization.

This commit makes changes to clear the TemplateParamScope bit and set
the TemplateParamParent field of the current scope to null if a template
specialization is being parsed.

Before this commit, Sema::ActOnStartOfLambdaDefinition would check
whether the parent template scope had any decls to determine whether
or not a template specialization was being parsed. This wasn't correct
since it couldn't distinguish between a real template specialization and
a template defintion with an unnamed template parameter (only template
parameters with names are added to the scope's decl list). To fix the
bug, this commit changes the code to check the pointer to the parent
template scope rather than the decl list.

Reid Kleckner f463a8a424 Avoid -Wshadow warnings about constructor parameters named after fields
Usually these parameters are used solely to initialize the field in the
initializer list, and there is no real shadowing confusion.

There is a new warning under -Wshadow called
-Wshadow-field-in-constructor-modified. It attempts to find
modifications of such constructor parameters that probably intended to
modify the field.

It has some false negatives, though, so there is another warning group,
-Wshadow-field-in-constructor, which always warns on this special case.
For users who just want the old behavior and don't care about these fine
grained groups, we have a new warning group called -Wshadow-all that
activates everything.

Peter Collingbourne a8b2f7c0d7 Rework interface for bitset-using features to use a notion of LTO visibility.
Bitsets, and the compiler features they rely on (vtable opt, CFI),
only have visibility within the LTO'd part of the linkage unit. Therefore,
only enable these features for classes with hidden LTO visibility. This
notion is based on object file visibility or (on Windows)
dllimport/dllexport attributes.

We provide the [[clang::lto_visibility_public]] attribute to override the
compiler's LTO visibility inference in cases where the class is defined
in the non-LTO'd part of the linkage unit, or where the ABI supports
calling classes derived from abstract base classes with hidden visibility
in other linkage units (e.g. COM on Windows).

If the cross-DSO CFI mode is enabled, bitset checks are emitted even for
classes with public LTO visibility, as that mode uses a separate mechanism
to cause bitsets to be exported.

This mechanism replaces the whole-program-vtables blacklist, so remove the
-fwhole-program-vtables-blacklist flag.

Because __declspec(uuid()) now implies [[clang::lto_visibility_public]], the
support for the special attr:uuid blacklist entry is removed.

The Decl::isUsed has a value for every decl. In non-module builds it is very
difficult (but possible) to break this invariant but when we walk up the redecl
chain we find the neccessary information.

When deserializing the decls from a module it is much more difficult to update
correctly this invariant. The patch centralizes the information whether a decl
is used in the canonical decl marking the entire entity as being used.

Given that the mappable components are (will be) used in several clauses a new geneneric implementation `OMPMappableExprListClause` is used that extends the existing `OMPVarListClause`.

This patch does not add new tests. The goal is to preserve the existing functionality while storing more info in the clauses.

Nico Weber 47bf505775 driver: Add a `--rsp-quoting` flag to pick response file quoting.
Currently, clang-cl always uses Windows style for unquoting, and clang always
uses POSIX style for unquoting.

With this flag, it's possible to change these defaults.

In general, response file quoting should match the shell the response file is
used in.  On Windows, it's possible to run clang-cl in a bash shell, or clang in
cmd.exe, so a flag for overriding the default behavior is natural there.

On non-Windows, Windows quoting probably never makes sense (except maybe in
Wine), but having clang-cl behave differently based on the host OS seems
strange too.  So require that people who want to use posix-style response
files with clang-cl on non-Windows pass --rsp-quoting=posix.

Eric Liu 4cfb88a936 Added Fixer implementation and fix() interface in clang-format for removing redundant code.
Summary:
After applying replacements, redundant code like extra commas or empty namespaces
might be introduced. Fixer can detect and remove any redundant code introduced by replacements.
The current implementation only handles redundant commas.

Richard Trieu be234c30ad Split interesting warnings off from -Wfloat-conversion
Restructure the implict floating point to integer conversions so that
interesting sub-groups are under different flags.  Breakdown of warnings:

No warning:
Exact conversions from floating point to integer:
int x = 10.0;
int x = 1e10;

-Wliteral-conversion - Floating point literal to integer with rounding:
int x = 5.5;
int x = -3.4;

-Wfloat-conversion - All conversions not covered by the above two:
int x = GetFloat();
int x = 5.5 + 3.5;

-Wfloat-zero-conversion - The expression converted has a non-zero floating
point value that gets converted to a zero integer value, excluded the cases
falling under -Wliteral-conversion.  Subset of -Wfloat-conversion.
int x = 1.0 / 2.0;

-Wfloat-overflow-conversion - The floating point value is outside the range
of the integer type, exluding cases from -Wliteral conversion.  Subset of
-Wfloat-conversion.
char x = 500;
char x = -1000;

-Wfloat-bool-conversion - Any conversion of a floating point type to bool.
Subset of -Wfloat-conversion.
if (GetFloat()) {}
bool x = 5.0;

-Wfloat-bool-constant-conversion - Conversion of a compile time evaluatable
floating point value to bool.  Subset of -Wfloat-bool-conversion.
bool x = 1.0;
bool x = 4.0 / 20.0;

Also add EvaluateAsFloat to Sema, which is similar to EvaluateAsInt, but for
floating point values.

Ahmed Bougacha 1d9de10130 [ARM NEON] Define vfms_f32 on ARM, and all vfms using vfma.
r259537 added vfma/vfms to armv7, but the builtin was only lowered
on the AArch64 side. Instead of supporting it on ARM, get rid of it.

The vfms builtin lowered to:
  %nb = fsub float -0.0, %b
  %r = @llvm.fma.f32(%a, %nb, %c)

Instead, define the operation in terms of vfma, and swap the
multiplicands. It now lowers to:
  %na = fsub float -0.0, %a
  %r = @llvm.fma.f32(%na, %b, %c)

This matches the instruction more closely, and lets current LLVM
generate the "natural" operand ordering:
  fmls.2s v0, v1, v2
instead of the crooked (but equivalent):
  fmls.2s v0, v2, v1
Except for theses changes, assembly is identical.

LLVM accepts both commutations, and the LLVM tests in:
  test/CodeGen/AArch64/arm64-fmadd.ll
  test/CodeGen/AArch64/fp-dp3.ll
  test/CodeGen/AArch64/neon-fma.ll
  test/CodeGen/ARM/fusedMAC.ll
already check either the new one only, or both.

Also verified against the test-suite unittests.

Nemanja Ivanovic 50f29e06a1 Enable support for __float128 in Clang
This patch corresponds to review:
http://reviews.llvm.org/D15120

It adds support for the __float128 keyword, literals and a target feature to
enable it. This support is disabled by default on all targets and any target
that has support for this type is free to add it.

Based on feedback that I've received from target maintainers, this appears to
be the right thing for most targets. I have not heard from the maintainers of
X86 which I believe supports this type. I will subsequently investigate the
impact of enabling this on X86.

Nico Weber fd3e1ad0ce clang-cl: Remove -isystem, add -imsvc.
r260990 exposed -isystem in clang-cl. -isystem adds a directory to the front of
the system include search path. The idea was to use this to point to a hermetic
msvc install, but as it turns out this doesn't work: -isystem then adds the
hermetic headers in front of clang's builtin headers, and clang's headers that
are supposed to wrap msvc headers (say, stdarg.h) aren't picked up at all
anymore.

So revert that, and instead expose -imsvc which works as if the passed
directory was part of %INCLUDE%: The header is treated as a system header, but
it is searched after clang's lib/Header headers.

Fixes half of PRPR26751.

Manman Ren 71224530c1 ObjC kindof: check the context when inserting methods to global pool.
To make kindof lookup work, we need to insert methods with different
context into the global pool, even though they have the same siganture.

Since diagnosis of availability is performed on the best candidate,
which is often the first candidate from the global pool, we prioritize
the methods that are unavaible or deprecated to the head of the list.

Since we now have more methods in the global pool, we need to watch
out for performance impact.

Saleem Abdulrasool f7b3d6c55b Move EABIVersion from CodeGenOptions to TargetOptions
It is possible to argue that the EABIVersion field is similar in spirit to the

Code Generation is arguably not particularly "basic".  This addresses Richard's

will be followed up with an alternate approach to thread the desired information

Alexey Bader 954ba21f85 [OpenCL] Complete image types support.
I. Current implementation of images is not conformant to spec in the following points:
  1. It makes no distinction with respect to access qualifiers and therefore allows to use images with different access type interchangeably. The following code would compile just fine:

        void write_image(write_only image2d_t img);
        kernel void foo(read_only image2d_t img) { write_image(img); } // Accepted code

     which is disallowed according to s6.13.14.

  2. It discards access qualifier on generated code, which leads to generated code for the above example:

        call void @write_image(%opencl.image2d_t* %img);

     In OpenCL2.0 however we can have different calls into write_image with read_only and wite_only images.
     Also generally following compiler steps have no easy way to take different path depending on the image access: linking to the right implementation of image types, performing IR opts and backend codegen differently.

  3. Image types are language keywords and can't be redeclared s6.1.9, which can happen currently as they are just typedef names.
  4. Default access qualifier read_only is to be added if not provided explicitly.

II. This patch corrects the above points as follows:
  1. All images are encapsulated into a separate .def file that is inserted in different points where image handling is required. This avoid a lot of code repetition as all images are handled the same way in the code with no distinction of their exact type.
  2. The Cartesian product of image types and image access qualifiers is added to the builtin types. This simplifies a lot handling of access type mismatch as no operations are allowed by default on distinct Builtin types. Also spec intended access qualifier as special type qualifier that are combined with an image type to form a distinct type (see statement above - images can't be created w/o access qualifiers).
  3. Improves testing of images in Clang.

Richard Smith 351241c83e Replace Sema-level implementation of -fassume-sane-operator-new with a
CodeGen-level implementation. Instead of adding an attribute to clang's
FunctionDecl, add the IR attribute directly. This means a module built with
this flag is now compatible with code built without it and vice versa.

This change also results in the 'noalias' attribute no longer being added to
calls to operator new in the IR; it's now only added to the declaration. It
also fixes a bug where we failed to add the attribute to the 'nothrow' versions
(because we didn't implicitly declare them, there was no good time to inject a
fake attribute).

Instead of searching the global pool multiple times: in
LookupFactoryMethodInGlobalPool, LookupInstanceMethodInGlobalPool,
CollectMultipleMethodsInGlobalPool, and AreMultipleMethodsInGlobalPool,
we now collect the method candidates in CollectMultipleMethodsInGlobalPool
only, and other functions will use the collected method set.

This commit adds parameter "Methods" to AreMultipleMethodsInGlobalPool,
and SelectBestMethod. It also changes the implementation of
CollectMultipleMethodsInGlobalPool to collect the desired kind first, if none is
found, to collect the other kind. This avoids the need to call both
LookupFactoryMethodInGlobalPool and LookupInstanceMethodInGlobalPool.
