Anastasia Stulova 1202de3ec8 [OpenCL] Disable C99 standard lib functions
The library functions defined in the C99 standard headers
are not available (OpenCL v1.2 s6.9.f). 

This change stops treating OpenCL builtin functions as standard C lib
functions to eliminate warning messages about printf format string.

Anastasia Stulova b607e0f238 [OpenCL] Eliminate warning when declaring OpenCL builtin functions.
OpenCL builtin functions are usually declared in header files.
Currently clang emits warning for OpenCL builtin functions
which have the same name as standard C library functions.

This commit eliminates such warnings by not adding the C standard
includes following the restriction from OpenCL v1.2 s6.9.f.

George Burgess IV a2f29fa694 [Sema] Make extended vectors of `bool` an error.
In OpenCL, `bool` vectors are a reserved type, and are therefore
illegal.

Outside of OpenCL, if we try to make an extended vector of N `bool`s,
Clang will lower it to an `[N x i1]`. LLVM has no ABI for bitvectors, so
lots of operations on such vectors are thoroughly broken. As a result,
this patch makes them illegal in everything else, as well. :)

Fix arc patch fuzz error.
Summary:
Support for the pipe built-in functions for OpenCL 2.0.
The pipe builtin functions may have infinite kinds of element types, one approach
would be to just generate calls that would always use generic types such as void*.

Sameer Sahasrabuddhe a75db66eee Restores r228382, which was reverted in r228406.
The original commit failed to handle "shift assign" (<<=), which
broke the test mentioned in r228406. This is now fixed and the
test added to the lit tests under SemaOpenCL.

*** Original commit message from r228382 ***

OpenCL: handle shift operator with vector operands

Introduce a number of checks:
1. If LHS is a scalar, then RHS cannot be a vector.
2. Operands must be of integer type.
3. If both are vectors, then the number of elements must match.

Relax the requirement for "usual arithmetic conversions":
When LHS is a vector, a scalar RHS can simply be expanded into a
vector; OpenCL does not require that its rank be lower than the LHS.
For example, the following code is not an error even if the implicit
type of the constant literal is "int".

  char2 foo(char2 v) { return v << 1; }

Consolidate existing tests under CodeGenOpenCL, and add more tests
under SemaOpenCL.

Tom Stellard 96d5dc77fa Revert "OpenCL: handle shift operator with vector operands"
This reverts commit r228382.

This breaks the following case:  Reported by Jeroen Ketema:
http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20150202/122961.html

typedef __attribute__((ext_vector_type(3))) char char3;

void foo() {
 char3 v = {1,1,1};
 char3 w = {1,2,3};

 w <<= v;
}

If I compile with:

 clang -x cl file.c

Then an error is produced:

file.c:10:5: error: expression is not assignable
 w <<= v;
 ~ ^
1 error generated.

Sameer Sahasrabuddhe e8d2aaf320 OpenCL: handle ternary operator when the condition is a vector
When the condition is a vector, OpenCL specifies additional
requirements on the operand types, and also the operations
required to determine the result type of the operator. This is a
combination of OpenCL v1.1 s6.3.i and s6.11.6, and the semantics
remain unchanged in later versions of OpenCL.

Fraser Cormack cc6e894587 Fix OpenCL 1.2 double as an optional core feature behaviour
In OpenCL 1.2, using double no longer requires using the pragma cl_khr_fp64,
instead a kernel is allowed to use double, but must first have queried
clGetDeviceInfo's CL_DEVICE_DOUBLE_FP_CONFIG.

Page 197, section 6.1.1 of the OpenCL 1.2 specification has a footnote 23
describing this behaviour.

I've also added test cases such that the pragma must be used if targeting
OpenCL 1.0 or 1.1, but is ignored in 1.2 and 2.0.

Benjamin Kramer 1adc8c3391 Print detailed vector type information on diagnostics.
We never aka vector types because our attributed syntax for it is less
comprehensible than the typedefs. This leaves the user in the dark when
the typedef isn't named that well.

Example:
  v2s v; v4f w;
  w = v;

The naming in this cases isn't even that bad, but the error we give is
useless without looking up the actual typedefs.
t.c:6:5: error: assigning to 'v4f' from incompatible type 'v2s'

Now:
t.c:6:5: error: assigning to 'v4f' (vector of 4 'float' values) from
    incompatible type 'v2s' (vector of 2 'int' values)

We do this for all diagnostics that print a vector type.

Tanya Lattner 4fdce3faa8 Extend the support for cl-std to include 1.2.
Add error checking for the static qualifier which is now allowed in certain situations for OpenCL 1.2. Use the CL version to turn on this feature.
Added test case for 1.2 static storage class feature.

Tanya Lattner 49b3841398 The comparison of two vectors should return a signed result. hasIntegerRepresentation() used to always return false for vectors, but since it was changed, it also
changed the return type of a compare of two unsigned vectors to be unsigned. This patch removes the check for hasIntegerRepresentation since its not needed and returns the appropriate signed type.
I added a new test case and updated exisiting test cases that assumed an unsigned result.

Tobias Grosser 766bcc27dc In OpenCL, conversions between different vector types are disallowed
OpenCL 6.2.1 says: "Implicit conversions between built-in vector data types are
disallowed."  OpenCL 6.2.2 says: "Explicit casts between vector types are not
legal."  For example:

uint4 u = (uint4)(1);
int4 i = u; // invalid implicit conversion
int4 e = (int4)u; // invalid explicit conversion

Tobias Grosser 0a3a22fe66 In the OpenCL mode, the AltiVec mode must be off and checks must be strict
OpenCL is different from AltiVec in the way it supports vector literals.  OpenCL
is strict with regards to semantic checks.  For example, implicit conversions
and explicit casts between vectors of different types are disallowed.
