* Fix usage of right shift operator in fold expressionsRichard Smith2017-10-311-3/+4
| | | | | | | | | The right shift operator was not seen as a valid operator in a fold expression, which is PR32563. Patch by Nicolas Lesser ("Blitz Rakete")! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@317032 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix PR25627: constant expressions being odr-used in template arguments.Faisal Vali2017-05-201-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch ensures that clang processes the expression-nodes that are generated when disambiguating between types and expressions within template arguments as constant-expressions by installing the ConstantEvaluated ExpressionEvaluationContext just before attempting the disambiguation - and then making sure that Context carries through into ParseConstantExpression (by refactoring it out into a function that does not create its own EvaluationContext: ParseConstantExpressionInExprEvalContext) Note, prior to this patch, trunk would correctly disambiguate and identify the expression as an expression - and while it would annotate the token with the expression - it would fail to complete the odr-use processing (specifically, failing to trigger Sema::UpdateMarkingForLValueToRValue as is done for all Constant Expressions, which would remove it from being considered odr-used). By installing the ConstantExpression Evaluation Context prior to disambiguation, and making sure it carries though, we ensure correct processing of the expression-node. For e.g: template<int> struct X { }; void f() { const int N = 10; X<N> x; // should be OK. [] { return X<N>{}; }; // Should be OK - no capture - but clang errors! } See a related bug: https://bugs.llvm.org//show_bug.cgi?id=25627 In summary (and reiteration), the fix is as follows: - Remove the EnteredConstantEvaluatedContext action from ParseTemplateArgumentList (relying on ParseTemplateArgument getting it right) - Add the EnteredConstantEvaluatedContext action just prior to undergoing the disambiguating parse, and if the parse succeeds for an expression, carry the context though into a refactored version of ParseConstantExpression that does not create its own ExpressionEvaluationContext. See https://reviews.llvm.org/D31588 for additional context regarding some of the more fragile and complicated approaches attempted, and Richard's feedback that eventually shaped the simpler and more robust rendition that is being committed.

* Fix the location of "missing ';'" suggestions after annotation tokens.Richard Smith2017-05-181-2/+2
| | | | | | | | | | | We were incorrectly setting PrevTokLocation to the first token in the annotation token instead of the last when consuming it. To fix this without adding a complex switch to the hot path through ConsumeToken, we now have a ConsumeAnnotationToken function for consuming annotation tokens in addition to the other Consume*Token special case functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@303372 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | template-id. The heuristic that we use here is: * the left-hand side must be a simple identifier or a class member access * the right-hand side must be '<' followed by either a '>' or by a type-id that cannot be an expression (in particular, not followed by '(' or '{') * there is a '>' token matching the '<' token The second condition guarantees the expression would otherwise be ill-formed. If we're confident that the user intended the name before the '<' to be interpreted as a template, diagnose the fact that we didn't interpret it that way, rather than diagnosing that the template arguments are not valid expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@302615 91177308-0d34-0410-b5e6-96231b3b80d8

* Store decls in prototypes on the declarator instead of in the ASTReid Kleckner2016-12-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This saves two pointers from FunctionDecl that were being used for some rare and questionable C-only functionality. The DeclsInPrototypeScope ArrayRef was added in r151712 in order to parse this kind of C code: enum e {x, y}; int f(enum {y, x} n) { return x; // should return 1, not 0 } The challenge is that we parse 'int f(enum {y, x} n)' it its own function prototype scope that gets popped before we build the FunctionDecl for 'f'. The original change was doing two questionable things: 1. Saving all tag decls introduced in prototype scope on a TU-global Sema variable. This is problematic when you have cases like this, where 'x' and 'y' shouldn't be visible in 'f': void f(void (*fp)(enum { x, y } e)) { /* no x */ } This patch fixes that, so now 'f' can't see 'x', which is consistent with GCC. 2. Storing the decls in FunctionDecl in ActOnFunctionDeclarator so that they could be used in ActOnStartOfFunctionDef. This is just an inefficient way to move information around. The AST lives forever, but the list of non-parameter decls in prototype scope is short lived. Moving these things to the Declarator solves both of these issues.

| | | | | | | | | | | | | | | | | | | MSVC now supports the __is_assignable type trait intrinsic, 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. Patch by Dave Bartolomeo!

* [OpenCL] Complete image types support.Alexey Bader2016-04-081-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [OpenCL] Adding reserved operator logical xor for OpenCLAnastasia Stulova2016-02-031-0/+3
| | | | | | | | | | | | | | | | | | | This patch adds the reserved operator ^^ when compiling for OpenCL (spec v1.1 s6.3.g), which results in a more meaningful error message. Patch by Neil Hickey!

* [OpenCL] Disallow taking an address of a function.Anastasia Stulova2016-01-051-1/+16
| | | | | | | | | | | | | | An undecorated function designator implies taking the address of a function, which is illegal in OpenCL. Implementing a check for this earlier to allow the error to be reported even in the presence of other more obvious errors.
