Require that all of the parameter types of function be complete.

Normally, parameter types are only required to be complete when a function is called or defined, but to mangle functions with certain calling conventions, the mangler needs to know the size of the parameter list. In this situation, MSVC doesn't emit an error or instantiate templates. Instead, MSVC mangles the function as _foo@0, i.e. zero bytes of parameters, which will usually result in a linker error. Clang doesn't implement this behavior, and instead attempts to error at compile time.

Check whether we're in an extern inline function and referring to a variable or function with internal linkage (C11 6.7.4p3).

This is only a warning because we used to silently accept this code, but in many cases it will not behave correctly. This is not enabled in C++ mode because the restriction language is a bit weaker (C++11 [basic.def.odr]p6) and so while there may still be user mistakes, most of the time we can't prove that there are errors.

handleFixedPointConversion - Fixed point operations between fixed point types and integers or other fixed point types do not fall under usual arithmetic conversion since these conversions could result in loss of precsision (N1169 4.1.4).

These operations should be calculated with the full precision of their result type (N1169 4.1.6.2.1).

Simple conversion between integer and floating point types.

Used when handling the OpenCL conditional operator where the condition is a vector while the other operands are scalar.

OpenCL v1.1 s6.3.i and s6.11.6 together require that the scalar types are either integer or floating type. Between the two operands, the type with the higher rank is defined as the "result type". The other operand needs to be promoted to the same type. No other type promotion is allowed. We cannot use UsualArithmeticConversions() for this purpose, since it always promotes promotable types.

Convert scalar operands to a vector that matches the condition in length.

Used when handling the OpenCL conditional operator where the condition is a vector while the other operands are scalar.

We first compute the "result type" for the scalar operands according to OpenCL v1.1 s6.3.i. Both operands are then converted into a vector of that type where the length matches the condition vector type. s6.11.6 requires that the element types of the result and the condition must have the same number of bits.

Base::TransfromCXXOperatorCallExpr doesn't traverse the callee so we need to remove its DeclRefExpr from the DRSet.

Base::TransformInitializer skip ConstantExpr so we need to visit them here.

ConstantExpr are the first layer of implicit node to be removed so if Init isn't a ConstantExpr, no ConstantExpr will be skipped.

CXXConstructExpr with a single argument are getting skipped by TreeTransform in some situtation because they could be implicit. This can only occur for the top-level CXXConstructExpr because it is used nowhere in the expression being transformed therefore will not be rebuilt. Setting AllowSkippingFirstCXXConstructExpr to false will prevent from skipping the first CXXConstructExpr.

◆ tryGCCVectorConvertAndSplat()

static bool tryGCCVectorConvertAndSplat	(	Sema &	S,

	)

static

Attempt to convert and splat Scalar into a vector whose types matches Vector following GCC conversion rules.

The rule is that implicit conversion can occur when Scalar can be casted to match Vector's element type without causing truncation of Scalar.

		QualType	vectorTy,
		unsigned &	DiagID
	)

static

Try to convert a value of non-vector type to a vector type by converting the type to the element type of the vector and then performing a splat.

If the language is OpenCL, we only use conversions that promote scalar rank; for C, Obj-C, and C++ we allow any real scalar conversion except for float->int.

OpenCL V2.0 6.2.6.p2: An error shall occur if any scalar operand type has greater rank than the type of the vector element.

Parameters

scalar - if non-null, actually perform the conversions

Returns: true if the operation fails (but without diagnosing the failure)
